再生稻的研究利用概况与前景

The Study and Utilization of Ratooning Rice and Its Prospects

再生稻是一种费省效宏的稻作形式，近年在四川、湖北、广东、福建等省发展较快。四川省１９８６～１９８９年累积发展再生稻面积１４５９．１３万亩，总产１４亿公斤。杂交中稻蓄留再生稻已成为一种新的耕作制，为水稻生产开辟了一条新途径，在我国南方稻区有较大的增产潜力。本文还分析了国内再生稻研究概况及国外再生稻研究与应用的发展趋势。

Ratooning rice cultivation is characterized by less investments and more returns. In recent years it develops rapidly in provinces Sichuan, Hubei, Guangdong and Fujian. In 1986-1989 the area of ratooning rice in Sichuan amounted to more than 14.59 million mu, and the rice yield totalled up to 1.40 milliard kg.Use of medium hybrid rice to grow ratooning rice bas become a new cropping pattern which has good prospects in the south of China. In the paper the present situation and the trend of ratooning rice researches in china and other countries are also described.
