摘要
土壤中农药污染的问题已在国内外引起越来越多的关注,但消除或降低农药污染带来的风险仍缺乏简单、实用和高效的途径。已有较多研究表明,施肥能够影响土壤中农药的降解转化,系统研究施肥与农药降解的关系,可为预测土壤中农药降解转化,建立科学的施肥模式,加快农药降解提供依据。基于土壤理化性质和生物学性质,分析了施肥影响土壤中农药降解的机制,结合已有的研究,提出了开展施肥影响农药降解的研究应重点关注农药种类、土壤类型及复合污染等问题。
More and more concerns on the pesticide pollution had been made worldwidely. However, till today, there are few simple, practical and high efficient methods to remove or decrease risks of pesticide pollution in soil. Many studies showed that fertilization had indirect and direct effects on the transformation of pesticides in soil. Systematical studies on the influence of fertilization on the degradation of pesticide could help us to predict the transformation of pesticide in soil, establish scientific fertilization mode and promote the pesticide degradation. Based on the soil physiochemical and biological properties, the influencing mechanisms were discussed. Consideration of the reported studies, pesticide kind, soil type and combined pollution should be paid more attentions in the future studies.
