摘　　要：用四因素二次通用旋转回归设计研究了夏大豆山宁14号的高产栽培技术。结果表明，该品种在666．7m2种植密度1．8万株、基施氮磷钾复合肥25kg、出苗后70天追施尿素10kg、每12天浇水1次种植模式下可获得较高产量。但在生产实际中，为增加可信性，借助产量频数分析法作进一步解析，得出山宁14号666．7m2产量大于240kg的栽培方案为：密度1．2—1．3万株，基施氮磷钾复合肥12～18kg，出苗后41-45天追施尿素10kg，每9—10天灌溉1次。The four factors quadratic general rotational regression design was used to study the cultivation techniques for summer soybean variety Shanning 14. The results showed that the high yield could be obtained under the conditions of 18 thousand plants per 666.7m2, 25 kg compound fertilizer of nitrogen, phosphorus and potassium as basic fertilizer, dressing l0 kg urea after 70 days of seedlings emerging, and watering once every 12 days. The further analysis by frequency method indicated that the cultivation conditions for Shanning 14 to obtain the yield of over 240 kg per 666.7m2 were cultivating 12 - 13 thousand plants, basically fertilizing 12 - 18 kg compound fertilizer of nitrogen, phosphorus and potassium, dressing 10 kg urea after 41 -45 days of seedling emerging, and watering once every 9 - 10 davs.
