摘　　要：化肥在提高作物产量的同时也带来很多问题,由于作物对肥料的吸收是一个缓慢过程,大量的肥料不能及时被作物吸收而造成了环境污染,因此,有效提高传统化学肥料的利用率,能够减少对环境的污染。包膜控释肥在一定条件下能够实现对肥料养分释放速率的调控,显著提高肥料利用率,减少因肥料流失造成严重的环境污染。包膜控释肥的膜材是决定肥料控释性能的关键因素之一,本文对比分析了不同性质的膜材的优缺点及其对肥料控释性能的影响,解释了包膜控释肥养分释放机制,阐述了包膜肥在现实应用中存在的问题及对未来发展的展望。Fertilizer not only improves crop yield,but also brings many problems.As the absorption of fertilizer by crops is a slow process,a large amount of fertilizer cannot be absorbed by crops in time,which causes environmental pollution.Therefore,effectively increasing the utilization rate of traditional chemical fertilizers can reduce environmental pollution.Coated controlled-release fertilizer can regulate the release rate of fertilizer nutrient under certain processes and conditions,significantly improve the utilization rate of fertilizers and reduce the serious environmental pollution caused by fertilizer loss.The membrane material of coated controlled release fertilizer is one of the key factors to determine the controlled release performance of fertilizers.In this paper the influence of the advantages and disadvantages of different membrane materials on the controlled release performance of fertilizers were compared and analyzed,and the nutrient release mechanism of coated controlled release fertilizers was explained.The problems in the practical application of coated fertilizers and the prospects of its future development were explained.
