In 2017, the straw utilization poverty alleviation project was fully verified in Horqin Youqian Banner (Kerqin Youqian Banner for short), Inner Mongolia Autonomous Region. Keyouqian Banner was rated as a national-level poverty-stricken county in 2011. It is a concentrated and contiguous extremely poor area in the mountainous area at the southern foot of the Daxingan Mountains. The poor people are mainly concentrated in agriculture. There are 13,480 registered poor households with 29,392 people in the entire flag, covering 14 Sumu towns and 228 villages. The total area of arable land in the flag is 4.16 million acres, with 3.78 million acres of grain crops and a total straw volume of 1.26 million tons. Straw utilization is in the primary stage and the added value is low. The first phase of the Keyouqian Banner 50,000 tons/year biochar-based fertilizer plant project directly employs 150 registered poor people and employs more than 5,000 people temporarily. At the same time, biochar-based fertilizers can greatly improve the quality of agricultural products and hide wealth in the ground. A.2 Models and Practices A.2.1 Assistance Model A.2.1.1 Basic Idea Taking the establishment of biochar-based fertilizer plants in poverty-stricken counties as a platform, one poverty-stricken county will build a standard production capacity of 50,000 tons/year to 100,000 tons /year biochar-based fertilizer plant, supporting the construction of 10 to 20 10,000 tons/year straw granulation poverty alleviation workshops. Poverty alleviation organizations, biochar-based fertilizer plants, straw pelleting poverty alleviation workshops, and poor households are "four in one" to form a straw utilization poverty alleviation industry chain with a poverty alleviation mechanism. A.2.1.2 Basic approach: A 50,000 tons/year biochar-based fertilizer plant project has a project investment payback period of 7 to 8 years (including a construction period of 1 year) and a project rate of return of 10% to 12%. There are 10 poverty alleviation granulation workshops with a total investment of about 65 million yuan (including equipment), annual sales revenue of about 55 million yuan, and an average annual profit of 5 million yuan. The straw pelleting poverty alleviation workshop uses poverty alleviation funds, agriculture-related funds, agricultural machinery purchase subsidies and other funds to form fixed assets, and provides asset income to registered poor households in accordance with local poverty alleviation fund usage regulations. A.2.2 Specific assistance measures A.2.2.1 Pelletization workshop poverty alleviation model A.2.2.1.1 In the straw utilization poverty alleviation project, the granulation workshop is a key link and plays a connecting role. The granulation workshop is operated independently, and its functions include: the implementation of supporting policies, the implementation of poverty alleviation measures for biochar-based fertilizer plants, the farming and planting of registered poor households who lack labor ability or have only half labor ability, and the land of poor households. Collection, transportation and storage of straw, as well as distribution and promotion of biochar-based fertilizers. A.2.2.1.2 The granulation workshop has a designed annual production capacity of 10,000 tons/year. The infrastructure is constructed by poverty alleviation organizations. Equipment selection, procurement or equipment leasing is the responsibility of enterprises providing soil improvement technology for carbonizing crop straws and returning them to the field. It enjoys national and Local agricultural machinery purchase subsidies. The straw pelleting poverty alleviation workshop uses poverty alleviation funds, agriculture-related funds, agricultural machinery purchase subsidies and other funds to form fixed assets, and provides asset income to registered poor households in accordance with local poverty alleviation fund usage regulations. A.2.2.1.3 The biochar-based fertilizer factory purchases all straw particles from the granulation workshop at market prices to ensure the stable operation of the granulation workshop. The 7GB/Z39121-2020 capsule manufacturing workshop is independently operated, with an annual profit of 500,000 yuan to 1 million yuan. A.2.2.2 Poverty alleviation by using biochar-based fertilizers to increase production. When farmers use biochar-based fertilizers, their average income per mu of food crops increases by 201.9 yuan. A.2.2.3 Expenditure reduction and poverty alleviation using biochar-based fertilizers Biochar-based fertilizers have strong insect repellent and soil improvement effects. Annual expenditures on food crops can be reduced by 50 yuan per mu, of which pesticide expenditures are reduced by 20 yuan. Fertilizer expenditure is reduced by 30 yuan. A.2.2.4 Employment-based poverty alleviation The employment-based poverty alleviation project includes two links: a biochar-based fertilizer factory and a straw pelleting poverty alleviation workshop. It directly employs 150 registered poor people and employs more than 5,000 people in purchasing and storage. Among them: a) 10 granulation workshops, with a total number of workers of 50, and an average annual salary income of 20,000 to 30,000 yuan per person. b) Straw collection and storage employs 5,000 people. c) The biochar-based fertilizer factory employs 100 people for the poor and implements the five insurances and one housing fund system. The per capita annual wage income is 27,000 to 35,000 yuan; including 13 security and cleaning workers, with an average per capita annual income of 26,556 yuan. There are 33 employees in junior technical positions in the workshop, with an average annual income of 35,224 yuan per person. A.2.2.5 Asset Income Poverty Alleviation The straw pelleting poverty alleviation workshop will form fixed assets with a national purchase subsidy of 5 million yuan for the purchase, storage, transportation and granulation equipment, and provide asset income to registered poor households in accordance with local regulations on the use of poverty alleviation funds. income. A.2.2.6 Donation-based poverty alleviation: Public welfare funds will be extracted from the sales of biochar-based fertilizers (one yuan of public welfare funds will be extracted for every 40 kilogram bag of biochar-based fertilizer sold) as public welfare poverty alleviation funds.
