山东省临沂市粮食作物秸秆还田化肥减施和温室气体减排潜力估算
Fertilizer Reduction Potential and Greenhouse Gas Emission Reduction Potential under Grain Crops Straw Return in Linyi,Shandong Province
摘要
Abstract
To estimate the contribution of the total amount of straw returning to the field of major grain crops in Linyi of Shandong to soil nutrient input and greenhouse gas N2O emission reduction,based on statistical yearbook data and literature research data,the grass to valley ratio method was used to estimate the potential for reducing fertilizer application and greenhouse gas emissions of straw returning to the field of grain crops in Linyi.In the scenario of fully returning straw to the field,the nutrient inputs of wheat straw were N 24.11-30.56,P2O5 8.41-10.66,and K2O 83.75-106.17 kg·hm-2,respectively.The nutrient inputs of corn straw return were N 47.03-63.39,P2O5 23.73-31.98 and K2O 114.04-153.70 kg·hm-2,respectively.The nutrient inputs of rice straw return were N 30.09-38.25,P2O5 13.91-17.68 and K2O 136.06-172.97 kg·hm-2,respectively.The total nitrogen(N)nutrient release of wheat,corn,and rice straw returning to the field in the current season is 7 900 tons,13 600 tons,and 1 400 tons,respectively,which can reduce N2O emissions by 155.25 tons,268.57 tons,and 27.64 tons,respectively.In summary,returning straw to the field is of great signifi-cance for reducing fertilizer application and greenhouse gas emissions.关键词
