| 摘 要： | 2006～2007年在合作市那吾乡格河自然村和舟曲自然村,进行甘肃红豆草和阿尔冈金苜蓿人工草地混播研究,结果表明：在高寒地区红豆草和苜蓿的混播不宜作为收种草地利用,但作为收草利用是一种较好的混播模式.在播种第二年混播草地干草产量达15 359kg/hm2,高出当地燕麦1.76倍,新增产值达15 773元/公顷,比当地燕麦高3.15倍;第一茬干草含粗蛋白18.12％,第二茬含粗蛋白16.39％,共增产粗蛋白2 843.51kg/hm2,是种植燕麦的2.8倍,效益极为显著.

| Abstract: | In this study, the economic efficient of mixture sowing of alfalfa （Medicago sativa L. Algonguin） and sainfoin （Onobrychis Viciaefolia Scop. cv. ＂ Gansu＂） in Gehe and Zhouqu village, Nawu town, Hezuo city, was evaluated from 2006 to 2007. The results showed that the mixture of alfalfa and sainfoin was unsuitable for seed harvest, while it could be good mixture for grass harvest. In 2007, the dry yield of the mixture grass was 15 359 kg/hm2, which was 1.76 times the yield of local oat and the production value got to 15 773Yuan/hm2. The crude protein for hay was 18.12% in first crop, and it was 16.39% in second crop. Overall, the technology of the mixture sowing had significant economic and ecological benefits. |
