摘　　要：对油菜田、小麦田以及相邻空地的空气负离子监测,研究了冬季油菜和小麦对空气负离子的贡献。结果表明:油菜和小麦能增加周边环境中空气负离子浓度,且在幼苗期表现明显;油菜和小麦虽属不同的科,但对环境中空气负离子产生的贡献无明显差异。The contribution of winter-season crop-rape and wheat to the negative air ions were monitored in the experimental fields. Though the negative air ion concentration was sensitive to atnbient environment, we found that rape and wheat crops can contribute to increase negative air ions in ambient air. This kind of contribution was nmch more obvious especially in the period of young crop and no sig,lificaot difference of the contribution between rape and wheat was found though they represented dicotyledon and monocotyledon respectively.
