First, the adjustment method of light should be scientifically managed according to the different light intensity and illumination length of different vegetables. Xiguang vegetables include melons, solanaceous fruits, beans and root vegetables; low-light-resistant vegetables include leafy vegetables, onion and garlic; and weak-light vegetables include mustard and edible fungi. In addition to reasonable arrangement of sheds and indoor crop layouts, the corresponding adjustment methods should be adopted. 1, the method of improving the light intensity: First, the artificial light can be supplemented. In winter or rainy days, with daylighting, the daily lighting time should be based on the type of vegetables and weather conditions. Conditional mercury fluorescent lamps complement the illumination better. Second, the reflected light can be used to improve the lighting conditions. If the inner wall of the greenhouse is painted white, and the polyester reflective film is hung near the back wall of the greenhouse, the light intensity in the greenhouse can be increased. 2, the method of shortening the sunshine time: For short-day sunshine vegetables such as cucumber, when the sunshine treatment is shortened at the seedling stage, the nighttime temperature is reduced to 15-17 degrees, which can promote the differentiation of female flowers and increase the yield. Therefore, during the early spring seedling raising of cucumber, short daylight treatment can be carried out by means of late peeling and early covering of grass curtains. 3, the method of weakening the light intensity: In the summer high temperature season, you can reduce the light intensity by covering the sunshade net, or planting some sun crops such as bergamot loofah, loofah, bitter gourd. Second, the temperature adjustment method 1, the method to improve the insulation of the greenhouse: First, the use of low temperature, anti-aging insulation film, practice shows that the drop film is better than no drip film insulation, infrared barrier film, multi-functional film Better insulation than polyethylene film. The second is multi-layer coverage. Two curtains are hung in the shed, and the sheds are buckled inside, and the straw curtains are covered, which obviously increases the temperature of the shed. 2, the method of increasing soil temperature: First, erect a bed in the shed, or 20 cm from the ground. The second is to use hot brewing crops or electric hotbed seedlings. The third is to dig cold trenches outside the greenhouse. The fourth is to cover the shed with a mulch. 3, reduce the temperature inside the shed: First, you can take ventilation to cool down. When the indoor temperature in the summer reaches 30 degrees, ventilation can be taken to cool down. The second is to cover the sunshade net and the non-woven fabric to cool down. The third is watering and cooling. Third, the water regulation method To reduce the indoor temperature of the shed, the furrow irrigation method can be used, should be carried out in the morning or evening on a sunny day, and should be ventilated when watering. It is best to use the drip irrigation method to maintain the soil permeability. Fourth, the gas adjustment method 1, carbon dioxide gas adjustment method: ventilation, laying organic fertilizers and other hot crops, the application of carbon dioxide gas fertilizer and other methods to adjust the indoor carbon dioxide concentration. 2, toxic gas control methods: improper management of the shed, often produce chlorine, ammonia, nitrous acid, sulfur dioxide and other toxic gases and affect the normal growth of crops. Control measures: First, use safe and reliable agricultural film and plastic products; old plastic products cannot be stacked in the shed to prevent toxic gases from being generated at high temperatures. Second, the fully decomposed organic fertilizer should be applied, and the fertilizer should be applied immediately after applying the fertilizer (as little as possible). Third, do not stack chemical fertilizers, pesticides, plant hormones, chemical herbicides and other items in the shed.
