高寒山区优良牧草引种试验研究

Introduction experiment of high quality forages in alpine areas

针对甘肃省岷县特殊的自然气候条件,对5种优良牧草品种进行引进栽培试验研究。结果表明,引进的5种牧草品种适应性强,抗寒能力强,生长发育快,饲料利用价值较高。而且部分品种具有较高的营养价值,符合引进品种的目标要求,适宜在岷县地区大力推广。试验为当地选择利用优良牧草品种提供了科学依据,也为同类地区草产业的发展提供了优良的草种。

According to the special climat-environment of the experimental site, introduction trail of 5 varieties of forages with high quality from Hokodo of Japan were conducted in the alpine area with high and cold climat in the Min County of Gansu province. The experimental results indicated that the trial grasses had good adaptability, strong cold tolerance, fast growing ability and high useful value. Chemistry analysis on the forage nutrition showed that the 5 introduced forages contained relative higher nutrient materials. They accord with the introducing requirement and are suitable to be extend to Min courty and other areas with similar ecological condition.
