Study On The Management Model For Large Scale Of Crop Production And Equipment Of Agricultural Machinery In Liaoning Province

Farming mechanization is an important symbol and aspect of agricultural modernization, is also a momentous measure to improve agricultural productivity and achieve strategic objectives in agriculture. As a major grain production province, the level of farm mechanization in Liaoning is at the forefront of other countries in China, but compared with developed countries agricultural mechanization is still in the intermediate stage. To display the farm mechanization potency fully, solve the contradiction between separate management of peasants and large scale management of farm machinery, it is necessary to make land lace through reasonable transfer of land and make sure that the rights of land contract belong to owners. And using large-scale management of farm machinery, peasants should create effective conditions for the agriculture modernization.This paper has collected a lot of basic data and information about mechanical management scales, management models, management systems, service systems, farm machinery level and management benefits in the main areas of Liaoning Province. On the basic of development and status about scale management of farm machinery in Liaoning Province, this paper has conducted the deep research about management model of farm machinery in Liaoning Province from two aspects of the qualitative analysis and the quantitative analysis.(1) Determination the critical scale of the mechanical management. This paper has determined the conditions for the economic critical scale about planting, proposed the condition of scale management, set up theoretical mathematical model of critical scale, and analyzed the feasible region of planting management scale and scales under different level of mechanization. Using theoretical and practical research on the combination of scale management, it gives a moderate scale range for typical areas in Liaoning Province.(2) Determination the best form about scale management of farm machinery. Benefitting from the experience of developed countries, combining with economic develoment and management scale of farmland in Liaoning Province, this paper anlyses management scale, farm mechanization level, labor transfer rate and scale benefit for the modles about rich owner of farm machinery, family farm and farm machinery specialized cooperative society, and deduces that family farm is the most moderate pattern.(3) Evaluation and analysis on the optimal size of family farms. This paper has set up index system of scale management on the family farm, selected out main factors impacting management scale using DEMATEL method, proved important degree about these factors applying gray correlation analysis method and found out in-put and out-put indexes for DEA models. It analyses technical efficiency from CCR , technical efficiency and scale efficiency from BCC, and selected the farm with 133.33hm~2 as the most moderate scale.(4) Selection and equipment of machinery. On the perspective of agricultural machinery selection, equipment, and specialized family farms, combined with different machine units, this paper puts forward a machinery equipment program to achieve the best allocation of resources incluing workers, farmland , machinery, etc..Take the moderate family farm for example, using the linear programming improvement model under assembly-line cultivation, by means of lingo software programs, this paper proposes the most optimum configuration about tractors and matching implements.
