| 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 show that the selenium level of the former sample(total selenium is 0.075×10-6;aqueous and exchangeable selenium is 0.020×10-6) is higher than that of the latter(total selenium is 0.045×10-6;aqueous and exchangeable selenium is 0.010×10-6). |
