2013年秋季作物油菜配方肥验证及微肥试验技术

[目的]为考察不同含量的配方肥及硼肥对油菜的增产效果.[方法]在肥东县店埠镇群力村,按照县测土配方施肥项目推荐的区域配方用肥,对照当地习惯施肥及不施肥（空白）进行试验.通过田间调查和室内考种,比较不同处理对油菜生长发育、产量的影响.[结果]基肥中增加氮肥,绿叶数、开展度、株高、地上部干物质累积量、产量都相应增加,绿叶片、开展度增加以栽后35 d内明显,随着时间的推移,基肥中少量增氮对菜苗生长作用有限.[结论]基肥中适量增施氮肥可增加油菜产量;基肥中增施硼肥,可促进油菜的营养生长、生殖生长,大幅提高油菜产量.

Verification of Rape Formula Fertilizer in Autumn, 2013 and Micro Element Fertilizer Test

[ Objective ] The research aimed to study the yield-increasing effect of the formula fertilizer and boric fertilizer. [ Method ] In Quuli vil- lage, Dianbu Town, Feidong County, according to regional formula fertilizer recommended by the project of county soil testing and formulated fer- tilization, the test compared with local habit fertilization and no fertilizer was conducted. The effects of different treatments on the growth and the yield of rape were studied with field investigation and indoor test. [ Result] The treatment of adding nitrogen fertilizer to base fertilizer could in- crease green leaf opening degree, plant height, dry matter accumulation of overground plant and the yield, and green leaf number and opening degree leaf number were increased obviously in 35 d. With the time prolonged, the effect of a little nitrogen fertilizer added to base fertilizer was limited. [ Conclusion] Adding optimum amount of nitrogen fertilizer to base fertilizer could increase the yield of the rape. Adding boric fertilizer to base fertilizer could promote the vegetative growth and reproductive growth of the rape, and improve the yield of the rape significantly.
