摘要
马铃薯栽培范围遍布全世界,在我国每年种植面积超过467×10^(4)hm^(2),掌握其需水需肥规律及水肥耦合机制有助于马铃薯优质高产栽培。文章在综述国内外水肥一体化发展的基础上,重点阐述了马铃薯水肥耦合效应及膜下滴灌对土壤水热传输、水盐运移规律的影响特性,同时探讨了当前膜下滴灌技术仍然存在的问题和应对措施,以期为膜下滴灌在马铃薯栽培中的应用提供参考。
Potato cultivation is spread all over the world,and the annual planting area in China is more than 4.67 million hectares.Understanding the law of water and fertilizer demand and the coupling mechanism of water and fertilizer is helpful to the cultivation of potato with high quality and high yield.Therefore,on the basis of summarizing the integrated development of water and fertilizer at home and abroad,this paper focused on the coupling effect of potato water and fertilizer and the characteristics of the influence of submembrane drip irrigation on soil water and heat transfer and water and salt transport.At the same time,the existing problems and countermeasures of submembrane drip irrigation technology are discussed,in order to provide references for the application of sub‐membrane drip irrigation in potato cultivation.
