1. Increase the light. (1) Clean the film on the film every day to ensure the high transmittance of the plastic film; hang a 1 meter wide aluminized mirror reflective film at a distance of 5 cm from the back wall of the solar greenhouse to improve the illumination of the crops in the northern part of the cultivation. The illuminance within 0 to 3 meters from the reflective film can be increased by 9% to 40%. (2) Grasshoppers should be uncovered early and try to extend the time for vegetables to see light; in cloudy and snowy days, according to the external temperature conditions, grasshoppers can be uncovered at noon for a short time, so that vegetables can be exposed to scattered light, which cannot be uncovered for several days. Grasshopper. (3) When the snow or smog weather exceeds 2 days, appropriate artificial light supplementation can be performed. The use of plant growth lamps is better.
2. Keep warm and cold. (1) Install a thermal insulation covering of appropriate thickness. The plastic film or color strip cloth on the outside of the grasshopper mainly prevents the grasshopper from being wetted by rain (snow) to reduce the heat preservation effect, and at the same time, it is easy to remove the snow. (2) Add built-in insulation. In the case of not affecting the light transmittance, a layer of heat preservation curtain is installed in the shed; a thick cotton curtain is placed in the buffer room and the greenhouse, and an isolation doorway is arranged in the greenhouse, and the number of entering and exiting the greenhouse is minimized. (3) Take measures to increase ground temperature. The application of organic fertilizer and organic materials, sorghum, mulching, wide and narrow cultivation can increase the ground temperature by 3 to 4 °C. (4) Use artificial auxiliary heating. In the case of continuous snow or smog weather, when the temperature of the shed is continuously lower than 5 °C, the hot air stove or electric hot air may be used to compensate the temperature, or the geothermal line may be pre-wired, and the ground temperature may be increased if necessary.
3. Water and fertilizer management. In winter facilities, the water management of vegetables should be controlled, and the irrigation should be carried out by micro-drip irrigation. When the haze weather occurs, try not to fill the water. Fertilization is based on organic fertilizer, and appropriate application of nitrogen, phosphorus and potassium compound fertilizer and calcium fertilizer. When the smog weather comes, the leaves can be sprayed with 0.3% potassium dihydrogen phosphate plus 0.3% calcium nitrate plus 1% glucose solution.
4. Adjust the plants. When the plant growth is weak, appropriate flower thinning and fruit thinning, and timely harvest early, reduce the burden on the plant; when the plant grows vigorously, more appropriate fruit retention, and appropriate late harvest, to prevent excessive growth of nutrients.
5. Integrated pest management. Covering the Mulch Film to reduce surface evaporation and reduce indoor humidity; timely removing old leaves and diseased leaves; using smoke agents or dusts to control pests and diseases.
6. Avoid the danger of sudden clearing after many days of fog. It is necessary to pay attention to taking intervals and alternately revealing them. It is not possible to uncover all the grasshoppers immediately, and to avoid the loss of water and wilting of crop leaves under strong light. If the leaves are found to be wilting, they should be covered with grasshoppers. After the plants are restored, they will be gradually removed.

Wiggle wire lock is designed to be used with poly lock base cap- sold separately. Greenhouse wiggle wire and base care are an effective method of attaching your poly film roof and or shade cloth. The greenhouse wiggle wire lock will hold form 4 mil to 20 mil thickness of material. Use one wire to hold the roof in place and then add a second wire to hold your shade cloth. When it is time to remove the shade cloth, you will not disturb the roof plastic.
Universal Base (WIG2000)- used on the curved surface, i.e. the arch for attaching the end wall covering.
Standard Base (WIG1000) - used along the straight lengths of your greenhouse.
