摘要： 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>K。

Abstract: The fertilizer experiments of bamboo. The result indicated that: ⑴The fertilizer quantity return to equation was that y=5.5790X1-5.5723X2+10.1905X3-0.01517X12+0.06283X1X2-0.05169X22 -0.04865X1X3+0.0626X32+1175.5667,⑵The application of N，P and K could significantly increase the yield of bamboo shoot, primary and secondary order. N>P>K; ⑶The best Matching was N3P2K3 ⑷The application of N, P and K could significantly increase the content of N, P and K of bamboo shoot。⑸The application of N，P and K could significantly increase the protein of bamboo shoot.
