Analysis On The Energy Flow, Materials Flow And Value Flow Of Two Cycle Of Production Mode In Oasis Irrigation Region

Northwest inland irrigation areas rich in light and heat resources and serious shortage of water resources, but traditional agricultural still dominated the production charactered by high input and high output of energy consumption, that has affected the efficiency and continuous of agriculture's development seriously. In the background of scientific diagnosis in agricultural resources, and basis of fully draw on the success of agricultural development at home and abroad, constructer of a new agricultural development pattern which applied to oasis, realize for low consumption of resources and high efficiency of the production and low-emission pollution in agriculture has become a pressing problem in the area's sustainable development. Cycle agriculture is agricultural production patterns which based on the concept of circular economy and sustainable development, the pattern of agricultural systems achieved ecological optimization and sustainable development of agriculture through the optimization and adjustment of the internal structure and industrial structure and extend the industrial chain, implement multi-recycle use of material and energy in agricultural and reduce environmental pollution and ecological damage maximum, it is considered an important direction for future agricultural development. So, in this study combined the method of farmers survey and test, analyzing and comparing the energy input structure and status of NPK input and output and value conversion of"Straw-Agaricus bisporus"(modeâ… ) and Wheat(modeâ… ), discusses its energy flow, logistics and value of the number of flow characteristics. Investigate the relationship between resource cycle use efficiency and integration of new technology, bio-canada, in order to provide a reference for building the resources effective recycle using modes in the oasis irrigation. Conclusions are as follows:1. The results of energy flow show: the structure in input energy is basically the same cast of two patterns, were dominated by organic energy input. In the organic energy investment, manure dominated the main part, labor and animal power investment is low. thus, fertilizer and fuel and other were the main investment in inorganic energy input."Straw-Agaricus bisporus"recycling productive system was higher in the level of energy input compared to Wheat, it was benefited to crops yield, the proportion of organic energy input was increased, it showed that"Straw-Agaricus bisporus"had a stronger ability to self-production, it is affective less by human's intervention. The proportion of labor and animal's power is low, it show that Wuwei has basically realized mechanization. From the structure of fertilizer, the input of organic fertilizer is more than others of two patterns, but the proportion in organic fertilizer input of farm-bacteria system is more higher than the traditional system. This is important to maintain and restore soil fertility and increase production capacity of system and increase the system's output and stability.2. The results of materials flow show: The inorganic inputs were the absolute superiority about N,P and K of the two pattern's production, it showed that farmers put more emphasis on chemical fertilizers in the area, the Wheat production system were higher in output/input of N,P and K compared to"Agaricus bisporus". The"Agaricus bisporus"production system was higher than wheat production system in nutrient surplus, compound to improve the nutritional content of soil and cultivate a positive role, more conductive to fertility. The wheat production system lacked K, crops have been plundered soil's K, such a negative cycle in long-term, it will lead to concentration of K in the soil less and less.3. The results of value flow show: The value of two productive patterns into the same structure, were the absolute superiority of industrial investment, the two systems were the largest fertilizer investment in industrial value. The output/input of industrial funds investment was higher, and efficient use of funds was higher, biological funds investment was low compared to industrial funds investment. That explained that industrial capital investment can yield greater value."Agaricus bisporus"production had higher net income, it greatly improved efficiency and have greater potential development.4. Wheat production system had great quality of ancillary products(straw), but not fully utilized, and caused environmental pollution,"Agaricus bisporus"production system are the relatively low ratio of output to input, but the pattern can take full advantage of waste wheat straw and cow dung in wheat production and eliminate the pollution of straw burning and the dumping of the odor pollution of cow dung, to protect resources and the production environment. Waste of bacteria can also be used an organic fertilizer residue into farmland, improve the soil to increase crop yields, to achieve the virtuous circle of waste-using to added value and synergy, it fully reflects the cycle of economic and sustainable development of ecological agriculture. The pattern is simple and universal access to basic public was good and has great potential development.
