摘要: 采用四因素二次回归最优设计建立氮、磷、钾施肥及留竹密度与毛竹林竹材产量间的回归模型,同时根据投入、产出价格建立施肥和留养立竹的经济效益方程,经F检验方程拟合较好;采用产量与效益两目标函数的双频分析,得到95%置信域的毛竹林优化施肥方案是:尿素:490~609.8kg.hm-2,平均549.9kg.hm-2;过磷酸钙250.8~262.4kg.hm-2,平均256.6kg.hm-2;氯化钾43.2~123.6kg.hm-2,平均83.4kg.hm-2。优化的立竹留养密度是:2364~2590株.hm-2,平均2477株.hm-2。

Abstract: By the optimum of quadratic regression for 4 factors,the regression model between fertilization,the living bamboo density and the bamboo timber output of Phyllostachys pubescens was established in the paper,meanwhile ,the economic benefit equations of the fertilization and the standing culm based on the prices of in input and output,which were tested by F-value in goodness of fit;By bi-frequency analysis of yield and the economic benefit,the optimal fertilization and culms density scheme were obtained within the confidence interval of 95% as follows:urea490~609.8kg.hm-2 (average549.9kg.hm-2),superphosphate250.8~262.4kg.hm-2 (average256.6kg.hm-2),potassium chloride43.2~123.6kg.hm-2 (average83.4kg.hm-2),and culms density2364~
