为探讨湖北省潜江地区油菜最高产量施肥量与产量、最佳施肥量与产量的关系,避免盲目施肥,做到科学施肥,从而达到油菜高产低耗、高效优质、持续环保的目的,在湖北潜江地区进行了油菜施肥“3414”设计试验。结果表明,N2P2K2为湖北省潜江地区油菜施肥最佳推荐配方,最佳施肥方案为施纯氮133.2kg/hm2、五氧化二磷53.4kg/hm2、氧化钾50.8kg/hm2,该配方可以在该区域推广应用。
In order to explore the relationship between the highest yield of fertilizers and yield, the best fertilization and yield in the Qianjiang region of Hubei Province, avoid blind application of fertilizers and scientific fertilization so as to achieve the purpose of high yield, low loss, high efficiency, high quality and sustainable environmental protection of rape, Qianjiang area rape fertilization “3414 ” design test. The results showed that N2P2K2 was the best recommended formula for rapeseed fertilization in Qianjiang of Hubei Province. The optimum fertilization program was 133.2kg / hm2 of pure nitrogen, 53.4kg / hm2 of phosphorus pentoxide and 50.8kg / hm2 of potassium oxide. The promotion of the region.
