摘要[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。

Abstract[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 061 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 061 and Zhongzuodao 2 have high yield potential, and are suitable for machine planting in Suqian Area.

宿遷位于江苏省北部、长江三角洲地区,区域内地势平坦,水源充足,是传统的商品粮生产基地。近年来该地区机插秧面积逐步扩大,对熟期早、综合抗性优良、适宜机插的水稻品种需求加大。2015年宿迁市农业科学研究院引进16个水稻品种在自有基地示范种植,以筛选适合宿迁地区机插栽培的水稻品种,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。

1材料与方法

1.1试验材料试验选用的16个水稻品种都为常规粳稻品种,审定品种10个,正在参加各类试验品种5个,对照品种1个(连粳7号)。参试品种及推荐单位分别为圣稻19(山东济宁水稻研究所),圣稻20(山东济宁水稻研究所),圣稻0140(山东济宁水稻研究所),圣稻020(山东济宁水稻研究所),精华2号(江苏欢腾农业有限公司),秀水519(浙江勿忘农种业股份有限公司),皖垦糯1号(合肥皖垦种业股份有限公司),阳光800(郯城县种子公司,连云港神州种业),津稻253(山东润农种业科技有限公司),临稻11(沂南县水稻研究所),临稻16(沂南县水稻研究所),中06-1(江苏省泗棉种业有限责任公司),中作稻2号(江苏金万禾农业科技有限公司),圣稻740(江苏天隆种业科技有限公司),新丰5号(河南丰源种子有限公司)。

1.2试验地概况试验安排在宿迁市农业科学研究院水稻试验基地。基地位于泗阳县(118.68°E,33.73°N),境内气候温和湿润、四季分明、光照充足、雨水充沛,属北亚热带季风过渡性气候区,是传统的水稻耕作区。试验田块前茬为空地,土壤类型为黏土,肥力中上,土地平整,周围无化学污染源。
