研究结果表明，马铃薯脱毒试管扦插苗在保持根际黑暗条件下，采用无基质定时喷雾供给养分，在温室或大棚等保护地内可生产马铃薯脱毒小薯（原原种）。单株可结薯５０～６０粒，重量８～１０ｇ／粒，每ｍ２可结薯８００～１０００粒，其中Ｂ组营养液效果最佳。
The results showed that the potato virus-free test tube cutting seedlings maintained the nutrient solution in the rhizospheric dark with no matrix timing spray and could produce potato detoxification potato (original seed) in protected areas such as greenhouses and greenhouses. Individual plants can tuber 50 ~ 60, weight 8 ~ 10g / grain, each tub can end tuber 800 ~ 1000, of which the best effect of B group of nutrient solution.
