Study on the Influencing Factors of Farmers' Purchase Behavior of Organic Fertilizers Based on Logistic Model

The widespread use of chemical fertilizers has played an important role in China's agricultural development, but with the increasing input of chemical fertilizers, it has caused serious impact on the ecological environment, leading to agricultural non-point source pollution, food safety and many other problems. In order to promote the sustainable development of agriculture, China has issued a series of policies to popularize organic fertilizer in agriculture, which can not only improve the quality of agricultural products, promote agricultural production and increase income, but also make resource utilization of urban and rural organic wastes and protect the environment. Farmers are the main force of agricultural production and also the main body of rural environmental protection. It is of great significance to study farmers' ecological behavior. Through a survey of 407 farmers in the surrounding areas of Chengdu, Sichuan Province in 2019, and the logitstic model constructed based on the survey data, this article analyzed the factors influencing farmers' behavior in purchasing organic fertilizer. The results show that 12 indexes such as farmers' gender, education level, and the number of family farmers are the main factors influencing farmers' purchase of organic fertilizer. At the end, the article puts forward relevant policy recommendations to guide farmers to purchase and apply organic fertilizer.
