摘要: 黄淮海平原砂地土壤约有3100万亩, 是重要的低产土壤之一, 具有较大的增产潜力。本文以山东省夏津县黄河故道区为例, 初步探讨了半湿润地区风沙土的基本性质及其改造利用的途径。半湿润地区风沙土, 机械组成较细, 有一定肥力基础; 是一种高容水或中容水沙土; 沙丘或沙岗低矮易于改造利用, 适于在护田林网基础上发展果树大行距间作, 提高经济效益, 改善生态环境。

Abstract: Sandy soil in Huang-Hui-Hai plain, covering an area of 31 million mu, is an important low-yield soil with high-yield potential. Blownsand soils, distributed in ancient channel of Huang-he River in Xiajing County, Shandong Province have fine mechanical composition, mid or high water-absorbing capacity and certain fertility. Being lower sand dune or ridges, the yare easy to improve and suitable for growing fruit trees with wide spacing as long as shelterbelts have been established and thus ecologieal envivonments have been improved.
