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。 In order to increase the yield and the first-level chestnut yield, 1997, Chestnut production area in the Taihang Mountains chemical removal test. Preliminary results showed that: Chestnut dioescin can make 29% ~ 50% of the male inflorescence early fall, a fruit rate increased 118.18% ~ 163.64%, the yield increased by 20% to 34.94%; sparse male The effect of alcohol A is better than that of sparselyrostenol B; the best application period of drospirenol A is May 10, while that of drospirenol B is May 20.
