摘  要：
采用田间小区试验,在典型的镉污染稻区长沙县北山镇、湘潭县梅林桥镇开展了重金属修复剂"植宝素有机水溶肥料"、"植宝素腐植酸水溶肥料"的田间应用效果试验。结果表明,北山点施用"植宝素有机水溶肥料"处理(ZHW)和"植宝素腐植酸水溶肥料"处理(ZHF)分别比常规施肥处理水稻增产7.77%(P<0.05)和10.22%(P<0.05);湘潭点ZHW和ZHF处理分别比常规施肥处理水稻增产8.60%(P<0.05)和8.59%(P<0.05)。两试验点有机水溶肥的稻米镉含量皆达到食品安全国家标准,北山点ZHW和ZHF处理的稻米镉含量分别比常规施肥下降48.15%(P<0.05)和37.04%(P<0.05);湘潭点则分别下降33.33%(P<0.05)和52.38%(P<0.05),并对水稻吸收积累其他重金属也有一定的抑制效果。

摘  要：
A field plot experiment was conducted to evaluate the application effect of "Zhibaosu organic water soluble fertilizer"(ZHW) and "Zhibaosu humic acid water soluble fertilizer"(ZHF) in two typical cadmium polluted paddy areas, Beishan town in Changsha county and Meilinqiao town in Xiangtan county. The results showed that compared with the rice yield of conventional fertilization(CK),those of the treatments applying ZHW and ZHF increased by 7.77%(P <0.05) and 10.22%(P <0.05) at Beishan respectively, and by 8.60%(P <0.05) and 8.59%(P <0.05) at Meilinqiao respectively. The cadmium content of rice at both two places reached the National Standards for Food Safety, and those of the treatments applying ZHW and ZHF reduced by 48.15%(P <0.05) and 37.04%(P <0.05) at Beishan respectively, and by 33.33%(P <0.05) and 52.38%(P <0.05) at Meilinqiao respectively. The application of ZHW and ZHF could also reduce the content of other heavy metals of rice.
