Vegetable Insect Net Cover Cultivation Technique

First, the technical characteristics of leaf production in summer and autumn, eggplant production and application of vegetable pest nets covering cultivation techniques, can effectively prevent insects, anti-virus disease, and can ease rain erosion and improve the growth of vegetables in covered shed small environment, production (less) Pesticide-contaminated vegetables can increase the yield of summer and autumn vegetables by 30%. The quality of the products is good. It is a mature, labor-saving, productivity-enhancing, simple and practical new environmentally-friendly agriculture technology that opens up the physical physics of vegetable pest control and disaster resistance. The prevention and control of new ways have very significant social, economic, and ecological benefits. Second, cover the form 1, the shed coverage will be covered in the insect nets on the scaffolding. Firstly, the fields are finished and the foot basal fertilizers are removed. At the same time, chemical weeding and soil disinfection are performed. Then, the insect nets are covered, the four perimeters are compacted, and the ropes between the sheds are pressed against the wind to prevent winds. Afterwards, the watering is directly poured on the insect-proof nets. Closed cover. 2. The small arch shed is covered with steel or bamboo arches and arched in Daejeon. The net is covered on the top of the arches. It is fully enclosed and compacted. It covers the previous performances of weeding and soil disinfection. This method is particularly suitable for steel pipes. The promotion of the sheds in the region also serves as an insect protection and preservation vegetable. 3. Horizontal Shed Covering This covering method is to cover 3-5 mu of land and cover it with insect-proof nets. Tests have shown that this kind of net room has a large net room area, and field operations can be carried out in the net room, saving the net. And network racks. III. Application 1. The production of leafy vegetables from leafy vegetables has always been pest-producing and pesticides have been seriously contaminated. The use of pest control nets to cover cultivation can achieve pesticide-free pollution of leafy vegetables. The cauliflower covered by insect nets is more plump and white. This is the most widely used field of insect nets. 2, Solanaceae, melon production Solanaceae, melons prone to viral disease in summer and autumn, the application of insect nets, cut off the transmission route of pests, help reduce the harm of the virus. 3, autumn vegetables nursery from June to August each year, is the nursery season of autumn and winter vegetables, but also high temperature, heavy rain, frequent insect pests, seedlings difficult, seedling rate, seedling rate is low, the use of insect nets after the emergence of a high rate of vegetables, Seedlings are of good quality. Fourth, the application of points 1, before covering the soil must be disinfected to kill the bacteria and pests left in the soil, cut off the route of transmission, insect nets around the pressure to be tightly compacted to prevent pests from diving into spawning. 2, the implementation of the whole growth period coverage, general coverage, such as the short period of growth of Chinese cabbage, the next foot basic fertilizer can be, during fertility no longer top-dressing, no opportunity to invade pests. 3. It is mainly used for the production of summer autumn leaves. Should use heat and disease resistant varieties, coupled with insect net coverage can achieve better coverage. 4. When the small arch shed covers the cultivation of vegetables, the height of the arch shed should be higher than the height of the crop to prevent the leaves from sticking to the insect-proof nets, and it is possible to feed the leaves and other pests outside the net to feed on the leaves and lay eggs on the leaves. 5. Insect net coverage Although the pest control effect is good, but when the temperature is high, the network temperature, ground temperature are higher than the outside of the network by 1 °C, to bring a certain impact on the normal production of vegetables. Therefore, in the period of July-August, when the temperature is particularly high, the use of insect nets to regulate the temperature within the network, such as increasing the number of water supply, maintain the network humidity, in order to wet cooling.
