Key technologies that smart glass greenhouses should have for planting technology
With the development of modern agricultural technology, the construction of smart glass greenhouses is in full swing. Great progress has been made in the hardware construction of smart glass greenhouses, but in terms of soft technology, it includes the technology of the greenhouse planting industry chain and the advancement of planting technology. There is a lot of space. Share with you other common technical requirements of smart greenhouses.
Biological control: Insect pests will inevitably occur in the process of vegetable production. Traditional agriculture generally uses pesticides to prevent and control them, but pesticides remaining on the fruits will endanger the health of consumers. Semi-enclosed smart greenhouses can minimize the use of pesticides, realize green agriculture, and sustainable agriculture. Biological control technology is introduced. The use of pesticides is avoided and food is guaranteed by planting natural enemies that cultivate pests in the greenhouse to prey on harmful insects. Safe.
Environmental Intelligent Control: As the brain of the greenhouse, the environmental intelligent control system controls the operation of all equipment in the greenhouse. It is the specific executor of the grower's cultivation strategy. It collects the environmental parameters inside and outside the greenhouse, through logical calculations, and converts them into electric equipment control instructions to accurately control the greenhouse environment in real time. Not only reliable, but also more efficient.
Two-way butterfly window opening system: The roof window system adopts two-way butterfly window opening method. The windows are opened on both sides of the roof ridge, and the window area is doubled compared with the traditional design. The large roof window ratio, combined with the facade window opening, uses the "chimney principle" to achieve the best natural ventilation effect and effectively reduce the energy consumption for cooling in summer. At the same time, the two-way arrangement of windows can adjust the window roof according to the real-time wind direction during the operation of the greenhouse, and achieve better natural ventilation effects.
Carbon dioxide supplement: Carbon dioxide is the raw material for photosynthesis of plants and the source of sugar in fruits. The carbon dioxide content in the greenhouse drops rapidly after sunrise, and is even lower than the outdoor level. When ventilation is not possible in cold weather, the supplementary demand for carbon dioxide in the greenhouse is particularly urgent. The intelligent greenhouse uses the principle of food-grade liquid carbon dioxide, and a scientific gas supply system is designed to provide even and effective carbon dioxide replenishment in the greenhouse. Thereby effectively increasing the yield and taste of the fruit, increasing the nutritional value of the fruit, and outputting healthier products.
Integrated water and fertilizer irrigation: Plant growth requires not only water and fertilizer, but also nutrients. The integration of water and fertilizer is an agricultural technology that integrates both irrigation and fertilization. The theory of the integration of water and fertilizer for intelligent greenhouse soilless cultivation is the way that solar radiation accumulates to control irrigation. According to the fertilizer requirements of different crops, different periods, and different environments, water and fertilizer are supplied regularly and accurately. This method directly transports nutrients to the crop roots and recycles the residual irrigation liquid, which greatly improves the utilization rate of water and fertilizer, avoids agricultural non-point source pollution, protects the environment, and realizes the sustainable operation of the project.
Curtain insulation system in winter: the problem of low outdoor temperature and high heating energy consumption in winter. The intelligent greenhouse can adopt a double-layer internal insulation and vertical side-rolling insulation system, which can form an all-round heat barrier in winter, which greatly enhances the insulation performance of the greenhouse and reduces heating energy consumption. Among them, the second-layer inner insulation uses a high-permeability and energy-saving new material insulation screen, which can be used for winter insulation during the day and enhance the greenhouse insulation performance without affecting the light.
