植物生长调节剂在温室蔬菜生产上的应用是多种多样的。如促进扦插生根,打破休眠,促进抽薹开花,抑制徒长,培育壮苗等。现分别介绍如下:1 促进扦插生根 这是生长素在生产上应用最早的一个方法。温室栽培的大白菜和甘蓝,其叶、芽扦插时最好是用萘乙酸(2000mg/kg的快速浸蘸法。以砻糠灰、砂、珍珠岩作为扦插基质,经过10～15天可以生根及发芽。每一扦插单位,包括一个腋芽,一小段叶球的中柱(茎)组织,及一段叶片的中肋。每一叶球有多少张叶片,就可以繁殖多少株。用萘乙酸处理时,以蘸到茎组织的底面即可。
Plant growth regulators in the greenhouse production of vegetables is varied. Such as promoting cutting rooting, breaking dormancy, promote bolting flowering, curb leggy, nurturing strong seedlings. Are introduced as follows: 1 promote cuttings rooting This is the first application of auxin in the production of a method. Greenhouse cultivation of Chinese cabbage and cabbage, leaves, bud cutting is best to use naphthalene acetic acid (2000mg / kg fast dipping method to chaff ash, sand, perlite as a cutting substrate, after 10 to 15 days can root And sprouting.Each cuttage unit includes an axillary bud, a small segment of midrib (stem) tissue of the leaf bulb, and a midrib of a leaf blade.With how many leaves each leaf blade has, When dip to the underside of the stalk tissue.
