福建省漳州市平和县为琯溪蜜柚主产区,其过半果园处于土壤磷环境高风险状态,果园面源污染严重。从产量、效益及草被固定氮、磷、钾量等多方面差异,说明了在土壤磷环境高风险果园采用施肥减量化技术,可很好地控制果园面源。 Pinghe County, Zhangzhou City, Fujian Province, is the main producing area of ​​Guanxi honey pomelo. Most of its orchards are in a high-risk status of soil phosphorus environment, and the non-point source pollution of orchards is serious. From the aspects of yield, benefit, fixed nitrogen, phosphorus, and potassium content of grass, this paper shows that applying fertilizing and reducing technology in orchard with high risk of phosphorus in soil can control orchard surface source well.
