Research Progress on Safe Utilization Technology of Heavy Metal Contaminated Farmland
Currently,heavy metal pollution in arable land is still widespread and severe in China.The envi-ronmental quality of cultivated land is an important guarantee for ensuring the safe production of agricultural products.With the rapid development of urban industrialization and agricultural intensification in China,heav-y metal pollution from various sources enters cultivated land through methods such as dust reduction,fertiliza-tion,and irrigation,resulting in reduced crop yields and endangering human health.Based on the above is-sues,this article summarizes the research and application of various agronomic regulation technologies(lime regulation,optimized fertilization,variety screening,leaf barrier,etc.),soil improvement technologies(pas-sivators and conditioners),and biological technologies(microorganisms and plants)for the safe utilization of heavy metal polluted farmland.And prospects were made for its safe utilization in heavy metal polluted farm-land.
