2012～2013年在冬油菜主产区布置15个田间试验研究油菜长效专用配方肥( N-P2 O5-K2 O-B：20-7-8-0.2,及5%的其他中、微量元素)的施用效果,为油菜一次性施肥配方的推广及改进提供依据.结果表明,与不施肥处理相比,常规施肥与专用肥均能明显提高油菜籽产量、收入及养分吸收量.与常规施肥相比,在减少总养分用量且肥料一次性施入的情况下,油菜长效专用配方肥在85%以上的试验点表现出增产或稳产效果,平均增产量为133 kg/hm2,增产率为8.1%,增加经济收益1624元/hm2.施用油菜长效专用配方肥促进了油菜对养分的吸收, N、 P2 O5、 K2 O累积量较常规施肥分别增加10.8、2.1、7.9 kg/hm2.研究表明,油菜长效专用配方肥对油菜产量的贡献率平均为51.8%,农学利用率平均为5.5 kg/kg,均高于常规肥料.整体而言,施用油菜长效专用配方肥能提高油菜产量和施肥效益,可作为油菜轻简化施肥技术进行推广应用.

Field experiments on winter oilseed rape were conducted at 15 sites in main producing areas during 2012~2013. The objective of this research was to study the effects of applying slow-released special formula fertilizer ( N-P2 O5 -K2 O-B 20-7-8-0. 2, and other mid-nutrients and min-nutrient 5%) on oilseed rape, and then to provide the basis for the promo-tion and improvement of single fertilization for winter oilseed rape. The results showed that both the application of conventional fertilizer and formula fertilizer on winter oilseed rape could significantly increase the yield, net profit and nutrients uptake. Compared with conventional fertilizer treatment, when the total amount of nutrients was reduced and fertilizer single application was used, yields of more than 85% of the test points in the slow-released special formula fertilizer treatments were increased or equal, with that the average yield, increase rate and the average increase income was 133 kg/hm2 , 8. 1% and 1 624 Yuan/hm2 respectively. Nutrient uptakes were obviously improved in formula fertilizer treatments, with the average accumulation in-creased by N 10. 8 kg/hm2 , P2 O5 2. 1 kg/hm2 , K2 O 7. 9 kg/hm2 . It showed that the average fertilizer contribution rate to yield and agronomic efficiency were 51. 8% and 5. 5 kg/kg, respectively, which were both higher than those of conventional fertilizer treatment. On the whole, the application of slow-released special formula fertilizer on winter oilseed rape could sig-nificantly increase the yield and net profit and it could be promoted and applied as one of simplify fertilization techniques for winter oilseed rape.
