摘要: 采用四元二次回归正交旋转组合设计,研究密度、氮肥、磷肥和钾肥4个栽培因子对泉豆7号产量的影响。结果表明:各试验因子对泉豆7号产量的影响大小顺序为氮肥>磷肥>钾肥>密度。泉豆7号产量要获得超过2 147.25kg·hm-2的最佳农艺措施为:种植密度35.48万37.82万株·hm-2,尿素79.02~88.71kg·hm-2,钙镁磷肥438.75~484.50kg·hm-2,氯化钾64.17~75.27kg·hm-2。

Abstract: The effects of planting density and different NPK on the yield of Quandou 7were studied by the design of orthogonal rotational regression combinatorial design.The results showed that the order of affecting yield of Quandou 7was nitrogenous fertilizer>phosphate fertilizer>potassium fertilizer>planting density.The optimal cultural methods for yields above 2 147.25kg·hm2 was as followed:planting density was(3.548-3.782)×105 plants,nitrogenous fertilizer was 79.02-88.71kg·hm-2,phosphate fertilizer was 438.75-484.5kg·hm-2 and potassium fertilizer was 64.17-75.27kg·hm-2. -
