Research On The Utilization Of Rural Biogas Fertilizer In Linying County

From the contents of the No.1 central document issued in recent years,we can see that "green" and "recycling" are becoming the direction of agricultural development in the future.At the same time,under the influence of the aging of rural population,the transfer of young labor force to non-agricultural industry,and the acceleration of rural land transfer,the new type of agricultural operation subject develops rapidly.Therefore,it can play a positive role in the development of modern agriculture to deal with the pollution discharge of the new type of agricultural management and realize the recycling of production resources.The use of biogas fertilizer can not only deal with agricultural pollution,but also reduce the use of chemical fertilizer and promote the growth of crops,which meet the development requirements of modern agriculture.Therefore,the purpose of this paper is to improve the utilization effect of biogas fertilizer,combing the relevant literature at home and abroad.Based on the theories of sustainable agriculture,circular agriculture and farmers' behavior selection,Linying county is chosen as the research site,and the new agricultural operation subject is chosen as the research object.Through relevant data collection and field investigation,the conditions,current situation and mode of local biogas fertilizer utilization are analyzed.At the same time,select the typical farm as a case to calculate the benefits of biogas fertilizer utilization.Through the analysis of agricultural production and utilization of Biogas Fertilizer in Linying County,it can be found that the utilization of biogas fertilizer by local farmers is low.However,the utilization of biogas fertilizer tends to increase with the construction of large and medium-sized biogas projects to treat agricultural wastes.At present,there are three modes of utilization of Biogas Fertilizer in Linying County,i.e."farm + farmer" comprehensive utilization,"farm + plantation" external circulation,"pig biogas grain" internal circulation.It is found that although biogas fertilizer is different in the main circulation,it belongs to the combination of planting and breeding.After calculating the economic,social and environmental benefits of biogas fertilizer utilization in Enguang ecological breeding farm,and combining the utilization of local biogas fertilizer,the following conclusions can be drawn: biogas fertilizer utilization can effectively combine planting and breeding,increase the agricultural operation income,and also play a huge role in resource recycling and environmental protection;compared with household biogas pool,biogas The project can not only make up for the shortage of biogas fertilizer raw materials,but also increase the utilization efficiency of biogas fertilizer.Although the combination of planting and breeding is the current mainstream situation of biogas fertilizer utilization,the raw materials of biogas fertilizer mainly come from the manure produced by livestock,so the development of breeding is the key to ensure the utilization of biogas fertilizer.Although the construction of biogas project is developing rapidly in Linying County,it is found that there are still some defects in the management of local biogas equipment after investigation.At the same time,the output of biogas fertilizer is not stable,the form of using biogas fertilizer by agricultural production personnel is rough,and the local discharge of biogas slurry and biogas residue is also lack of corresponding supervision.Therefore,based on the actual situation of the utilization of Biogas Fertilizer in Linying County,this paper puts forward the following suggestions: strengthen the popularization of biogas knowledge,improve the maintenance service of biogas;enrich and promote the utilization methods of biogas fertilizer through multiple channels;promote the commercialization development of biogas fertilizer through policy guidance.
