摘要
采用4因素4水平的正交试验设计,进行氮磷钾配比施肥和激素处理对白枪杆生长的影响试验。结果表明,氮肥对白枪杆苗高生长具有促进作用(sig.=0.038<0.05),对地径生长的影响则不显著;磷肥和钾肥对白枪杆苗高和地径生长影响均不显著;激素处理对白枪杆苗高和地径生长影响也不显著。
Using 4- factor and 4 levels orthogonal experimental design,the effect of N / K / P fertilization and hormone treatment on seedling growth of Fraxinus malacophylla Hemsl was conducted. The results showed that Nitrogen showed great influence on the seedling height growth（ sig. = 0. 038 〈 0. 05）,but little effect on that of basal diameters（ sig. 〉 0. 05）. Phosphorus and potash showed litter influence neither on the seedling height growth nor on the basal diameters. Hormone Treatment showed litter influence neither on the seedling height growth nor on the basal diameters.
