| 摘 要： | 应用吸附试验方法对砂姜黑土和潮土的固钾能力进行了研究。结果表明，砂姜黑土固钾能力远大于潮土。几种作物的钾肥肥效亦表明，砂姜黑土区施用钾肥增产效果明显，并且对油料作物的增产幅度大于禾本科作物。钾还具有增强抗病、增加豆科作物根瘤等功能。

| Abstract: | Potassinm fixation comparison belween Shajiang black soil and fluvo-aquicsoil by tising adsorption test method showed that capacity of K fixation of Shajiangblack soil was much higher than that of fluvo-aquic soil. Results from crops response toK fertilizer also indicated that there was a siginificant yield-increasing effect on K appli-cation with the of yiele-increasing of oilseed crop being higher than that of cereal crop.Potassium also-has some functions on disease-resisting and nodule -increasing. |
