The effects of container type on plant growth, yield and production cost of seed potatoes were investigated. Potato cultivars ‘Saebong’, ‘Geumsun’ (early-maturing) and ‘Haryeong’ (mid-maturing) were grown in four types of plant container: small (25 cm × 25 cm × 19 cm, L × W × H), medium (63 cm × 22 cm × 15 cm) and large (53 cm × 37 cm × 19 cm) plastic boxes and a styrofoam bed (100 cm × 52 cm × 31 cm). Shoot growth expressed as plant height was vigorous in the substrate culture system, especially in the styrofoam bed, whereas the roots tended to be longest in the small plastic box. ‘Haryeong’ showed the greatest shoot and tuber growth across plant container types. Tuber number (87.2–104.1 tubers m−2) and tuber weight (7.6–9 kg m−2) were greatest in the large plastic box and in the styrofoam bed. Furthermore, seed tuber (30–250 g) percentage of all tubers produced was high (93–95%), but no significant differences were observed among container types. The incidence of tuber physiological disorders was low (<5%). Considering the cost of the substrate, plant containers and stem cuttings, the production cost was lower for the medium and large plastic boxes, and for the styrofoam bed (20–39% lower), than that for the small plastic box. Therefore, the large plastic box and the styrofoam bed are suggested as ideal plant containers for the production of seed potatoes.

植物容器类型对种薯(Solanum tuberosum L.)在基质培养中生长和产量的影响

研究了容器类型对种薯植株生长、产量和生产成本的影响。马铃薯品种 'Saebong'、'Geumsun'(早熟)和 'Haryeong'(中熟)种植在四种类型的植物容器中:小(25 cm × 25 cm × 19 cm,长 × 宽 × 高),中号(63 cm × 22 cm × 15 cm)和大号(53 cm × 37 cm × 19 cm)塑料盒和一张泡沫聚苯乙烯床(100 cm × 52 cm × 31 cm)。在基质培养系统中,以植株高度表示的枝条生长旺盛,尤其是在泡沫聚苯乙烯床中,而在小塑料盒中的根往往最长。'Haryeong' 在植物容器类型中表现出最大的芽和块茎生长。块茎数(87.2-104.1 块茎 m -2)和块茎重量(7.6-9 kg m -2) 在大塑料盒和泡沫聚苯乙烯床上效果最好。此外,生产的所有块茎中的种子块茎(30-250 克)百分比很高(93-95%),但在容器类型之间没有观察到显着差异。块茎生理疾病的发生率较低(<5%)。考虑到基质、植物容器和茎插条的成本,中型和大型塑料箱的生产成本和泡沫聚苯乙烯床的生产成本(低 20-39%)比小塑料箱的生产成本低。因此,建议将大塑料盒和泡沫塑料床作为种薯生产的理想植物容器。
