  大棚安装防虫网是非常必要的,它可以起到四个方面的作用:一是可以有效地防治害虫,覆盖防虫网后,基本上可以免除各种害虫如白菜虫、小菜蛾、蚜虫等。二是可以预防疾病,病毒的传播会给温室种植带来灾难性的后果,尤其是蚜虫的传播。然而,在温室安装防虫网后,害虫的传播途径被切断,病毒病的发病率大大降低。三、调节温度、土壤温湿度,在炎热的夏季,用白色防虫网罩住温室,使温室早晚温度与室外空气持平,并在中午比室外空气低1℃左右;可以达到保温的效果,可以有效地减少霜冻,减少田间湿度,减少疾病,晴天可以减少温室里的水分蒸发。四、具有遮阳作用,夏季光照强度大,强光会抑制蔬菜营养生长,尤其是叶菜类蔬菜,但防虫网可能会有一定的遮阳和效果。
  Installation of insect-proof net in greenhouse is very necessary. It can play four roles. First, it can effectively control pests. After covering the net, it can basically avoid all kinds of pests such as cabbage insects, diamondback moths, aphids and so on. Second, it can prevent diseases. The spread of virus will bring disastrous consequences to greenhouse planting, especially the spread of aphids. However, after installing insect-proof nets in greenhouses, the transmission routes of pests are cut off, and the incidence of viral diseases is greatly reduced. 3. Adjust temperature and soil temperature and humidity, cover the greenhouse with white insect-proof net in hot summer, so that the temperature of greenhouse is equal to that of outdoor air in morning and evening, and is about 1 C lower than that of outdoor air at noon. It can achieve the effect of heat preservation, effectively reduce frost, reduce field humidity, reduce disease, and reduce greenhouse in sunny days. Water evaporation. Fourth, it has the function of shading. In summer, the intensity of light is strong, and strong light will inhibit vegetable vegetable nutrition growth, especially leafy vegetables, but insect-proof net may have some shading and effect.

  防虫网一般是黑白相间的,也有常见的银灰色蚜虫具有较好的驱避效果,可以根据实际使用需要选择颜色。然而,我们建议单独使用时,应选择银灰色或黑色,而当与防晒霜一起使用时,选择白色为宜,网孔一般选择20 ~ 40。
  Insect control nets are usually black and white, but there are also common silver-gray aphids with good repellent effect, according to the actual needs of the use of color selection. However, we suggest that silver gray or black should be chosen when used alone, while white should be chosen when used with sunscreen, and mesh should generally be chosen between 20 and 40.

  此外,温室还应注意以下四点:
  In addition, the greenhouse should pay attention to the following four points:
  1. 在播种或种植前,用高温窒息棚或喷洒低毒农药杀死土壤中的寄生虫蛹和幼虫。
  1. Before sowing or planting, kill the parasitic pupae and larvae in the soil with high temperature suffocation shed or spraying low toxic pesticides.
  其次,在播种时要带药入棚,并选择健康无病虫害的植物。
  Secondly, when sowing, we should bring medicine into the shed, and choose healthy plants without pests and diseases.
  三、加强日常管理,在温室大棚内外要严格关大棚门,作业前要对相关农具消毒,防止病毒的引入,以确保使用防虫网。
  3. Strengthen daily management, strictly close the door of greenhouse inside and outside greenhouse, disinfect relevant agricultural tools before operation, prevent the introduction of virus, to ensure the use of insect-proof nets.
  四、要经常检查防虫网是否有破损,一旦发现应及时修复,确保温室内没有害虫。
  4. Insect-proof nets should be regularly checked for damage. Once found, they should be repaired in time to ensure that there are no pests in the greenhouse.
