| 摘 要： | 以高油夏大豆鲁豆9号为试验材料,以N,P,K三要素不同配比和不同施肥期为处理,探讨N,P,K不同施肥方式对夏大豆产量和脂肪含量的影响,研究出有利于夏大豆高产、高油的施肥措施。结果表明,N,P,K配合施用可显著提高夏大豆产量和脂肪含量;改N肥底施为花荚期追施,适当控制N肥用量,增加P,K肥用量,可使夏大豆产量和脂肪含量同步提高。

| Abstract: | The high fat summer soybean Ludon 9 was applied as experimental material,various NPK ratios and fertilization period as treatment,effect of various fertilizations to yield and fat level was studied.It is concluded that reasonable NPK ratio could considerably improve yield and fat level of soybean and measures of N base fertilizer substituton by dressing at flowering to podding setting stage,reasonable application dosage and increase of P and K application dosage could improve yield and fat level simultaniously. |
