| 摘 要： | 摘要：2004－2006年在甘肃甘南州夏河县桑科乡开展豆科和禾本科牧草不同草种组合混播试验研究，结果表明,建植第1年(2004年)组合Ⅱ甘肃红豆草（Onobrychis viciaefolia cv.Gansu）、阿尔冈金苜蓿(Medicago sativa cv.Algonguin)、垂穗披碱草(Elymus nutans)和无芒雀麦(Bromus inermis)]产草量最高，比组合Ⅰ(甘肃红豆草、阿尔冈金苜蓿和垂穗披碱草）、组合Ⅲ（甘肃红豆草、阿尔冈金苜蓿和无芒雀麦）和组合Ⅳ（甘肃红豆草和阿尔冈金苜蓿）分别多产干草379、446和369 kg/hm2，组合Ⅱ与其他组合之间差异显著(P<0.05)。建植第2年（2005年）组合Ⅰ、组合Ⅱ、组合Ⅲ和组合Ⅳ干草产量分别为2 489、2 856、2 715和2 976 kg/hm2，各组合之间差异不显著(P>0.05)。建植第3年（2006年）组合Ⅳ（甘肃红豆草、阿尔冈金苜蓿）鲜草、干草产量最高，比组合Ⅰ多产干草3 635 kg/hm2，各组合之间差异显著(P<0.05)。 |

| Abstract: | In order to study the planting technique of mixed grassland,a series trials of combinations of different grass species(legume and gramaneae) at Sangke town,Xiahe County were conducted during 2004-2006.Results from the study showed that in the first planting year(2004),yield of hay and fresh grass of the combination Ⅱ(the mixture of Onobrychis viciaefolia cv.Gansu,Medicago sativa cv.Algonguin,Elymus nutans and Bromus inermis) was the highest,and significant(P<0.05) higher than those from combination Ⅰ(the mixture of O.viciaefolia cv.Gansu,M.sativa cv.Algonguin and E.nutans),Ⅲ(the mixture of O.viciaefolia cv.Gansu,M.sativa cv.Algonguin and B.inermis) and Ⅳ(the mixture of O.viciaefolia cv.Gansu and M.sativa cv.Algonguin);and the hay yield was higher by 379,446 and 369 kg/ha,respectively.However,in the second planting year(2005) the yields of combinationⅠ,Ⅱ,Ⅲ and Ⅳ were 2 489,2 857,2 715 and 2 977 kg/ha,respectively.There were no significant differences between the combination Ⅰ and Ⅲ;between combination Ⅱ and Ⅳ.In the third planting year(2006),the yield of hay and fresh grass of combination Ⅳ was the highest and significant(P<0.05) higher than that of combination Ⅰ by 3 635 kg/ha.There were significant differences among the four combinations. |
