| 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. |
