摘　　要：以苹果(Malus pumila Mill.)为试验材料,以HPS生物有机肥为研究对象,设置2个HPS生物有机肥处理,施肥量分别为24、15 kg/株,并减施50%的化肥,同时以常规施肥管理为对照(CK),考察了HPS生物有机肥对苹果园土壤养分及苹果叶片养分和果实品质的影响。结果表明,与CK相比,2个HPS生物有机肥处理土壤养分含量、苹果叶片养分含量及果实品质均有提升,且以施用24 kg/株HPS生物有机肥处理最高,其土壤碱解氮、速效磷、速效钾含量及叶片全氮、全磷、全钾含量显著增加(P<0.05),果实单果重和纵径显著增加(P<0.05),可溶性固形物、可溶性糖含量和维生素C含量也显著增加(P<0.05)。这说明在化肥减施下施用HPS生物有机肥可提升土壤养分、叶片养分含量及果实品质,且以24 kg/株的施用量较佳。Taking apple(Malus pumila Mill.)as material and HPS bio-organic fertilizer as the research object,two treatments of HPS bio-organic fertilizer were set up,with application rates of 24 and 15 kg per plant,respectively,a 50%reduction in chemical fertiliz-er was conducted,and conventional fertilization was used as the control(CK).The effects of HPS bio-organic fertilizer on soil nutri-ents in apple orchard,apple leaf nutrients and fruit quality were investigated.The results showed that,compared to CK,the soil nutri-ent content,apple leaf nutrient content and fruit quality of the two HPS bio-organic fertilizer treatments were improved.The treatment with 24 kg per plant of HPS bio-organic fertilizer showed the highest improvements,with significantly increased levels of soil available nitrogen,soil available phosphorus,soil available potassium,leaf total nitrogen,leaf total phosphorus,leaf total potassium,single fruit weight and longitudinal diameter,soluble solids,soluble sugar content,and vitamin C content(P<0.05).This indicated that ap-plying HPS bio-organic fertilizer under reduced chemical fertilizer conditions could enhance soil nutrients,leaf nutrients,and fruit quality,with 24 kg per plant being the optimal application rate.
