CCTV News:The Ministry of Agriculture and Rural Affairs released it on January 29th. As a major measure to promote the green development of agriculture, the pilot project of green farming and recycling agriculture started in 2021 has achieved initial results. Green planting and recycling agriculture will be piloted, and manure will be returned to the field nearby to maximize the utilization of resources.
In the three years since the pilot project of green farming and recycling agriculture was launched, the central government has allocated a total of 7.402 billion yuan. It will be promoted in 299 counties in major animal husbandry provinces, major grain and vegetable producing areas and key ecological protection areas. Support specialized service organizations to provide services for the collection, treatment and application of manure, drive livestock manure in the county to return to the fields nearby, promote the reduction of chemical fertilizers, and promote the quality improvement of cultivated land and the green development of agriculture.
Li Zengyu, deputy director of the Planting Management Department of the Ministry of Agriculture and Rural Affairs, said that since the pilot project of green planting and breeding circular agriculture was launched, a number of service organizations have been cultivated and expanded, and a number of technical models have been integrated and promoted, which has explored experience for the subsequent promotion of green planting and breeding circular agriculture. In 2024, the Ministry of Agriculture and Rural Affairs, together with the Ministry of Finance, will carry out the pilot project of green farming and recycling agriculture.
"Turning waste into treasure" from livestock manure to increase production, improve quality and increase efficiency
In China, the large amount of livestock and poultry waste and the low degree of resource utilization have always been one of the important reasons for rural non-point source pollution. What changes have taken place in the agricultural production in the pilot counties since the pilot project of green farming and recycling agriculture was launched?
Near the Spring Festival, the strawberry planting base in Shucheng, Anhui Province ushered in a bumper harvest season. Growers told reporters that their strawberries have grown well and sold well in the past two years.
In 2021, as one of the first pilot projects of green farming and recycling agriculture in China, Shucheng, Anhui Province promoted the resource utilization of livestock and poultry manure in rural areas, and produced solid organic fertilizer to be returned to the field through collection and fermentation.
In Cheng Feng’s 120-acre strawberry greenhouse, the organic fertilizer pipeline was also connected. Liquid organic fertilizer is evenly delivered to strawberry roots, which not only grows better and tastes better than before, but also greatly reduces the cost.
The reporter learned that in order to reduce agricultural non-point source pollution, Shucheng subsidized 200 yuan per ton of fertilizer for growers who participated in the green planting and breeding cycle. In 2023, the county’s pilot area reached 100,000 mu, covering a variety of industries such as grain, fruits, vegetables, tea and Chinese herbal medicines, and digested 300,000 tons of livestock manure from more than 100 farms.
The reporter learned that in order to promote the smooth implementation of the green breeding cycle, Shucheng also tests more than 60 batches of organic fertilizers for heavy metal residues and microbial content every year.
Explore a variety of technical models of organic fertilizer "point manure into gold"
Carry out pilot projects of green farming and recycling agriculture to provide experience for large-scale popularization and application. What good practices have been explored in the pilot counties?
These days, in Anjiazhuang Town, Feicheng, Shandong Province, Jing Haijun, a large grain grower, is topdressing more than 3,000 mu of wheat. Different from previous years, in the past two years, he used nano-film to cover the organic fertilizer fermented by the new technology of composting and returning to the field.
The reporter learned that the scale of crop planting and livestock and poultry breeding in Feicheng, Shandong Province is relatively large, with an annual straw output of more than 700,000 tons and a livestock manure output of more than 800,000 tons. In order to make full use of these resources, Feicheng explored a variety of extension models of manure returning technology in the pilot project of green planting and recycling agriculture.
In addition to the new technology used by Jing Haijun, a large grain grower, there is also a biogas fermentation technology model.
The reporter in Hutun Town, Feicheng saw that the earthworm biodegradation model was adopted here. By using advanced culture technology and the principle that earthworms take solid organic wastes as food, the pollution-free, zero-emission and harmless biotransformation of solid organic wastes such as livestock manure, crop straws and rotten vegetable tail leaves is realized.
The reporter learned that while exploring effective technology models, Feicheng also encouraged enterprises, cooperatives and other market players to carry out manure collection, treatment and application services through policy support, and cultivated a number of professional service organizations, and the market scale continued to expand.
In China, since the pilot project of green planting and recycling agriculture was launched, 10 typical technical models of returning manure to fields have been summarized and refined, with a cumulative application area of more than 61.4 million mu. At the same time, more than 2,500 service organizations for returning manure to fields have been developed, and 890,000 planting and breeding subjects have been connected.
