摘　　要：整地机械在农业生产中发挥着重要作用,可以改善土壤的物理性质,促进土壤微生物活性,提高土壤有机质含量,从而增加土壤对碳的储存能力。以旋耕机为例开展分析,选取工作深度、速度、转速为影响因素,探明在不同参数下土壤对碳的储存能力,结合试验数据分析,探讨了这些参数对土壤固碳效果的影响程度。试验结果表明,适当调整整地机械的作业参数可以显著提高土壤固碳能力,其中工作深度和速度是影响固碳效果的关键参数之一,增加工作深度可以显著改善土壤的通透性和通气性,有利于微生物活动和有机质的分解,进而提高土壤的碳储存能力。然而,过深的工作深度可能会破坏土壤结构,降低固碳效果。研究结果对于优化农业生产方式、提高土壤碳储量具有一定的理论和实践意义。Land preparation machinery plays an important role in agricultural production,which can improve the physical properties of soil,promote soil microbial activities,and increase the content of soil organic matter,so as to increase the carbon storage capacity of soil.Taking rotary tiller as an example to carry out the analysis,the working depth,speed and rotational speed were selected as the influencing factors to explore the storage capacity of soil carbon under different parameters,and the degree of influence of these parameters on the effect of soil carbon sequestration was discussed in combination with the analysis of experimental data.The experimental results show that appropriate adjustment of the operating parameters of land preparation machinery can significantly improve the soil carbon sequestration capacity,of which the working depth and speed are one of the key parameters affecting the effect of carbon sequestration,and increasing the working depth can significantly improve the soil permeability and aeration,which is conducive to the microbial activity and decomposition of organic matter,and thus improve the soil carbon storage capacity.However,too deep a working depth may damage the soil structure and reduce the carbon sequestration effect.This study has certain theoretical and practical significance for optimising agricultural production methods and increasing soil carbon storage.
