摘要
在防虫网棚松针腐殖土上,研究不同培土次数对脱毒薯产量及植株性状的影响,探索适宜的培土次数及培土厚度。以‘宣薯2号’脱毒苗为试验材料,测定不同培土次数下的脱毒薯产量、各级别脱毒薯比率、合格率、植株特性及薯皮绿化率。研究结果表明:以培土2次处理单位面积上合格薯产量最高,为283粒/m2。在毕节市海拔1 450 m的网棚内松针腐殖土上繁育‘宣薯2号’原原种适宜培土2次,苗床与2次培土厚度累计为9 cm。
Effects of various times of earth up on minituber yield and plant traits of in vitro plantlets transplanted to nursery bed, which was made of humus soil of pine forestry in a insect-proof net house, were studied in order to understand the suitable times of earth up and thickness of the coverage for minituber production. Minituber yield and weight distribution, qualified minituber percentage, plant trait, and greening tuber percentage were investigated using the variety ＇Xuanshu 2＇ in vitro plantlets as plant material. The results indicated that earth up two times gave the highest qualified minituber yield （283 piece/m^2）. For the minituber production of＇Xuanshu 2＇ in the humus soil of pine forestry in a insect-proof net house at 1 450 m asl in Bijie, the suitable times of earth up is two and the total thickness of bed soil plus two-time earth up is 9 cm.
