大棚防虫网掩盖培养是一项增产有用的型农业新技术,有透光,适度遮光和通风的效果。还能通过掩盖在棚架上构建人工隔离屏障,将害虫拒之网外,切断害虫繁殖途径,有用控制各类害虫。
It is a new technology of increasing production and environmental protection, which has the effect of light transmission, moderate shading and ventilation. In addition, the artificial isolation barrier can be built on the scaffold to keep the pests out of the net, cut off the propagation path of pests and effectively control all kinds of pests.
大棚掩盖,可将防虫网直接掩盖在棚架上,四周用土或砖压严实,棚管间用压膜线扣紧,留大棚正门揭盖,便于进棚操作。小拱棚掩盖,可将防虫网覆于拱架顶面,四周盖严,今后浇水直接浇在网上,一直到采收,实施全封闭掩盖。水平棚架掩盖,将1hm2左右的蔬菜地,全部用防虫网掩盖起来,这种掩盖方式节省防虫网和网架,操作便利。
For the cover of the shed, the insect proof net can be directly covered on the shed frame, and the surrounding areas shall be tightly pressed with soil or bricks. The film pressing line shall be used between the shed pipes to fasten, and the front door of the shed shall be left open for easy operation. The small arch shed can cover the top surface of the arch frame with insect proof net, which is tightly covered around. In the future, water will be directly poured on the net until harvest, and the whole closed cover will be implemented. Covering the vegetable land of about 1hm2 with horizontal scaffold, all of them are covered with insect proof net, which saves insect proof net and net frame and is easy to operate.
运用大棚防虫网能够调节气温和地温。据试验,在白色防虫网下,大棚温度在早晨和黄昏与露地相等,而晴天中午高温条件下,则网内温度比露地高约1℃,大棚10cm地温在早晨和黄昏时高于露地,而在午时又低于露地。

The temperature and ground temperature can be adjusted by using the insect control net in the shed. According to the test, under the white insect control net, the temperature of the shed is equal to the open ground in the morning and dusk, while under the high temperature condition at noon on a sunny day, the temperature in the net is about 1 ℃ higher than the open ground, and the ground temperature of the shed is 10cm higher than the open ground in the morning and dusk, and lower than the open ground at noon.
防霜、防冻。早春3月下旬至4月上旬,防虫网掩盖棚内比露地气温高1~2℃,5cm地温比露地高0.5-1度,能有用避免霜冻。防暴雨、抗强风。夏日强风暴雨会对蔬菜形成机械损伤,使土壤板结,发作倒苗、死苗现象。
Frost proof and antifreeze. From late March to early April in early spring, the air temperature in the shelter covered by insect net is 1-2 ℃ higher than that in the open ground, and the ground temperature of 5cm is 0.5-1 ℃ higher than that in the open ground, which can effectively avoid frost. Rain proof and strong wind resistant. In summer, the strong wind and rainstorm will cause mechanical damage to vegetables, harden the soil, and cause the phenomenon of falling and dead seedlings.
掩盖防虫网后,由于网眼小、强度高,暴雨经防虫网撞击后,降到网内已成蒙蒙细雨,冲击力减弱,有利于蔬菜的生长。防虫网具有较好的抗强风效果。防虫、防病毒病。掩盖防虫网后,基本上能控制由于害虫的传播而导致病毒病的发作。最重要的是增产增收,进步品质。网内青菜农药污染少、无虫眼、清洁、少泥,收获期比露地提早,商品性好。
After covering up the insect net, due to the small mesh and high strength, the heavy rain falls into the net after being hit by the insect net, which has become a drizzle, and the impact force is weakened, which is conducive to the growth of vegetables. The insect net has a good effect of strong wind resistance. Insect and virus prevention. After covering up the insect control net, it can basically control the outbreak of virus diseases caused by the spread of pests. The most important thing is to increase production and income and improve quality. The green vegetables in the net are less polluted, insect free, clean and mud free. The harvest time is earlier than that in the open field.
