摘　　要：对阿克苏地区核桃基腐病发病环境进行了调查,并对其进行了药剂防治试验。结果表明,核桃基腐病的发生与栽植密度、树龄、间作模式以及灌水次数有密切关系。栽植密度为（6 m×4 m）的果园发病程度较重,发病率达2.7%,盛果期（11-20 a）的核桃树发病较严重,发病率高达14.20%,不同间作模式发病率不同,核桃与小麦间作时发病率较高,达7.80%,随灌水次数增加病害发生程度也有增加的趋势,调查灌水前发病率为9.60%,第3次灌水后发病率增至15.94%。药剂防治结果表明,从施药方法上来看,刮除病斑涂抹药剂效果优于划道和直接涂抹。从药剂的效果来看,腐烂克星＋轮腐1号混合施药效果较好,防治效果达到了83.30%,病疤愈合效果39.80%,其次,自制药剂大蒜液＋10%食盐愈合效果达到了16.30%,效果较好。The objective of this study was to survey the surroundings of occurrence of walnut stalk rot and its control test.The result showed that this disease has a close relation with planting density,tree age,intercropping model and irrigation times.The occurrence extent of walnut stalk rot in the orchard with planting density of 6 m×4 m was relatively serious.The percent infection reached 2.70%,but at full-fruit stage（11-20 a） it becomes more seriously.It was different when different intercropping model was adopted.It reached 7.80% when intercroping walnut with wheat were adopted.The percent infection of walnut stalk rot was increased along with the increase of irrigation times.It was 9.60% before irrigation survey.The percent infection was increased by 15.94% after 3rd irrigation.The result of control test of fungicides showed that fulankexing＋lunfu1hao has higher effect than that of other fungicides.It is 83.3%.Garlic＋10%salt has better result,it is 16.30%.
