摘  要：
为增强含磷复合肥在红壤上施用的肥效,提高磷肥利用效率。通过田间小区试验,研究不同添加剂(增效剂和控失剂)对磷酸铵镁和磷酸二铵肥效的影响。结果表明:在相同养分投入下,磷酸铵镁添加增效剂和控失剂对玉米产量和收获指数影响不显著;但添加增效剂后降低了玉米对N、P、K吸收,较对照磷素生产效率提高28.5%,对磷肥的偏生产力没有显著影响;添加控失剂增加玉米N、P、K吸收,降低玉米磷素生产效率和偏生产力。磷酸二铵添加增效剂能提高玉米产量和收获指数,降低玉米对N、P、K养分的吸收,但较对照磷素生产效率提高24.8%,偏生产力提高1.5%。

摘  要：
In order to enhance the fertilizer efficiency and the utilization efficiency of phosphate on phosphorus compound fertilizer application in red soil,a field plot experiment was conducted to study the influence of additives(Synergist and controlied release formulation)on fertilizer effects of magnesium ammonium phosphate and diammonium phosphate.Results:Magnesium ammonium phosphate added synergist and controlled release formulation had no significant effects on maize yield and harvest index.However,increased maize yield and harvest index compared with CK addition of magresium ammonium phosphate and diammoniun phosphate and Absorption of N,P,K were reduced but addition of synergist raised the physiological utilization ratio and partial fertilizer productivity of diammonium phosphate fertilizer with corresponding values of 24.8% and 1.5%,respectively.Magnesium ammonium phosphate added synergist decreased the absorption of N,P,K in maize,increased physiological utilization ratio of phosphate fertilizer by 28.5%,and had no significant influence on partial productivity.Controlled release formulation increased absorption of N,P,K nutrient,and reduced the phosphate fertilizer physiological utilization of maize and partial productivity.
