青花菜氮磷钾施肥效应研究
Effect of N, P and K Fertilizers on Yield and Quality of Brassica oleracea L. var. italica
【摘要】 运用"3414"田间试验设计,在蔬菜主产区设置氮磷钾肥料试验,获得了青花菜氮、磷、钾的一元二次效应模型分别为:Y=891+45.02N-0.884N2(R=0.858),Y=1118+37.4P-1.229P2(R=0.568),Y=1060+16.37K-0.113K2(R=0.752);青花菜最高产量的氮磷钾理论施肥量:N为385.5kg/hm2;P2O5为151.5kg/hm2;K2O为274.5kg/hm2。
【Abstract】 The response function of fertilization in N, P and K were obtained by fertilizer experiment for "3414" of N, P and K in Brassica oleracea L. var. italica. The unitary quadric equations were as following respectively. Y=891+45.02P- 0.884P2 (R=0.858), Y=1 118+37.4P-1.229P2 (R=0.568), Y=1 060+16.37K-0.113K2 (R=0.752). The theory optimum rate of application of N, P2O5 and K2O were 385.5 kg/hm2, 151.5 kg/hm2 and 274.5 kg/hm2 respectively.
