保护性耕作对吉林省农田土壤有机碳含量和储量的影响
Effects of conservation tillage on soil organic carbon content and stock in farmland of Jilin Province
摘要
Abstract
To explore the mechanisms and driving factors underlying the effects of conservation tillage on soil organic carbon(SOC)in farmland soils in Jilin Province,this study employed a Meta-analysis method to quantitatively investigate the effects of conservation tillage on SOC content and stock in Jilin Province farmland,as well as the influencing factors.The results of the study shown that:compared with traditional tillage,conservation tillage significantly increased SOC content and stock(P＜0.05),but the effectiveness decreased with increasing soil depth.The amount of crop residue retention was the primary influencing factor for the promotion of SOC content and stock under conservation tillage.As the amount of crop residue retention increases,the positive effects on SOC content and stock were significantly enhanced(P＜0.05).Conservation tillage at different cultivation periods significantly increased SOC content and stock,with the most pronounced effects observed when the cultivation period ≥10 years.The optimal SOC content and stock were achieved when nitrogen application was in the range of ≤100 kg·hm-2,phosphorus application was ≥100 kg·hm-2,and potassium application was＞80 kg·hm-2.In conclusion,the implementation of conservation tillage can significantly enhance the carbon sequestration capacity of farmland soils in Jilin Province,providing critical support for regional agricultural sustainable development.关键词
