| 摘 要： | 作者在浙江安吉县和福建沙县设置60块标准地研究毛竹林最适配方施肥。采用正交设计排列田间试验。第一年的结果表明:毛竹施肥三要素的重要性顺序为N>P>K;N起主要作用。每亩最适三要素用量为N6.9公斤,P_2O_54.2公斤,K_2O2.7公斤;其三要素比例为: N:P_2O_5:K_2O=1:O.6:0.4

| Abstract: | The author has established 60 sample plots in Anji County of Zhejiang Province and Sha County of the Northern part of Fujian Provirice to search optimum amounts and proportiorib of applied N. P. K fertilizers for the growth of Ph. Pubescens. Orthogonal design was used. The results for the first year showed that the order of importance of three essential elements in bamboo fertilization was N>P>K; the effect of N on the output of culms appeared to be more significant than that of P and K. The optimum amount of applied N. P. K fertilizers per mu(1/15ha) is as follows: N 6.9kg, P_2O_5 4.2kg and K_2O 2.7kg. The proportion of them is N: P_2O_5: K_2O=1:0.6:0.4. |
