研究、了解牧草的生态学特性,是牧草引种驯化工作的基础和前提。它可以预见、评价牧草引种驯化的效果,确定牧草推广的地区范围,指导牧草的栽培、管理和利用等工作。但由于这方面的工作开展得很少,所以,往往使牧草引种驯化工作带有很大的盲目性。例如,大柳种羊场自1952年建场以来,曾多次从国外或我国北方草原区引进牧草良种,但由于对其生态特性了解不够,往往多因不能适应本地的酸性土壤、炎热的气候、干
Studying and understanding the ecological characteristics of forage grass is the basis and prerequisite for the introduction and domestication of forage grass. It predicts and evaluates the effect of introduction and domestication of forage, determines the range of forage promotion and guides the cultivation, management and utilization of pasture. However, due to the fact that there is very little work carried out in this area, it often leads to great blindness in the introduction and domestication of forage grass. For example, since its establishment in 1952, Daliushu sheep farm has repeatedly introduced pasture varieties from abroad or in grassland areas of northern China. However, due to its insufficient understanding of ecological characteristics, it often fails to adapt to the local acid soil and hot climate. dry
