High-yield, high-efficiency and six-cultivation cultivation techniques for greenhouse vegetables
1. Change the ordinary membrane cover to drip-free membrane cover. The use of a non-dropping membrane enables the water droplets to flow into the ground along the membrane surface, without forming water droplets to wet and damage the plants, and also reducing the “water source†that causes vaporization of water vapor in the greenhouse. This lays a foundation for lowering the temperature. During the film coating process, the film must be tensioned and leveled to prevent the vicious circle of “water droplets-water vapor-water dropletsâ€. 2. Live seedlings were changed to transplant seedlings for nutrition. The benefits of transplanting seedlings for nutrition and seedlings are as follows: First, the roots of the plants are not susceptible to damage when transplanted. The second is basically no seedlings, so as to facilitate direct plant growth. Third, the plants are nutritionally adequate. Fourth, transplanting is convenient. Planting water must be sufficient when transplanting. 3. Change flat planting to ridge planting. The ridge plant can enlarge the light receiving area and raise the ground temperature, and the second can form a deep, loose upper layer that is conducive to the growth and development of the vegetables. Promotes root growth. The three can enhance the ability to fight drought, drain water, and reduce water. 4. Change the common planting method to cover the film cultivation, cover the film to help warming and moisturizing, early sowing, enhance resilience, avoid loss of soil and fertilizer, reduce pests and diseases, accelerate decomposition of fertilizers to maintain soil loose structure, promote early growth of strong seedlings, and stabilize high yields. 5. Change spray pesticides and water to use more dust and aerosols to prevent pests and diseases. Greenhouse greenhouse cultivation of vegetables, pests and diseases occur frequently, spray more water and drug times, humidity, in order to improve the control effect, reduce the humidity within the greenhouse, the need to use more dust, more use of aerosols, dust, which will greatly reduce the use of spray water The humidity brought by it is high, and it is easy to cause the disadvantages of the disease, which has a good effect of reducing humidity and preventing disease. 6. Changing the ventilation at noon was repeated several times. High-performance and high-efficiency sunlight greenhouses. The highest indoor temperature can reach above 32°C during the winter sunny days from 12:00 to 14:00. At this time, open the skylight to release the air. Since the outside temperature is low, the temperature difference between the interior and exterior is large. After a short time, the room temperature is reduced. Below 25°C, the sunroof should be closed to increase the temperature in the greenhouse. When the room temperature rises to about 30°C again, the skylight should be re-opened to release the air. This ventilation management should be repeated several times to maintain the room temperature at about 25°C. Due to repeated heating, air release and dehumidification, the indoor moisture content is effectively eliminated, CO2 gas is replenished, and the room temperature is maintained at a suitable temperature for the plants. The lower limit can effectively control the development and spread of pests and diseases.
