摘要
选取红田土、黄泥土、潮沙土三种水稻土对有机磷和无机磷吸附特征进行研究,三种水稻土对两种形态磷吸附存在相同规律,吸附量表现为红田土>黄泥土>潮沙土,同种土壤有机磷的吸附量小于无机磷,对三种水稻土进行磷吸附动力学研究,表现为无论是有机磷还是无机磷,均为吸附前期速度较快,后期逐渐变慢。
Three kinds of paddy soils(red soil、yellow soil、tidal sandy soil)were selected to study the adsorption characteristics of organic and inorganic phosphorus.The adsorption laws of phosphorus in the three kinds of paddy soils were similar,which were red soil>yellow soil>tidal sandy soil;The adsorption of organic phosphorus in organic fertilizer is affected by the medium,and the adsorption capacity of phosphorus is weakened.The adsorption kinetics of three paddy soils showed that both organic phosphorus and inorganic phosphorus were fast in the first and slow in the second.
