提高肥料利用率的因素与对策

Factors Analysis and Countermeasures of Increasing Fertilizer Use Efficiency

化肥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,加重农民经济负担,同时造成对环境的负面效应。从旱田和水田2个角度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。

Much more fertilizer being used,deteriorate physical and chemical properties of soil,low crop yield and quality and the resources being wasted are caused by the low fertilizer use efficiency,which is aggravating farmers＇ burden and taking the negative effects to environment.The ways and methods of increasing the fertilizer use efficiency were summarized,striving to provide the theoretical references to reverse ＂Crop yield doesn＇ t increase but the fertilizer quantity increases＂,＂Excessive accumulation of the soil nutrient＂ and ＂Serious loss of nutrient and low efficiency of production＂ from upland and paddy field.
