摘　　要：采用疏芽、疏雄花、环剥倒贴皮等技术措施进行对比试验,结果表明:疏芽树比不疏芽的平均每一结果母枝抽生结果枝多0.6条,每一结果枝平均混合花序增加18.1%,每一混合花序上雌花簇增加8.6%;疏雄花比不疏雄花每667?平均产量提高27.4%;环剥倒贴皮比对照第2年每一结果母枝抽生结果枝多33.0%,每一结果母枝产量提高40.0%。Such techniques as bud thinning, staminate flower thinning, girdling back inversion were used in the comparing experment. The results showed that each rnateral branch of the bud thinning tree can produce 0. 6 fruited twig more than the commen nut tree can, the average mixed inflorescence of each fruited twig increases 18. 1% , and the pistillate of the mixed inflorescence increases 8.6%. The provuction of staminate flower thinning tree increases 27.4% every 667m^2.
