冬牧70黑麦(Secalerale)是一种高蛋白的禾本科饲草,我国于1979年从美国引进,1985年经我场引种试验表明,它具有适应性强、耐寒、分蘖力及再生力强等特点,并具有丰产性、耐牧性、牲畜摄食率高等综合优势。据我场1986～1987年统计,当年10月至翌年4月的整个生育期中,可刈割供畜4～5次,累积鲜草亩产可达4000～5000公斤,折干物质700～850公斤左右。由于它具备了冬半年供百的优点,营养价值又高,故有“牲畜的冬令补品”之称。它和卷心菜、大头菜等品种搭配可组成冬半年的轮供组合。

According to statistics of our field from 1986 to 1987, in the whole growth period from October to April next year, 4 to 5 times of livestock supply can be mowed, the accumulated fresh grass yield can reach 4000 to 5000 kg, and the dry matter can be removed from 700 to 850 kg about. Because it has the advantages of winter for the sake of hundred, high nutritional value, it is “livestock winter supplements,” said.
