蘖节繁殖是利用营养生长期的分蘖节,进行剥蘖扦插再生育苗繁殖,使一苗扩大为多苗,然后再移栽到大田的一种栽培方式。根据国内外遗传学者的研究认为,杂种通过无性繁殖能够保持亲体的遗传属性,使杂种F_1的基因表现型持续地发生作用,从而保持杂种优势。蘖节繁殖属于无性繁殖的范畴, Tillering Festival is the use of vegetative growth of tillering Festival, stripping and cutting cuttings reproductive nursery reproduction, so that one seedlings expanded to more seedlings, and then transplanted to the field of a cultivation method. According to the studies of geneticists both at home and abroad, it is considered that the hybrids can maintain the genetic properties of the parents through the asexual reproduction, and the genetic phenotypes of the hybrid F_1 can continue to exert their functions to maintain the heterosis. Tillering propagation belongs to the category of asexual reproduction,
