当前,在我省紫花苜蓿生产中,存在着两个较突出的问题,其一是结籽和采种问题,在一定程度上制约紫花苜蓿种植面积的扩大和推广;其二是在东北、内蒙和包括我省在内的高寒地区,还存在着紫花苜蓿安全越冬问题,直接影响着产量和品质,而且间接地影响我省畜牧业的发展。经连续四年的探索,我们认为影响紫苜蓿安全越冬是由多方面因素构成的,其中主要是选择适于本地的耐寒品种;掌握适宜的播种期;正确掌握适宜的刈割时间、次数;合理的留茬高度等。 At present, there are two prominent problems in the production of alfalfa in our province. One is the problem of seed and seed collection, which restricts the expansion and promotion of the planting area of ​​alfalfa to some extent. The other is that in the northeast, Inner Mongolia and Inner Mongolia Including our province, alpine region, there are still safe overwintering alfalfa problem, a direct impact on the yield and quality, but also indirectly affect the development of animal husbandry in our province. After four consecutive years of exploration, we believe that the safety of overwintering the alfalfa is due to many factors, of which the choice is mainly for the local cold-tolerant varieties, proper sowing time, appropriate cutting time and frequency, rational Stubble height and so on.
