黑龙江省农科院研制出一种工厂化快速生产马铃薯脱毒原原种新方法——无基质定时气雾栽培法,最近通过了专家鉴定。无基质定时气雾栽培法就是将马铃薯脱毒苗直接固定在空气中,定时、定量向其根部喷施营养液,促使植株生长,达到结薯目的。 马铃薯靠块茎无性繁殖来繁衍后代,在种植过程中极易感染和积累病毒,造成减产。利用生物技术离体培养带有一二个叶原基的茎尖生产点,脱除或减少病毒粒子的含量,培养和快速繁殖脱毒试管苗和脱毒原原种供生产应用,是目前 Heilongjiang Academy of Agricultural Sciences has developed a factory to quickly produce a new method of potato virus-free protozoa - matrix-free time aerosol cultivation method, recently passed the expert identification. Baseless timing aerosol cultivation method is the potato virus-free seedlings directly fixed in the air, regular, quantitative spray to the roots of nutrient solution, to promote plant growth, to achieve the purpose of tubers. Potato asexual reproduction by tubers to multiply offspring, in the planting process is extremely vulnerable to infection and accumulation of viruses, resulting in reduced production. The use of biotechnology in vitro culture stems with one or two leaf primordium point of production, removal or reduction of virus particle content, culture and rapid propagation of virus-free plantlets and detoxification of the original seed for production and application, is currently
