How to Achieve the Greenhouse Temperature Management

In the production of the agricultural greenhouse, keeping the temperature in the shed is the basic condition to keep the crops growing well.

Generally speaking, the temperature inside the shed can vary with the temperature outside. The change rule is, the higher the temperature outside the shed, the greater the temperature value inside the shed, and the lower the temperature outside the shed, the smaller the value-added inside the shed. In general, the maximum and minimum temperatures in the shed occur about two hours later than on land.

The temperature in the shed often varies with the weather and the seasons. Users can add a series of protective measures according to the change of greenhouse temperature to keep the temperature constant. The temperature difference is larger on sunny days and smaller on rainy days. The lower the temperature, the higher the daily temperature, and vice versa. In addition, users can also according to the early cultivation of vegetable varieties suitable growth temperature requirements to strengthen the temperature regulation in the shed.

At the same time, different crops have different temperature requirements. Users can adjust according to realistic conditions and crop requirements. For example, there is usually no ventilation before planting seedlings after transplanting. It is used to raise the temperature in the shed, which is conducive to the growth of crops. Not only that, but the user also according to the seasonal conditions for adjustment, early spring due to weak light, but the effect of temperature increase in the shed is also poor, can be used to cover plastic film and small arch shed measures, to improve the effect of heat preservation.

Agricultural Greenhouse

Here's how the greenhouse dehumidification problem can be solved by the planting greenhouse installation company: Water is the main factor leading to indoor humidity increase, so how to water has become an important measure to control the humidity. Winter and spring production can choose clear ditch water or water plants, dark irrigation under plastic film mulching film can be used. Water shall strictly control the water quantity, to prevent the indoor humidity is too high. The outer membrane well prevents the loss of carbon dioxide produced by internal vegetable growth, make the huts have a good heat preservation effect.

After each watering appropriate wind, timely mattock soil can reduce the soil moisture, also can reduce the air humidity. Water is the main factor leading to indoor humidity increase, so how to water has become an important measure to control the humidity. Winter and spring production can choose clear ditch water or water plants, dark irrigation under plastic film mulching film can be used. Water shall strictly control the water quantity, to prevent the indoor humidity is too high. After each watering proper lookout, in a timely manner HuaChu scarification, can reduce the soil moisture, can also reduce the humidity of the air. The greenhouse is one kind has excellent thermal insulation performance of the effect of the frame structure, it makes people can eat the anti-season vegetables. General greenhouses use bamboo structure or the steel structure of the skeleton, above a layer or multilayer insulation plastic compound, This creates a greenhouse space.

How Does the Disease Insect in Hothouse Kill Effectively?

The vegetables grown in the greenhouse grow year by year, and this environment provides a suitable place for diseases and insect pests to survive the winter. In the face of the characteristics of many diseases and insect pests, fast spread and heavy harm, which have a great impact on vegetable production, it also has a great impact on the output. Therefore, the vegetable Greenhouse manufacturer will introduce three effective measures for you:

(a) high temperature stuffy shed

Before planting Vegetables, cover the canopy with a canopy membrane and close the closed canopy for 7 to 10 days on a sunny day to raise the temperature of china glass greenhouse for vegetables above 60 ℃. In this way, the bacteria and spores and eggs on the soil surface and walls can be killed, which will reduce the source of infection during the growth of Vegetables. When be in high temperature and frowning shed, press every cubic metre shed space USES the object that sulphur powder 3 grams, sawdust 5 grams, dichlorvins smoke agent 1 gram to mix equably next rise, dark fire is ignited, airtight smoke is smoked, the effect is better, but after fumigation should be put out wind 2 to 3 days, reprepare the ground is planted.

China Glass Greenhouse For Vegetables

(2) Seed treatment

Diseases and insects are often lurking or mixed on the seeds and seedlings of vegetables. Careful treatment of the seeds before sowing can kill some diseases and insects. Common treatment methods include soaking seeds in warm soup and treating chemicals. 1. Soaking seeds in warm soup is generally soaked in warm water at 50°C to 60°C for 5 to 15 minutes. Stirring should be kept during soaking to make the seeds evenly heated; 2. The agent treatment can use 0.1% copper sulfate, 0.1% potassium permanganate or 300 Formaldehyde can be used for seed soaking, and the seed can be mixed with 50% carbendazim wettable powder in the amount of 0.3% to 0.4%.

(3) Disinfection of soil chemicals

Before sowing or planting, disinfecting the soil in the planting greenhouse can kill germs or eggs in the soil, and prevent or reduce the harm of pests in the growing season of vegetables. When sterilizing the soil, the pesticides can be selected according to the occurrence of diseases and insect pests throughout the year. Mix the medicament with an appropriate amount of fine dry soil, evenly spread it on the ground, and then plough into the soil. One-third is spread on the seedbed, and two-thirds is spread on the seed after sowing, that is, the lower cover is covered, which has obvious control effect on vegetable seedlings diseases and insect pests, but pay attention to keep the surface soil of the bed surface moist to avoid damage.

