摘　　要：采用正交设计法Ｌ９（３４），就尿素、过磷酸钙、调花丰产素３个因子各水平协同对板栗的雄花数、雌花数、枝长、枝粗、结蓬数共５个指标作用效应进行试验。结果表明：３因子中过磷酸钙、调花丰产素为影响板栗雌花、结蓬数及新枝增粗生长的显著作用因子，而尿素作用效应则不显著。其相应的协同作用最佳组合为０ｋｇ的尿素，１．０ｋｇ的过磷酸钙，１００ｍｇ·Ｌ－１的调花丰产素。The effects of urea,calcium superphosphate and flowering regulation and increasing yield agent were experimented on male flower,female flower,branch length,branch thickness and fleabane number of Castanea mollissima by orthogonal design method L9(34).The results showed that,calcium superphosphate and flowering regulation and increasing yield agent were the dominant factors affecting number of female flower,fleabane number and thickness growth of new branch of C. mollissima.
