- 摘要:
- 针对齐齐哈尔地区降雨较少且时空分布不均,水稻传统栽培模式下泡田整地用水量大等问题,采取水稻机械旱直播栽培模式,省去传统种植泡田、育秧、移秧等环节,实现水稻生产节水节本。为选择适宜该区的旱直播品种,采用田间直接鉴定法,对不同品种抗病、抗倒伏和抗旱性及产量等进行了比较。结果表明:综合各项指标来看,龙庆稻5号、绥粳18和龙粳31是适宜齐齐哈尔地区种植的旱直播品种。
- Abstract:
- Aiming at the problems of less rainfall, nonuniform space-time distribution in Qiqihar area, and large amount of water consumption in field preparation under traditional rice cultivation mode,rice direct seeding by machine was adopted to eliminate the traditional field steeping,seedling raising, seedling transplanting and other links,achieving water and cost saving in rice production.In order to select suitable dry direct seeding varieties for this area, we compared disease resistance,lodging resistance,drought resistance and yield of different varieties by field direct identification method.The results showed that all indices considered, Longqingdao 5,Suijing 18 and Longjing 31 were suitable for direct seeding in Qiqihar area.
