【摘要】 应用计算机图像处理技术研究了鼠道犁对土壤的扰动规律。图像分辨率分别为４３０μｍ和３５．６８μｍ。试验结果表明，鼠道周围不同区域受到的压缩、松动、剪切变形等扰动不同，而等效直径小于１５０μｍ的孔隙不论在任何位置均基本不受扰动。更多还原

【Abstract】 The turbulence of soil around the hole produced by a mouse-type plow was studied by means of computer image processing techniques,the resolution ration of image are 430 μm and 35.68 μm,It shows that there are different turbulences in different zones around the hole:compact of soil,loose of soil,soil shearing and change of soil texture. The soil porosity equivalent diameter less than 150 μm around the hole isn’t effected by thd mouse type plow.更多还原
