摘要
[目的]加快新品种川麦51的推广应用速度,明确其配套高产栽培技术,实现其应用价值。[方法]在四川省广汉连山地区和四川省金堂县分别开展了川麦51的密度、施肥量试验和播期试验。[结果]在广汉连山地区,施氮量达到12 kg/667m2,基本苗为14.32×104/667 m2时,产量最高,适宜播期为10月26日;在四川省金堂县,施氮量达到15kg/667 m2,基本苗为16.1×104/667m2时,产量最高,最佳播期为10月28日。[结论]川麦51适宜在四川省内各麦区及云南、贵州、湖北、陕西汉中等部分麦区种植,一般在10月底播种,基本苗保持在16×104/667 m2以上。
[Objective] The application value of the wheat variety-Chuanmai 51 would be realized through the acceleration of its extension based on the research on corresponding high-yielding cultivation technique of Chuanmai 51.[Method] The experiment in the planting density,fertilization and sowing time was carried out in the Lianshan,Guanghan and Jintang city.[Results] The results showed that the sowing time should be on October 26 in the region of Lianshan and Guanghan city while the nitrogen rate was 12 kg/667m2 and the number of basic seedling was 143.2 thousand plants/667m2 so that the Chuanmai 51 yield reached the highest level,and in the Jintang city,the highest yield Chuanmai 51 could be reached while its sowing date was October28 based on the nitrogen rate of 15 kg/667m2 and the basic seedling of 161 thousand/667 m2.[Conclusion] The Chuanmai 51 was suitable for the planting in Sichuan province,the partial region of Yunnan,Guizhou,Hubei province,and Hanzhong of Shaanxi province,which sowing date usually was in late October and the basic planting density was at over 160 000 seedlings/667 m2.
