Abstract

Aeroponics would appear to have a number of potential attributes to make potato production more efficient. In a 3-year experiment, from 2019 to 2021, potatoes were grown in aeroponic units using two nutrient solutions as well as in a conventional polycarbonate greenhouse in a substrate. Potato cultivars Adéla, Zuza and Ornella were used in all experiment years. No statistically significant effect of nutrient solution or potato cultivar on the number and weight of tubers was found in the trial. However, the advantages of aeroponics over conventional technology were statistically proven. The number of tubers per plant in aeroponic units ranged from 2.4 (2019, cv. Adéla) to 41.0 (2021, cv. Zuza), while in the greenhouse, they ranged from 3.9 (2019, cv. Adéla) up to 12.6 (2021, cv. Adéla). The average weight of tubers in aeroponic units ranged between 2.0 g and 9.9 g per plant (2 to 10 successive harvests), and in the greenhouse, 22.7 g to 41.9 g per plant (single harvest). The influence of cultivar on the average weight of tubers within individual cultivation technology variants was statistically proven only for polycarbonate greenhouse: only one harvest after the end vegetation.

在捷克共和国的条件下，空气栽培技术与传统马铃薯苗生产系统的比较

气培技术似乎有许多潜在的特性可以提高马铃薯的生产效率。在一项为期3年的实验中，从2019年到2021年，马铃薯在气培装置中种植，使用两种营养液，以及在基材上的传统聚碳酸酯温室中种植。所有试验年份均使用马铃薯品种ad、Zuza和Ornella。试验中未发现营养液和马铃薯品种对马铃薯块茎数量和重量的影响有统计学意义。然而，空气栽培技术相对于传统技术的优势已被统计证明。气培单位每株块茎数从2.4个(2019,cv。adz3)至41.0(2021年，cv。Zuza)，而在温室中，它们的范围从3.9 (2019,cv。adsamac)至12.6(2021年，cv。阿德拉)。气培单位的块茎平均重量在每株2.0克至9.9克之间(连续收获2至10次)，在温室中，每株22.7克至41.9克(单次收获)。在个别栽培技术变异中，栽培品种对块茎平均重量的影响仅在聚碳酸酯温室中得到统计证明:在终末植被之后只有一次收获。
