宁夏引黄灌区水稻硒肥肥效试验研究

Study on the Effects of Selenium Fertilizer in Rice Plants in Ningxia Yellow River Irrigation Area

采用田间管理、室内分析与生物统计相结合的方法,在宁夏引黄灌区进行水稻硒肥肥效试验,试验结果表明:叶面喷施硒肥效果优于基施,水稻植株硒含量大于籽粒硒含量,在水稻孕穗期和灌浆期叶面喷施硒肥,能有效提高水稻硒含量。

The field management, lab analysis and biological statistic were applied to study the effects of selenium fertilizer in rice plants in Ningxia Yellow River irrigation area. The results of multi-location experiment showed that the effects of selenium fertilizer in foliar were better than that in base application. The selenium content of rice plant was larger than that of grain. The selenium fertilizer in foliar during the booting stage and filling stage could effectively improve the selenium content.
