摘要

为确定螯合剂活化土壤磷素的最佳浓度和最优浸提时间，参考水肥一体化技术，在室内浸提条件下，研究了不同浓度（0，0.05，0.1，0.25，0.5，1.0 g/L）乙二胺四乙酸（EDTA）和柠檬酸螯合剂（pH=4）在不同浸提时间（1，12，24，48，72 h）下对粮田、菜田土壤和有效磷被钝化后菜田土壤中磷素提取效果。结果表明：EDTA和柠檬酸在粮田土壤上对磷素提取中最佳条件为螯合剂浓度0.05 g/L，浸提时间12 h。EDTA和柠檬酸在菜田土壤、明矾钝化和混合钝化（明矾∶白云石为1∶1）菜田土壤上提取磷素的最佳条件为螯合剂浓度0.5 g/L，浸提时间12 h；而在白云石钝化土壤中则为螯合剂浓度0.5 g/L，浸提时间1 h。总体来看，柠檬酸的活化提取磷素效果优于EDTA，尤其是在采用明矾和白云石钝化的土壤上。

Abstract

In this study

the extracting experiment was conducted to investigate the effect of EDTA and citric acid (pH=4) on P mobilizationin in the grain field soil

greenhouse soil and P-stabilized greenhouse soils under different concentrations (0

0.05

0.1

0.25

0.5

1.0 g/L) and different extraction times (1

72 h)

to make sure the optimal concentration and extraction time of chelating agent to extracts P from soils. The results indicated that the optimal concentration and extraction time were 0.05 g/L and 12 h for EDTA and citric acid in grain field soil. The optimal concentration and extraction time were 0.5 g/L and 12 h for EDTA and citric acid in green house soil

alum-stabilized soil and mixed-stabilized (alum:dolomite was 1:1) soil. The optimal concentration and extraction time were 0.5 g/L and 1 h for EDTA and citric acid in dolomite-stabilized soil. Generally

the effect of citric acid was better than that of EDTA

especially in alum and dolomite stabilized soil.
