Abstract

Abstract: ： In order to explore the appropriate stubble height of ratooning rice in Tianmen city, Hubei province, taking the Fengliangyouxiang No.1 as experimental materials, the effects of different stubble height on the growth and development dynamics, yield of ratooning rice were studied. The results showed that, as the stubble height of Fengliangyouxiang No.1 increased at the range of 15~45 cm, the growth period shortened, the plant height increased, the ratooning tillers increased, panicle length and grain number per panicle all decreased, effective panicles, and ratooning rate increased, the stubble height of 45 cm showed the highest yield, was 4 570.45 kg/hm². Comprehensive analysis of the growth period, ratooning rate and yield,the highest stubble height should be reserved for ratooning cultivation of Fengliangyouxiang No.1.

Key words: ratooning rice, Fengliangyouxiang No.1, stubble height, growth and development dynamics, yield
