Study and Analyze the Construction Advantages of Intelligent Greenhouses

At present, there are many hidden dangers in the construction of greenhouses in China. The main reason is that the traditional solar greenhouses account for too much, especially the solar greenhouses built by farmers. Because of the low cost, the simple structure of the investment is also 7 to 80,000 yuan. Lower operating costs. Let many vegetable farmers see the business opportunities, and excessive automatic spontaneous construction of solar greenhouses. However, the solar greenhouses built by farmers themselves are simple in structure and have a weak ability to resist natural disasters. In addition, there are few greenhouse modernization facilities. The opening and closing of the heat-insulating curtain and the adjustment of the ventilation window basically rely on manual operation, which not only requires labor intensity, but also requires farmers to have rich experience. Otherwise, cold damage, heat damage and phytotoxicity may easily occur.

The disadvantages of unified solar greenhouse construction: low cost, low land utilization, and simple structure

 1. Low cost, simple structure: Although the solar greenhouses are cheap, they also have insurmountable weaknesses.

 2. Low land utilization rate: Generally, solar greenhouses are cluster constructions, ranging from 10 to 20 clusters and more than 50 to 60 clusters. Because the greenhouses need to maintain a sufficient distance between the front and rear of the greenhouse so that the interior can obtain sufficient sunlight, plus the outdoor walking and transportation roads, the total area covered by clusters of solar greenhouses accounts for about 50% of the total area, while the deep wall is dug. The solar greenhouse is even lower, about 40%.

 3. Mechanized operation Low energy: Solar greenhouses are difficult to modernize, especially difficult to mechanize. Each solar greenhouse has a small area, most of which are below one mu. It is difficult for the agricultural machinery to operate rationally and efficiently indoors, and it is even more difficult to carry out operations such as product grading and packaging.

4. Unscientific planting: Solar greenhouses commonly use ground soil to grow vegetables, and long-term use of chemical fertilizers has led to a decline in soil quality.

Intelligent multi-span greenhouse construction advantages: high land utilization, advanced planting equipment, high yield

 Solar greenhouses is only a phased mode of vegetable cultivation in China. Compared with traditional solar greenhouses, modern intelligent multi-span greenhouses have a much higher land utilization rate, generally more than 80%, and are not limited by saline sand land; in addition, they can provide indoor crops with advanced planting technologies and equipment. The best growing environment. Large greenhouse space, the top and four walls can be light, the height of the vegetable growth is highly limited, can be three-dimensional planting, so the yield is very high. Moreover, it has a high degree of automation, standardized operations, computer management, and high worker productivity.

 Smart Glass Greenhouse refers to a greenhouse that uses glass as a lighting material and belongs to a kind of greenhouse. In a cultivation facility, a glass greenhouse has the longest service life and has the following advantages:

1. Large lighting area and uniform illumination;

2. The use of long time, high intensity;

3. Has a strong anti-corrosion, flame retardant;

More than 4.90% light transmission, and does not decay with time;

 At present, the proportion of modern intelligent multi-span greenhouses in China's planting area is still very low, about 7%. The reason for this is the large investment and high operating costs.

 The developed countries have been able to promote the use of smart greenhouses in large numbers, and they have been able to operate in a healthy and stable manner for decades. This is because they have formed a complete social service system for greenhouse design, construction, construction and operation; greenhouse construction and greenhouse structure The supply of materials has been standardized and specialized, which is the basis for reducing the cost of smart greenhouses.
