吉林省中部地区马铃薯中棚种植试验

Planting Potato in Medium Sized Plastic Tunnel in Central Part of Jilin Province

试验利用中棚保护地,选择不同品种和栽植密度,模拟大田马铃薯种植条件种植,寻找适合中棚种植的马铃薯品种及合理的种植密度。结果表明:中棚条件下早熟马铃薯以‘荷兰7’产量较好;‘荷兰7’和‘早大白’两个品种均以密度21 cm×70 cm鲜薯产量最高,与对照25 cm×70 cm(CK)产量比分别增产13%和16%,差异显著。因此,中棚可以种植马铃薯,品种应选‘荷兰7’,种植密度以21 cm×70 cm最为适宜。

Two potato varieties were planted in various densities in medium sized plastic tunnel in order to select the potato variety suitable for planting in medium sized plastic tunnel at optimal density. The results indicated that＇Helan 7＇ was better than the other in yield; both varieties, ＇Helan 7＇ and ＇Zaodabai＇, performed better at the density 21 cm × 70 cm than other densities, outyielding the control 25 cm × 70 cm by 13% and 16%, respectively. Therefore, potato could be grown in a medium sized plastic tunnel, and the variety ＇Helan 7＇ should be selected and planted atthe density 21 cm × 70 cm.
