在东欧中部 ,形成层始成土覆盖了相当大的一部分地表。本研究的目的是 :①调查土壤结构的变化 ,特别是植被覆盖期间地表性质的变化 ;②测定地表结皮对土壤可蚀性的影响 ;③及时研究入渗率的变化 ;④鉴定植被覆盖时的高侵蚀危险期。研究方法 :①分别测定种床准备前后与作物生长
In central eastern Europe, the formation of strata formed a substantial part of the surface. The purpose of this study is to: (1) investigate the changes in soil structure, especially the changes in the surface properties during vegetation cover; (2) determine the effects of surface crusts on soil erodibility; (3) study changes in infiltration rates in time; (4) High risk of erosion. Methods: ①Determination of growth before and after seedbed preparation and crop growth respectively
