摘要: 采用黄冈市农业科学院自主选育的常规早稻新品种冈早籼11号、冈早籼13号以及芯两优9011作为研究对象,进行双季稻双机直播筛选。结果表明,冈早籼11号生育期合适,生产安全性高,株高适宜,且产量高,肥料利用率高,适合作为双季稻双机直播品种。对冈早籼11号开展不同播种量试验,冈早籼11号早稻季按150 kg/hm2播种量+晚稻季按180 kg/hm2播种量,两季经济效益最高。

Abstract: Using conventional early rice varieties Gangzaoxian 11, Gangzaoxian 13 and Xinliangyou 9011 bred by Huanggang Academy of Agricultural Sciences as research objects, the screening for rice varieties in driect-seeded, double-season rice system was conducted. The results showed that, Gangzaoxian 11 has a suitable growth period, high production safety, suitable plant height, high yield, and high fertilizer utilization. It is suitable for rice varieties in driect-seeded,double-season rice system. This experiment carried out a different seeding rate experiment on Gangzaoxian 11. The results showed that, the early rice season of Gangzaoxian 11 at 150 kg/hm2 seeding rate+ late rice season at 180 kg/hm2 seeding rate, the two seasons have the highest economic benefits.

Key words: rice, driect-seeded, double-season, variety, seeding quantity
