中耕除草、深翻轮休等传统耕作制度,常常造成严重的水土流失。实行免耕种地,作为水土保持的战略对策,是当务之急。免耕法不仅能有效的保持水土,而且能提高土壤肥力,增产增收,节省劳力和减少投入。目前的障碍,主要是思想保守,沿袭守旧,免耕制度不配套。建议奖励实行免耕的农户;研制价廉、高效和无污染的除草剂;先办试点,以点带面,全面铺开;用行政和经济手段逐步废除传统耕作制。
The traditional farming system such as cultivating and weeding grass and turning the wheel deeply and deeply often causes serious soil and water loss. The implementation of no-till farming, as a strategic measure for soil and water conservation, is a top priority. Tillage not only can effectively maintain soil and water, but also can improve soil fertility, increase yield, save labor and reduce input. The current obstacles are mainly conservative thinking, conservative old-fashioned, no-till system is not complete. It is suggested that farmers who implement no-till farming should be encouraged to develop herbicides that are cheap, efficient and non-polluting. They should start with pilot projects that will be rolled out in a point-by-point manner and gradually abolish the traditional farming system with administrative and economic means.
