| 摘 要： | 选择7个白桦半同胞家系种子分别播种育苗,在苗木生长过程中配制T1、T2、13 3种配方的氮磷钾混合营养液定期进行叶面施肥,系统地研究配方施肥对白桦不同家系苗期生长的影响对每个家系内3种施肥处理与非施肥处理的苗木苗高、高径比、茎根比进行方差分析和多重比较,确定各个家系的最佳施肥配方.结果为:家系1、家系3、家系4和家系5的最佳施肥配方均是T2,该施肥处理能够使白桦苗高提高13.43%～35.74%;家系6和家系7的最佳施肥配方均是T3,该施肥处理能够使白桦苗高提高24.93%和26.46%;家系2的最佳施肥配方是T1.3种施肥配方均能改善白桦苗期的生长,对7个家系总体而言,T2为最佳施肥配方.

| Abstract: | The genotypes of forest trees and the optimum mixture ratio for fertilization are crucial factors for breeding superior seedlings.In this experiment,seven half-sib families were selected for the culture of Betula platyphylla seedlings.During the growth period,three different nutrient solutions,with different mixture ratios of N.P.K,were used to fertilize the seedlings on the leaf surface regularly.Hitherto,this paper for the first time reported a systematical study of the effects of the formula fertilizer o... |
