摘要
生产脱毒马铃薯原原种采用稀植培育壮苗，每株最大薯块达3～4g时，及时收获，将植株重新定植，可使试管苗结出更多的微型薯，一般20d左右可进行2次收获，以后还可进行1～2次收获，大大地提高了试管苗的单株结薯率．减少试管苗的用量，降低生产成本64％左右。
The original-original potato seeds without virus pollution can be produced by culturing strong seedlings. When the maximum mini-potato is 3 g to 4 g, these mini-potatoes are harvested in time and then the harvested seedlings are cultured again to harvest more mini-potatoes after about 20 d. The process can continue 1 to 2 times repeatedly. The technique can raise setting potato rate per seedling and reduce about 64 % of production cost.
