西藏林芝市农田土壤锌资源可利用性评价
Evaluation on Availability of Zinc Resources in Farmland Soil in Linzhi City,Xizang
摘要
Abstract
Zinc is an essential trace element for animals,plants and humans,which is of great significance for promoting growth and development,regulating immune function and maintaining vital signs.In order to understand the distribution and agricultural utilization potential of zinc in farmland soil in Linzhi City,Xizang,samples of farmland soil and corresponding cultivated crops were collected from Gongbujiangda County,Milin City,Bomi County,Zayu County and Bayi District to detect total zinc content.The results showed that the total zinc content of farmland soil in the study area was high,and 45.5%of farmland soil reached the zinc rich level.In the edible part of the crop,30%of the samples met the zinc-rich standard.There was no significant correlation between the distribution of zinc-rich crops and the distribution of zinc-rich soil.Based on the soil pollution risk control standard of agricultural land as the evaluation basis,the zinc content of farmland soil layer in the study area did not exceed the screening value of agricultural land soil pollution risk,and the environmental quality was good.The evaluation results of single factor pollution index showed that the zinc content of farmland soil in the study area was pollution-free.Understanding the distribution and resource availability of zinc in farmland soil in Linzhi City,Xizang is of positive significance for rational utilization of zinc-rich soil resources and development of zinc-rich industry.关键词
