[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。
[Objective] The research aimed to discuss the characteristics of bio-organic fertilizer and the application effect on peach trees. [Method] Through the demonstration experiment of bio-organic fertilizer application in the main fruit producing areas in Liaoning Province, the effects of bio-organic fertilizer on the growth of peach trees and the soil in the experimental area were discussed. [Result] Compared with the conventional fertilization, peach yield and fruit quality increased after applying organic manure. The yield increased 16.4% compared with the control, and the content of vitamin C and total sugar in the fruit also increased obviously. The application of bio-organic fertilizer increased Soil total nitrogen, available phosphorus, available potassium and organic matter content, reducing the soil bulk density. [Conclusion] Bio-organic fertilizer could obviously improve the yield and quality of fruit, at the same time improve the orchard soil and protect the environment, which has broad application prospects in the production of green fruit.
