| 摘 要： | 采用5因子4水平3重复正交试验设计L16(45)],研究了播期、密度、氮肥、磷肥和钾肥对菜用大豆品种南农9610产量的影响.结果表明,不同的播期、密度、氮肥、磷肥和钾肥处理对菜用大豆产量形成有显著影响.综合衡量不同栽培因子对产量形成的影响,得到各因素最优组合为:氮肥(纯氮)75～150 kg/hm2、磷肥(过磷酸钙)450 kg/hm2、钾肥(氯化钾)120 kg/ hm2,选择4月份天气晴朗、地势较干燥时播种,播种越早,经济效益越高,密度1 hm2 3.75×105株.不同施肥水平对菜用大豆品质也有重要影响.增施氮肥可显著提高大豆籽粒中可溶性氨基酸和蛋白质含量,降低脂肪含量;增施磷钾肥可显著提高大豆籽粒中可溶性糖含量;增施钾肥可提高脂肪含量,降低蛋白质和氨基酸含量.

| Abstract: | In this study,with field experiment,effects of sowing date,planting density,N,P and K fertilizer on yield of vegetable soybean(Nannong 9610) were studied with the orthogonal design.The results showed that treatments of sowing date,planting density,N,P and K fertilizer significantly influenced the yield of vegetable soybean.The optimum factor combinations were as follows: nitrogenous fertilizer,75-150 kg/hm2,phosphorus fertilizer 450 kg/hm2,potassium fertilizer 120 kg/hm2,sowing date,sunny days with dry soil... |
