The effect of humic acids on fixation and release of potassium in soil was accomplished by dissolving K-bearing minerals or blocking interlayers and adsorbing K. 腐殖酸對土壤鉀素釋放和固定的影響是通過對含鉀礦物的溶解和層間堵塞以及對鉀素的吸附作用實(shí)現(xiàn)的。
The characteristic of Potassium fixation and release of the key paddy soils derived from different parent materials was studied by an simulation experiment and chemical methods. 本文通過室內(nèi)模擬和化學(xué)方法研究了廣東幾種不同母質(zhì)發(fā)育的水稻土的鉀素的固定與釋放特性。
Laboratory incubation experiments in constant temperature were implemented to study influence of humic-acid and fulvic-acid on fixation and release of potassium in cultivated brown soil. 通過室內(nèi)等溫培養(yǎng)試驗(yàn)，研究了施用富里酸和胡敏酸對耕地棕壤鉀素釋放和固定作用的影響。
