马铃薯无土栽培营养液研究进展

Progress in Nutrient Solution Research for Potato Soilless Cultivation

营养液是马铃薯无土栽培过程中植株养分供给的主要来源,很大程度上决定着马铃薯无土栽培的成败。无土栽培马铃薯的生长分为幼苗期、块茎形成期、块茎增长期、淀粉积累期、成熟期五个时期,不同时期对营养的需求有所不同。营养液配方、pH、EC值、温度、喷施频率均影响无土栽培马铃薯的生长发育。文章总结了马铃薯生长过程的营养需求规律,综述了马铃薯无土栽培营养液配方、营养液管理等研究现状,为后续深入研究和应用提供了依据。

Nutrient solution is the main source of nutrient supply in potato soilless cultivation,which determines the success or failure of potato soilless cultivation to a great extent.The growth of potato in soilless cultivation can be divided into five stages:seedling stage,tuber formation stage,tuber growth stage,starch accumulation stage and maturity stage.The nutritional requirements in different stages are different.Formulation,pH,EC,temperature,spraying frequency of the nutrient solution affect potato growth and development in soilless cultivation.The patterns of nutrient requirement for potato were summarized,and the research status of the nutrient solution formulation and management in potato soilless cultivation were reviewed,which would provide basis for subsequent research and application.
