1993～1994年在新疆石河子、北京大兴、山东济南、江苏扬州对多花品种掖单13和中花品种鲁玉10进行春播试验,采用高产群体剪叶剪穗,不同密肥培植大小不同群体研究了玉米群体主要源库指标与产量的关系。结果表明:尽管玉米产量因试点经纬度及生态条件的差异很大,但不同试点的玉米产量水平均随花后干物质积累量(源)、总粒数(库)的增加而增加,源库相互促进增产。但增源增产与增库增产比,增库增产更为重要。这方面花数少库容潜力小的品种比花数多库容潜力大的品种更为突出。
In 1993-1994, spring-sowing experiments were conducted on many flower varieties Yedan13 and Zhonghua variety Luyu10 in Shihezi of Xinjiang, Daxing of Beijing, Jinan of Shandong and Yangzhou of Jiangsu. The populations of different size and density The relationship between the main source and sink index of maize population and yield. The results showed that although the yield of maize varied greatly due to the latitude and longitude of the experiment and the ecological conditions, the yield of maize in different experimental sites increased with the increase of dry matter accumulation (source) and total grain number Promote increased production. However, incremental production and incremental library increase production, increase the library production more important. In this respect, the varieties with a small population of flowers with a small potential for their storage capacity are more prominent than the varieties with large numbers of flowers with large storage capacity.
