山东产区套袋苹果病虫害综合防控“164”农药减施模式的设计与应用

Development and application of“164”chemical pesticides reduction mode for the integrated pest management in bagged apple in Shandong producing area

针对山东产区套袋苹果的常见病虫害,设计了病虫害综合防控"164"农药减施模式,即1个重点生态防控期、6个化学防治关键期和4个病虫重点监控期。按"164"减药模式制定适用不同地区和采用不同农药公司药剂种类的具体防控方案,在栖霞、蓬莱等地的果园连续试验2年。结果表明:试验园全年用药9~14药次,与当地常规管理的对照园相比,化学农药使用量减少50%以上;试验园的病虫叶率和病虫果率都控制在5%以内,果园内无落叶现象;病虫防治效果、果实的产量和品质、优质商品果率等项指标,与当地常规管理的对照园无明显差异。

Aiming at the common diseases and pests,of bagging apple orchards in Shandong producing area,the "164"chemical pesticides reduction mode for integrated pest management was designed.Namely,1 key ecological control period,6 critical chemical control periods and 4 key disease and pest monitor can control periods.Based on this mode,specific disease and pest management schemes suitable for different regions and using different company pesticides were designed and tested in orchards in Qixia,Penglai and other areas.The experiment results showed that the quantities of chemical pesticides applied in the experimental orchards reduced by more than 50%compared with the controlled orchards,the affected leaves and fruits by diseases and pests in the experimental orchards could be controlled under 5%,there were no deciduous in the experiment orchards,and the yield and quality of fruits and the fruit rate of high quality did not show significantly different from those controlled orchards with the conventional control orchards.
