Effect of Foliar Application of Na2SeO3 on the Yield and Quality of Ratooning Rice
摘要
Abstract
[Objective]The objective of this study is to reveal the effects of foliar application of selenium on the yield and quality of ratooning rice, which will lay a theoretical basis for high quality and high yield cultivation of ratooning rice.[ Method ] The experiment was carried out at Shakou Town, Honghu City, Hubei Province in 2016 with Fengliangyouxiang1 as the experimental material and Na2SeO3 as selenium source. Foliar spray of Na2SeO3 was conducted in the initial heading stage, full heading stage, and initial heading date+full heading date at 0g/hm2, 5.625g/hm2, and 11.250g/hm2.[Result]The foliar application of Na2SeO3 increased the yield of ratooning rice with no significant difference between the control and the treatment with Na2SeO3 spraying in initial heading stage. Na2SeO3 spray during the full heading date at 5.625g/hm2 and 11.250g/hm2 increased the rationing rice yield by 2.59% and 5.50%, respectively, foliar spraying of 5.625g/hm2 and 11.250g/hm2 Na2SeO3 duning initial heading date and full heading date increased the yield by 4.83% and 7.08%, respectively. The suitable dosage was 11.250g/hm2 for initial heading date and heading date, with the highest yield of 5533.33kg/hm2. The foliar application of Na2SeO3 increased yield by increasing grain number, filled grain number and seed setting rate. The foliar application of Na2SeO3 can improve the quality of ratooning rice. The suitable dosage was 11.250g/hm2 for full heading date. The spraying of selenium fertilizer improved quality by increasing whole polished rice rate, and reduced the chalky grain rate. At the full heading date, under foliar spraying of 11.250g/hm2 Na2SeO3 the whole polished rice rate was the highest(61.37%) and the chalky grain rate was the lowest (9.37%).[Conclusion]The results showed that the application of Na2SeO3 could improve the yield and quality of ratooning rice. The yield of ratooning rice peaked during initial heading date and full heading date at 11.250g/hm2 Na2SeO3; ratooning rice had the best quality at 11.250g/hm2 Na2SeO3 in the full heading date.关键词
