摘要
采用"3414"施肥试验方案,研究了不同氮磷钾处理对红葱林下栽培产量的影响。通过试验,建立了红葱产量(y)与施氮量(x_1)、施磷量(x_2)、施钾量(x_3)之间的回归方程:y=1817.28+4.56x_1+4.44x_2+16.10x_3-0.34x_1~2-0.13x_2~2-0.22x_3~2+0.27x_1x_2+0.15x_1x_3+0.02x_2x_3。根据此方程,得出红葱林下栽培的经济最佳产量为2939.4 kg/hm^2,氮、磷、钾施肥量分别为44.5、59.0、51.3 kg/hm^2,氮磷钾的最佳比例为1:1.33:1.15。
The fertilization experimental scheme of ＂3414＂ was conducted to study the effects of different N,P,K treatments on understory planting ofEleutherine plicata Herb.. Through experimentation, We established the regression equation between production（y） and components of nitrogen,phosphorus and potash： y=1817.28＋4.56x1＋4.44x2＋16.10x3-0.34x12-0.13x22-0.22x3^2＋0.27xlx2＋0.15x1x3＋ 0.02x2x3. According to this equation, the maximum economic yield （MSY） of understory planting of Eleutherine plicata Herb. was 2939.4 kg/hrnz, while applied amount of N,P,K was 44.5, 59.0, 51.3, kg/hm^2 and the optimal ratio of N,P,K was 1：1.33：1.15.
