介绍了利用中子仪或其他土壤水分测定仪器，定期测定农田土壤含水量，并通过PROBE软件进行综合分析，实现计划灌溉的方法。该方法可对作物水分利用和生产进行科学管理，使作物始终处于良好的供水状态，大幅度地提高农作物的产量和品质，节约水资源，提高灌溉水利用效率。PROBE系统还可用于快速、准确地分析作物的根系深度和吸水模式、土壤质地，减少无效排水、养分淋溶等。
This paper introduced the method of using neutron analyzer or other soil moisture measuring instrument to measure soil water content in farmland periodically and carrying out comprehensive analysis with PROBE software to realize planned irrigation. The method can manage the crop water use and production scientifically, so that the crop is always in a good water supply state, greatly improving crop yield and quality, saving water resources and improving irrigation water use efficiency. PROBE system can also be used to quickly and accurately analyze crop root depth and water absorption patterns, soil texture, reduce ineffective drainage, nutrient leaching and so on.
