本发明公开了种恢复热脱附后土壤耕作性的方法，该方法的步骤是：1)利用热脱附系统产生的低温余热预热流态畜禽粪便；2)将热预后的流态畜禽粪便加入到经热脱附处理后的土壤中，混合均匀，得混合土壤体系A，将混合土壤体系A保温灭菌30-60min，得无菌混合土壤；3)利用无菌混合土壤余热预热下批待处理的流态畜禽粪便；4)向自然冷却后的无菌混合土壤中加入水、秸秆粉末、复合微生物菌剂，搅拌均匀，得混合土壤体系B，将混合土壤体系B堆置，常温下发酵7-15天。该方法简单，成本低，能快速提高热脱附后土壤中的有机质含量、氮磷含量和含水率，恢复热脱附后土壤的肥力和含水量，从而恢复热脱附后土壤的耕作性。 The invention discloses a method for recovering tilth of soil after thermal desorption. The method comprises the following steps: 1) preheating flow-state livestock and poultry manures by utilizing low-temperature waste heat generated by a thermal desorption system; 2) adding the preheated flow-state livestock and poultry manures into the soil treated by thermal desorption, carrying out uniform mixing so as to obtain a mixed soil system A, and subjecting the mixed soil system A to heat-preserving and sterilization for 30 to 60 min so as to obtain aseptic mixed soil; 3) preheating a next batch of to-be-treated flow-state livestock and poultry manures by utilizing waste heat of the aseptic mixed soil; and 4) adding water, st
