盐土的开发和利用在工程引淡改良方面已取得了明显的洗盐改土效果.但由于盐渍上地区严重缺水,致使大片滩地围而不垦,垦而复荒.为加速盐渍土的农业利用过程,我们在沿海中度盐渍化土上进行了覆盖植棉试验,以求达到边利用边改良,提高开发效益之目的.材料和方法(一)试验设计试验分田间小区和室内盆栽两部分,各 设3个处理:(1)覆盖地膜(60%);(2)覆盖杂草(250kg/亩);(3)对照.各处理均重复3次, Saline soil development and utilization has been made in the project to improve the light of salt has made significant effects of soil and water improvement.But due to the serious shortage of water on the salt, resulting in a large beach around the land reclamation, reclamation and reclamation .To speed up the saline soil Of the process of agricultural use, we in the coastal salinization of soil cover cotton experiments carried out in order to achieve the use of edge while improving and improving the development of the benefits of materials and methods (a) test design test points field and indoor Potted in two parts, each with three treatments: (1) cover the plastic film (60%); (2) cover the weeds (250kg / mu); (3) control Each treatment were repeated 3 times,
