平衡施肥对麻竹产量及品质的影响初报

Research on Applying Fertilizer of Bamboo

设置3因素3水平正交设计L9(33)的麻竹肥料试验。其结果表明:(1)施肥对麻竹产量有极显著的增产效应,氮、磷、钾增产的主次顺序为N>P>K。麻竹产量与施肥量回归方程y=84.30X1-86.44X2+152.15X3-0.229X12+0.947X1X2-0.769X22-0.736x1x3+0.953x32+17744(X1:施N量kg/hm2,X2:施P2O5量kg/hm2,X3:施K2O量kg/hm2,Y:产量kg/hm2),且差异达极显著;(2)最佳施肥配比N:P2O5:K=1:0.51:0.58,最大产量为44491.86kg/hm2,对应的年最大产量施肥量为N:228.71kg/hm2,P2O5:115.58kg/hm2,K2O:132.88kg/hm2;(3)施肥对笋中含N、P、K含量有显著影响;(4)施肥对笋中粗蛋白含量影响极显著主次顺序N>P>

The fertilizer experiments of bamboo. The result indicated that： （1）The fertilizer quantity return to equation was that y=5.5790X1-5.5723X2＋10.1905X3-0.01517X1^2＋0.06283X1X2-0.05169X2^2-0.04865X1X3＋ 0.0626X3^2＋1175.5667, （2）The application of N,P and K could significantly increase the yield of bamboo shoot, primary and secondary order. N〉P〉K; （3）The best Matching was N3P2K3 （4）The application of N, P and K could significantly increase the content of N, P and K of bamboo shoot. （5）The application of N, P and K could significantly increase the protein of bamboo shoot.
