摘  要：
[目的]研究不同培肥模式对闽东茶园水土及其氮磷流失的影响,为该区茶园水土流失评价及防控提供科学依据。[方法]通过径流小区试验,设置6个处理:全量化肥(NPK),半量化肥+半量有机肥(1/2NPKOM),全量有机肥(OM),全量化肥+豆科绿肥(NPKL),半量化肥+半量有机肥+豆科绿肥(1/2NPKOM+L)和不施肥(CK)。[结果]不同培肥处理下径流流失量的大小顺序为:OM>1/2NPKOM>CK>NPKL>1/2NPKOM+L>NPK,泥沙流失量表现为:OM>1/2NPKOM>NPKL>CK>NPK>1/2NPKOM+L;OM处理中径流携带的全氮、可溶性氮、硝态氮、铵态氮、全磷、可溶性磷等氮磷组分的流失量均较高,而1/2NPKOM+L中这些氮磷组分流失量则相对较低,且泥沙结合态的全氮、全磷流失量在各处理中也有类似的变化规律。[结论]1/2NPKOM+L处理在减控茶园水土及其氮磷流失方面具有良好的保土保肥效果。

摘  要：
[Objective]The effect of fertilization patterns on losses of soil,water and nitrogen,phosphorus from tea garden in eastern Fujian Province was studied in order to provide a scientific basis for evaluation and prevention and control of soil and water loss in this region.[Methods]The experiment contained six treatments:no fertilization(CK),chemical fertilizers(NPK),half-organic manure plus half-chemical fertilizers(1/2NPKOM),organic manure(OM),legume stover returned plus chemical fertilizers(NPKL),half-organic manure plus legume stover returned plus half-chemical fertilizers(1/2NPKOM+L).[Results]Among all the treatments,water losses were ranked as OM>1/2NPKOM>NPKL>CK>NPK>1/2NPKOM+L,and soil losses followed the orders of OM>1/2NPKOM>NPKL>CK>NPK>1/2NPKOM+L.Furthermore,the OM treatment had maximum concentrations of soil nutrients including total N(TN),dissolved N(DN),NO3—N,NH+4—N,total P(TP)and dissolved P(DP)losses in runoff,while the 1/2NPKOM+L treatment had minimum concentrations of those nitrogen and phosphorus fractions compared to other fertilizer treatments.Similarly,the contents of TN,TP in sediment were the highest in OM treatment,but the lowest in 1/2NPKOM+L treatment.[Conclusion]The 1/2NPKOM+L treatment could be considered as a better choice of fertilization practice with respect to reducing soil,water,and nitrogen,phosphorus nutrient losses from tea soils in the region.
