【摘要】 [目的]探讨生物有机肥的特点及在桃树上的应用效果。[方法]通过在辽宁省主要果产区开展生物有机肥施用示范试验,探讨生物有机肥对桃树生长及试验地土壤的影响。[结果]施用生物有机肥后桃树产量和果实品质都比常规施肥有所提高,其中产量与对照相比增加16.4%,果实的维生素C及总糖含量也明显提高;施用生物有机肥提高了土壤中全氮、速效磷、有效钾和有机质含量,降低了土壤的容重。[结论]生物有机肥可明显改善果实产量和品质,同时可改良果园土壤,保护环境,在绿色果品生产中具有广阔的应用前景。更多还原

【Abstract】 [Objective] This study aimed to investigate the characteristics of bio-organic fertilizer and its effect when applied to peach.[Method] Through launching demonstration trial on the application of bio-organic fertilizer in the major fruit producing areas in Liaoning Province,the effects of bio-organic fertilizer on peach growth and soil were investigated.[Results] After application of bio-organic fertilizer,both the peach yield and fruit quality were improved to some extent,of which yields was increased by 16.4% compared with the control,and vitamin C and total sugar contents were also significantly increased;application of bio-organic fertilizer also improved the contents of total nitrogen,rapidly available phosphorus,available potassium and organic matter in soil,and reduced the soil volume weight.[Conclusion] Bioorganic fertilizer can significantly improve fruit yield and quality,as well as improving orchard soil and protecting the environment,thus possessing a bright application prospect in the production of green fruits.更多还原
