花柰的主要害虫有蚜虫、桃蛀螟、桑白蚧等,这些害虫有逐年加重的趋势。因冬季灭虫,可收到事半功倍的效果.此时害虫越冬比较集中,抵抗力差,易于消灭,措施如下:①蚜虫常在柰树的枝条芽腋中越冬,因此可在花柰落叶后,剪除病枝、枯枝,集中烧毁,大部分害虫可杀死。②在树皮上的越冬害虫,如桃蛀螟、桑白蚧,可刮去虫体或刮除老粗皮,集中烧毁。③枯枝、落叶、烂果、荒草中常有害虫越冬,将其清除干净,集中烧毁,消灭虫源。④通过深翻改土,把害虫翻到土壤深处,
Scape main pests are aphids, peach borer, mulberry white scale, etc., these pests have increased year by year trend. Due to the winter pest control, can receive a multiplier effect.At this time the pests overwinter more concentrated, poor resistance, easy to eliminate, the measures are as follows: ① aphids often wintering in the arbor axillary branch tree, it can be deciduous, Cut off diseased branches, dead branches, concentrated burned, most of the pests can kill. ② overwintering pests in the bark, such as peach borer, mulberry white scale, you can scratch the worm body or scratch the old bark, concentrated burned. ③ dead branches, deciduous, rotten fruit, weeds are often overwintering pests, to clean it, concentrated burned, eliminate the source of insects. ④ through deep changes in soil, the pests turned to the depths of the soil,
