摘要
核桃树由于授粉受精不良,树体营养不良,低温晚霜以及病虫为害等原因,造成落花落果现象严重,对产量影响很大。采用良种壮苗,合理培植授粉树,适地适树建园,加强土肥水管理,增强树体营养水平,去雄疏果,人工辅助授粉,及时整形,细致修剪,防治病虫等综合防治对策,效果较好。
Due to lack of full pollination, low temperature, frost and pest attacking, blossom drop has caused severe loss of yield. Techniques for rejuvenation, rational pollinizer, right tree for right site, soil and water management, artificial pollination, training and pruning, and integrated pest control were developed.
