| With the further development of industrialization, urbanization and population increase and improving people’s living standard, China’s grain supply and demand in balance for the long term, the basis of food security more vulnerable:on the one hand, China’s grain consumption demand is rigid growth:On the other hand, the cultivated land quality decline year by year in our country, water resources shortage and climate change on food production constraints increasingly prominent:Coupled with the food industry in China is facing a monopoly of foreign investment, foreign seed industry enterprises to domestic seed industry constantly impact. This leads to food security is facing severe challenges. To this end, the national program for long-term food security is put forward, with deng xiaoping theory and "three represents" the important thoughts as the instruction, the full implementation of the scientific outlook on development, according to the comprehensive construction well-off society and building a socialist harmonious society and building a new socialist countryside of major strategic deployment and general requirements, adhere to based on the basic depend to ensure domestic food supply, increased investment in policy and support, relying on the progress of science and technology, improve the scientific and technological innovation ability of grain production, strengthen the support of science and technology, promote thoroughbred breeding, optimize the structure of grain varieties grown and increase the per unit area yield of grain. Chairman in 2013, with xi jinping as the leading core of a new session of the central government is more emphasis on protecting national food security, further put forward the "food security depends on their", to "speed up the development of modern agriculture, and maintain stability of the main agricultural production development", do "food in the hand, do not panic in the heart", to "ensure national food security" and other important instructions.In the current our country accelerate the industrialization, urbanization and agricultural modernization process, relying on enlarge planting area yield potential is limited, one of the most effective way is to speed up the improved variety breeding and application, by relying on the progress of agricultural science and technology to raise the level of the existing cultivated land area per unit area yield of grain, and stable development of local food production, to ensure food security. In today’s market competition intensifying, seed industry development is more dependent on the progress of science and technology promotion, technology innovation and application, seed companies only understand new diffusion characteristics, influence factors, in order to better carry out promotion activities and developed with independent intellectual property rights and broad prospects for commercial varieties, to breed drive product advantages, and then forms the enterprise advantage, realize own bigger and stronger development goals.In this paper, the research content including:The first part, introduction. Mainly introduced in this paper, the research background, significance, research breakthrough point and the research train of thought and so on. The second part, the theoretical basis, comb the technology diffusion theory, consumer behavior theory, established a clear theoretical framework, to analyzing "99" ChengYu system of agricultural technology diffusion. The third part, the maize varieties’technology diffusion. This chapter mainly introduced the corn seed industry in our country, the proliferation of maize breeding and maize varieties, as well as the background in the whole order state NongKeSuo "ChengYu 99" research and development and diffusion of maize varieties. Preliminary prediction of agricultural technology diffusion path, lay a foundation for writing; The fourth part, the local maize varieties technology diffusion law of space-time analysis. The first section "S" curve model and regression method is used to to DaZhouShi NongKeSuo for iffusion source, "ChengYu 99" for analysis of characteristics of corn for the diffusion of technology diffusion time, build the corn technology diffusion in the area, outside the area, the whole model. And the diffusion velocity, diffusion time and diffusion path analysis. Using the correlation analysis, in the second quarter on the space characteristics of maize varieties in regional diffusion is analyzed. The fifth part, mainly from the regional economic environment, regional natural conditions and technical environment, regional agricultural technology popularization system, regional social environment five aspects analysis factors affecting "ChengYu 99" the spread of the seed corn; in the first part, on the basis of research on influence "ChengYu 99" for corn spread in the area of micro factors in quantitative analysis, understand the key factors affecting the diffusion and the mechanism of action, seek countermeasures to improve the effect of diffusion.The main conclusions of this study was to:(1) local varieties diffusion has certain regularity. Embodied in the new diffusion will experience the individual spread to regional diffusion process, the individual diffusion will experience, persuasion, decision making, practice, define the five phases, accord with "S" curve of diffusion path; New accord with asymptotic diffusion on the space, also conforms to the diffusion. (2) varieties technology diffusion by the advantage of the technology itself, the regional economic environment, natural conditions, technology environment, the promotion system, macroeconomic factors such as social culture, level of education, access to information channels, farmers expected economic benefits, the price of new integrated micro factors.(3) the combination of government and market driving is an important force of technology innovation diffusion.(4) breed choose the intention and the factors affecting the choice behavior of diffusion have differences, factors that affect choice will boil down to the farmers own, the intrinsic properties; Factors that can affect the choice behavior can be attributed to external, existing properties.In conclusion, put forward the following countermeasures:(1) change the idea, to follow the law of diffusion effectively promote science; (2) creating the condition actively guide farmers to select new varieties and promote proliferation, (3) improve, innovation, technology diffusion way, perfect marketing mechanism; (4) we will continue to improve the related intellectual property rights (ipr) protection, technical and social environment to promote health. |
