摘　　要：以壳聚糖和螺旋藻粉为原料,采用滴加成球的方法制备一种新型的重金属吸附剂——壳聚糖交联螺旋藻小球。研究施用壳聚糖交联螺旋藻小球对水稻镉吸收的影响,研究壳聚糖交联螺旋藻小球在土壤中的不同施加量(2%,4%)对稻米籽粒中镉含量的影响。结果表明:施用壳聚糖交联螺旋藻小球能够显著降低稻米籽粒中镉的含量,但是在土壤中施加量为4%也未能达到食品安全国家标准,可能是因为壳聚糖交联螺旋藻小球的施加量不足。In this study,we wish to introduce a new heavy metal sorbent,i.e.,chitosan cross-linked spirulina pellets(CCSP),which was made from the chitosan and spirulina powder using drop addition technique.In order to clarify the effects of CCSP application on cadmium uptake in rice,the effects of different CCSP application rates(2%,4%)on soil.Cadmium content in rice grain was studied.The results showed that:the application of CCSP significantly reduce the content of cadmium in rice grains,but higher than the national food safety standard.
