摘　　要：为进一步筛选适合烟后机械种植的优质稻品种,选择合适秧龄,最大限度发挥机插秧的生产优势。2021年在福建省邵武市开展烟后稻机插品种筛选与不同秧龄生产试验,结果表明甬优1540、甬优4949、甬优7850等3个籼粳杂交品种以15~18 d秧龄作烟后稻种植为宜,籼型品种晶两优华占则由于生育期较长,存在安全齐穗问题,不宜在邵武市作烟后稻机插种植。Tests of four different post-tobacco rice varieties and four seedling age were carried out in Shaowu to clarify suitable rice varieties and seedling age,further to take full advantages of machine-transplanted seedling.Results showed that three indica/japonica hybrid varieties,Yongyou 1540,Yongyou 4949 and Yongyou 7850,were suitable for post-tobacco rice cultivation with seedling age of 15 to 18 days.JingliangyouHuazhan cannot ensure safety full heading due to longer growth duration,and it was not suitable for post-tobacco rice planting in Shaowu.
