针对目前市场上的硒肥种类繁多、肥效不一现象及其使用安全性,采用田间试验、室内分析和生物统计的方法,在宁夏引黄灌区开展了不同叶面硒肥对水稻各组织器官硒含量影响的试验。试验结果表明:喷施不同叶面硒肥较清水对照在水稻上富硒效果好,且富硒效果植株>籽粒,参照国家和宁夏稻谷富硒标准,喷施螯合硒叶面肥的水稻籽粒硒含量安全性较高;清水对照的水稻籽粒就能达到富硒。因此,提倡自然富硒,在外源补硒中建议叶面喷施螯合硒叶面肥。
In view of the wide variety of selenium fertilizer on the market, the phenomenon of different fertilizer efficiency and the safety of its use, field experiments, laboratory analysis and biological statistics were conducted to study the effect of different foliar selenium fertilizers on selenium Effect of content test. The results showed that the effect of spraying different foliar selenium fertilizer on the paddy rice was better than that of the control on the selenium fertilizers, and the selenium-enriched plants> kernels, the reference country and Ningxia paddy selenium standard, Selenium content higher safety; water control rice grain can achieve selenium. Therefore, to promote natural selenium, foliar application of selenium in the external selenium fertilizer selenium foliar fertilizer.
