determination of phosphorus fixation capacity
磷素固定量的测定
The fixation rate of phosphorus fertilizer in high P lever soil was distinctly lower than that in low P lever soil.
高磷土壤上,磷肥固定率显著低于低磷土壤。
The residual effect and the fixation and transformation principles, the efficiency of water-soluble phosphorus fertilizer during experiment period on a calcarious soil are studied from 1982 to 1989.The economic efficiency of different distributions is also evaluated.
对河北省低磷石灰性土壤磷肥后效以及试验周期中水溶性磷肥的固定转化规律及其有效性进行了研究,并对磷肥不同分配方式的经济效果做了评价。
