摘要
众所周知 ,坡耕地水土流失是比较严重的 ,选择适当的耕作方式 ,对于减轻坡耕地水土流失具有重要意义。文章着重研究了横坡耕种、密植耕作和坡改梯耕种方式。研究表明 ,它们均具有一定的水土保持作用 :横坡耕种和茶园密植种植方式水土保持的作用明显 ,但缓坡耕地好于陡坡耕地 ,坡改梯是陡坡耕地水土保持的有效方式。
For solving the problem of serious loss of soil and water on sloping plowland,it is very important to choose proper plowing method.In this paper, some plowing methods such as contour plowing,densely plowing,terraced plowing, etc. have been studied, and it is found that they all have effects on soil and water conservation to some extent.The effects of contour plowing and densely plowing are obvious, especially on moderate plowlands, while the terraced plowing method is very effective on steep plowlands.
