摘要
[目的]获得安庆市大观区油菜作物在不同肥力水平条件下的推荐施肥量.[方法]通过"3414"回归最优设计原理,设置甘蓝型油菜作物的肥料田间试验.[结果]甘蓝型油菜"3414"试验得出的最佳施肥量是N 131.70~399.90 kg/hm2、P2O5 47.85~326.85 kg/hm2、K2O 77.55~320.25 kg/hm2.[结论]结合大观区当地实际,油菜推荐施肥量是N 180~360 kg/hm2、P2O5 120~150 kg/hm2、K2O 150~180 kg/hm2.
Abstract
[Objective]To obtain the recommended fertilization amount of rape under different fertility levels at Daguan District, Anqing City.[Method]To set up fertilizer field experiments of brassica napus crops based on the "3414" regression optimum design principle.[Result]The optimal fertilization amount of brassica napus by"3414" test was N 131.70-399.90 kg/hm2, P2O5 47.85-326.85 kg/hm2, K2O 77.55-320.25 kg/hm2.[Conclusion]Combining with the local reality,the recommended fertilization amount of rape is N 180-360 kg/hm2, P2O5 120~150 kg/hm2, K2O 150-180 kg/hm2.
