播期和秧龄对杂交稻‘九优六号’产量的影响
Effects of Different Sowing Date and Seedling Age on Yield of Hybrid Rice ‘Jiuyou-6’
摘要
Abstract
In order to determinate the optimal sowing date and seedling age of hybrid rice Jiuyou-6,experiment about sowing date and seedling age were conducted in Liuyang city of Hunan province in 2014.The results indicated that the yields were increased firstly and then decreased with the delay of sowing date,and the yield of S3 was the highest.The total growth period was increased with the increase of seedling age,and the average total growth period of treatment seedling age 40 d was 136 d,which is the longest.The actual yield was decreased with the increase of seedling age,and the average yield was 9.30 t/hm2.The yield of treatment seedling age 20 d was the highest,and that of treatment 40 d was the lowest.Therefore,the optimal sowing date is from April to the end of May with seedling age 20 d.关键词
