研究不同树盘覆盖方法对早酥梨园土壤肥力和树体生产性状的影响。结果表明,生物菌肥+秸秆覆盖、秸秆+地膜覆盖显著提高了梨果实品质和产量,梨园土壤的有机质含量、碱解氮、速效磷和速效钾含量显著增加,树体干周和冠径明显提高,单纯秸秆覆盖效果比前二者稍差;由此可见,采用秸秆覆盖是现代梨园土壤管理制度的有效途径之一,添加生物菌肥和加盖地膜可以显著提高秸秆的转化效率和增产潜力。 The effects of different tree cover methods on soil fertility and tree productive traits in asiatic pear were studied. The results showed that the bio-microbial fertilizer + straw mulching and straw mulching significantly increased the fruit quality and yield of pear. The content of organic matter, available nitrogen, available phosphorus and available potassium in pear soil increased significantly, Therefore, using straw mulch is one of the effective ways to modernize soil management system of pear orchards. Adding bio-fertilizer and mulching film can significantly increase the conversion efficiency and yield potential of straw .
