通过研究揭示水稻土大孔隙调控过程、变化机理和调控内容的规律,预测大孔隙中化学物资、水分、空气的数量、质量及其空间格局,寻求在现有栽培和耕作制度下,实现水稻土大孔隙优化调控途径。 By studying and revealing the law of macropore regulation, change mechanism and regulation of paddy soil, the quantity, quality and spatial pattern of chemical materials, moisture and air in macropore are predicted, and under the existing cultivation and tillage system, Macropores optimize the regulatory approach.
