套种油菜与直播油菜比较,产量差异不显著(P>0.05),但产值却提高189.7元/亩,且以1.33m带型最优。播期、施肥方式和多效唑均可影响油菜产量(P<0.05或P<0.01),9月1日播种,采用底肥+春肥的施肥方式,苗期叶面喷施2％尿素产量最高。多效唑可降低套种油莱产量。
Compared with direct seeding rape, there was no significant difference in yield between rapeseed and rapeseed (P> 0.05), but the output value increased by 189.7 yuan / acre, and the optimum was 1.33 m. Sowing date, fertilization mode and paclobutrazol could affect the yield of rapeseed (P <0.05 or P <0.01). Seeds were planted on the 1st of September. Fertilizer application of base fertilizer and spring fertilizer had the highest yield of 2% urea at the seedling stage. Paclobutrazol can reduce intercalary oil production.
