为观察早籼与早粳稻品种在湖南的生态适应性，2013年早季在湖南浏阳市永安镇进行了比较研究。结果表明，试验品种产量在5.37～8.25 t／hm2之间，中早39产量最高，达8.25 t／hm2，产量最低的是龙粳21，为5.37 t／hm2；品种全生育期在107～113 d之间，均在7月16日之前成熟。可见试验品种均能在湖南长沙地区做早稻栽培，籼稻品种比粳稻品种产量高，早籼稻更适合在湖南地区作早稻栽培。

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.
