我省位于北方高寒地区,牲畜无青饲料时间长达200天左右,占全年的一半以上。为使牲畜在冬、春季能够吃到青饲料,大量推广青贮玉米,是发展畜牧业特别是养奶牛业不可缺少的重要措施。我省除经全国牧草饲料作物品种审定委员会审定通过的龙牧1号和龙牧3号两个青贮玉米可在全省推广外,当前尚缺乏适应我省西部牧业地区特点的抗旱型的品种或杂交种。为解决这一问题,我所进行了选育工作。
The province is located in the alpine region of northern China, livestock without green feed for up to 200 days, accounting for more than half of the year. In order to make livestock feed green feed in winter and spring and popularize silage corn, it is an indispensable and important measure to develop animal husbandry, especially dairy cow. Except that the two silage maize varieties Longmu No. 1 and Longmu No. 3 examined and approved by the Animal Husbandry and Veterinary Crops Examination Committee of the whole country can be popularized in the whole province, there are still a lot of drought-resistant varieties that are suitable for the characteristics of western pastoral areas in our province Or hybrids. To solve this problem, I carried out breeding work.
