Abstract: |
To…explore…the…impact…of…quick…lime…on…cadmium…enrichment…capability…of…rice, and…to…screen…practical…
agronomic…measures…which…could…reduce…the…accumulation…of…cadmium, six…rice…varieties…were…selected…in…a…field…trial…
in…central…China.…The…results…showed…that, in…addition…to…Xiangzaoxian…45, the…yield…of…other…varieties…had…no…significant…
decrease…after…application…of…quick…lime.…Application…of…quick…lime…could…significantly…reduce…the…cadmium…content…in…
rice.…Zhongjiazao…17…had…the…lowest…content…of…cadmium, and…Lingliangyou…674…had…the…highest…content…of…cadmium, the…
difference…was…significant.…The…pH…increased…in…the…soil…with…quick…lime, by…8.90%, but…the…content…of…cadmium…did…not…
change…significantly.…The…content…of…cadmium…had…no…significant…difference…in…the…six…rice…varieties. |
