A Recycling Agriculture Model Based on Edible Fungi Cultivation

[Objective]This study was to explore the model for the efficient utilization of agricultural resources,especially crop straw and livestock waste.[Methods]With Shandong Jiufa Edible Fungus Co.,Ltd.as a case,this paper described a recycling agriculture model based on edible fungi,and analyzed its economic,ecological and social benefit [Results]The recycling agriculture model,guided by the scale production,processing and vendition of medium for the culture edible fungi,mainly makes use of a large amount of agriculture wastes like wheat straw,livestock waste,for developing edible fungi industry,aiming at getting the intensive optimization of fund,technology,raw materials and products at village level and more surplus labors engaged in edible fungi production industry into reality.Moreover,this model provides multi-solutions to the utilization of a great deal of fungus dreg,which can not only solve the problem of fungus dreg generated in the edible fungi production,but also extend industrial chain and enhance the income of practitioners,further realizing maximum conversion of agricultural resources.[Conclusion]This model can make well use of agricultural resources and reduce the agricultural waste pollution,significantly increasing economic,ecological and social benefits.

On Breaking Through "the Green Trade Barrier" via the Recycling Agriculture Mode

With their advantages in the field of environmental protection, by means of combining trade in the WTO andenvironmental protection, many countries and territories have laid down the principle of "the green trade barrier", whichconstitutes a serious challenge against our produce export. It is hypothesized that the basic solution to the barrier is thereplacement of the conventional agricultural mode with the recycling agriculture mode, whereby implementations and mea-sures of the new mode are put forward,

Study on the Recycling Agricultural System Operation Mechanism Focusing on Pig Farming

According to the characteristics of circular agricultural mode focusing on pig farming and by dint of system dynamics mode-based analysis techniques to analyze the characteristics,the operation force for the recycling agricultural system focusing on pig farming was put forward.

A New Model of Recycling Agricultural Production

[Objective] The aim was to research production model of recycling agricul- ture. [Method] The production model of recycling agriculture integrating planting and breeding was explored on basis of pig raising, and maize and peanut planting, with consideration of existing problems of planting and breeding integration in China. [Result] Ecological and economic benefits of pig farms and planting bases increased significantly, and all indices improved in different degrees. [Conclusion] The research provides valuable references for pig raising in China.

Supply modes for renewable-based distributed energy systems and their applications:case studies in China

Distributed energy systems(DES),as an integrated energy system with coupled distributed energy resources,have great potential in reducing carbon dioxide emissions and improving energy efficiencies.Considering the background of urbanization and the energy revolution in China,the study investigates the renewable-based DESs supply modes and their application in China.A new method is proposed to classify DESs supply modes into three categories considering the renewable resource in domination,and their application domains are discussed.A comprehensive model is given for economic and environmental evaluation.Typical case studies show that the renewable-based DES systems can supply the energy in a cost-effective and environment-friendly way.Among them,the biomass waste dominated supply mode can not only achieve"zero"carbon emissions but also"zero"energy consumption,even though not yet economically attractive under the present policy and market conditions.Thus,recommendations are given to promote the further deployment of renewable-based DESs,regarding their supply modes,policy requirements,and issues to be addressed.

Functional biochar for efficient residue treatment of sulfonylurea herbicides by weak molecular interaction

Pesticide residues have seriously damaged the natural environment and social security.Here,we prepared the efficient functional biochar(FB)for sulfonylurea herbicides from cotton straw cellulose(CSC)by hydrothermal carbonization with the methacrylic acid.The molecular simulation of FB indicated thatπ-πelectron-donor-acceptor(EDA)interaction and formation of charge-assisted H-bond were both the main factors for effective adsorption process.The adsorption process can match the pseudo-second-order kinetic equation and Freundlich model.The whole process is physical adsorption,spontaneous and rapid,and can quickly reach equilibrium.The FB with carbon-oxygen functional groups and aromatic conjugated structures can remove pesticides in water very quickly(within 30 s),with effective adsorption over 95%of Sulfonylurea herbicides(SUHs).Therefore,functional FB might be an effective way to get excellent absorbent for pesticide treatment.
