摘    要:香蕉枯萎病是一种传染性极强的土传病害,对生产危害极大。从研究香蕉种植户对枯萎病的认知特征和防控技术行为入手,可以为科学防控枯萎病提供基础。本研究以海南、广东、广西、福建和云南等香蕉主产区的20个县(区)的133份调查资料为样本,采用结构方程模型进行研究,结果表明:认知程度直接影响香蕉枯萎病防控技术的扩散,防控成本、受教育程度、收入水平、技术培训经历和种植经验等均不同程度地影响种植户对枯萎病的防控行为;蕉园土壤酸碱度及有机质含量、抗逆品种的选择对枯萎病蔓延有一定的影响。引导和规范种植户修复土壤、重施有机肥、注重土壤酸碱度平衡等生产技术行为,可以抑制或减缓枯萎病的蔓延;拓展香蕉种植户对枯萎病防控技术的认知深度,以“技术的供给与需求相结合”为导向,加大扶持力度,建立起枯萎病统防统治等综合防控体系,可以达到抑制枯萎病的目的。

关 键 词:香蕉枯萎病    技术    认知    影响因素    结构方程

Abstract:Banana fusarium wilt has great harmful to the agricultural production, which is a highly contagious soil-borne diseases. Therefore, the study on farmers' cognitive characteristics and control behavior of banana fusarium wilt, will provide foundation for scientific prevention and control of wilt disease. This paper takes 133 scattered rural households survey data as the sample which is collected from 20 counties(districts) in the major banana production area of Hainan, Guangdong, Guangxi, Fujian and Yunnan, and introduces structural equation model to analyze these collected questionnaires. One of results of this study shows that cognition degree of banana fusarium wilt among growers has a direct impact on the diffusion of this disease's prevention and control technology. Specially, these factors such as educational level, income standard, technical training and the experience in planting etc. all have effects on the growers' behavior of control of banana fusarium wilt. Another result of this article indicates that banana plantation's soil PH, organic matter content and the selection of stress-resistant varieties also have some influence on the spread of fusarium wilt. In addition, some measures are proposed accordingly, such as restoring the soil, emphasizing the application of organic fertilizer, focusing on the balance of soil PH etc., these production techniques can guid and normalize growers' behavior. What's more, expanding growers' cognitive depth on the control technology, combining technological supply with its demand, strengthening government's support efforts, establishing a perfect system of integrated prevention and control, which can also achieve the purpose of inhibiting banana fusarium wilt effectively.
Keywords:banana fusarium wilt  technology  cognition  influence factors  structural equation
