安徽省粳稻生产现状及籼改粳发展潜力分析

Production Situation and Development Potential of Japonica Rice in Anhui Province

通过对安徽省近3年粳稻生产情况进行调研,分析了安徽省粳稻生产现状及存在的主要问题,明确了制约安徽省粳稻发展的主要因素,以推进"籼改粳"工作进程,提升安徽省稻米产业的竞争力。安徽省粳稻种植主要分布在合肥、安庆、六安、芜湖、蚌埠、滁州等地;粳稻生产以直播为主,机插为辅;所种植的粳稻品种以外引为主,占77.57%,本省自主选育品种仅占22.43%;近3年粳稻平均单产为7.51 t/hm^2。提出应以沿淮、沿江一带以及江淮东南部为重点区域,以发展中粳和单季晚粳为主体的建议。最后,提出了安徽省加快发展粳稻生产的目标和对策。

In order to enhance the competitiveness of Anhui rice industry, the investigation on japonica rice production status in recent three years was carried out in Anhui province, to clarify the situation of japonica rice production and restrict development factors. Anhui japonica rice cultivation is mainly distributed in Hefei, Anqing, Liuan, Wuhu, Bengbu and Chuzhou cities. Planting method for japonica rice production was mainly direct-seeding, supplemented by machine transplanting. Moreover, japonica rice varieties used in Anhui province were primarily introduced from outside for nearly accounted for 77.6%, and only 22.4% come from the Anhui province. The average grain yield of japonica rice in recent three years was 7.51 t/hm2. It is suggested that the main areas should be the main areas along the Huaihe River, the Yangtze River, southeast of Jianghuai area, and the planting varieties should be focused on middle-season japonica rice and single late-season japonica flee. Finally, the aim and countermeasures of accelerating the development of japonica rice production in Anhui province were put forward.
