摘　　要：为筛选适宜金华作直播栽培的早稻品种,以20个早稻品种为试验材料,比较分析不同早稻品种在直播栽培条件下的农艺性状和产量表现。结果表明,中嘉早17、甬籼15、中佳早18、嘉育25、甬籼409、中组143、舜达135、中组53、浙1613、中组100、甬籼634、中组18、浙1702和浙1708比中早39早熟1~4 d;金早239、舜达95、中组53和浙1613抗倒性一般或差;甬籼15、株两优831、金早239、中组143、中组100、甬籼634和浙1702比中早39增产0.1%~4.6%。甬籼15、中组143和中组100表现生育期短、丰产、抗倒,适宜在金华作直播栽培。In order to screen out the early rice varieties suitable for direct seeding cultivated in Jinhua,the agronomic traits and yield performance of 20 early rice varieties with direct seeding cultivation were comparatively analyzed in this paper.The results showed that,compared with Zhongzao 39,the whole growth period of Zhongjiazao 17,Yongxian 15,Zhongjiazao 18,Jiayu 25,Yongxian 409,Zhongzu 143,Shunda 135,Zhongzu 53,Zhe 1613,Zhongzu 100,Yongxian 634,Zhongzu 18,Zhe 1702 and Zhe 1708 were shortened by about 1-4 days.Jinzao 239,Shunda 95,Zhongzu 53 and Zhe 1613 showed poor lodging resistance.The yield of Yongxian 15,Zhuliangyou 831,Jinzao 239,Zhongzu 143,Zhongzu 100,Yongxian 634 and Zhe 1702 were increased by 0.1%-4.6%compared with Zhongzao 39.It was concluded that Yongxian 15,Zhongzu 143 and Zhongzu 100 were suitable for direct seeding cultivated in Jinhua,which showed shorter growth period,higher yield and good lodging resistance.
