俄罗斯硅肥对水稻的降镉增产效果研究

Study on Effect of Cadmium-decreasing and Yield-increasing of Russian Silicon Fertilizer on Rice

以黄华占、美香占2号和湘晚籼12号为材料,研究了施硅量对其产量、产量构成因素以及稻米镉含量的影响。结果表明:黄华占、美香占2号和湘晚籼12号的增产原因是施用硅肥提高了实粒数、总粒数和结实率;湘晚籼12号在施硅量为150 kg/hm2时增产效果明显,稻米降镉量大可获得较高的经济效益。

Taking Huanghuazhan,Meixiangzhan 2,Xiangwanxian 12 as the test material,the effect of silicon amount on rice yield,yield components and cadmium content in rice grain was studied.The results showed that the reason of the yield increasing of Huanghuazhan,Meixiangzhan 2,Xiangwanxian 12 was due to of the improving of real grain number,total grain number and seed setting rate by applying silicon fertilizer.When Silicon applying amount was 150 kg/hm2,the effect of increasing production of Xiangwanxian 12 was obvious,cadmium content in rice grain declined obviously,economic benefit was high.
