了解土壤胶体对NH_4~+的吸附数量、强度和机理等特征可以揭示土壤胶体的表面性质,同时也有助于氮肥的合理施用。本文研究我国从北到南几种主要土壤胶体对NH_4~+的等温吸附及NH_4~+的解吸,讨论其与土壤胶
Knowing the adsorption amount, intensity and mechanism of soil colloids to NH 4 + can reveal the surface properties of soil colloids and also contribute to the rational application of nitrogen fertilizers. In this paper, isothermal adsorption of NH_4 ~ + and desorption of NH_4 ~ + by several major colloids from north to south in China were discussed.
