硒浸种与叶面喷硒对水稻吸收转运镉的影响
Effects of Uptake and Transport of Cadmium in Rice(Oryza sativa L.)by Soaking Seeds and Foliar Spraying with Selenium Fertilizers
摘要
Abstract
In this study,the effect of selenium on the uptake and transport of cadmium in rice were evaluated by exogenous application of selenium(selenium-soaked seeds,foliar selenium spraying and selenium-soaked seeds combined with foliar selenium spraying treatments)using rice(T-Young 109 and Shenliangyou 5814)as experimental subjects.The results showed that selenium-soaked seeds combined with foliar spraying of selenium treatment had the best effect on reducing cadmium content in rice plants,and the selenium-soaked seeds combined with foliar spraying of selenium treatment significantly reduced cadmium content in roots,stems,leaves and spikes of T-Young 109 rice at the spike stage and milky ripening stage(P＜0.05),which were reduced by 26.64％,25.81％,6.25％,and 20.00％,respectively,and 22.05％,17.23％,27.42％and 18.95％respectively,when compared with the control group.Selenium-impregnated seeds combined with foliar spraying of selenium treatment significantly reduced cadmium content in roots,stems,leaves and spikes of Shenliangyou 5814 rice by 9.30％,29.41％,35.39％and 19.83％,respectively,as compared with the control,and selenium-impregnated seeds combined with foliar spraying of selenium both significantly reduced the cadmium enrichment coefficients of the roots,stems,leaves and spikes of the two types of rice(P＜0.05).Exogenous selenium application could reduce the cadmium content of rice grains and increase the weight of rice spikes,among which the selenium-soaked seeds combined with foliar spraying of selenium had the best effect.Under the same selenium fertiliser treatment,the effect of reducing the cadmium content in brown rice and increasing the yield of kernel weight of T-Young 109 rice was better than that of Shenliangyou 5814 rice.关键词
