Study on using methods and application effects of rice reducing-cadmium agent JGLY-2

In order to research the using methods and application effects of rice reducing-cadmium agent， the germination rate，seedling quality and contents of Cd，Zn，Mn and Fe of rice were determined by means of germination experiments of seed-coating，seed-soaking and foliar spray with rice reducing-cadmium agent JGLY-2. Results showed that the best usages of seed coating，seed soaking and foliar spray of JGLY-2 were as follows：coating ratio 1∶20，seed soaking ratio 1∶20 and foliar spray 5 g. Compared with untreated controls，the contents of Cd and Mn in rice seedling treated with the 3 methods using JGLY-2 decreased by 30.30%-49.57% and 7.46%-19.18%， respectively. The dry weight and Zn content of rice seedling increased by 0.62%-8.62% and 0.20%-15.94%， respectively. This rice reducing-cadmium agent could significantly reduce cadmium content in seedling and prevent harm of rice under cadmium stress，it was an effective medicament for reducing cadmium pollution of rice.
