甘孜州半农牧区麦后复种饲用油菜引种比较试验
【目的】比较不同油菜品种的生态适应性及牦牛日采食总量,为甘孜州半农牧区推广麦后复种饲用油菜提供优良的种质资源。【方法】2011年7~10月,以四川双低油菜生产中主推品种川油36、川油58为对照,引进中国西北地区大面积推广饲用油菜品种饲油1号、华协11号,采用品种比较及牦牛舍饲试验,调查不同油菜品种生态适应性及牦牛采食速度和日采食总量。【结果】在甘孜州半农牧区引进品种饲油l号、华协11号均可正常生长,鲜草产量分别可达34296.16和30573.75kg/ha;牦牛对饲油1号的采食速度为61.19g/min·头,日采食总量为14.73kg/头,对华协11号的采食速度为62.91g/min·头,日...

Summary: | 【目的】比较不同油菜品种的生态适应性及牦牛日采食总量,为甘孜州半农牧区推广麦后复种饲用油菜提供优良的种质资源。【方法】2011年7~10月,以四川双低油菜生产中主推品种川油36、川油58为对照,引进中国西北地区大面积推广饲用油菜品种饲油1号、华协11号,采用品种比较及牦牛舍饲试验,调查不同油菜品种生态适应性及牦牛采食速度和日采食总量。【结果】在甘孜州半农牧区引进品种饲油l号、华协11号均可正常生长,鲜草产量分别可达34296.16和30573.75kg/ha;牦牛对饲油1号的采食速度为61.19g/min·头,日采食总量为14.73kg/头,对华协11号的采食速度为62.91g/min·头,日采食总量为15.15kg/头,均显著高于对照品种。【结论】饲油1号、华协11号可作为麦后复种饲用油菜品种在甘孜州生态条件下推广种植。 |

Bibliography: | [Objective]The present study was conducted to study the ecological adaptability and total daily intake quantity of forage rape (Brassica napus) in order to supply elite forage rape germplasm resources for growth after harvesting wheat in the agro-pastoral ecotone of Ganzi Prefecture. [Method]From July to October, 2011, experiment on eultivar comparison and yak intake of two introduced forage rape (Brassica napus) cultivars (Siyou 1 and Huaxie 11), extended in large area in northwest China, was carried out by using two main double-low erucic acid rape cultivars in Sichuan production as control; ecological adaptability of the two introduced cultivars, yak intake speed, and total daily intake quantity were investigated and studied. [ Result ]In agro-pastoral ecotone of Ganzi Prefecture, Siyou 1 and Huaxie 11 could grow regularly with the fresh yield of 34296.16 and 30573.75 kg/ha, respectively, yak intake speed and total daily intake quan- tity of Siyou 1 were 61.19 g/min.yak and 14.73 kg/yak, respectively, thos |
