苜蓿生长性对自然环境条件的要求,过去理论上指出,只适宜中性、微碱性砂质壤土,历来苜蓿在我国北方种植面广,是养畜业中的主要优质牧草。我省土壤多属酸性粘重红壤,夏季雨量集中,如按照理论上的根据,则限制了苜蓿的种植范围,但是我省在发展畜牧业中,普遍存在着缺乏优质青绿蛋白质饲草,这种现象在冬春季枯草期表现最为突出。结合当前畜牧生产趋势,种草养畜必须有个大发展,人工栽培优质高产牧草是 Alfalfa growth on the requirements of natural environmental conditions, the past theory that only suitable for neutral, slightly alkaline sandy loam, alfalfa has long been planted in northern China, is the main livestock husbandry forage quality. The soil in our province mostly belongs to acid sticky heavy red soil, and the rainfall in summer is concentrated. According to the theoretical basis, the planting area of ​​alfalfa is limited. However, there is a widespread lack of high-quality green protein forage in the development of animal husbandry in our province. The phenomenon is most prominent in the hay season of winter and spring. Combined with the current trend of livestock production, breeding livestock must have a big development, artificial cultivation of high-quality forage is
