黄花菜的繁殖可通过有性和无性两种途径。过去主要以茎蘖无性繁殖为主,繁殖系数低,发展缓慢。种子育苗繁殖的新方法是我们在实践中摸索,并于1982—1984年的多点试验中获得成功的。它的主要特点是繁殖系数高,经济合算,还可提高种性和生活力。一般育一亩苗需种子5斤左右(每斤种子以50元计算,需250元),可保苗7万2千余株,当年秋季或第二年春可移栽30—36亩,第三年即可投产。这样栽植一亩黄花只需种子款6.94—8.33元,可
Day lily breeding can be sexual and asexual two ways. In the past mainly stems and tillers asexual reproduction, breeding coefficient is low, the development is slow. The new method of seedling breeding is that we explore in practice and succeeded in the multi-point experiment of 1982-1984. Its main feature is the high coefficient of breeding, economic and cost-effective, but also improve the species and vitality. General seedlings per acre need about 5 pounds of seeds (50 yuan per catty seeds to 50 yuan, 250 yuan), seedlings can be more than 7,000 2 thousand, then fall or second spring 30-36 acres of transplanting, the third year Can be put into production. This planted acres of yellow flowers only 6.94-8.33 yuan seed can be
