马铃薯脱毒原原种高产低耗快繁技术研究

本文对马铃薯脱毒原原种快速繁育的一些关键技术措施进行了系统的研究， 即采用广口玻璃罐头瓶、简化培养基、液体浅层静置培养脱毒苗； 脱毒苗剪顶扦插快速育苗； 脱毒苗一次栽苗， 两次收种； 脱毒苗喷施多效唑等。这些技术是高产、高效、低耗、快繁脱毒原原种的有效方法， 可在规模化生产脱毒薯中应用。

A STUDY ON HIGH YIELDING,LOW EXPENSIVE AND RAPID MULTIPLICATION TECHNOLOGY OF BASIC SEEDS OF VIRUS FREE POTATOES

This article studies systematically some key techniques on rapid multiplication of basic seeds of virus free potatoes and summarizes a set of production technology on high yielding,low expensive and rapid multiplication of virus free basic seeds.Virus free shoots are cultured by using glass jar and simplified medium,cultured in shallow liquid medium,and propagated rapidly by rooting shoot cutting.The shoots are planted one time,and the tubers are harvested twice.The shoots are sprayed with PP 333 .These techniques are used together,which are high yielding,effective and low expensive methods for rapidly multiplicating virus free basic tubers.They are popularized and used in mass production of virus free seeds.
