Method for building shallow channel and wide ridge of gentle slope cultivated land
The invention provides a gentle slope cultivated land shallow channel wide ridge building method, and belongs to the technical field of cultivated land water and soil conservation, and the method comprises the following steps: obtaining the topographic features of gentle slope cultivated land; determining a shallow channel wide ridge base line of the gentle slope cultivated land; determining shallow channel wide ridge spacing, ridge gradient, length and cross section parameters of the gentle slope cultivated land; and surface soil is cut on the slope upper side of the base line and is completely buried to the slope lower side of the base line, and a ditch-ridge structure is formed. Water flow erosion is reduced by building the shallow channel wide ridge on the gentle slope cultivated land, the width of the three slope surfaces formed by the shallow channel and the wide ridge is approximately equal to the agricultural machine operation width, agricultural machine operation is facilitated, crops can be normally planted, the cultivated land is not occupied, the formed shallow channel wide ridge has a certain gradient in the ridge direction, accumulated water in the shallow channel can be conveniently discharged, and the land utilization rate is improved. In addition, by means of collecting topographic data through the unmanned aerial vehicle, marking a base line through RTK equipment and the like, the ridge direction and the downhill gradient can be accurately controlled, and storage and dredging of water are facilitated.
本发明提供一种缓坡耕地浅渠宽埂的修筑方法，属于耕地水土保持技术领域，该方法包括如下步骤：获取缓坡耕地的地形特征；确定缓坡耕地的浅渠宽埂基线；确定缓坡耕地的浅渠宽埂间距、垄向坡度、长度和横断面参数；在基线的坡上侧切削表土，并全部填埋至基线的坡下侧，形成一个渠‑埂结构。本发明通过在缓坡耕地上修筑浅渠宽埂来减少水流侵蚀，浅渠‑宽埂所形成的三个坡面的宽度约等于农机作业幅，便于农机作业，可正常种植作物，不占用耕地，形成的浅渠宽埂在垄向上具有一定坡度，便于排出浅渠内积水，不会导致径流破垄，且本发明通过无人机采集地形数据、用RTK设备标记基线等手段，可精准控制垄向及比降坡度，有利于水的存蓄和疏导。
