传统的灌溉方式是以避免作物缺水为前提的,尽量以足够数量的水满足作物生长的需要。美国俄勒冈州州立大学生物资源教授马雷谢尔·恩利施通过近年的大量研究发现,采用限时灌溉方式,可以用有限的水量,获得省水增产的效果。 马雷谢尔·恩利施救援通过时美国俄勒冈州东部小麦产量与施水量的分析研究,发现随着施水量的增加,产量也有明显提高。但当小麦产量达到某一极限点时,灌溉效率就会开始下降,同时随着施水量的进一步增加,还会导致土壤养分流失、作物根系层通气 The traditional way of irrigation is to avoid the shortage of crops as a prerequisite, as far as possible with a sufficient amount of water to meet the needs of crop growth. According to a large number of studies conducted in recent years, Mareschel Enliss, a professor of biological resources at Oregon State University, has found that limited-time irrigation can achieve the effect of saving water and increasing production by using limited amount of water. Analysis and analysis of wheat yield and water use in Eastern Oregon at the time of the rescue by Maresheel Enlish found that output also increased significantly with the increase of water use. However, when the wheat yield reaches a certain point, the efficiency of irrigation will begin to decline. At the same time, with the increase of water supply, soil nutrient loss will be caused.
