摘　　要：通过对长绒棉氮肥运筹管理的最新资料的研究及实验论证,在分析氮肥对长绒棉产量、株高和叶面积影响的基础上,综合考虑气候条件、土壤理化性质、产量目标和品种特性等影响因子,根据养分平衡原理,建立长绒棉氮肥运筹的动态知识模型,并利用VC++开发平台和SQL Server数据库软件设计实现了长绒棉种植管理支持决策系统。Through analyzing the newest research result on nitrogen management of cotton and experimental results, on the base of the different effects from nitrogen on cotton yield, plant height and leaf area, a dynamic knowledge model for decision making on total nitrogen and their distribution among main growth stages of cotton under different environments and yield targets was developed, with the principles of nitrogen balance and by integrating the factors of climate, soil, yield and variety. A comprehensive and intelligent knowledge model-based decision support system for cotton management was established using VC＋＋6.0 and SQL Server 2003.
