铜制剂农药对生态环境影响研究

Study on Effect of Cupric Pesticides on Eco-environment

摘要: 阐述了因长期施用波尔多液致使铜在果园土壤中的残留积累状况及其对果园作物生长的影响。对几种新的铜制剂农药在果树和蔬菜上的残留进行了试验，并对其在今后使用中铜在土壤中的积累规律及允许安全使用年限作了预测。

Abstract: The residue accumulation status of copper in orchard soil where bordeaux mixture was applied for many years, its effects on fruits and intercrop and interplant ing of another crop were elaborated. The accumulation pattern of copper in s oil, and the allowed years of the safety use of some new cupric pesticides in the fu ture application were predicted with the experimental results of their residues in fruits and vegetables, and the practical experiences of bordeaux mixture applied in orchard over a long period of time.
