摘要
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 。
The paper studied the effect of chemistry catkins thinning on Chinese chestnut yield and quality and also analyzed the differences on fruit quality between pre storage and post storage The results showed that the yield has closely connection with the rate of thinning Chemistry catkins thinning increased chesnut yield about 32 77%,cut down unfruitful shell ratio 4 2%,increased the weight of each fruit about 17 6%,increased the quantity of fruit grains 38 77% It could help chesnut become ripe 7～15 days earlier than usual and improve fruit quality in storage
