1 防虫网的挑选 防虫网是一种新式农用掩盖资料,常用标准有25、30、40、50目等,有白色、银灰色等不同色彩,应依据各种不同果树应用防虫网掩盖的意图,挑选不同类型的防虫网,一般以防虫为意图,选用25目白色防虫网,以防霜冻、防落果、防暴雨等为意图,可选用40目白色防虫网,各地可依据出产需要和出产实践挑选不同类型的防虫网。
1 Selection of insect control net Insect prevention net is a new type of agricultural cover up data. The commonly used standards are 25, 30, 40, 50 mesh, white, silver gray and other different colors. According to the intention of using insect prevention net to cover different fruit trees, different types of insect prevention net should be selected. Generally, 25 mesh white insect prevention net should be selected for the purpose of insect prevention. 40 mesh white insect prevention net can be selected for the purpose of frost prevention, fruit falling prevention and rainstorm prevention Insect net, different types of insect net can be selected according to production needs and production practice.
2 防虫网的掩盖方法 分棚式和罩式2种。棚式是将防虫网直接掩盖在棚架上,四周用泥土和砖块压实,棚管(架)间用卡槽扣紧,留大棚正门揭盖,便于进棚操作管理,主要合适蓝莓、杨梅等高价值生果栽培的应用。罩式是将防虫网直接掩盖在果树上,内用竹片支撑,四周用泥土按实,可单株或多株,单行或多行,悉数用防虫网掩盖,操作简便,大大节省网架资料和节省出资,缺点是人为操作管理不便,这种方法合适短期的、季节性防霜冻、防暴雨、防鸟害等,如柑橘果实老练期和枇杷幼果期的防霜冻,杨梅、蓝莓老练期的防果蝇和防鸟类为害等。

2. There are two kinds of covering methods of Insect Net: shed type and cover type. The shed type is to cover the insect proof net directly on the shed frame, compact the surrounding with soil and bricks, fasten the gap between the shed pipes (frames), and leave the front door of the shed uncovered, which is convenient for the operation and management of the shed, mainly suitable for the application of high-value fruit cultivation such as blueberry and bayberry. The cover type is to cover the insect net directly on the fruit tree, and support it with bamboo pieces inside, and press the soil all around. It can be single or multiple plants, single or multiple lines. All of them are covered with insect net, which is easy to operate, greatly saving the grid data and investment. The disadvantage is that it is inconvenient for human operation and management. This method is suitable for short-term, seasonal frost prevention, rainstorm prevention, bird damage prevention, etc., such as old citrus fruit Frost prevention in the period of training and young fruit of loquat, fruit fly and bird damage prevention in the period of aging of Bayberry and blueberry, etc.
3 防虫网的掩盖时间 依据不同生果防虫网掩盖的意图和要求,确定相应的防虫网掩盖时间,如柑橘果实老练期的防霜冻,要求在霜冻(冷空气)降临前掩盖防虫网,一般在10月底或11月初开端掩盖,如杨梅果实老练期防果蝇和防暴雨等,一般在果实老练前1个月开端掩盖防虫网,即5月上中旬。
3. Covering time of insect net According to the intention and requirements of different fruit nets, determine the corresponding nets covering time, such as the frost prevention in the aging period of citrus fruit, which is required to cover the nets before the frost (cold air) comes, generally at the end of October or the beginning of November, such as the fruit fly prevention and rainstorm prevention in the aging period of bayberry fruit, generally at the beginning of one month before the fruit aging, that is, in May In the middle.
4 防虫网掩盖的管理 防虫网掩盖前,尤其是罩式掩盖,果园要全面做好施肥、病虫防治等各项田间管理工作。掩盖期间,密封网室,四周压实,棚顶及四周用卡槽扣紧,如遇5~6级以上大风,需拉上压网线以防掀开。平常进出大棚要随手关门,以防害虫飞入棚内,并经常查看防虫网有无撕裂口,一旦发现,要及时修补。如防虫网用于防果实霜冻,在霜冻前,要将防虫网与果实离隔,以防止因果实紧贴防虫网形成霜害损失。掩盖结束后,要及时用冲水清洗防虫网,待晾干后入库储藏,以备重复使用。
4. Before the management of insect control net cover, especially the cover type cover, orchard should do well in the field management of fertilization, pest control and so on. During the cover up period, the mesh chamber shall be sealed and compacted around, and the roof and surrounding shall be fastened with clamping groove. In case of strong wind above 5-6 level, the mesh pressing line shall be pulled to prevent it from being lifted. Usually, when entering or leaving the shed, close the door at will to prevent pests from flying into the shed, and check the insect net frequently to see if there is any tear. Once found, repair it in time. For example, if the insect net is used to prevent fruit frost, the insect net shall be separated from the fruit before frost to prevent frost damage caused by the fruit clinging to the insect net. After the cover up, the insect net shall be cleaned with flushing water in time and stored in the warehouse after being dried for reuse.
