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。
Orthogonal design method L9 (34), the urea, superphosphate, Trifolium repens 3 levels of each factor synergistic chestnut male flower number, number of flowers, branch length, branch thick, knot a total of five indicators Effect test. The results showed that the three factors of superphosphate, Trifolium repens for chestnut female flower, the number of knot and the new branch thickening growth of the significant factor, while the urea effect is not significant. The best synergistic combination is 0kg of urea, 1.0kg of superphosphate and 100mg · L-1 of bilberry.
