摘　　要：为了提高板栗产量及一级果率，１９９７年在太行山板栗产区进行了化学药剂去雄试验。初步的试验结果表明：板栗疏雄醇可使２９％～５０％的雄花序早期脱落，一级果率增加１１８．１８％～１６３．６４％，产量提高２０％～３４．９４％；疏雄醇Ａ的效果优于疏雄醇Ｂ；疏雄醇Ａ的最佳施用期为５月１０日，疏雄醇Ｂ的施用时期则以５月２０日为好。The experiment of male inflorescence thinning was carried out by chemical method in Taihang mountainous regions where product Chinese chestnut in 1997. The preliminary result showed that male inflorescence thinning alcohol can make the male inflorescence fall away early, the rate of first class fruit increased by 118 18%～163 64%,raised the yield by 20%～34 94%. The effect of male inflorescence thinning alcohol A is better than male inflorescence thinning alcohol B.The best period of using male inflorescence thinning alcohol A is May 10th, but for male inflorescence thinning alcohol B is May 20th.
