| 摘 要： | 通过在一定氮磷肥基础上配施不同水平钾肥的研究，证明配施钾肥能增加多叶老芒麦地上和地下生物量及种子产量，同时还有提高老龄多叶老芒麦粗蛋白和粗脂肪的含量，配施钾肥增加了多叶老芒麦种子中性洗涤纤维含量，而对酸性洗涤纤维几乎没有影响。

| Abstract: | On the basis of application of certain combined nitrogen and phosphorus fertilizer,the effect of the dressing potassium fertilizer with different level was studied.The results showed that the above and underground biomass,seed yield,crude protein and crude fat content of Elymus sibirilus cv.Duo Ye were increased when potassium fertilizer was dressed.The neutral detergent fiber contnt of seed of Elymus sibirilus cv,Duo Ye was also increased,but the content of acid detergent fiber was nearly affected. |
