- Title:
- EFFECTS ON OPTIMUM FERTILIZATION AND CHEMICAL CONTROL TOOIL CONTENT AND DROUGHT RESISTANCE OF SOYBEAN
- Keywords:
- Soybean ; Optimum fertilization ; Chemical control ; Soybean oil content ; Drought resistance

- 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 。
- Abstract:
- T he optimum fertilization, namely , applying a little amount of nitrogen, more potassiuphosphor inoculating a lump germ on soybean could increase yield and oil content .Right a little amount ofnitrogen could increase soybean yield 4.2%-6.1 %and oil content 0 .08%-0 .25%.Potassium and phos-phor fertilization can increase soybean yield 3.3%-7%and oil content 0.27%-0.47%.The seed-dress-ing for drought -resistance and foliar fertilizer had a little influence on soybean yield and oil content .Ap-plying optimum fertilization , seed-dressing medicament and foliar fertilizer on soybean could increase soy-bean yield 11.3%-15 .6%and oil content 0.44%-0.63 %.
