摘　　要：早期大量落叶现象已成为制约福建梨产持续丰产优质高效的瓶颈。综合实际调查与资料查阅认为,生态环境不适、品种遗传背景、病虫为害严重、气候条件异常、树体营养失衡、管理操作失当为其主要诱发因素,提出优化产业区域布局、选育推广耐高温高湿品种、稳定土壤水分状况、均衡土壤养分供给、改善树体营养状况、严防病虫害蔓延、改进管理操作技术等防控策略。A large number of early falling leaves have become a bottleneck problem to restrict the persistent high yield and efficient quality of the pear industry in Fujian.It can be concluded that,based on the actual investigation and the pertinent literatures,unfit ecological environment,genetic backgrounds of variety,serious diseases and insect pests damage,abnormal weather conditions,imbalance trees nutrition,improper management operations were its leading-induced factors.So,we put forward the corresponding prevention and control strategies as below： optimize the regional distribution of industry,select and popularize high temperature and humidity-resistant variety,maintain soil moisture conditions,balance the supply of soil nutrients and improve the nutritional status of trees,prevent the infestation of diseases and pests,promote management and operation technology.
