梨为异花授粉果树,极大多数品种自交结实事很低,为使品种正常受精着果,必须对主栽品种配置授粉品种,借助昆虫传粉,促进受精结实,如果授粉树配置数量不足或不均匀时,也不能正常受精。在开花期遇低温、多雨或大风天气影响传粉昆虫的活动时,也会造成受精困难,需要进行人工辅助授粉来补足,这已
Pear is cross-pollination of fruit trees, most of the varieties self-intersection of practical things is very low, in order to make the varieties of normal fertilization, the main cultivars must be configured with pollination varieties, with insect pollination to promote fertilization and fruiting, pollination tree if the configuration is insufficient or not Even, it can not be normal fertilization. Encountering pollinating insects during periods of low temperature, rainy or windy weather during flowering can also result in fertilization difficulties and require artificial assisted pollination to compensate
