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.

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 ...
