摘要/Abstract

摘要：用DAN荧光法测定硒含量的研究表明，施加硒肥的糙米中总硒含量（0.07×10^-6)及水溶态与可交换态硒的含量（0.020×10^-6)，明显高于未施加硒肥的糙米中总硒含量（0.045×10^-6）及水溶态与可交换态硒的含量（0.010×10^-6）.这说明对于缺硒地区的水稻培育，施加硒肥是一种有效的措施.

Abstract: The total selenium and aqueous and exchangeable selenium was fluorometrically determined in two samples of crude rice;one had been fertilized with selenium and the other had not.The results showed that the selenium level of the former sample（total selenium is 0.075×10^-6；aqueous and exchangeable selenium is 0.020×10^-6 was higher than that of the latter(total selenium is 0.045×10^-6； aqueous and exchangeable selenium is 0.010×10^-6.
