摘要： 为了促进油菜生产的全程机械化作业研究，明确扬油6号对机械化作业的适应性，组织了不同品种的播期试验和扬油6号不同播期下的密度试验，结果表明扬油6号具有较高的产量水平和较强的耐迟播能力，在10月23日以前播种均能获得较高的产量水平。在不同播期条件下，密度对扬油6号产量有较大的影响。随着播期的推迟，较高的密度（60万株/hm2、75万株/hm2）对扬油6号的产量水平较好的补偿作用。同时，随着的密度的提高，株高、茎粗等性状也明显下降，更利于机械收割。说明扬油6号对机械化作业有较好的适应性。

Abstract: To enhance the research of mechanized operation for rapeseed, and understand the Yangyou NO. 6 suitable for mechanized operation, Field experiment were conducted on the sowing-date research of different varieties and density research of Yangyou No.6 under the different sowing-dates. Results showed that Yangyou No.6 had a higher output level and stronger ability to tolerate later sowing, and they all could have higher yield sowing before Oct.23. Under the condition of the different sowing-dates, the density had greater influence on Yangyou No.6's output. With the postponement of sowing-date, higher density (60×104plants/hm2、75×104plants/hm2)had better compensation function to output level of Yangyou No.6. Meanwhile, with improvement of density, some properties as shoot height, stem thickness were too obviously dropping, and more benefit to harvest by machine. From the experiments, Yangyou No.6 have better suitable for mechanized operation.
