摘　　要：选用调花丰产素１、调花丰产素２和矮壮素三种植物生长调节制剂对二次结实板栗的雄花数、雌花数、枝长、枝粗、第一次果结蓬数和第二次果结蓬数等作用效应进行试验，结果表明，三种制剂使二次结实板栗新梢长生长降低１５．６３％、枝粗增加１６．６８％以上；二种调花丰产素处理使雌花数增加５９．１０％以上，雄花数降低 ２１．５６％以上；此外，试验结果证实调花丰产素对二次结实板栗的两次结篷数量具一定调节作用。Experiments were carried out on effect of flowering regulator No 1, No 2 and chlormequat chloride on male and female flower amount, branch elongation and thichening, setting percentage of first and second bearing, etc. of bibe -aring Castanea mollissima. The result showed that the treatment of three plant growth regulators could decrease current shoot growth by 15.63% while increase branch elongation by 16.68%. The two flowering regulators had effect of increase in female flower by 59.1% and of decrease in male flower by 21.56%. Besides, the result proved that flowering regulators had effect of regulation on bearing percentage of the two settings.
