Research On The Pollution Control Of Livestock And Poultry Manure

China is a great agricultural nation.Breeding industry is not only an important part of agriculture,but also belongs to Chinese traditional advantage industry.The production mode of breeding industry in China gradually changed from retail investors to intensification,and then to scale farming.According to the International Meat Organization,China’s livestock and poultry meat production accounts for 29% of the world’s total production,ranking first in the world for 21 consecutive years.However,with the expansion of the scale of breeding,the large amount of livestock and poultry manure produced by the breeding industry has caused serious damage to the ecological environment and is also one of the main sources of agricultural non-point source pollution.According to the statistics of the Ministry of Agriculture and Rural Affairs in 2016,the annual livestock and poultry manure produced in China has reached 3.8 billion tons,but the scientific treatment rate is less than 60%.A large amount of livestock and poultry manure is randomly discharged and accumulated,causing different degrees of pollution to air,water and soil.The destruction of the ecological environment will ultimately affect the life and production of human beings.The pollution of livestock and poultry farming has attracted the attention of the state and local governments.However,Chinese livestock and poultry manure pollution control work started late with less experience.Livestock and poultry manure pollution control has many problems in China.Chinese breeding industry has large regional differences,so we need concrete analysis of concrete problems.Based on the above background,this article takes Qionglai city of Sichuan province as the research object and builds on the basis of field investigation.This paper conducts semi-structured interviews with Qionglai farmers and the Agriculture and Forestry Bureau to obtain relevant data.All the information and data of livestock and poultry manure governance in Qionglai city were obtained.With the help of the four elements analysis framework of new structural economics,and from Qionglai resource endowments and comparative advantage,this paper analyzes the Qionglai city waste recycling use of the specific patterns and their waste resource utilization industry manure cost benefit and the government as the market main body,discusses the efficient market and for the role of government in waste management,summarized takes the path of livestock and poultry breeding waste management.The studies have shown : First,the long-distance recycling pattern adopted by qionglai city has effectively controlled dung pollution of livestock and poultry breeding,and achieved environmental,economic and social benefits.Second,the effective effect of the dung treatment market and the effective government in the breeding waste pollution treatment are the key to success of the remote recycling model of dung in Qionglai city.Third,comparative advantage is the prerequisite for the poultry manure resource utilization industry in Qionglai city.The effect of market mechanism is the key for the formation and development of fouling resource utilization industry in Qionglai city.The guidance of the government has promoted the development and growth of the dung poultry manure resource utilization industry in Qionglai city.Fourth,the treatment of livestock and poultry manure pollution in qionglai city follows the path of selecting the best treatment method according to the resource endowment structure and comparative advantages under the joint action of effective market and effective government.Aiming at the problems encountered in the abatement of manure in livestock and poultry breeding in Qionglai City,this paper proposes the following policy recommendations: The first,make unified manure quality standard and improve manure pollution control level.Second,formulate subsidy standards flexibly and simplify examination and approval procedures.Third,construct manure storage tanks in cooperatives to improve the capacity of manure storage.
