| 摘 要： | 通过花椰菜氮、磷、钾"3414"田间试验,获得了花椰菜氮、磷、钾的肥料效应函数,其中一元二次效应模型分别为:Y=2009+44.6N-1.14 N2(R=0.998)、Y=2417+28.99P-3.89P2(R=0.973)、Y=2412+29.02K-1.27K2(R=0.702);试验的理论最佳施肥量,N为21.2 kg/667m2;P2O5为4.6 kg/667m2;K2O为10.5kg/667m2;结果表明:氮、磷、钾合理配施不仅可使花椰菜获得高产,而且有助于提高Vc含量和降低硝酸盐含量.

| Abstract: | The response function of fertilization in N,P,K were obtained by fertilizer experiment for "3414" of N,P,K in Brassia oleracea var.botrytis.The regression equation difference were separately Y=2009+44.6N-1.14 N2(R=0.998),Y=2417+28.99P-3.89P2(R=0.973),Y=2412+29.02K-1.27K2(R=0.702);The theory optimum rate of application of N,P2O5,K2O were separately 21.2 kg/667m2,4.6 kg/667m2 and 10.5 kg/667m2.The results showed that the adequate fertilization could obtained not only high yield,and that could improved Vitamin... |
