种养结合对肉羊养殖减排增效的影响OACSTPCD

Aiming at whether the combined production mode of planting and breeding can effectively promote the emission reduction and efficiency of mutton sheep breeding,the Super-SBM model and treatment effect model are used to study the impact and influencing mechanism of planting and breeding combination on environmental technical efficiency of mutton sheep breeding.The results show that:On one hand,compared with non-combination of planting and breeding,the combination of planting and breeding can improve environmental technical efficiency of mutton sheep breeding.Compared with non-combination of planting and breeding mode,the higher degree of combination of planting and breeding mode is more effective in improving the environmental technical efficiency of mutton sheep breeding.On the other hand,the combination of planting and breeding can improve the environmental technical efficiency of mutton sheep breeding by reducing forage input,increasing live weight of mutton sheep and reducing carbon emissions.In conclusion,some policy suggestions,such as strengthening research and promotion of combination of planting and breeding technology,establishing the green oriented mechanism of aquaculture regulations and policies,and improving the level of regional cultivation,are put forward in this study.
