The carbonization of crop stalks and soil improvement projects focus on soil cultivation and improvement, and carry out the large-scale utilization of crop stalk resources. Create a high-quality ecological agriculture industrial chain. Most of the poor in my country are in remote rural areas, and the straw resources are relatively abundant, suitable for crop straw charcoal For the development of the soil improvement industry, the project can provide poverty-stricken households with various income-increasing channels to help alleviate poverty. Crop straw charcoal The soil improvement project has unique advantages and characteristics in industrial poverty alleviation, and can become a preferred industry for precise poverty alleviation. Carrying out crop straw carbonization and soil improvement projects in poor areas according to local conditions is in line with the targeted poverty alleviation and targeted poverty alleviation strategy, but also It is in line with the national policy of banning straw burning and comprehensive utilization; it not only realizes the sustainable development of agriculture, but also promotes the stable income growth of the poor Close. Through the carbonization of crop stalks, the soil improvement industry chain can form an effective poverty-removing mechanism, and achieve precise poverty alleviation and ecological agriculture in poor counties. The dual effect of industry development. In order to standardize the operation of the industry in poverty alleviation projects, instruct local poverty alleviation organizations to carbonize crop straw and return soil For the implementation of improvement projects, this guiding technical document is specially formulated. Crop straw carbonization and soil improvement project Operation Management Standard

1 Scope

GB/Z 39121-2020 is the Chinese national standard on specification for operation management of biochar production from crop staw on soil quality improvement project, in the field of services and company organization. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 11 October 2020 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 03.100, CCS A00. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This guiding technical document gives the project overview, project conditions, division of responsibilities, and projects of the crop straw carbonization and soil improvement project. Project organization and operation, project expected effect analysis and project evaluation and management. This guiding technical document is applicable to the operation and management of the soil improvement project of carbonization of crop stalks.

2 Project overview

Taking the biochar-based fertilizer plant project in a poverty-stricken county as a platform, a standard production capacity of 50,000 tons/year to 100,000 tons/year will be built in a poor county The biochar-based fertilizer plant in China will support the construction of 10-20 10,000-ton/year straw pelletizing poverty alleviation workshops. Poverty alleviation organizations, biochar-based fertilizer plants, The straw pelletizing workshop and poor households are "four in one", forming a straw utilization poverty alleviation industrial chain with a poverty-stricken mechanism. Embed poverty alleviation precisely in the cycle Economic industry chain, through biochar-based fertilizers to increase production and reduce expenditures, poverty alleviation, employment poverty alleviation, donation poverty alleviation, and straw pelleting poverty alleviation workshop Poverty alleviation through asset-based income and auxiliary poverty alleviation in related industries such as transportation to achieve industrial precision poverty alleviation. For typical cases of project poverty alleviation, see Appendix A.

3 Project conditions
