Abstract

Abstract

Different nitrogen application ratio in the second crop of ratoon rice for good quality cultivar Jiafuzhan were studied in order to increase grain yield at Jianyang City of Fujian Province.The results showed that grain yield in the second crop exhibited a parabolic curve relationship with nitrogen application ratio.In the experimental conditions, the suitable nitrogen application ratio was 138kg·hm-2, which significantly enhanced the rate of axillary bud germination.Therefore, panicle number in the second crop was 140% higher than that in the first crop, and its grain yield also nearly reached the level of the first crop.The economic benefit was the best among all treatments.
