Regulation Effects of Different Types of Foliar Regulators on Heavy Metal Content in Rice
摘要
Abstract
The main rice variety T xiangyou557 in Huishui County,Guizhou Province was selected as the experimental material.The effects of different types of foliar inhibitors on cadmium reduction and heavy metal mercury,arsenic,lead,chromium,selenium and germanium in rice were evaluated by u-sing foliar regulation technology and conducting plot experiments and large area experiments.The re-sults showed that the cadmium content of rice decreased in different degrees under the treatment of five kinds of leaf regulators.In the plot experiment,the cadmium content of rice was sorted from small to large with Chuge,Cd Wuyou,Meixinlong,Jiangcading,Tianxiang,control.The order of cadmium content in rice from small to large was as follows that Cd Wuyou,Jiangcading,Tianxiang,ck,Chuge,Meixinlong.The highest rate of cadmium reduction was Cd Wuyou,reaching 55.64%,followed by Jiangcading and Tianxiang,with cadmium reduction rates of 54.46%and 10.20%,re-spectively.The contents of mercury,arsenic,lead,chromium,selenium and germanium in rice did not exceed the national standard limits.In the large-scale experiment,it was found that the selenium content of rice under the three treatments of Jiangcading,Chuge and Tianxiang reached the selenium-rich standard.The highest content measure was spraying Jiangcading,with a content of 0.058 8 mg/kg.Germanium was not detected in all treatments.According to the comprehensive evaluation,it was concluded that spraying three kinds of leaf inhibitors such as jiangcadingling,cadmium worry-free and astronomical phenomena can reduce the cadmium content in rice for the main cultivated rice variety(T xiangyou557)in central Guizhou.It was suggested that three kinds of leaf inhibitors such as jiangcad-ingling,cadmium worry-free and astronomical phenomena should be applied in paddy fields with high background of heavy metals.关键词
