不同播种期对宜优673产量及稻米品质的影响
Effect of Sowing Date on Yield and Rice Quality of Yiyou 673
摘要
Abstract
Interval sowing date experiment was executed with Yiyou 673 as testing material to explore the variation of yield and rice quality under different sowing dates. The results showed that the yield was firstly ascended and then declined gradually with the delayed sowing dates of rice. The yield of Yiyou 673 was the highest when it was sowed on May 20th. But when it was sowed on June 20th, the yield was the lowest. Head milled rice rate, translucent endosperm, amylase content, and scores of physicochemical index were increased with the delayed sowing date and the reduced average temperature during filling stage. At the same time, chalky rice rate and chalkness rate were reduced. So, on the basis of the full heading time, it is beneficial to improve the quality of rice with suitably delayed sowing date of Yiyou 673.关键词
