摘要
针对设施农业中硝态氮淋溶严重的问题,研究了硝态氮淋溶的主要成因,其中施肥量、灌溉方式、栽培模式等是影响硝态氮淋溶的主要因素.总结了有效减少硝态氮淋溶的措施,主要包括优化施肥、合理灌溉、合理栽培等,这些措施既可节约资源,又能够降低氮淋溶对生态环境的影响.
Abstract
Aiming at the serious problem of nitrate nitrogen leaching in facility agriculture,the main causes of nitrate nitrogen leaching were studied,among which the amount of fertilizer,irrigation method and cultivation mode were the main factors affecting nitrate nitrogen leaching.In addition,the effective measures to reduce nitrate leaching are summarized,including optimizing fertilization,rational irrigation,rational cultivation,etc.These measures can save resources and reduce the impact of nitrogen leaching on ecological environment.
