摘　　要：利用浙江省多点玉米肥料田间试验的资料建立玉米计量施肥咨询系统。在建立施肥数据库的基础上，用养分平衡公式确定Ｐ和Ｋ 用量；“以产定Ｎ”公式确定Ｎ用量。用ＶｉｓｕａｌＢａｓｉｃ语言建立系统界面和系统集成。Advisory system for corn quantitative fertilization was developed with the data of mutiple site field experiments of corn grown on hilly red soils in Zhejiang. The rate of P and K was computed with nutrient balance fertilization formula, and N was computed accoring to yield level of corn. System face design and integrated was completed with Visual Basic.
