随着脱毒马铃薯在农业生产上的应用,已获得较大的社会效益和经济收益。目前,人们已经改生产一、二级种薯为试管苗的扦插繁殖微型种薯,解决了生产上调种量大、费运高、亩播量多等问题。那么,如何才能提高脱毒种薯扦插产量?必须做到以下六个方面技术措施:1.选择种苗:选用脱毒彻底、干净、经监测不带病毒的试管苗、且生长健壮、发育正常的苗子用来做扦插的基础苗,坚决陶汰带有病毒的单株或试管,以防下代种子重新感病。2.剪苗长度要适中,处理好苗子:剪苗时必须用1～2‰的高锰酸钾或 With the application of virus-free potato in agricultural production, it has obtained greater social and economic benefits. At present, people have changed the production of one or two kinds of seedlings of test-tube seedlings of cutting propagation micropropagation, to solve the production of raised large amount of fees, transport fees, acres of sowing and other issues. So, how can we improve the yield of detoxification seed cutting? Must do the following six aspects of technical measures: 1.Selection of seedlings: Selection of detoxification thoroughly, clean, monitored without virus in vitro, and robust growth, normal development The seedlings used to do the basic cutting seedlings, and resolutely eliminate single plants or test tubes with a virus to prevent the next generation of seed re-susceptible. 2. Cut length to be moderate, handle seedlings: cut seedlings must be 1 to 2 ‰ of potassium permanganate or
