就国内外控释肥料在旱地农田中的应用效果、田间养分释放,以及高效施用做了综述,重点总结了控释肥料在不同作物上的增产效果和当前应用研究中存在的问题。施用控释肥料可以提高肥料利用率,减少氮素淋溶损失,并具有增加作物产量和改善蔬菜品质的优点,但控释肥料应用中也存在着养分在土壤中的转化和去向不明,养分释放与作物生长对应性差,忽视环境条件对养分释放影响等问题。并对今后高效施用控释肥的技术研究进行了展望。
The effects of controlled release fertilizer at home and abroad on dryland farmland application, field nutrient release and high efficiency application were reviewed. The effects of controlled release fertilizer on yield increase and the problems in current application were summarized. The application of controlled release fertilizers can improve fertilizer utilization, reduce nitrogen leaching losses, and increase crop yield and improve the quality of vegetables, but the application of controlled release fertilizers also exist in the soil nutrients in the transformation and the unknown direction, the release of nutrients Poor correspondence with crop growth, ignoring the impact of environmental conditions on nutrient release and other issues. And the future efficient use of controlled release fertilizer technology research prospects.
