采用高效复合肥、开特灵、寻乌稀土、植物生长调节剂等四种营养植物生长调节剂、从1990年～1991年在柑桔上进行比较试验,试验结果对柑桔提高座果率、单果平均重、叶片厚度、鲜叶及干叶重等方面均有不同程度的促进作用。这四种营养型植物生长调节剂对植物无毒无公害,适用范围广,使用简单,其中以开特灵和高效生物复合肥效果最佳,表现树势健壮,叶色浓绿,果实大而均匀,是良好的叶面追肥,具有推广应用价值。
Using four kinds of nutrient plant growth regulators, such as high-efficiency compound fertilizer, Kettering, Rare Earth Urabas, plant growth regulators, etc., comparative experiments were carried out on citrus from 1990 to 1991, The average weight of single fruit, leaf thickness, fresh leaves and dry leaf weight and other aspects have different degrees of promotion. These four vegetative plant growth regulators are non-toxic and pollution-free to plants and have a wide range of applications and simple uses. Among them, Katrine and high-efficiency biological compound fertilizers are the best, showing strong vigor, dark green leaves and large fruits Even, is a good foliar fertilizer, with the promotion and application value.
