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.
Abstract
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.
