摘要
通过将先进的地理信息技术和传统的土壤、叶片营养诊断技术结合,在充分考虑橡胶园供肥特性、胶园产量水平、目标产量和橡胶树叶片营养、化肥利用率和肥料特性等众多因素的基础上,以海南省龙江农场为例,基于GIS软件MapInfo,建立精准变量施肥的田间土壤养分和叶片养分信息数据库,进行橡胶树营养诊断分析,提供施肥决策支持,并指导变量施肥作业。
According to the combination of advanced Geographic informtion technology and traditional nutrition diagnose technology of soil and vane, based on the study of robber plant fertilizer feed character,output level of robber plant,target output,vane nutrition of rubber plant,fertilizer utilize ratio, taking Longjiang farm of Hainan as example, with GIS software Mapinfo, nutrition database of soil and vane for exact fertilization was built .The system can analyze and diagnose rubber plant nutrition, supply fertilization decision support and guide variable fertilization task.
