目前我国奶牛,奶羊及养猪业主要集中在城市周围的郊区农牧场里。饲料地面积小,水肥条件较为优越,增加畜产品量和产值的主要途径是主要实行集约化牧草栽培,最大限度地提高单位饲料地的载畜量,所以引进和选择培育高产、优质牧草,适应集约化栽培的需要是牧草选种的当急任务。串叶松香草,分枝性强,植株高大,可达2—3米,有强大的空间优势,亩产量可达15000—20000斤以上。宿根多年生,使用年限可达10—12年。食口性好,含氮量高,特别是动物所需的赖氨酸含量较高。除过青刈饲用之外,并可青贮和制作草粉,是较为理想的集约栽培型牧草品种。 At present, China’s dairy cows, dairy goats and pig breeding industry are mainly concentrated in the suburbs of the city farms and ranches. Feeding land area is small, water and fertilizer conditions are superior, the main way to increase livestock products and output value is to mainly implement intensive forage cultivation, to maximize the carrying capacity per unit feed, so the introduction and selection to cultivate high yield, high quality forage, adapt The need for intensive cultivation is a pressing task for pasture selection. Slash leaves, strong branches, tall plants, up to 2-3 meters, a strong space advantage, the yield per acre up to 15000-20000 pounds. Perennial perennial, the useful life of up to 10-12 years. Good appetite, high nitrogen content, in particular the high lysine content required of animals. In addition to green forage for feeding, and silage and the production of grass powder, is an ideal intensive intensive cultivation of forage species.
