1. Greenhouse sunshade net cover In summer, the sunshade net is covered on the glass roof of the greenhouse. If it is a multi-family greenhouse, the sunshade net can be hung flat indoors, which is mostly used for postponed cultivation of summer vegetables. For example, solanaceous fruits, melons, legumes, and black or silver-gray shade nets that are cultivated in a greenhouse can prevent premature senescence, extend the flowering and fruiting period, increase yield, and improve fruit quality. When autumn vegetables such as cabbage, cauliflower, celery, lettuce, mustard and so on need to be bred in summer, the use of shading nets can improve the seedling rate and seedling quality.
2. Plastic shed sunshade net cover In summer, use plastic shed skeleton or cover the sunshade net on the plastic shed film. The two sides of the net should be 1.6 ~ 1.8 meters away from the ground to facilitate ventilation. The shed film is used in combination with the sunshade net, and the effect of cooling and rainstorm is better. It can also be suspended from the ground 1.2 to 1.4 meters from the ground in the greenhouse, which is not only good for ventilation, but also does not need to be covered every day. It can be used for postponed cultivation of summer vegetables in the greenhouse and nursery for autumn vegetables, and can also be used for summer cabbage, cabbage , Fu lettuce, Fu radish, Fu celery, Fu cucumber, summer Chinese cabbage, lettuce and so on.
3. Covering the sunshade net in the middle and small sheds in early spring. Covering the sunshade net in the plastic film and the shed can early plant summer vegetables. In summer and autumn, the frame of the middle and small arch sheds is used as a bracket to cover the sunshade net, and autumn vegetable seedlings, green leafy vegetables can be cultivated or autumn vegetables can be planted in the shed in advance.
4. The small flat awning net is covered with bamboo poles, wooden sticks, iron wires and other materials to form a flat or inclined shed on the rafter surface, and the shed is covered with a sunshade net. The scaffold is about 1.6 meters wide and 0.5 to 1.8 meters high. The low shed is easy to cover the shading net; the high shed is easy to operate in the shed; the inclined shed has both advantages. Mainly used for summer leafy vegetable cultivation.
5. Floating surface covering of shading net is also called direct covering, floating covering, or sloping covering, which is a cultivation method of directly covering the shading net on the sloping surface or plants. Floating surface covering can be carried out in open field, small and medium-sized sheds or greenhouses.
It is mainly used for covering vegetable emergence. For example, in the cultivation of green leafy vegetables in summer, cover the noodles with a sunshade net after sowing, and press the net at a certain distance to prevent wind, and can shade, cool, and moisturize, creating favorable conditions for seed germination and emergence. After emergence, the shading net is removed, and a bamboo arch is used to form a small arch shed or a small flat shed on the spot, and the shading net is moved to the scaffold. In addition, during the wintering period of overwintering vegetables and spring planting of spring cabbage, spring broccoli, spring cabbage, etc., a sun net floating surface is used to cover the insulation effect.
6. Cultivation and cover of edible fungi Use black shading net with high shading to cover the shed, cool down and keep warm in summer, keep warm and moisturize in autumn, and can produce edible fungi such as Pleurotus ostreatus, straw mushroom and shiitake mushroom.
