Abstract:

This study was conducted to investigate the effects of different doses of selenium fertilizer applied at booting stage on the yield and rice quality of japonica rice varieties Nanjing 9108 and Wankennuo 2. The results showed that selenium fertilizer sprayed at booting stage could significantly (p<0.05) increase the content of selenium in rice,and had positive effects on the yield and quality of rice.Compared with the control,the yield of these two rice varieties increased after spraying 30 and 60 mL·hm-2 of selenium fertilizer,and the yield of Nanjing 9108 and Wankennuo 2 increased by 2.25% and 4.09%,respectively, after spraying 60 mL·hm-2 of selenium fertilizer. In addition,the application of selenium fertilizer could effectively improve the grain filling rate,SPAD value of flag leaf,taste value and head rice rate,and reduce chalky grain rate and chalkiness degree,and improve the processing quality and appearance quality of rice. The results provided theoretical basis for rational utilization of selenium fertilizer and improvement of selenium nutrition level of rice.
