作物残体应用性及稳定性的研究进展

Crop Residue Application and Stabilization in Soil:A Review

农业生产会产生大量的作物残体。对作物残体的安全利用与处理已经成为全社会十分关注的重要问题。作物残体作为土壤养分的重要来源,其在土壤中的稳定与转化对于增加其养分持续时间、提高土壤肥力具有非常重要的意义。论文介绍了作物残体均匀深还及堆肥等提高作物残体稳定性的技术,简述了促进有机物质稳定与转化的新方法,总结了不同作物残体处理方式对土壤性质的影响。以期为作物残体的高效合理利用提供参考依据。

Agricultural activities produce vast amounts of crop residue. The safe utilization of crop residue has become an important issue. Since crop residue is as an important source of soil nutrients, its stabilization and transformation played an important role for improving soil fertility and increasing the duration of crop residue nutrients. This paper introduced the techniques for improving the stabilization of crop residue such as deep and uniform straw returning and composting, summarized the new methods for promoting the stabilization and transformation of organic matter, and reviewed the effects of different crop residue treatment methods on soil properties. The ultimate goal of this paper would provide reference for the efficient and reasonable utilization of crop residue.
