摘要
针对目前正安格林镇引种核桃落果明显,导致果实产量受到严重影响的不良现象,该文分析了正安格林引种核桃落果的原因,并提出了相应的防治对策:1正安格林平均气温和积温基本能满足引种核桃对温度的需求,但核桃开花挂果期正安格林降水过多,雨日数多,湿度大,日照不足是引起核桃落果的重要原因;2缺乏有效的栽培技术,正安格林核桃种植土壤管理上采用大水大肥,加上核桃密度栽培过密,造成树冠果园郁闭,光照条件差,导致坐果率降低。
The paper analyzed the climatic conditions of the introduced walnuts serious fruit-drop.The causes was found and the controlling measures were put forward：（1）the average temperature and accumulative temperature in Gelin town of Zhengan County can meet the demands of production of introduction walnuts,But the more precipitation,more rain days,high humidity and lack of sunlight was the important cause of introduction walnuts in its fruit-drop;（2）Too much water and fertilizer in the soil,overcrowding for walnut cultivation was the another cause of introduction walnuts in its fruit-drop.
