High standard intelligent glass greenhouse planting technology should have what key technologies!

Domestic intelligent glass greenhouse construction is in full swing, the hardware construction of intelligent glass greenhouse has made great progress in our country, but the soft technology includes the greenhouse planting industry chain of technology, and the supporting of planting technology has great progress space. Here are some other common technical requirements for smart greenhouses.

1. Biological control: Insect pests will inevitably occur in the production process of vegetables. Traditional agriculture generally adopts insecticides for prevention and control, but pesticide residues on fruits will endanger the health of consumers. Semi-enclosed intelligent greenhouse can minimize the use of pesticides and realize green agriculture and sustainable agriculture. Biological control technology has been introduced to avoid the use of pesticides and ensure food safety by releasing natural enemies of cultivated pests to prey on harmful insects in the greenhouse.

2. Environmental intelligent control: As the brain of the greenhouse, the environmental intelligent control system controls the operation of all the equipment in the greenhouse. It is the specific executor of the growers' cultivation strategy. It can control the greenhouse environment accurately in real time by collecting the internal and external environmental parameters of the greenhouse and converting them into electric equipment control instructions after logical calculation. Not only reliable, more efficient.

3. Carbon dioxide supplement: Carbon dioxide is the raw material for photosynthesis in plants and the source of sugar in fruits. The amount of carbon dioxide in the greenhouse drops rapidly after sunrise and is even lower than the outdoor level. When ventilation is not possible in cold weather, carbon dioxide replenishment in the greenhouse is particularly urgent. The intelligent greenhouse adopts the principle of food-grade liquid carbon dioxide, and designs a scientific gas supply system to supplement carbon dioxide evenly and effectively in the greenhouse. Thus effectively improve fruit yield and taste, increase the nutritional value of fruit, output more healthy products.

4. Integrated irrigation of water and fertilizer: plant growth requires not only water and fertilizer, but also nutrients. The integration of water and fertilizer is an agricultural technology that combines irrigation and fertilization. The integrated theory of water and fertilizer for soilless cultivation in intelligent greenhouse is the way of controlling irrigation by accumulation of solar radiation. According to the requirements of different crops, different periods, and crops under different environments, water and fertilizer supply is timely and precise. This method directly delivers nutrients to the crop base and recyles irrigation residues, greatly improving the utilization rate of water and fertilizer, avoiding agricultural non-point source pollution, protecting the environment and realizing sustainable operation of the project.

5. Winter curtain insulation system

The problem of low outdoor temperature and high heating energy consumption in winter in northern China. Intelligent greenhouse can use double layer internal insulation and facade side roll insulation system, can form a full coverage of heat barrier in winter, greatly enhance the greenhouse thermal insulation performance, reduce heating energy consumption. One of the two layers of insulation selected high permeability energy-saving new material insulation curtain, can be used for winter daytime insulation, without affecting the light at the same time to enhance the greenhouse insulation performance.
