摘  要:
[目的]探求华粳5号高产栽培的技术途径。[方法]开展华粳5号不同密度机插试验、高产示范方研究。密度试验株行距分别为30.0 cm×15.0 cm、30.0 cm×13.3 cm、25.0 cm×12.5 cm、25.0 cm×12.0 cm、20.0 cm×13.5 cm。[结果]华粳5号分蘖性中等,机插密度以25.0 cm×12.0 cm较为适宜;基蘖肥与穗肥氮施用比例以7∶3最佳,促早发,中期控群体,后期攻大穗,容易获得高产。[结论]该研究可为华粳5号的大面积推广应用提供理论和实践依据。

摘  要:
[Objective]The aim was to find out the high yield cultivation way of Huajing No.5.[Method]The different sowing density and mechanical transplanting test and high yield demonstration farms study were conducted on.And the spacing in the rows and between rows was 30.0 cm × 15.0 cm,30.0 cm × 13.3 cm,25.0 cm × 12.5 cm,25.0 cm × 12.0 cm,20.0 cm × 13.5 cm,resp..[Result]Huajing No.5 has medium tillering ability,and the more suitable mechanical transplanting spacing in the rows and between rows is 25.0 cm × 12.0 cm;the best nitrogen fertilizer application ratio of base-tiller fertilizer and earing fertilizer is 7∶ 3,which promotes early germination,controls rice groups in the middle stage of growth,attacks big spike in the last stage of growth,so obtains high yield easily.[Conclusion] The study provides a theoretical and practical basis for promotion and utilization of Huajing No.5 in a large scale.
