我国北缘桔区柑桔主要病虫害综合治理技术体系的研究

Studies on Technical System of Integrated Control for Major CitrusDiseases and Insect Pests in North marginof Citrus Region in China

在对柑桔主要病虫害综合防治技术系统研究的基础上,以我国北缘桔区特定的生态条件为背景,结合现有的生产水平,组建了我国北缘桔区柑桔主要病虫害综合治理技术体系.该体系由关键性技术、信息、决策、推广和评价反馈5大系统组成;并概述了该体系建立的原理和指导思想.在汉中市、南郑县、勉县的5年试验示范表明,该技术体系的运转实施,经济、社会和生态效益显著提高.

The background of this studies is a special ecosystem in the north margin of the citrus region in China, taking into consideration of the level of productive forces, the technical system of integrated control for major citrus diseases and insect pests are built up. This system is composed of 5 parts : the Key Technical Subsystem, Information, Decision-making, Extention and Appraise Feedback Subsystem. The results of field experiment and actual contrlol during 5 years at Hanzhong, Nanzheng and Mian county showed that significant economic benefits, social benefits and ecological benefits are gained after setting this new system.
