Meixiangzhan 2 is a high-quality Simiao rice variety with the largest planting area in Guangdong Province. It has the characteristics of high quality, strong regeneration ability and wide adaptability. This paper summarized the planting performance of Meixiangzhan 2 as machine-harvested low stubble ratooning rice in northern Guangdong from 2018 to 2021. In ratooning season, Meixiangzhan 2 had a growth period of 84~89 days, and the effective accumulated temperature from harvest of the early season to the heading stage of the ratooning season was 893 ℃~1 092 ℃. The grain yield of ratoon rice was 293.5~343.0 kg/667 m², amounting to 69.1%~74.6% of that of early season. In 2021, the total cost investment and economic benefit of early rice-ratooning rice mode was 1 974.5 yuan/667 m² and 824.3 yuan/667 m², respectively. Compared with the single-season rice, the yield of ratooning rice mode increased 328.0 kg/667 m², and the economic benefit increased 740.3 yuan/667 m², respectively. Compared with the double cropping rice, early rice-ratooning rice mode decreased the total grain yield by 57.0 kg/667 m², but saved the total cost investment by 582.5 yuan/667 m², and increased the economic benefit by 377.3 yuan/667 m². This paper also summarized the key cultivation techniques of Meixiangzhan 2 as machine-harvested low stubble ratooning rice, in order to provide reference for high-yield cultivation of mechanically harvested ratooning rice in South China.
