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
The author set 60 standards in Anji County, Zhejiang Province and Shaxian County, Fujian Province to study the optimum fertilization for Phyllostachys pubescens. Orthogonal design was used to rank field trials. The results of the first year showed that the order of importance of three factors of bamboo fertilization was N> P> K; N played a major role. The optimum amount of three elements per acre N6.9 kg, P_2O_54.2 kg, K_2O2.7 kg; the ratio of the three elements: N: P_2O_5: K_2O = 1: O.6: 0.4
