【摘要】 通过叶面喷施顺天降镉剂,分别采用田间小区试验和大田对比试验,研究其对降低稻米中镉含量的效果。试验结果表明,通过叶面喷施顺天降镉剂的水稻精米中镉含量明显降低,小区对比试验早稻降低27.3%,晚稻降低40.3%;大田示范早稻春优84和晚稻五优华占分别下降12.1%和18.6%。通过对晚稻小区的测产,喷施顺天降镉剂还可以小幅度增加水稻产量,增幅为7.1%。更多还原

【Abstract】 This paper studied the effect of Shuntian cadmium reducing agent on decrease cadmium content in rice by spraying it on the surface of the rice through field test and oda test. The results showed that the cadmium content in milled rice decreased obviously by using Shuntian cadmium reducing agent, the early rice decreased 27.3%, while the late rice decreased 40.3% in oda test. The demonstration early rice Chunyou 84 and late rice Wuyouhuazhan decreased 12.1% and 18.6% respectively in field test. Based on the yield test of late rice in oda test, spraying Shuntian cadmium reducing agent can also increase the yield about 7.1%.更多还原
