基于经典质量法的栓皮栎幼苗精准灌溉制度的制定

Formulation and Design for Accurate Irrigation System of Quercus variabilis Seedling

采用经典质量法分析了5个水分梯度(90%、70%、60%、50%和40%)下北京地区栓皮栎盆栽幼苗的水分需求规律,通过统计分析法筛选出最佳水分梯度为60%,以此梯度下苗木的需水量为标准制定灌溉制度,并利用GIS技术建立灌溉模块,将气象、需水量等数据输入计算机系统对苗木的田间推广进行具体布设,并对其水分需求进行实时监测和控制,以此达到苗木的精准培育和节水目的。

We used the classical gravimetric method to analyze the water consumption law of Quercus variabilis seedlings in five moisture content gradients （90%, 70%, 60%, 50% and 40% ） in Beijing area, achieved the optimum moisture gradient （60%） through the statistical analysis method, and used the consumption water of this gradient as the standard for seedling to establish the irrigation system for the field promotion. By using GIS to establish the irrigation module, we input the mete- orological data, water demand data to the computer systems for planting the seedlings with a specific layout, and monitored and controlled its water requirements for real-time to achieve the purpose of precise nurturing seedlings and water-saving.
