我旗地处黄土高原北部边缘,属黄土丘陵沟壑区。境内地形起伏,沟壑纵横,地广人稀,耕地70％为坡耕地,加之降雨集中,土质疏松,水土流失极为严重。为加快皇甫川流域治理步伐,1979年我旗组建了机械施工队,并开始对川塔一、二级缓坡台地和部分缓坡耕地进行了机修梯田(条田)试验。现将多机联合作业修筑条田的主要成果介绍于下。 My flag is located in the northern edge of the Loess Plateau, a loess hilly and gully region. Undulating terrain, ravines aspect, sparsely populated, 70% of cultivated land slope farmland, combined with rainfall concentrated, loose soil, soil erosion is extremely serious. In order to speed up the management of Huangfuchuan River Basin, in 1979, I set up a mechanical construction team and began to test the first and second gentle slope terrace and some gentle slope cultivated land in Changjiang River. Now multi-machine joint construction of the main achievements of the field introduced below.
