番茄在我国为主要蔬菜栽培作物,其杂交种子已经在生产中得到广泛应用。杂交种子的质量指标较高,国标一级规定纯度98％以上,发芽率85％以上。研究番茄杂交制种技术,对于保证产品种子质量,提高种子产量和种植效益,促进番茄生产发展具有重要意义。 一、培育壮苗是保证产量的基础 壮苗应具有发达的根系,株高25厘米左右,7～9片真叶,茎秆粗壮,叶色正常,现蕾或顶花。
Tomatoes are cultivated in China as the main vegetables, and their hybrid seeds have been widely used in production. Hybrid seeds of higher quality indicators, a national standard purity of 98% or more, the germination rate of 85% or more. Studying tomato hybridization seed production technology is of great significance to ensure product seed quality, increase seed yield and planting benefit, and promote tomato production and development. First, to nurture strong seedling is to ensure that the production of strong seedlings should have developed roots, about 25 cm in height, 7 to 9 true leaves, stalks stout, leaf color normal, budding or top flowers.