These are some effective measures for when we have pests. Let ’s follow them. I believe everyone has a headache for pests. So when we are planting, we must ensure that no matter what step is used, we can reduce the invasion of pests. Our plants grown.

Management Measures of Greenhouse Vegetables in Early Summer

With the arrival of summer, the winter and spring stubble vegetables in the greenhouse have entered the late growth stage, and the over-summer stubble vegetables have entered the early planting period. How to formulate corresponding management measures? China Glass Greenhouse manufacturer: china glass greenhouse manufacturer to share with you:

(1) Strengthen fertilizer and water

After the beginning of summer, most of the stubble vegetables in winter and spring have entered the later stage of growth, and it is inevitable that the plants will decline. At this time, management should be strengthened to maximize the benefits. It can start strengthening management from two aspects of leaf maintenance and root protection, and spray the leaves with full nutrients every 7-10 days to supply the nutrients needed for vegetable growth in time. Fertilizer can not only be used for high nitrogen fertilizer, but can be applied by Fangrun, or by potassium sulfate compound fertilizer combined with compound microbial bacterial fertilizer, so as to achieve the purpose of strengthening roots and promoting fruit yield.

Farming Greenhouse

(2) Strictly prevent diseases and insects

As winter and spring stubble vegetables, pest control cannot be relaxed, because if allowed to develop, it will not only reduce the yield and effect of the stubble vegetables, but also increase the number of pathogens in china glass greenhouse for vegetables Stubble crop production. For example, tomato leaf mildew can be controlled by spraying with pesticides such as Garenone or Shigao, and it must be sprayed strictly; for example, bacterial diseases can be controlled by copper preparation or streptomycin. With the increase of temperature, virus diseases and insect pests have become an important obstacle for winter and spring stubble vegetables and over-summer vegetables, so they must be strictly controlled.

(3) Reasonable temperature control

For the winter warm greenhouse, when the minimum temperature is stable above 15 ℃, the grass curtain should be removed in time or no longer covered at night, so as to avoid excessive night temperature and excessive consumption of nutrients, resulting in poor flowering and fruit setting. As the temperature continues to rise, the head wind should increase the amount and time of ventilation. When the top wind is difficult to control the temperature increase in the shed, the vents at the front face are pulled apart, and appropriate sunshade and cooling measures are taken to ensure the normal growth of crops. For the arch shed, the following methods can be adopted according to the actual situation to achieve the purpose of regulating the shed environment, which is conducive to the growth of vegetables: First, the plastic film is still used for the top film, and the skirt film is removed. In this way, the top film is used to cover the rain, and the lower position is ventilated and permeable. Second, the plastic film is still used for the top film, and the skirt film is removed to cover the insect-proof net. In this way, the top film is used to cover the rain, which can isolate pests and prevent pests from harming the vegetables in the shed, but the ventilation and moisture permeability in the shed are poor, and high temperature or high humidity are prone to occur. The third is to remove the skirt film, keep the plastic top film, and cover the sunshade net. This method is often used for the production and seedling of over-summer vegetables.

(4) Cultivate strong trees

The temperature is high and the plant is prone to grow long. In addition to the management of the farming greenhouse environment, it is necessary to pay attention to the control of soil and watering to cultivate a strong root system. During planting, roots can be used to apply root anti-dead biological fungus fertilizer, 80-120 kg per mu, which can not only effectively inhibit the occurrence of root diseases, but also promote rooting and inhibit the growth, which is conducive to the cultivation of strong trees . After planting the delayed seedlings, control watering and timely plowing and hoeing to loosen the soil, enhance soil permeability, and promote root development.

How to Achieve Indoor Heat Preservation Effect of Glass Greenhouse Greenhouse?

1. Generally, it is possible to adopt the cover of mulch film, as well as some multi-layer cover methods such as the deduction of small arch sheds, and movable curtain surfaces for heat insulation.

2. Many layers of grasshoppers (curtains) are often continuously added on the inside of the large perimeter so that it is not only windproof but also heat-preserving.

3. Generally, it is also possible to install fluorescent lamps in the greenhouse, generally (the lamp and the plant leaves adhere to an interval of 50cm), and it is usually enough to illuminate the light for 10-12 hours every day.

4. However, at the one end of the greenhouse, thick curtains are often hung at the entrance and exit of the greenhouse to prevent the intrusion of cool wind.

5. A masking effect can also be performed with a drip-free film.

Intelligent Greenhouse

Compared with ordinary thin film greenhouses, smart greenhouses are smarter and more convenient to use. They are a modern farming environment that integrates data collection, central accounting, and equipment active control. So what are the advantages of Intelligent greenhouse cultivation? The greenhouse manufacturer analyzes it for you.

