研究了疏雄醇对板栗产量和果实品质的影响、化学疏雄对板栗贮藏前后果实品质的变化。结果表明 :产量与疏雄率存在显著地相关性 ,化学疏雄可以提高产量 32 77% ,空蓬率降低 4 2个百分点 ,单果重提高1 7 6 % ,百蓬粒数增加 38 77% ,而且提前成熟 7～ 1 5d ,并能提高板栗果实的贮藏品质 The effects of sparse androsol on the yield and fruit quality of chestnut were studied. The changes of fruit quality before and after chestnut were treated by chemical mauxiong were studied. The results showed that there was a significant correlation between yield and sparseness and savage rate. Chemical sparse male could increase yield by 32.77%, reduce emptying rate by 42%, increase single fruit weight by 176%, increase number of berberine by 38.77% And mature 7 ~ 15d early, and can improve the quality of chestnut fruit storage
