Effects of Selenium Powder on the Selenium Content of the Early Rice Lingliangyou 211

In order to find out the effects of selenium powder with concentration(0,10,20,30,40,50 kg/667m2) on early rice Ling-liangyou 211, selenium powder(83 mg/kg) produced in Enshi Hubei was used in the land of Fengcheng Jiangxi with selenium content of 0.430 6 mg/kg. The results showed that selenium powder increased selenium content in grain and stalk.The selenium content in grain with selenium powder of 10~50 kg/667 m2 was 0.113 4~0.255 0 mg/kg. Compared with selenium content of 0.108 0 mg/kg,that in grain increased 5.00%~136.11%. The selenium content of grain with selenium powder of40 kg/667 m2 and 50 kg/667 m2 are higher than that with selenium powder in other concentrations. Selenium powder increased the selenium content in stalk. The selenium content in stalk with selenium powder of 10~50 kg/667 m2 was 0.312 6~0.361 2mg/kg. Compared with 0.291 9 mg/kg, the selenium content increased 7.09%~23.74%. The selenium content in stalk with selenium powder of 50 kg/667 m2 was higher than that with selenium powder in other concentrations. The selenium content in grain and stalk was positively correlated with the amount of selenium powder used in each square meters of the same land.The selenium content in stalk was higher than that in the grain. The selenium content in stalk with different amount of Selenium powder was 41.64%~175.66% higher than that in grain.
