摘要
本文用北京某农场各队历年的施肥量与产量的财务记载资料,建立施肥量与产量的关系模型,确定化肥施用量对产量的影响,并编制拟合模型参数和数据分析的BASIC程序。通过分析研究,确定出果园施肥的最佳用量。
The model were estabolished on the relationships the ferlizer input to the apple
production based on the date of a farm in 1985-1989 in Beijing area,by which model the
optimum fertilizer input were defined in this report.And also this research provided a BA-
SIC programme to be able to use to analysis the effect of the fertilizer input on the fruit
production at the PC-386 computer.
