温室番茄病虫管理中的人力资本效用初探——以杨凌秋延后温室番茄病虫管理为例

The Preliminary Exploration for Human Capital Utility of Tomato Pest Management in Greenhouse——Taking the greenhouse in Yangling after Autumn as a case

蕴含于人体内各种知识与技能的存量总和为人力资本,面对温室番茄生产的过程就是操作者人力资本的释放过程。然而,人力资本释放是否有效,与多种因素有关。以杨凌秋延后温室番茄生产中的有害生物管理为例,研究人力资本在生产过程中的释放科学性。结果表明,6户代表性农户的温室中病害持续发生,平均病情指数最低25.1%,最高达到56.5%;防治投入的农药与劳动力成本最低为592.3元,最高为1823.2元;将病虫防治效果、投入与农户的人力资本要素进行相关性分析以及多目标综合判别,得知阅读书籍与病虫防治的效果和成本呈显著相关关系,接受教育以及培训同样有助于提高农户的人力资本效用,降低生态污染的风险。

Human capital is the collection of knowledge, talents, social and personality attributes, embodies in the ability to perform labor in greenhouse tomato producing so as to produce economic value. However, the utility of human capital releasing relies on many factors. This paper evaluated the utility of human capital in the process of greenhouse tomato pest control in Yangling. Through analysis, diseases occurred sustainably in greenhouses of 6 typical farmers. The lowest of average disease index was 25.1%, and the highest was 56.5%. The lowest input of pesticides and labor costs was 592.3 RMB,and the highest was 1823.2 RMB. The correlation analysis method and multi-objective comprehensive discriminating method were used for analyzing the relationship between pest control effects, inputs and typical farmers＇ human capital, and made the result that reading was significantly correlative with effects and input during pest control, education and training can also improve utility of farmer＇s human capital and reduce pollution.
