  4. 防鸟:尤其在南方,有很多网房,可以起到防鸟的作用,同时起到以上的作用。对于葡萄、樱桃等果蔬种植区,果实成熟时鸟类的危害也很大。覆盖防虫网后,在通风的同时起到防鸟的作用。
  4. Bird-proof: Especially in the south, there are many net houses, which can play the role of bird-proof, and at the same time play the above role. For fruit and vegetable growing areas such as grapes and cherries, birds are also harmful when the fruit is ripe. After covering the insect-proof net, it plays the role of bird-proof while ventilating.
  当然,很多人不愿意盖防虫网,因为它会影响夏天的通风,导致室内温度过高。但一般情况下,需要因地制宜,根据种植或养殖需要具体设计是否增加防虫网。
  Of course, many people are reluctant to build insect-proof nets because they can affect summer ventilation and lead to excessive indoor temperature. However, in general, it is necessary to tailor the measures to local conditions, and to design whether to add insect-proof nets according to the needs of planting or breeding.
