摘要
为了探究镉污染下水稻的安全生产方式,采用小区试验,比较了 50 个水稻品种在湖南省镉轻度污染地区的糙米镉积累情况,并研究了喷施植物酵素对不同品种糙米镉积累的影响.结果表明:不同品种水稻对镉的吸收存在显著差异,在考察的 50 个水稻品种中,泰优 390、隆香优 310、隆两优 1988 等品种检测出的镉含量显著低于其他品种,可作为镉轻度污染区域水稻安全生产的应急品种;喷施生物酵素的试验结果表明,生物酵素对不同品种稻米镉累积的影响存在显著差异,施喷酵素可以使某些水稻品种中镉含量降低至国家安全限值以下.
Abstract
To explore the safe rice production under cadmium contamination,this study examined the cadmium accumulation in the brown rice of 50 cultivars grown in the areas with light cadmium contamination in Hunan Province and investigated the effects of spraying plant-derived enzymes on cadmium accumulation in the brown rice of different cultivars.The results showed that the cadmium uptake by rice varied significantly among different cultivars.Among the 50 rice cultivars studied,'Taiyou 390','Longxiangyou 310',and'Longliangyou 1988'had significantly lower cadmium content than other rice cultivars and could serve as emergency cultivars for safe rice production in the areas with light cadmium contamination.Spraying bioenzymes exerted significantly different effects on the cadmium accumulation in different rice cultivars.The cadmium content in some rice cultivars could be reduced to the level below the national safety limit by reasonable application of enzymes.
