摘要
利用三因素二次回归通用旋转组合设计,研究花生—大蒜轮作模式下N、P、K配比对花生产量及农艺性状的影响,确定花生最佳施肥方案。结果表明,施肥量与施肥方式的不同对花生生育性状的影响较小,当施肥量为纯N 195kg/hm2、P2O5157.5kg/hm2、K2O 240kg/hm2时,花生产量最高,为7030.05kg/hm2。
With the quadratic regression rotational combination design of three factors, the alloca tion effect of N, P, K on peanut yield and agricultural characters under peanut and garlic rotation mode was studied to determine the optimum fertilizer showed that, the difference of fertilization rate and mode appli had cation scheme on peanut. The results little effect on the growth nut. The highest yield of peanut was 7030.05 kg/ha when the fertilization rate to peanut was P2O5157.5 kg/ha, K2O 240 kg/ha.
