16个水稻品种在宿迁地区的种植表现

Planting Performance of 16 Rice Varieties in Suqian Area

[目的]筛选适合宿迁地区机插秧种植的水稻品种,以满足当地对机插栽培早熟品种的需求,同时扩大机插秧面积,提高水稻种植机械化程度。[方法]比较16个水稻品种在宿迁地区的生育期、农艺性状、经济性状等指标。[结果]秀水519、皖垦糯1号、圣稻740等品种全生育期较长;圣稻20、圣稻020、精华2号、临稻11、新丰5号等品种株高都在105 cm以上,后期存在倒伏减产的风险;圣武糯0146、津稻253等品种株高较矮,产量潜力受限制,圣稻19与对照相比穗型略小、产量略低;阳光800、临稻16、中06-1、中作稻2号4个品种全生育期短,株高都在100 cm左右,抗倒伏能力强,株型适中,穗型较大,产量潜力高。[结论]阳光800、临稻16、中06-1、中作稻2号等品种具有高产潜力,适宜在宿迁地区机插种植。

[Objective] To screen the rice varieties suitable for the machine seedling planting of Suqian Area,to expand the area of machine seedling planting,and to enhance the rice planting mechanization degree. [Method]The growth periods,agronomic traits and economic characters of 16 rice varieties in Suqian Area were compared. [Result]Qiushui 519,Wankennuo 1 and Shengdao 740 had relatively long growth period. Plant heights of Shengdao 20,Shengdao 020,Jinghua 2,Lindao 11 and Xinfeng 5 were all greater than 105 cm,there were risks of lodging production in later period. Shengwunuo 0146 and Jindao 253 had relatively low plant heights,and the yield potential was restricted. Compared with control,Shengdao 19 had smaller ear shape and low yield. Yangguang 800,Lindao 16,Zhong 06-1 and Zhongzuodao 2 had relatively short growth period,strong lodging resistance capability,high yield potential,moderate plant type,and big ear type; their plant heights were all around 100 cm. [Conclusion]Yangguang 800,Lindao 16,Zhong 06-1 and Zhongzuodao 2 have high yield potential,and are suitable for machine planting in Suqian Area.
