【摘要】 大豆优化施肥,即适量少施氮,增施磷钾和接种根瘤菌可提高大豆产量和油分含量。适量少施氮可增加大豆产量 4.2%-6.1%,油分增加 0.08-0.25 百分点。增施磷钾可增加大豆产量3.3%-7%,油分增加0.27-0.41百分点。单独使用抗旱拌种剂或叶面肥对大豆产量和油分含量影响不大。采取优化施肥配合使用拌种剂和叶面肥可增加大豆产量 11.3%-15.6%,油分含量增加0.44-0.63个百分点。更多还原

【Abstract】 The optimum fertilization, namely, applying a little amount of nitrogen, more potassium and phosphor inoculating a lump germ on soybean could increase yield and oil content. Right a little amount of nitrogen could increase soybean yield 4.2%-6.1% and oil content 0.08%-0.25%. Potassium and phosphor fertilization can increase soybean yield 3.3%-7% and oil content 0.27%-0.47%. The seed-dressing for drought-resistance and foliar fertilizer had a little influence on soybean yield and oil content. Applying optimum fertilization, seed-dressing medicament and foliar fertilizer on soybean could increase soybean yield 11.3%-15.6% and oil content 0.44%-0.63%.更多还原
