Abstract
A field experiment was carried out to explore the effects of bud fertilizer on agronomic traits and yield formation of ratoon rice, using Huanghuazhan as material, urea as nitrogen fertilizer. The results showed that: in the application of the same seedling fer-tilizer (urea 225 kg/hm2) conditions, with the increase of the amount of bud fertilizer, the yield, plant height, ear length, spike rate and final regeneration rate of Huanghuazhan were increased in the regeneration season, and the grains per panicle and seed setting rate were increased first and then decreased, but 1000-grain weight had no obvious change. There were significant positive correla-tion between the amount of bud fertilizer and the yield and effective panicles of Ratoon rice. When bud fertilizer is 300 kg/hm 2, the yield of ratoon rice was the highest(4633.8 kg/hm2), and increased by 22.69%compared with no bud fertilizer treatment.关键词
