The rice varieties Tonghe-833,Tonghe-885 and Tonghe-899 were used as research objects,and the use of selenium-rich organic fertilizer was compared with clear water by spraying on leaves.By comparing and analyzing the chlorophyll content,yield traits,rice quality and trace element content including selenium in each treatment,we can understand the influence of selenium-enriched organic fertilizer on rice production,and further optimize and clarify the high-yield and high-quality cultivation techniques of"selenium-enriched rice".The results showed that spraying selenium-enriched organic fertilizer on leaves could improve the yield and quality of rice,and the rice produced met the standard of selenium-enriched rice,which had a good demonstration application effect.
