1. Hang a light curtain on the back wall of the greenhouse to increase the light intensity in the shed and improve the distribution of light in the shed so that the lower part of the high-vegetable vegetables will receive a certain amount of light, and the temperature inside the shed can be increased. 2. Under the premise of dismantling grasshoppers, artificial light supplement measures are adopted. Incandescent lamps, fluorescent lamps, high-pressure mercury lamps, agro-sodium lamps and other daily supplements are used to remove light before and after the daily removal of grasshoppers, so that the length of the sunlight in the shed is maintained at about 12 hours. 3. Improve the light intensity and illumination time in plastic greenhouses, make full use of light energy in vegetables in greenhouses, maximize photosynthesis, and increase material accumulation is an important way to obtain high yields of vegetables. Try to maintain the cleanliness of the plastic shed without dropping the membrane, keep it at the highest light transmittance and reduce the loss of light intensity. 4. In the period from October to early December, straw curtains should be covered as soon as possible, and from December to February the following year as the coldest season. Suddenly, after the continuous cold weather, it was clear that it could not be eager to expose the straw curtain. Instead, we should gradually remove the straw curtain. 5. The use of bacteria, fungi, actinomycetes and other aerobic microorganisms can increase the temperature of the animal's manure, wheat straw, etc. in the shed. This method is the most economical warming measure, and at the same time, a good fermentation product can also be used as a fertilizer. 6. Minimize heat loss and improve greenhouse insulation. The specific measures include floating membrane technology in greenhouses, that is, covering a layer of film on the grasshoppers to improve the insulation of the greenhouses at night; the technology of covering the entire plastic film in greenhouses, increasing the soil temperature in the greenhouse, and then increasing the temperature of the greenhouse; increasing the irrigation water temperature and avoiding irrigation Loss of heat due to low water temperature. 7. Do not dismantle grasshoppers for many days in a row. Avoid growing vegetables in the dark and consume too much nutrients. At the same time, try to expose grasshoppers on cloudy days. In order to reduce the humidity in the greenhouses, windy weather should be used for a short time to reduce the incidence of diseases. 8. Do a good job of pruning the tall trees and increase the light transmittance between the trees. 9. When the wind is too strong, pressure the film on the shed to remove the sheds as much as possible to prevent the strong wind from blowing down the sheds. When the wind is small, cover the mulch in time to keep warm. 10. In the case of a dark day, on the basis of ensuring the minimum temperature for the growth of cultivated plants, remove the straw and receive some light.
Fall Protection include Full Body Harness, half body harness(waist safety belt) and Energy Absorbing Lanyard.
