从改进整地和除草方法来获取长远的最大利益,己由土壤少耕而得到实现。它使投入的肥水有可能得到充分利用,从而使发展中国家可以充分开发新的高产品种。与此相反,小型农户则依赖传统的耕作方法,或被指导去采用那些整地、除草需大规模翻动土壤的技术,这些技术使投入的肥水不可能得到充分利用。因此,新品种的生产潜力很少能得到发挥。这些技术常常对农田生态系施加很大压力,在长期的生存竞争中,对作物生产增加了风险。本文是建立在整地中翻土越少、杂草的问题就越少的观点上的。 Gaining the best long-term benefits from improved land preparation and weeding practices has been achieved through less tillage of soils. It makes it possible to make full use of the fertilizers that it inputs so that developing countries can fully develop new high-yielding varieties. In contrast, small-scale farmers rely on traditional methods of farming or being guided to technologies that require large areas of soil to be trimmed and weeded so that they can not be fully utilized. As a result, the potential for production of new varieties is seldom achieved. These technologies often exert great pressure on farmland ecosystems, adding to the risk of crop production in the long-term competition for survival. This article is based on the point of view that less soil is turned into soil and fewer weed problems.
