针对胶东半岛苹果园长期大量使用化学农药,导致大量杀伤天敌,果园生态结构恶化,害虫抗药性日趋严重,次要害虫暴发,果实残毒量增加等问题,作者总结了6年来研究、生产无公害苹果的经验。提出了少用化学农药,不用剧毒、全杀、对害虫易产生高抗性的1605、乐果、菊酯类农药,以应用昆虫生长调控药剂、生物药剂、高脂膜和果实套塑膜袋等技术措施为主,最大限度保护生态平衡,达到生产绿色食品苹果的目的。
For a long time, large quantities of chemical pesticides were used in apple orchards in the Jiaodong Peninsula, leading to a large number of natural enemies, deteriorating ecological structure of orchards, increasing resistance of pests, secondary outbreaks of pests and increasing residues of fruit residues. The author summarized six years of research and production of pollution-free apples experience of. Proposed the use of chemical pesticides, not to be highly toxic, kill all, the pest susceptible to high resistance to 1605, dimethoate, pyrethroid pesticides to application of insect growth regulating agents, biological agents, high-fat film and fruit sets of plastic film Bags and other technical measures to maximize ecological balance to achieve the purpose of producing green food apples.
