内蒙古土默川平原不同牧草产量与品质差异研究
摘要：以不同皮燕麦（avena sativa l.）和苜蓿（medicago sativa l.）品种为试验材料，采用田间随机设计，研究其草产量及品质差异，探讨其对内蒙古土默川平原的适应性。

结果表明，皮燕麦的草产量、粗灰分含量均高于苜蓿；而粗蛋白含量则是苜蓿较高。

表现较好的皮燕麦品种为蒙燕1号和坝燕4号。

蒙燕1号的子粒产量较坝燕4号高（两品种分别为4 264.7、3 293.9 kg/hm2）；而坝燕4号草产量较蒙燕1号高，其鲜草和干草产量分别高6 558.0、2 821.1 kg/hm2。

苜蓿品种中紫花苜蓿是高产优质品种。

to study the hay yield， grass quality and adaptability to tumochuan plain in inner mongolia. the results showed that the grass yield and crude ash content in husk oats were higher than those from alfalfa， and protein content was on the contrary. the better variety of husk oats were mengyan 1 and bayan 4. the grain yield of mengyan 1 was higher than bayan 4 （4 264.7 kg/hm2 and 3 293.9 kg/hm2， respectively）. the fresh grass and hay yield of mengba 4 were 6 558.0 kg/hm2 and 2 821.1 kg/hm2， respectively， which were higher than those from mengyan 1. the quality of lucerne was the best among the varieties of alfalfa. the study provided the theoretical reference to rich forage species of tumochuan plain.
