小麦播期对干物质积累的影响分析

Analysis on Seed-times effected the Amount of Accumulating Dry-matter

[目的]通过不同小麦品种播种期种植试验,研究播种期对小麦干物质积累的影响。[方法]主要采用分期播种的方法,选择里下河地区的当家品种扬麦158、苏麦6号、宁麦9号进行种植试验。[结果]冬前期干物质积累量苏麦6号和扬麦158比较接近,宁麦9号比较低;拔节期干物质积累量苏麦6号、宁麦9号和扬麦158之间都比较接近;成熟期干物质积累量宁麦9号>苏麦6号>扬麦158。[结论]综合考虑小麦干物质积累量与播期的关系,里下河地区小麦的最佳播期为10月25日左右。

[Objective] Used bleeding experiment,Analysis on seed-times to effect with the amount of accumulating dry-matter in Lixiahe district of Jiangsu Province.[Method] Main way was to use by stages seed-times,bleeding experiment of Sumai 6 and Ningmai 9 and Yangmai 158 in Lixiahe district of Jiangsu Province.[Result] The amount of accumulating dry-matter of Sumai 6 is same Yangmai 158,it is higher than Ningmai 9 in the phase before winter.The amount of accumulating dry-matter of Sumai 6 is same Yangmai 158 and Ningmai 9 in the phase of pulled up burl.The amount of accumulating dry-matter of Sumai 6 is more than Yangmai 158 and more than Ningmai 9 in harvested phase.[Conclusion] Considered the relationship between wheat the amount of accumulating dry-matter and seed-time,the ideal wheat seed-times is twenty-fifth October near for planting aim of high yield and quality.
