摘要: 以红翅槭A苗、B苗为供试材料,根据N、P、K 3要素不同水平设3种不同的养分比进行施肥,通过对红翅槭树木生长及生理指标测量分析,筛选相对合理的施肥配方。结果表明,不同的配方施肥均对红翅槭幼苗生长均有促进作用,N、P一定时,增加K肥有利于地径、树高的增大;K一定时,增加N、P肥有利于红翅槭A苗叶面积的增大和有利于红翅槭A苗、B苗叶绿素含量的增大。所设3个施肥处理中,促进红翅槭幼苗生长的最优配方为配方2,即每株红翅槭幼苗氮、磷、钾肥施用量分别为3、10、5g /株,对红翅槭A苗地径、树高、叶面积、叶绿素值的影响均达显著水平。

Abstract: Fertilization formulas with different levels of nitrogen, phosphorus and potassium were applied on Aceraceae fabri seedlings to select a rational formula by measuring the growth and physiological indexes. The results showed that different fertilization formulas could promote the growth of A. fabri, the ground diameter and seedling height were improved by the increase of potassium proportion with the determined quantity of nitrogen and phosphorus fertilizer; the leaf area of A. fabri seedling A and the chlorophyll content of A. fabri seedling A and B were increased by the increase of nitrogen and phosphorus application proportion with the determined quantity of potassium fertilizer. Formula- 2 (3, 10 and 5 g nitrogen, phosphorus and potassium fertilizer per plant) had significant effect on the ground diameter, seedling height, leaf area and chlorophyll value of A. fabri seedling A, it was the optimum formula for A. fabri seedlings among the three formulas in this study.
