果园废弃物生物质炭在果园中应用效果的研究进展

处理果园废弃物是果园生产中的重要环节，传统方式主要有填埋、饲料、焚化、堆肥、厌氧消化、酶利用等。果园废弃物生物质炭是以果园生产中的废弃物为原料，通过热解技术转化后获得生物质炭。将生物质炭返还于果园，这样不仅改良了果园土壤，还保障和提高了果实产量和品质。果园废弃物在果园中的合理应用对果园生产效率和生态环境具有重要的稳定作用，开展果园废弃物生物质炭的研究对其在果园中的合理应用和演变机质具有重要的科学意义和应用价值。目前，果园废弃物生物质炭的研究集中于不同类别果园废弃物生物质炭的制备原理和性质，改良土壤的效果以及有机肥配施对果园生产的影响。未来应重点关注:①进一步分类果园废弃物，制备更多满足差异化需求的生物质炭；②比较不同类别果园废弃物生物质炭施用的生产效益；③制备果园专用生物质炭基有机肥；④探讨果园废弃物生物质炭对果园生态环境的影响。图1表2参94

Research progress on application effect of orchard waste biochar in orchard

Treatment of orchard waste is an important link in orchard production. The carbonization of orchard waste is a green, environmentally friendly and low-carbon mode of production, which can improve orchard soil, as well as yield and quality of fruits. Therefore, it’s of great scientific significance and application value to carry out research on orchard waste biochar for its rational application and evolution in orchard. The current research on biochar from orchard wastes was reviewed, which mainly focused on the preparation principle and properties of biochar from different types of orchard wastes and the effects on soil improvement, and the impact of its application combined with organic fertilizer on orchard production. The future research directions are proposed: (1) To further classify the orchard wastes to prepare more biochar to meet the differentiated needs. (2) To compare the production benefits of different types of orchard waste biochar application. (3) To prepare biochar-based organic fertilizer for orchard. (4) To explore the effect of orchard waste biochar on orchard environment and ecology. Ch, 1 fig. 2 tab. 94 ref.]
