摘    要: 采用草炭+ 蛭石双层基质无土栽培和自动控制槽式喷雾栽培两种模式进行马铃薯脱毒小薯结薯数量及小薯质量分布比较, 同期定植, 结果表明70 d 生长期内前者每株匍匐茎数量为15 条, 膨大成薯5. 7 个, 后者匍匐茎数量为97 条, 膨大成薯76 个, 分别是前者的6. 5 倍和13. 3 倍。槽式雾培较基质无土栽培可显著提高脱毒小薯的繁殖系数。

关 键 词:马铃薯  脱毒小薯  槽式雾培  产量

Abstract:Both peat plus vermiculite double layer substrate culture and channel aeroponics were adopted in the study of tuberizing characteristics and minituber yield potential of virus-free(VF)potato plantlets in the same growing season.Trial results of the number and weight distribution of VF minituber indicated that,within 70-day growing period,stolons,total swelled minituber by substrate culture were 15 and 5.7 respectively,while data obtained from aeroponics were 97 and 76 accordingly.The latter were 6.5 fold and 13.3 fold of the former separately. Comparing with substrate culture,aeroponics significantly improve the minituber propagation coefficient.
Keywords:Potato  Virus-free minituber  Channel aeroponics  Yield
