摘    要：为了筛选出适合山东省临沂市大跨度拱棚春早熟栽培的马铃薯品种，于2020年进行了5个品种的比较试验。试验结果表明，不同品种的生育期有明显差异，‘荷兰806生育期最短为65 d，‘希森3号最长为82 d。民丰优选商品薯率最高，达到96.5%，商品薯产量也最高达到36 217.1 kg·hm-2。荷兰806产量低，但上市时间最早，其产值最高达到110 787.6元·hm-2。‘民丰优选和‘荷兰806植株较矮，株高分别为45.3 cm和44.6 cm。‘荷兰15和‘荷兰806对马铃薯早疫病抗性较好，早疫病病株率分别为10.1%，11.6%，早疫病病情指数分别为9.7，10.1。‘荷兰15和‘荷兰806对马铃薯晚疫病抗性也较好，晚疫病病株率分别为18.3%，15.2%，晚疫病病情指数分别为17.1，15.9。‘民丰优选和‘荷兰806适宜在临沂市进行大跨度拱棚春早熟马铃薯栽培。

Abstract： In order to select suitale potato varieties for spring early-maturing in large-scale arch shed in Linyi City of Shandong Province，we compared five varieties of potato in 2020.The results showed that：'Helan 806' had the shortest growth period，only 65 days; 'Xisen 3' had the longest growth period， it was 82 days;'Minfengyouxuan' had the highest commodity rate of potato and yield，it was 96.5% and 36 217.1 kg per hm2 respectively. 'Helan 806' had lower yield，but it was early maturing and had the highest value for 110 787.6 yuan per hm2. 'Minfengyouxuan' and 'Helan 806' had shorter plant height， it was 45.3 cm and 44.6 cm respectively.'Helan 15 'and 'Helan 806' had better resistance to potato early blight，the rate of diseased plant was 10.1% and 11.6% respectively; the disease index of potato early blight was 9.7 and 10.1 respectively. 'Helan 15' and 'Helan 806' had better resistance to potato late blight， the rate of diseased plant was18.3% and 15.2% respectively; the disease index of potato late blight was 17.1 and 15.9 respectively. 'Minfengyouxuan' and 'Helan 806' are suitable for sping early-maturing cultivation in large-scale arch shed in Linyi City.

2019年，山東省临沂市马铃薯栽培面积1.438万hm2，其中地膜覆盖栽培面积1.323万hm2，但由于产品上市集中，种植效益不高。近年来，新型大跨度拱棚因其空间大，操作方便，保温性好，逐渐受到当地菜农喜爱。胡海波等[1]对日光温室春茬马铃薯品种进行了筛选试验，发现不同品种产量差异明显，表现较好的为‘大西洋和‘荷兰15。张春强[2]对日光温室脱毒马铃薯品种进行比较试验，通过分析‘中薯3号、‘津引8号、‘郑薯5号、‘东农303的生育期、大薯率、产量等，筛选出适合洛阳地区早春日光温室种植的马铃薯品种。张国森等[3]在跨度10 m大拱棚内进行蔬菜有机生态型无土栽培，每公顷产值达30万元以上。杨子强等[4]在大跨度拱棚内进行一年三茬周年栽培，实现了蔬菜周年生产。……
