The surplus of the economic forest has become a treasure on the spot

"In the cultivation of the tea seedlings, after we changed to a new formula developed by forestry waste, the categorian seedlings grew faster and stronger." Zhan Changsheng, chairman of Anhui Wanxiuyuan Ecological Agricultural Group Co., Ltd., said excitedly.

"The seedling matrix developed by the remaining objects such as camellia fruit shells can not only replace the peat matrix, but also the root effect is particularly good." He added.

This "new formula" is the technical achievement developed by the Chinese Academy of Forestry's wood oil breeding and cultivation team. The new recipe is made up after the surplus of the economic forests such as camellia and fruit shells for high temperature aerobic fermentation, dehydration, and sterilization. This result is reused through forestry waste resources, which effectively solves a large number of technical problems that can be handled by a large number of remaining forestry. At the same time, it improves the comprehensive efficiency of economic forests, realizes the recycling of resources, and effectively reduces carbon emissions.

Economic forest remains amazing

Through technological innovation and results transformation of scientific and technological personnel of the Institute of subtropical Forestry Research Institute of China Forestry Science Research Institute, realize the recycling of economic forest surplus objects, and build a comprehensive economic use system for high -value, low -carbon low -carbon low -consumption, to promote the use of resource recycling and industrial green low -carbon development Essence

Scientific and technical staff said that the planting area of ​​my country's economic forest is about 600 million acres. During the collection and processing process, a large amount of fruit shells, fruits, and pruning leaves are generated during the collection and processing process. Ton.

In the past, due to the lack of treatment technology, most of these remaining things were discarded at randomly on valleys, river beaches, and highways. After the rainwater was washed into the waters, the water was severely polluted; It seriously restricts the sustainable and healthy development of the economic forestry industry.

In the eyes of science and technology workers, these remaining substances are rich in cellulose, semi -cellulose, lignin and mineral elements, which are similar to the ingredients formed by the ingredients formed by edible fungus and peat. They are good raw materials for edible fungus and plant cultivation.

As a "national team" of forestry research, how to resource and harmlessly treated economic forests, realize the recycling of resources, promote the healthy development of the industry, and maintain the safety of national food and oil. problem. Beginning in 2012, the team opened the scientific and technological research of the restoration of economic forests.

Ten years of research becomes a treasure

With the support of the “Key Technology Research and Demonstration of the Maimpan of the Main Economic Forest Waste Disposal Disposal of the Major Economic Forest Waste” and the support of the national key R & D project “Filtering the Ecological Eco -Ecological Ecological Ecological Ecological Ecological Ecological Ecological Ecological Ecological Ecological Ecological Economy Variety” support, the research team has proved the fruit shell waste The main chemical composition and content. On this basis, it focuses on the remaining objects such as cashmeal and fruit shells, pecans shells, chestnut fruit shells, etc., dehydrated treatment of cultivation of edible fungi and high -temperature aerobic fermentation, matrix cultivation of flowers and seedlings, etc., and carried out system research and demonstration.

The research team consists of more than 10 scientific research and production staff. They have been studying for nearly 10 years, and repeatedly compared the effects of additives to 3 kinds of fruit shell high temperature aerobic fermentation, organic substances and harmful substances degradation, and fermentation products. Bacterial technology, 3 kinds of fruit shells, high temperature aerobic fermentation production matrix technology technology; develop a hybrid dehydental agent and high temperature aerobic fermentation technology with independent intellectual property rights, and overcome 3 kinds of fruit shell dehydration treatment matrix cultivation and consumption The key technical bottleneck of the bacteria solves the problem of poor adaptability of the remaining substances of the fruit shell in edible fungus cultivation. It breaks through the key technologies of the three kinds of fruit shells and high temperatures of different auxiliary materials and the cultivation of flowers and seedlings. The reclaimed substrate for waste and more than 30 plant cultivation has realized the local biological transformation of the economic forest and fruit shell, 100%replacement of peat, and efficient cultivation of flower seedlings.

The application of this technological achievement can handle fruit shell waste in place, near, short -term, and low cost, low pollution, low energy consumption and security and stability, providing technical support for the improvement of quality and efficiency and sustainable development of the economic forest industry.

From 2017-2021, relying on this technological achievement, 8 authorized invention patents, 2 registered software copyrights, and published 18 papers. In March 2021, the relevant results were published online in the top journal "Biological Resources Technology" in the field of biotechnology. The results won the third prize of Zhejiang Province Science and Technology Progress and the third prize of Liang Xi's science and technology progress.

The economic forest operation and processing of my country's economic forest generate about 70 million tons of waste each year. Economic forest remaining substrate materialization of seedling and substrate cultivation of food and drug bacteria can make full use of waste resources to reduce the cost of seedling matrix and edible bacteria of more than 25%, and reduce carbon emissions by about 28 million tons.

Open the results to transform the last mile

"Using practical technology to solve the realistic problems in the production of enterprises is our ultimate purpose of doing scientific research," said associate researcher Zhang Jinping.

The team led by Zhang Jinping exceeded the key technologies of cinerous production core production core production core production core production core production, as well as key technologies in the application of production matrix in flowers, seedlings, edible fungi, and vegetable cultivation. This technology is of great significance to realize the development of the economic forest industry chain.

In order to solve the needs of corporate dilemma and achievements of results demonstration, Zhang Jinping has repeatedly penetrated the scene of the first -tier enterprises and the forest farm, and guided enterprises to use waste shells, forest pruning and other wastes to perform high temperature aerobic fermentation. Fermented products completely replaced grass charcoal, cultivated tea seedlings, and cultivated oil seedlings. The thin -shell mountain walnut seedlings, Dendrobium officidal, and various flowers and vegetables are used to cultivate mushrooms, big balls, and Xiuzhen mushrooms with fruit shell waste. Among them, 100%of the fermentation products replaced the categorian categorian categorian categorian in peat 99%-100%, an increase of 5%-10%over the conventional matrix, and the land diameter and height of the camellia seedlings were increased by 36.6%and 46.7%respectively. The growth cycle was shortened by 3-6 months.

At present, this technology has been widely welcomed by enterprises and has been promoted and applied in more than 10 enterprises and forest farms in Anhui, Zhejiang, Jiangxi and other provinces. Three of the fruit shell waste dehydration treatment and cultivation of the edible fungus production line, establish 4 fruit shell waste high -temperature aerobic fermentation and matrix reclaimed production line, cumulative treatment of more than 10,000 tons of fruit shell waste, substrate replacement of miscellaneous wood cultivation consumption There are 10.95 million bats, 50,000 bottles, and more than 50 acres; the production of flower seedlings is 20000m3, and 100%of the matrix can replace more than 30 species of peat cultivation of flowers, seedlings, and vegetables. In the future, this technology will be used for economic forest land composite operation, realize the use of economic forest matrix and other economic forests in the future, and improve operating efficiency.

Zhang Jinping said: "In the next step, we will carry out the path of biological transformation to carry out planting mushrooms or on -site mushrooms under the economic forest, and nearly high temperature aerobic fermentation, realize bacteria or fermented products to return the forest on the spot, solve the use of economic forests, improve the soil, improve the soil Technical issues such as organic matter and fixation and remittances. Continue to develop the specialized seedlings and special organic fertilizers based on economic forests based on economic forests, push high -quality and precise products to the market.
