| 为了探明水稻降镉剂的施用方法及应用效果，通过包衣、浸种、叶喷3 种施用方式的发芽试
验，测定了降镉剂JGLY-2 处理种子或秧苗后水稻的发芽率、苗素质及苗体镉、锌、锰、铁含量。结果显示：
降镉剂3 种施用方式的最佳用量分别为包衣比1∶20、浸种比1∶20、叶喷5 g。与对照相比，用降镉剂3 种
施用方式处理后，秧苗镉、锰含量分别降低30.30%~49.57%、7.46%~19.18%；秧苗干重、锌含量分别提高
0.62%~8.62%、0.20%~15.94%。表明水稻降镉剂能显著降低水稻镉含量，减轻镉胁迫对水稻的危害，是一种
降低水稻镉污染的有效药剂。 |
| 英文摘要: |
| 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. |
