| 摘 要： | 根据两年来水稻丰产的研究结果,在水稻所需的氮磷钾营养元素中,氮素最为活跃,而且敏锐地受到人为措施的影响.水稻的氮素营养问题,不仅在于氮素的供应容量,土壤的氮素供应强度及其持续时间,也同时深刻地影响水稻器管的协调生长.

| Abstract: | Present investigation involves the rate of adsorption of ammonium by some paddy soils in solutions of 0.5,0.2,0.1,0.05,0.025 and 0.01NNH4Cl with a soil-solution ratio at 1:5.Sample used consist of seven soils collected from Southern Kiangsu with predominant clay minurals of 2:1 types and two from Kiangsi with 1:1 types.Results obtained are according to the Langmuir's and Freundlich's adsorption equations and the correlation coefficients are given. |
