摘要
为准确掌握保山市主要作物肥料的实际使用情况,深入推进化肥减量行动,2021年对保山市2845户农户施肥现状进行调查。结果显示,保山市不同作物农户施肥数量、施肥比例、施肥次数、施肥方式存在较大差异;重施大量元素肥料轻施或不施中微量元素肥料情况突出,大部分作物有机肥施用量不足。结合测土配方施肥项目数据库,为保山市提出了合理的施肥技术及施肥方法,旨在为提高测土配方施肥技术覆盖率、防治农业面源污染、实现农业可持续发展提供技术保障。
In order to accurately grasp the actual use of main crop fertilizer in Baoshan City and further promote the fertilizer reduction action,the fertilization status of 2845 farmers in Baoshan City was investigated in 2021.The results showed that there were great differences in the number,proportion,frequency and mode of fertilization among different crop farmers in Baoshan City.Heavy application of large amount of element fertilizer,light application or no application of medium and trace element fertilizer was prominent,and the amount of organic fertilizer was insufficient in most crops.Combining with the database of soil testing and formula fertilization project,this study proposed reasonable fertilization technology and fertilization method,aiming at providing technical support for improving the coverage rate of soil testing and formula fertilization technology,preventing and controlling agricultural non-point source pollution,and realizing sustainable agricultural development.
