Jiangsu Shanyang: Open a new model of green seed recuperation cycle

The livestock and poultry manure of each household is collected one by one, and it is uniformly transported to the livestock and poultry manure treatment center in Hede Town in Couplet Gengtang Village. , Processing into a biochastic liquid and biological fertilizer. It can not only ensure the long -term development of the local livestock and poultry breeding industry, but also improve the surrounding living environment. This is the process of promoting green breeding in Cantintang Village, Yedang County, Yanyang County, Yanyang County, Jiangsu Province.

As a large agricultural county and aquaculture county, Jingsheng has a cultivated land of 2.08 million mu, 1.15 million pig breeding, 28 million poultry breeding, and has also been awarded "National Pigs to Da County". The prosperity of the grains and the six beasts have always been a beautiful vision in people's hearts, but in the face of such a huge scale of breeding, environmental problems such as agricultural surface source pollution have also increased day by day. In 2021, the county's total annual livestock and poultry feces were 1.56 million tons. Among them, the production of livestock and poultry feces in large -scale farms is 1.1 million tons, and the amount of livestock and poultry manure in breeding farms below the scale is 460,000 tons.

Promoting carbon peaks and carbon neutrality in the agricultural and rural areas is an important part of accelerating the construction of agricultural ecological civilization, and an important measure to implement the strategy of rural revitalization. In recent years, Zeyang County has regarded the pilot work of green breeding circular agriculture as a realistic needs for promoting the high -quality development of animal husbandry and planting industries. With the opportunity of the construction of pilot projects in the country, it has established a technical cooperation alliance with the Jiangsu Academy of Agricultural Sciences to promote green green The in -depth development of breeding and recycling agriculture has improved the quality of superior agricultural products, and promoting the high -quality development of green agriculture. On June 21, the Pilot Promotion Conference on the Green Seed Circle Circle Agricultural Pilot Work in Jiangsu Province was successfully held in Sheyang County in 2022.

The utilization of livestock and poultry manure resources is an important starting point for realizing the green development of animal husbandry, which is of great significance for achieving the sustainable development of animal husbandry, ensuring the safety of ecological environment and the safety of animal products. Recently, the "Key Mission of Ecological Environmental Protection During the" Fourteenth Five -Year Period "period in Zhanyang County" also pointed out that during the "Fourteenth Five -Year Plan" period, it will explore the development of a low -carbon green economy and comprehensively integrate the "dual carbon" goal into the shot. The economic and social development layout of Yang County has created a veritable "double carbon county". The document also specifically mentioned that "controlling the agricultural field emissions, the implementation of agricultural green development actions, promoting agricultural circulation production methods, and supporting the use of livestock and poultry stools to develop biogas projects for raw materials, controlling livestock and poultry breeding methane and nitrous oxide."

"We first formulate implementation plans, and publicly select 13 production bases, concentrated stacks, transportation and distribution, and mechanical return to the field of manure, and select 445 production bases with good working foundations and strong demonstration capabilities, large planting households, and large -scale planting households, large planting households,, large planting households, large planting households, large planting households, and planting households, large planting households, and large planting households, large planting households, and large planting households, large planting households, and large planting households, large planting households, and large planting households, large planting households, and large planting households, large planting households, and large -scale planting households, large planting households, and large -scale planting households, large planting households, and large planting households, and large planting households. Family farm, as the main body of green breeding recycling cycle. "Qiao Qianqun, director of Zhenyang Agricultural and Rural Bureau, introduced that at the beginning of this work, he took the lead in selecting the application subject and implemented the green seed recycling agricultural agriculture mainly rice, wheat, and vegetables. 102,000 mu, formulated the "Social Service Organization Measures for Green Seeding Circle Circle Circle Agricultural Pilot County in Green Seeds in Shanyang County", established green breeding circulating agricultural manure flow towards traceability system, and promoted the healthy operation of service organizations.

Jingsheng Energy Co., Ltd., located in Jingsang Port Economic Development Zone, is a typical example of Jingsang County's focus on creating green circulating agriculture. The company has cooperated with Guangming Dairy for a long time to harmly treats the manure generated by the company's pasture through a pipeline, and then forms biogas and biogas. After the biogas purification is purified, the natural gas supplies the CNG gas station and industrial users within the county area. The biogas liquid is used as high -quality fertilizer to improve the soil structure to facilitate grain planting, and the planting barley can be used as a feed of dairy. Let the "resource in the wrong position" return to position, and at the same time generate economic benefits. The person in charge of Jinyuan Company introduced: "These manure can produce about 12,000 cubic meters of biogas daily, and it is purely 7,000 cubic meters of biological natural gas. This annual sales of more than 8 million yuan!"

Based on the "Fat and Water Returning Field" system proposed by the Chinese Academy of Sciences, Shijiayang actively adopted the three services of "treatment center+agricultural park+growers", "processing center+village party branch+production base+farmers", "processing center+cooperative+production base" Model, "uniformly collect, concentrate fermentation, targeted distribution, mechanical application", and promote the use of manure to return to the field. In rice, wheat and other grain crops, promote the "biogas, rotten manure+recipe fertilizer" model, and promote "organic fertilizer+formula fertilizer" and "organic fertilizer+water fertilizer integration" model in the centralized production area of ​​vegetables and fruit trees. At present, the 13 livestock and poultry manure treatment centers of Sheyang County have collected 530,000 tons of annual collection, 20,000 tons of organic fertilizer, 45,000 tons of rotten manure, 450,000 cubic meters of biogas, and 5,000 acres of daily fields.

Speaking of the future development, Qiao Qianqun is full of confidence: "In the next step, Jingsang County will focus on the goal of the green planting cycle agricultural area of ​​100,000 acres and the comprehensive utilization rate of livestock and poultry manure of more than 98%. Improve the high -quality service mechanism, integrate technology leading mechanism, optimize normal supervision mechanisms, improve long -term operating mechanisms, and promote the pilot work of green breeding recycling agriculture in depth.
