Xi'an plans to achieve a comprehensive utilization rate of straw of 20% in 2018

[ China Agricultural Machinery Industry News ] Incineration of straw is more harmful, such as: causing serious air pollution, causing traffic accidents, affecting road traffic and aviation safety, causing fires, destroying soil structure, causing decline in farmland quality... Incineration of straw also causes fog One of the culprit's culprit. At present, Xi'an is accelerating the comprehensive utilization of straw and eliminating the air pollution caused by straw burning.

Xi'an plans to achieve a comprehensive utilization rate of straw of 20% in 2018

By the end of 2017, the comprehensive utilization rate of straw will remain above 90%, and open burning will be effectively controlled. By 2018, the comprehensive utilization rate of straw will reach 95%.

The comprehensive utilization pattern of biomass will be formed in 2020

Almost every year in the wheat harvest season, there will be reports of smog in the country due to burning straw, and the city becomes a report of “fog capital”. Due to strict management and control, Xi'an has achieved “zero fire point” in the wheat harvest season for many years. However, it is not easy to maintain such a result. Xi’an relied on the “wheel battle” that was strictly guarded against death. This kind of combat mode was slightly inattentive and burned. Straw may rebound.

It is understood that Xi'an will aim to eliminate straw burning this year, and mainly rely on straw machinery to return to the field, and continuously expand multi-channel comprehensive utilization. By the end of 2017, the comprehensive utilization rate of straw will remain above 90%, and open burning will be effectively controlled. By 2018, the comprehensive utilization rate of straw will reach 95%, and the straw storage and storage system will be basically formed. The straw and fruit branches will be cleaned and warmed, the comprehensive utilization methods of straw and fruit bead feed and base material will be expanded, and open burning will be basically eliminated. significantly reduce. By 2020, a comprehensive layout of biomass such as straw with reasonable layout and diversification will be formed. The comprehensive utilization rate of straw will be stable at over 96%, and the biomass burning pollution situation will be significantly improved.

Promote the mechanization of straw to return to the field, and provide fixed subsidies to farmers who implement mechanized returning of straw, such as mechanical smashing, breaking, and deep ploughing. In 2017, the mechanized return of the main crop straws was stable at more than 85%. Among them, Lantian County, Zhouzhi County, Hu County, and Chang'an District have reached more than 85%, and other districts, counties and development zones have reached more than 90%.

Xi'an City will be built of straw biogas demonstration projects

The city will implement clean energy utilization of straw, and actively investigate new technologies for energy utilization of straw solidification, biogasification, pyrolysis gasification, carbonization, etc., publicize and guide agricultural parks, enterprises to introduce new technologies, conduct technical tests, and support materials. Shed, finished product warehouse, purchase of curing molding equipment and other projects.

It will provide certain subsidies for the use of solid-formed multi-fuel plumbing stoves such as straw and fruit branches, to achieve low-emission burning and clean heating of straw and fruit branches. Actively inspect the hydrothermal liquefaction straw to produce biofuels, chemicals and activated carbon materials and other integrated comprehensive utilization technologies, and carry out straw biogas project pilots to realize direct supply of straw biogas to farmers. Encourage coal-fired power plants to implement straw blending projects.

Through the above measures, we will strive to achieve breakthroughs in the clean energy utilization of straw in 2017, and construct a straw biogas demonstration project in the towns of Huxian County and Lantian County. In 2018, the utilization rate of straw energy cleaning reached more than 5%, of which Huxian County and Lantian County reached more than 6%, and other districts and counties and development zones reached more than 5%.

Forming a straw material utilization utilization mode with regional characteristics

Xi'an will promote the utilization of straw raw materials, cultivate leading enterprises, and demonstrate the specialization, scale and industrialization of straw raw materials utilization. Supporting the use of straw as raw material to produce packaging materials, wall materials, degradable films, artificial boards, composite materials, fertilizers and other products. The municipal department is responsible for inspecting new technologies and introducing investors. The district and county governments are responsible for conducting negotiations and cooperation according to local conditions, and forming a straw raw material utilization model with regional characteristics. In 2017-2018, we will strive to industrialize straw raw materials and realize one county and one product. The relevant districts and counties will build a demonstration site for straw raw material utilization, and continuously improve the utilization level of straw high value.

Establish a straw storage and storage service system, and encourage enterprises to carry out specialized storage and storage services and improve the service level of straw storage and transportation according to the principles of government promotion, market operation, enterprise lead, and farmers' participation. It is planned to build a straw storage and storage base, and form a straw storage and utilization system for the village's storage and storage station, the town's storage and storage center, and the county's large-scale utilization enterprise.

Before the end of November this year, in accordance with the requirements of the village's storage and storage station, the town's storage and storage center, and the county's large-scale utilization enterprises, Yanqiao District, Yanliang District, Linyi District, Chang'an District, Gaoling District, Hu County, Lantian County, A pilot demonstration project of full utilization of straw was built in 8 agriculture-related counties and counties such as Zhouzhi County.
