摘要
研究了羊草地切根松土、退化草地松土补播和耕耙压播建立人工草地等三种机械化改良工艺，在此基础上将羊草地切根松土犁、松土补播机和牧草播种机三为一体优化设计在一个通用机架上，实现了多功能机型，并通过较大面积的性能试验和生产性能考核，各项试验结果达到了预期的研制目标。
According to machenical principle, we studied the techniques for cutting the rhizome of Leymus chinense, loosen improvement of grassland and cultivating grassland for establishing artificial grassland as a base for our project. Setting above three techniques to one body, me made the multi-purpose machine. After testing its function and productibility in large scale, the machine achieved pro-purpose design with improving grassland.
