The Study On Influence Factors Of Farmers' Adoption Of "Wheat/Corn/Soybean" Planting Model

The domestic soybean supply is not enough for soybean demand in China, imported soybean with its low price and high oil-containing has occupied seventy percent of Chinese market. The soybean production in Norththern China is restricted by many unfavorable factors, such as limited growth in soybean planting area, yield decreasing induced by continuous-cropping, high cost by separating production from marketing areas, and so on. To develop relay-planting soybean in Southern China is very important for the soybean industry and food security of China.Southern China with superior natural conditions and small cultivated area per person is a major agricultural production area in China, and the relay-planting soybean is encouraged by several obvious advantages, for example coexistence consonantly with other main crops, high protein content, benefits to soybean-food industry, the strong resistance to drought, high yield and income per unit area and so on " Wheat/Corn/Soybean " planting model which takes soybean as the key crop of its system is one of new arid land multi-ripe planting models. Since 2003, " Wheat/Corn/Soybean" planting model has been putting in practice in demonstration area in Sichuan province, and its planting area has increased year by year because of good comprehensive benefits. But it developed very slowly in other area, most extension area are still remained in the demonstrating stage. Traditional cultivating methods are being used by most of the farmers and their cultivating skills have not been improved. The core techniques of new planting model are not been put in practice actually. Finding out restrict factors in new planting model adoption through the analyzing of farmers adoption behavior in Sichuan country is very important for the promotion of new agricultural technology, and for the expansion of soybean planting area in south China.My paper is based on the behavior theory and innovation diffusion theory, some successful study and questionnaires of 439 farmers in Nanchong, Guangan, Dazhou, Siuning, Mianyang, Jianyang, Luzhou and so twelve cities of Sichuan province. At first, the paper describes the overall statistics about the questionnaires, and analyzes the relationship between farmers'adoption and influence factors both from internal and external point of view. Second, author uses Binary-logistic model to analyze farmers' adoption on "Wheat/Corn/Soybean" planting model from four aspects, such as personal characteristics, family characteristics, technical characteristics of planting model and environmental characteristics to find the main influence factors. At last, the article gives five political suggestions.According to results of theoretical and empirical research, three conclusions are drawn:(1) With good comprehensive benefits, the planting area of" Wheat/Corn/Soybean" planting model has increased rapidly in Sichuan, but the development level of demonstration areas is different form non-demonstration areas, the gap between them is huge. Because lack of projects supported and government policies supported in non-demonstration areas, farmers generally did not receive professional training, their adoption rate of relevant technologies is low. And the most of farmers solve problems when adopting new planting model on their own. So the farmers'evaluation of comprehensive benefits of new planting model is general. Combined with the lack of technology research on new variety, agronomic and agricultural machinery, the further promotion of " Wheat/Corn/Soybean" is being challenged.(2) The major influence factors of farmers'adoption are as follows:planting habit and education degree of farmer, cultivated area, pig-breeding, the technical characteristics of planting model such as yield increase, labor cutback, soil improvement, drought resistance, and government policy about new planting model, agricultural extension system. And these influence factors include the age, gender and social identity of farmer, and the main source of income, amount of labor, and the characteristics to prevent pests and diseases of planting model, and the marker risk, changes of diet which do not have any impact on farmers'adoption.(3) Through the analysis of development situation and farmers'adoption of Wheat/Corn/Soybean" planting model, five political advices are suggested to promote the application and extension the of new planting model.①The government should strengthen the policy guidance and establish appropriate agricultural extension system.②As to establish the synthetic technique system of new planting model, research institutions should strengthen the research on matching technology such as new variety, agronomic and agricultural machinery.③In order to promote the industrial production of soybean, leading enterprises should be greatly developed.④The scientific and cultural qualities of farmers should be improved and their traditional farming practices should be changed.⑤As to expand planting scale of farmer, it is necessary to establish the transfer mechanism of rural abandoned land.
