摘　　要：以甬优2640为材料,在连江作早稻机收再生栽培。表现生育熟期早、穗型大、结实率高、抗倒性强、增产潜力大、综合性状好,再生季产量高。2个示范点头季平均每667m2产量507.55 kg,比佳辐占增产27.3%。再生季平均每667m^2产量231.3 kg,比佳辐占增产33.24%。总结了甬优2640作早稻机收再生的栽培技术要点。Yongyou 2640 was planted by mechanical harvesting as ratooning rice of early season in Lianjiang county. It was characterized by short growth duration, big spike, high fertility, strong lodging resistance, good comprehensive characters and high yield in ratooning season. In the two model test points, the average yield of main cropping was 507.55 kg per 667m^2, 27.3% higher than that Jiafuzhan, and the average yield of ratooning cropping was 231.3 kg per 667m2, 33.24% higher than that Jiafuzhan. In this paper, we introduced cultivation techniques by mechanical harvesting as ratooning rice of Yongyou 2640 in early season.
