1. Grasp the reasonable planting density to avoid the reduction of ventilation and light transmission in the field. 2. Use a drop-free film. The drop-free film incorporates several surfactants into the formulation to allow water molecules and film surfaces to flow into the surface without the formation of water droplets. The use of a drop-free film shed can increase the light intensity in the shed and increase the temperature of the shed. 3. Reflect the light curtain. Use a 2mm wide and 3m long aluminized film reflective curtain, hung on the north side of the shed to make it vertical, which can increase the ground by 40% and the shed temperature by 3-4°C. In addition, laying a silver-gray mulch on the ground can also increase the light intensity between plants. 4. Uncover the coverings such as grasshoppers in time, and extend the number of hours of light as much as possible. Generally, the weather should be more than 8 hours, even if it is cloudy for 4 hours. Keep yin and clear to prevent physiological wilting. 5. Pay attention to the shed film to eliminate fog and water droplets in the shed to increase the glazing rate and increase photosynthesis. The timely use of photosynthetic nutrient film fertilizer in germination and seedling stage can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit.
