Treatments of BSM were tested as 0g/hm2, 200g/hm2, 300g/hm2, 400g/hm2 and 600g/hm2 in quadruplications, respectively, according to the commercial recommendations of 200g/hm2 to 400g/hm2. Cadmium was applied as 5 mg/L with cadmium chloride.

• 本文利用109Cd2+示踪技术,以水稻为指示植物,根据苄嘧磺隆的商业推荐施用量200g/hm2至600g/hm2,研究了苄嘧磺隆施用量分别为0g/hm2,200g/hm2,300g/hm2,400g/hm2和600g/hm2时,对重金属元素Cd的生物有效性影响。
