    摘要:

    病虫草害防治是水稻生产最关键的环节之一,科学正确的技术信息在提高农户病虫草害防控能力和保障国家粮食安全方面发挥了重要作用。基于长江中下游流域3个省的963户水稻农户调查数据,采用Probit和Tobit模型,分析病虫草害发生和农户防治行为的现状,探讨不同技术信息来源对农户病虫草害防治行为的影响。结果表明,在病虫草害层面,农户累计面临病虫草害发生种次10 003次,其中被农户防治的病虫草害种次占比仅为34.29%;在农户层面,平均每户的病虫草害防治率仅为35.20%。中国多元化的农业社会化服务体系已经形成,除个人经验外,农技员和农药零售店是农户获取技术信息的主要来源。相比于农药零售店提供的技术信息,农技员提供的技术信息对农户病虫草害防治概率和病虫草害防治率均有显著的正向影响,但农技员的技术服务效果并未在不同类型的病虫草害防治中形成一致性结论。因此,政府部门应该建立农作物病虫草害监测制度、深化农技推广体系改革、加强对农药零售店的技术指导与培训、鼓励统防统治等病虫草害防治商业服务体系的发展。

    Abstract:

    Pest control is one of the most necessary links in rice production. Scientific and correct technological information has played an important role in improving farmers’ pest control capability and ensuring the national grain security. Based on a survey data of 963 rice farmers in 3 provinces in the middle and lower reaches of the Yangtze River basin, this study analyzed the current situation of pest occurrence and farmers’ pest control behaviors by the Probit and Tobit models and discussed the effects of different technological information sources on farmers’ pest control behaviors. Results show that there were total of 10 003 observations regarding pest occurrence for rice farmers, of which only 34.29% of them were controlled by farmers at the pest observation level. In addition, the average pest control rate per farmer is only 35.20% at the farm level. A diversified rural social service system has been gradually established in China. In addition to personal experience, agricultural extension agents and pesticide retailers are the main technological information sources for farmers. Compared with that from pesticide retailers, technological information from agricultural extension agents has significantly positive effect on the probability and the rate of pest control. However, the technological service effects of agricultural extension agents have not reached a consistent level in the control of different types of pests. Therefore, the government should establish a monitoring system for pests, deepen the reform of the agricultural extension system, strengthen technological guidance and training for pesticide retailers, and encourage the development of commercial service systems for the pest control such as specialized and unified prevention.
