引言马铃薯茎尖脱毒后经网室生产出的原原种数量有限,加快其繁殖速度,扩大繁殖倍数,是将脱毒薯尽快用于生产的关键.1983年,我们采用纸钵育苗.此法需要大量的马粪、床土、信封、木料、塑料等,投资较大.又因早春地温低,出芽慢,影响繁殖速度.1985年,我们采用电热线控温循环掰芽的无土育苗方法,收到了较好的效果. Introduction Potato stem tips detoxification produced by the net room after the limited number of the original species to speed up its breeding speed, multiplication of multiplication, is the key to the production of virus-free as soon as possible in 1983, we use potting seedlings. Law requires a lot of horse manure, bed soil, envelopes, wood, plastic, etc., due to a large investment in early spring because of low temperature, slow budding, affecting the breeding speed.In 1985, we use hotline temperature control loop breaking buds of soilless nursery Method, received a good result.
