摘要
土壤有机质是土壤基础肥力和生产力的重要指标,提高果园土壤有机质含量是提高果园土壤肥力的关键,也是生产优质无公害和有机果品的基本条件与保障。在我国,果园土壤有机质含量普遍偏低,平均含量不到10g/kg。因此,为了更好地提高果园土壤肥力、果实产量及品质,现综述了影响我国果园土壤有机质含量的因素,分析了造成土壤有机质含量偏低的原因,总结了提升果园土壤有机质的途径,并介绍了新兴果园土壤肥力管理模式——果园生草对土壤有机质的影响及其研究进展,以期为我国果园的可持续健康发展提供参考依据。
The organic matter of the soil is the inaportant indicator of the basic soil fertility and the orchard productivity. It was the key factor to improve the soil fertility in the orchard,and also the basic requirement and guarantee to produce the pollution-free and organic fruit. In China,the organic matter content in the soil of the orchard was generally low. It was no more than 10 g/kg in the most orchards. Therefore,in order to improve the soil fertility of the orchard,and the yield and quality of the fruit, we summarized the factors which effected the organic content,analyzed the reasons which made it lower,put up the measures to improve it, and especially presented the effects of the new management model of the orchard,the sod cultivation in orchard,on the soil organic matter and its research progress. Hopefully, it could provide .some evidences for the sustainable and healthy development of the orchard.
