摘要

以新疆某地污水库周边农田土为供试土壤

采用CaCl2、EDTA、HOAC、柠檬酸四种浸提剂提取土壤中钛的有效态

并用Tessier和BCR两种连续提取法分析钛在土壤中的形态分布.结果显示:Tessier法和BCR法分步提取的钛的各个形态与四种浸提剂提取的有效钛量显著相关

与土壤中Ti的全量显著相关.两种连续提取法所得到各形态Ti含量都随着外源Ti浓度增加而增加

Ti在土壤中主要以稳定的残渣态存在

有效态含量较低

与单独提取法结果一致.Tessier法和BCR法都适用于该地区土壤中Ti的各形态分步提取.通过盆栽紫花苜蓿实验初步考察了土壤中Ti的各形态对苜蓿生理特性的影响.

Abstract

Took the surrounding farmlands of a certain pollution of the library in Xinjiang as experimental soils

adopted Ca Cl2

EDTA

HOAc and citric acid as extractants to extract available state from the Ti in soils

and used Tessier and BCR continuous extraction methods to analyze the morphological distribution of Ti in soils. The results showed that the each state of Ti extracted by Tessier and BCR methods were significantly correlated with the amount of effective Ti extracted from the four kinds of extractants

and were positively correlated with the total amount of Ti in soils. Each state of Ti content extracted by the two continuous extraction methods increased with the increase of exogenous Ti concentration

and the content of Ti in soils was mainly in the state of stable residual

and the available state was low

which was consistent with the results of the single extraction method. Both Tessier and BCR methods are suitable for extracting stepwise each state of Ti from the soils of the area. A preliminary investigation about the effects of each state of Ti on the physiological property of alfalfa was based on the potting alfalfa experiment.
