摘要
目的:研究氮、磷、钾和播种量4因素对半夏产量影响。方法:采用4因子3水平正交组合试验与单因素试验进行研究。结果与结论:对产量作用效果依次为播种量>氮>钾>磷;其合理施肥水平为施N48.0-96.0kg·hm-2,P2O590kg·hm-2K2O90.0kg·hm-2,播种量为3000.0-3750.0kg·hm-2。
Objective: To study the effect of N, P, K and sowing norm on yield of Pinellia ternate. Method: The effects of N, P, K and sowing norm were studied by means of 4 factors and 3 levels orthogonal design experiments. Result and Conclusion: The effects of the 4 factors decreased in following orders is sowing norm, N, K and P. Rational amounts of fertilizer and sowing norm are 48.0-96.0 kg·hm^-2 N, 90.0 kg·hm^-2P, 90.0 kg·hm^-2K, 3 000.0-3 750.0 kg·hm^-2.
