摘要
化学肥料利用率低不仅造成过量施肥,土壤理化性质恶化,影响农作物产量和质量,还会浪费资源,同时造成对环境的负面效应。本文根据测土配方施肥项目中肥料高产高效优化管理技术的要求综述了提高肥料利用率的方式方法,力求为扭转"增肥不增产"、"土壤养分过量累积"、"养分损失严重和生产效率下降"的现行局面提供理论依据。
The low utilization of chemical fertilizer,not only caused by excessive fertilizer,degradation of soil physical and chemical properties,affect crop yield and quality,will waste of resources,at the same time cause the negative effect on the environment. According to the measured soil fertilizer project in high yield and efficient optimization management technology are reviewed in this paper to improve the utilization ratio of fertilizer,and try to reverse the add fertilizer production,excess nutrient accumulation and nutrient loss serious and productivity decline provide theoretical basis for the current situation.
