1 发展饲草高粱的必要性1.1 发展饲草高粱是农业结构调整的需要关于草业的发展,早在20世纪80年代初我国著名科学家钱学森先生就提出“立草为业”的概念。20多年来,特别是90年代以来我国先后引入不少优良草种,饲草作物面积逐年扩大,但我国的牧草需求量和生产量仍存在较大差距。并且供需之间的缺口还将随着我国畜牧业的发展继续拉大。其原因:一是社会对种草的认识不足;二是缺乏优质高产的农田人工草地品种。
The necessity of developing forage sorghum 1.1 Development of forage sorghum is the need of agricultural structure adjustment As for the development of prataculture, as early as the early 1980s, our famous scientist Mr. Qian Xuesen put forward the concept of “weeding as industry”. Over the past 20 years, especially since the 90’s, China has introduced many excellent grass species and the area of forage grass has been expanding year by year. However, there still exists a big gap between the demand and the output of forage in our country. And the gap between supply and demand will continue to widen with the development of animal husbandry in our country. The reason: First, the community lack of understanding of the grass; second is the lack of high-quality high-yielding artificial grassland cultivated land.
