一、人工授粉，提高坐果率 梨树的大多数品种需要异花授粉后才能结果。如果梨园内授粉树配植较少或授粉树配植不当，则必须进行人工授粉，以提高坐果率。 １、花粉采集：采集花粉一般结合疏花进行，当授粉品种的花处于初花期时采集花朵，将采集来的花取下花药，可用两手各持一 First, artificial pollination, improve fruit set rate Most pear varieties need cross-pollination to the results. If the pear orchard with less pollination planted with pollination trees planted properly, you must be artificial pollination to improve the rate of fruit set. 1, the collection of pollen: the collection of pollen generally combined with thinning, when the pollinated varieties of flowers are collected at the beginning of the flowering flowers, the collected flowers to remove the anthers can be held in both hands
