基于养分平衡施肥法的配方施肥系统设计

为解决化肥的过量使用,减少环境污染,提倡精准施肥。本研究利用养分平衡施肥法与计算机Visual Basic语言相结合,编制配方施肥系统。通过作物需肥量参数的计算、土壤供肥量参数的计算、肥料利用率参数的计算、目标产量参数的计算和有效养分含量参数的计算5部分,输入系统计算各肥料施肥量。达到了产量不变的前提下,提供最科学与最小的施肥量。本系统可以准确、高效、科学的完成配方施肥工作。

Design of Formula Fertilization System Based on Nutrient Balance Fertilization Method

To solve the excessive use of chemical fertilizer and reduce environmental pollution, we promote precise fertilization. In this study, a formula fertilization system was developed by using Visual Basic language and nutrient balance fertilization method, fertilizer application was calculated by five parameters: fertilizer demand, soil fertilizer supply, fertilizer utilization, target yield and available nutrient content in fertilizer. Under the premise of constant yield, it provided the most scientific and minimum fertilizer application. This system could accurately, efficiently and scientifically complete the work of formula fertilization.
