根据多年的水稻生产技术推广实践及田间试验,从株叶形态、需肥特点、休眠芽发育进度、再生芽分布规律等方面比较了两系杂交稻与三系杂交稻的再生特性;总结出两系杂交稻再生稻高产栽培技术要点:适当多栽基本苗;重施底肥,早施和轻施分蘖肥,增施磷钾肥;保留倒2节或倒3节芽。 Based on many years of rice production technology popularization practices and field experiments, the regeneration characteristics of two-line hybrid rice and three-line hybrid rice were compared in terms of the morphological characteristics of leaves, the characteristics of fertilization needed, the progress of dormancy buds and the distribution of regenerated shoots. Department of hybrid rice ratoon high yield cultivation techniques: appropriate multi-planted seedlings; heavy base fertilizer, early and light applied tillering fertilizer, increased phosphorus and potassium fertilizer;
