中文摘要:
      马铃薯原原种气雾栽培法是一种新型的无土栽培技术,相较传统栽培方式,具有较多优势。调控营养液营养元素是获得 马铃薯原原种高产的关键技术。以马铃薯“米拉(Mira)”品种的脱毒试管苗为试验材料,在水培壮苗培养阶段采用 Box-Behnken设计,对改良霍格兰营养液中硝酸钾、磷酸二氢钾、硝酸铵的比例进行了优化。优化后(即优化霍格兰)的营养液 中三者的比例为:硝酸钾645 mg/L、磷酸二氢钾230 mg/L 、硝酸铵120 mg/L,采用此营养液用于后续的原原种气雾栽培试验。 优化霍格兰在雾培马铃薯植株生长阶段与改良霍格兰和荷兰配方相比,株高和叶面积显著增加,但是匍匐茎数和匍匐茎分枝 数低于后两者。在雾培马铃薯结薯期,与营养液中采用230 mg/L磷酸二氢钾喷雾相比,330 mg/L磷酸二氢钾喷雾可显著增加 单株结薯数,530 mg/L的磷酸二氢钾喷雾可显著增加单粒重和最大单薯重。雾培马铃薯的不同生育时期可采用不同的营养 液,但需要加以验证才能用于大规模生产。
英文摘要:
      As a soilless cultivation technique developed in recent years, aeroponic cultivation has many advantages over traditional cultivation methods. Regulation of nutrient elements in nutrient solutions is a key technique for higher yields of mini-size potato. In our study, virus-free cuvette plantlets of potato cultivar 'Mira' were used as test materials, and at the stage of hydroponic seedling, the ratio of KNO3, KH2PO4 and NH4NO3 in improved Hogagland solution were optimized by Box-Behnken design. The optimized ratio of the three nutrients (i.e., optimized Hoagland) were: KNO3 645 mg/L, KH2PO4 230 mg/L and NH4NO3 120 mg/L, and this nutrient solution was used for the follow-up test of aeroponic cultivation of mini-size potato species. At the plant growth stage in the aeroponic cultivation, the heights and leaf sizes of potato plants cultivated by optimized Hoagland formula both increased significantly compared with those of potato plants cultivated by improved Hogagland and Dutch formulas, but the numbers of stolons and stolon branches of plants cultivated by optimized Hoagland formula were lower than those of plants cultivated by the latter two formulas. At the stage of tuber formation, potato plants cultivated with 330 mg/L KH2PO4 produced a significantly larger number of tuber per plant than those cultivated with 230 mg/L KH2PO4, and 530 mg/L KH2PO4 can significantly increase single tuber weight and the biggest tuber weight. Different nutrient solutions can be used at different potato growth stages in the aeroponic cultivation, but they need to be further tested and verified before their applications to large-scale potato cultivations.
