摘要
Abstract
As a kind of low-lying clay soil, meadow boggy soils often suffer from excessive moisture. In order to improve its physical properties, a three-stage soil layer mixing plough was envisaged and designed, which can return the soybean stalk or wheat straw into the subsoil to achieve longer sustainability of drainage for the improvement of meadow boggy soil. The results of the manmade plots showed that the treatments with returning soybean stalks or wheat straws into the subsoil ditch, or mixed with the subsoil at the depth of 20～50 cm, meanwhile leaving the top soil undisturbed, gave a good performance on crop yields. The yield-increasing rate was -5.6～19.5% in the first year, and 1.4～13.7% in the next year. The saturated permeability of the soil in the manmade treatments was increased. The water permeability in the treatment tilled by the prototype plough was 10 times higher than that of the control.关键词