During the operation of the smart greenhouse, the management personnel enters the data and control parameters required for crop cultivation into the computer. The smart greenhouse can complete unmanned operations, actively control the greenhouse environment, and ensure crop growth.

During the operation of the smart greenhouse, the management personnel enters the data and control parameters required for crop cultivation into the computer. The smart greenhouse can complete unmanned operations, actively control the greenhouse environment, and ensure crop growth.

1. The loss of planted crops is almost zero: compared with manual monitoring, smart greenhouses are used for planting. The obvious advantage is to ensure stable environmental conditions in the smart greenhouse, which has relatively high environmental requirements. For plants, it may be useful to avoid production losses due to human factors.

2. The quantity and quality of products that can be flexibly improved: The intelligent greenhousecontrol method is selected to ensure the environment. Compared with artificially controlled greenhouses, the output value and quality of crops are greatly improved.

3. Savings and efficiency: For breeding enterprises with certain plans, it is necessary to continue to improve the benefits of agricultural cultivation, not only to improve the output value and quality of crops but also to improve operating efficiency and reduce operating costs. After adopting intelligent control in intelligent greenhouses, it can also play a role in these two aspects. After adopting the intelligent greenhouse monitoring system, the operating efficiency is significantly improved, and the labor cost is greatly reduced. The investment and operation of the intelligent greenhouse can be fully calculated from the saved labor costs, and the intelligent economic benefits of the greenhouse control system are used. This is a long time, and the longer it is used, the lower the labor cost.

Greenhouses have a great impact on crops. Greenhouse manufacturers have found that they also have a great impact on greenhouse crops. Plants are very sensitive to high temperatures. Crops will experience lower photosynthesis when exposed to high temperatures, and their respiration will increase at night The energy consumed is relatively high, which greatly consumes the growth of the crop. Greenhouse manufacturers give an example. Just like tomatoes, photosynthesis of different brands of tomatoes has decreased slightly under high-temperature treatment, so the content of chlorophyll will also be different.

The above is the introduction of the advantages of smart greenhouse cultivation, I hope to help everyone. Xinghua JinYi Greenhouse Equipment Co., Ltd. is a high-tech enterprise integrating greenhouse research, design and manufacturing. We believe that with your support, we believe that we can meet every challenge and look forward to creating a new starting point for you to win-win with your business, and quickly embark on the road of mature development.

Which Several Respects Should the Market Research Before Greenhouse Construction Proceed with?

I. Determination of agricultural products

Farming greenhouse is used to produce high-quality, high-yield, high-value-added agricultural products such as off-season. Under market economic conditions, market demand is a process of investigation and research. First look for market demand and determine the local or domestic and international market varieties. If the product is supplied to the local market, the local dietary habits need to be considered to determine the products to be grown.

The information returned from the current aspects shows that the cultivation of special, rare, and precious green vegetables is currently selling well in the domestic and international markets. Some do not need to establish high-end greenhouses for planting, and it is still possible to use local solar greenhouses Get considerable profits. For the cultivation of common vegetables, the local market is the main, and it should be carried out in a simple greenhouse. The planting costs cannot be increased at will, resulting in no market for the products.

Investment in greenhouse cultivation is risky. There is a certain time difference between the greenhouse cultivation and the market. Once the product positioning is not appropriate, the greenhouse construction project is likely to fail halfway.

Single Span Plastic Film Greenhouse

Second, the positioning of the greenhouse-greenhouse project

The market is changing, and the greenhouse is a fixed asset investment with relative stability. The purpose of building a greenhouse needs to be redefined. The construction of greenhouses in China started relatively late, and different regions have different levels of understanding of greenhouses.

At present, the construction of many greenhouses is at the stage of government guidance and support, with demonstration as the mainstay, social and environmental benefits are relatively prominent, and economic benefits are not ideal, and there are certain comprehensive benefits.

For demonstration greenhouses, high-tech, high-input, and high-output are the characteristics of this type of greenhouse. The greenhouses and planting methods with new structures and materials at home and abroad should be adopted. The products produced should be oriented to the national and international markets. Considering the social and environmental benefits, in particular, there must be significant economic benefits, at least the role of a greenhouse leader in the local area, otherwise, the demonstration fails.

For ordinary planting greenhouses, as long as they can meet production needs, the form of the greenhouse is not important. The single span plastic film greenhouse has a simple structure, can meet the growing needs of most vegetables, fruits, and fruits, and is easy to operate, which is conducive to popularization. For high-end fully-automatic control greenhouses, it is currently inappropriate for most planting and breeding, high cost, complicated system, high operating costs, and requires special maintenance. Operators are required to have a high level of technology, which is suitable for scientific research and high value-added agricultural products. Production use.
