摘要
本文对化肥的增产作用和对生态环境的促进作用,以及化肥施用对土壤、水体、大气环境和农产品质量安全带来的重金属、硝酸盐污染等问题进行了研究,提出应重视化肥施用可能对农业环境和农产品质量安全带来的潜在危害,但只要正确施用化肥不会给农产品质量安全带来大的危害,今后还应进一步加强化肥施用与农产品质量安全的关系的研究。
The increasing effect of fertilizers on the outputs of farm products and the promoting effect on the ecological environment was discussed.The pollution problems of heavy metal and nitrate to soil,water,atmosphere caused by fertilizer application were also discussed.It was pointed that fertilizer application could result in the potential harmfulness to the agricultural environment and the quality security of farm products.However,the harmfulness could be reduced greatly by suitable application technology.In the future,it was suggested that the relationship between the fertilizer application and the quality security of farm products should be studied further.
