1、掩盖前必定要土壤消毒,杀死残留在土壤中的病菌和害虫,堵截传达途径,防虫网的四周要压严压实,防止害虫潜入产卵。
1. Before cover up, the soil must be disinfected to kill the remaining bacteria and pests in the soil, block the transmission way, and the four sides of the insect control net must be tightly compacted to prevent the pests from sneaking into the spawning.
2、实行全生育期掩盖,一般掩盖如小白菜生育期短,下足基肥即可,生育期间不再追肥,不给害虫侵入时机。
2. Cover the whole growth period, such as short growth period of pakchoi, enough basal fertilizer, no topdressing during growth period and no time for pests to invade.
3、首要应用于夏秋叶菜的出产。应选用耐热抗病的良种,再加上防虫网掩盖就可以取得更好的掩盖作用。
3. It is mainly used in the production of summer and autumn leaf vegetables. We should choose the good varieties with heat resistance and disease resistance, and then we can get a better covering effect by using the insect net.
4、小拱棚掩盖培养蔬菜时,拱棚高度要高于作物高度,避免菜叶紧贴防虫网,给网外的跳甲等害虫取食菜叶、产卵于叶面带来或许。

4. The height of the arch shed should be higher than the height of the crop when the small arch shed is used to cover the cultivation of vegetables, so as to avoid the cauliflower from clinging to the insect control net, which may bring about the possibility for the insect pests outside the net to eat the cauliflower and lay eggs on the leaf surface.
5、防虫网掩盖尽管防虫作用好,但当气温较高时,网内气温、地温均较网外高1℃左右,给蔬菜正常出产带来必定影响。因此,在7-8月份,气温特别高时,运用防虫网要调控网内温度,如添加供水次数,保持网内湿度,以湿降温。
5. Although the effect of the net is good, when the temperature is high, the temperature inside the net and the ground temperature are about 1 ℃ higher than that outside the net, which will affect the normal production of vegetables. Therefore, from July to August, when the temperature is particularly high, the temperature in the network should be controlled by using the insect control network, such as adding water supply times, maintaining the humidity in the network, so as to cool down by humidity.
