草原地区的粮食与饲料生产,对发展当地畜牧业具有重要意义。内蒙古中、东部地区自然条件严酷,地广人稀,粮料生产的机械化作业水平较高,耕地大都采取轮休轮种的利用方式。一般,轮休地趁雨季高温进行伏翻压青,不仅可以松土蓄水,而且翻扣到土壤下面的杂草在微生物作用下腐烂分解,还可以提高肥力,加速土壤改良。但是,光稃香茅等根茎性禾草和其他根蘖性害草(如二裂委陵莱,风毛菊等)在机械耕翻后却迅 Grassland areas of food and feed production, the development of local animal husbandry is of great significance. In the middle and eastern Inner Mongolia, the natural conditions are harsh and sparsely populated. The mechanized operation of grain production is relatively high. Most of cultivated land adopts the rotation utilization pattern. In general, taking advantage of the rainy season to take advantage of the high temperature during the fall of autumn and winter, not only can be loose soil water storage, but also turned over to the soil below the weeds under the action of microorganisms decay, but also can improve fertility and accelerate soil improvement. However, rhizome grasses and other rhizome grass and other bushy weeds (such as two cracked Cerambycore, Feng Maoju, etc.) plowed after the mechanical plowing
