育秧方式对“株两优124”生育特性及产量的影响

Effects of Different Seedling Raising Methods on Growth Characteristics and Yield of Zhuliangyou 124

2010年,以杂交早稻"株两优124"为供试品种,在湘北洞庭湖区沅江市进行旱地育秧,小苗带土育秧和湿润育秧的田间栽培试验,研究3种育种方式对杂交早稻的生育特性、产量性状以及产量的影响。结果表明:与传统的湿润育秧比较,旱地育秧、小苗带土育秧在提早播种的条件下,可使"株两优124"成熟期提早3～5 d,产量增加13%～20%。

The early hybrid rice Zhuliangyou 124 was used as experimental variety to conduct field cultivation experiments with different seedling raising methods, such as raising seedlings on dry-land, raising seedlings with soil and raising seedlings with moisture. The influences of the three seedling raising methods on growth characteristics, yield characteristics and yield of early hybrid rice were also studied. The results showed that in comparison with traditional moisture raising seedling, the methods of raising seedlings on dry-land and raising seedlings with soil can advance mature period of Zhuliaugyou124 by 3-5 d, and increase yield of Zhuliangyou 124 by 13%-20%.
