Feedback Study On The Development Of Circular Agriculture System Of Scale Planting And Cultivating In Jiangxi

The scale planting and cultivating is an important way to increase the income of farmers in the field of agricultural production, however, with the expansion of the scale of pig breeding, the harm of aquaculture waste pollution to agricultural ecosystem can not be ignored. A large number of studies show that, in the breeding area to build a kind of circular agriculture development mode is an effective model to solve this problem. The paper aimed at waste management of scale breeding industry、biogas engineering construction、comprehensive development and utilization of biogas engineering output、the development model of circular agriculture and the mode of management and so on.This paper analyzes the current situation of the development of circular agriculture in Jiangxi, and the problems in the process of development. This paper analyzes the following contents, including the development model and the dilemma of the development of circular agriculture system of the scale planting and cultivating 、constraints of different stages of the development of the system 、lever solution to eliminate the upper limit of growth. On the basis of this, this paper constructs management mode of circular agriculture of the scale planting and cultivating of integrating multi subject. In view of the dilemma of system development of circular agriculture of the scale planting and cultivating and the restriction of different stages,this paper puts forward the goal and responsibility of each subject in the governance mode.To realize the overall goal of the development of the circular agriculture system by the way of realizing goal and responsibility of the enterprises, farmers, government departments and scientific research institutes.In view of the problems in the development of circular agriculture and the lever solutions of various development stages, this paper puts forward the specific safeguard measures for the management mode of circular agriculture of the scale planting and cultivating.This paper makes a research on the technology innovation of feedback dynamic complexity analysis.This paper presents an innovative system analysis technique for minimum feedback based mode. In this paper, we use the analysis technology to carry out the management of the feedback loop development, and to generate the management countermeasures to promote the function of the system.Taking theDebang circular agriculture system of the scale planting and cultivating as an example,the paper establishes the basic tree model of the flow rate of eight trees which can effectively describe the actual problem. The paper uses the innovative method to calculate the system’s minimal feedback matrix model which is composed of eight small modules of the system. The eight Minimal base model can be effective characterization of livestock waste pollution control system development, anaerobic fermentation output secondary pollution control system development, field user cooperation low carbon circular agriculture mode to promote system development of three different stages of the leading structure of system, and facilitating the generation system development of three management countermeasures based on the minimal model analysis.In this paper, we establish the Debang circular agriculture system of the scale planting and cultivating system simulation model equation, simulation analysis the effect of three management countermeasures, to realize the integrated qualitative and quantitative analysis.
