Ecological Adaptability of Early Indica and Early Japonica Rice in Hunan
摘要
Abstract
In order to observe the ecological adaptabitity of early indica varieties and japonica rice varieties in Pingtou Vil-lage,Liuyang City in 201 3. The results showed that yield was between 5.37 to 8.25 t/hm2. The yield of Zhongzao 39 was the highest,up to 8.25 t/hm2.And the lowest was Longjing 21 ,5.37 t/hm2. The growth period of test varieties was be-tween 1 07 and 1 1 3 days,and all tested warieties matured before 1 6th,July.All varieties are suitable for early season culti-vation in Changsha area,Hunan province,the yield of early indica rice varieties was higher than that of Japonica rice vari-eties. According to the results,early indica rice was more suitable in Hunan area.关键词
