摘要
在辽宁省有代表性的烤烟产区 ,经过7年的田间试验 ,得出了在不同肥力水平土壤条件下的烤烟适宜肥料用量范围、肥料效应模型和适宜的施肥方法。应用ViaualBasic高级程序设计语言建立了计算机推荐施肥应用系统。应用系统可根据对不同土壤区域的土壤有效养分含量与施肥量的定量分析对肥料施用数学模型进行数据优化并给出最佳施肥方案 ,用于烤烟种植推荐施肥与咨询服务 。
Through 7-year field experiments in the tobacco-planting areas in Liaoning Province, we have obtained the suitable fertilization ranges, fertilizer effectiveness models and the suitable applied methods under the different soil conditions. The computer recommended fertilization system was established with the VB and the fertilizer application models. This system could optimize the parameters and provide the best fertilization plan, which serves the recommendation fertilization and consultation for tobacco cultivation.
