矮化密植苹果园病虫害综合防治技术研究

通过对河南省矮化密植苹果园优势病虫种类、主要天敌种类、主要病虫发生危害规律、覆草园天敌种群变化的系统调查研究，通过设置频振诱虫灯诱虫试验，高效、低毒、低残留化学农药及生物源农药筛选试验，制订出了适用于矮化密植苹果园的病虫害综合防治配套技术。实施该项技术后，病虫危害降低3倍以上，果品经检测无农药残留，经济、生态、社会效益显著。

Technological Research on Comprehensive Prevention and Control of Plant Diseases and Insect Pests in Shortenized and Densely planted Apple Orchards

Systematic investigations and studies have been carried out in the shortenized and densely planted orchards of Henan Province. They cover the studies of main plant diseases and insect pests sorts, main natural enemy sorts, general plant diseases and insect pests harm law and grass-covered orchard natural enemy species changes. We have also done the experiments of installing the oscillating frequency moth-killing lamps, and the experiments of choosing the highly effective, least poisonous, least remaining chemical and biological pesticide. Through the investigations and experiments, we have worked out a set of techniques of the comprehensive prevention and control of plant diseases and elimination of pests, which are suitable for the shortenized and densely, planted apple orchard. After the techniques have been carried out, the harm of plant diseases and insect pests has been reduced by three times. The fruits have been tested to be non-pesticide remaining. And it is economical, ecological and has obvious social profits.
