黔西北农业园区生菜最佳施肥配方研究
|
摘要
采用"3414"肥效试验,结合黔西北农业园区生菜(Lactuca sativa var ramosa Hort.)生产实际,通过N、P2O5、K2O施用量与产量关系建立数学模型,并模拟寻优提出生菜最佳施肥量。结果表明,N2P2K2处理(N、P2O5、K2O施用量分别为210、90、150 kg/hm2)产量最大,极显著高于N0P0K0不施肥处理;N素、P素、K素对产量的作用由大到小依次为N、K、P;通过一元二次回归方程回归分析得出纯N施用量为174.77kg/hm2、P2O5施用量为92.63 kg/hm2、K2O施用量为181.04 kg/hm2时产量分别达到最高,为27 226.79、27 499.26、27 158.40 kg/hm2。
By using testing methods of "3414" fertilizer efficiency experiment,basing on the production fact of lettuce(Lactuca sativa var ramosa Hort.) production in Northwest Guizhou Agricultural Park, the mathematical model of the relationship between N,P2 O5,K2 O and yield was established, and the optimum fertilization per unit yield of lettuce was proposed by simulation. The result showed that N2 P2 K2(the amplication amount of N、P2 O5、K2 O was 210,90,150 kg/hm2 repectively) had the largest yield, and was extremely significant higher than N0 P0 K0(no fertilizer). The effect of N,P and K on yield was N,K,P from most significant to least significant. The largest yield was 27 226.79 kg/hm2,27 499.26 kg/hm2 and 27 158.40 kg/hm2 by regression analysis of unitary quadratic regression equation, when the amounts of N,P,K applied were 174.77 kg/hm2, 92.63 kg/hm2,181.04 kg/hm2 respectively.
