基于根区水质模型的宁夏引黄灌区春玉米土壤水氮运移及淋溶过程模拟
Simulation of Soil Water and Nitrogen Migration and Leaching Process in the Yellow River Irrigation District of Ningxia for Spring Maize Based on RZWQM 2 Model
为研究宁夏引黄灌区不同施肥模式对土壤氮素运移的影响,应用根区水质模型(root zone water quality model-version 2, RZWQM 2)对宁夏引黄灌区春玉米农田水氮运移情况进行参数率定和数据验证。模拟结果表明:模型对土壤含水量模拟的均方根误差和平均相对误差变化范围分别为0.010 5~0.0291 g·g-1、5.58%~13.42%,模型对土壤硝态氮质量比模拟的均方根误差和平均相对误差变化范围分别为1.089 6~10.754 7 mg·kg-1、12.14%~42.30%,说明RZWQM 2模型在模拟宁夏引黄灌区土壤水氮运移方面具有较高的准确性。进一步模拟结果显示,在灌水量为533 mm、施氮量为300 kg·hm-2的条件下,能够维持作物高产的同时降低氮素淋溶损失,有利于进一步防控农业面源污染。
In order to investigate the impact of different fertilization patterns on soil nitrogen migration in the Yellow River Irrigation District of Ningxia, the root zone water quality model-version 2 (RZWQM 2) was applied to parameter calibration and data validation of soil water and nitrogen migration in spring maize fields. The simulation results indicate that the root mean square error and average relative error for soil moisture content simulation ranged from 0.010 5 to 0.029 1 g·g-1 and 5.58% to 13.42%, respectively, and those for soil nitrate nitrogen mass ratio ranged from 1.089 6 to 10.754 7 mg·kg-1 and 12.14% to 42.30%, respectively. The findings suggest that the RZWQM 2 model demonstrates high accuracy in simulating soil water-nitrogen migration in the Yellow River Irrigation District of Ningxia. Further simulation results show that under irrigation of 533 mm and nitrogen application of 300 kg·hm-2, it is possible to maintain high crop yields while reducing nitrogen leaching losses, which is beneficial for further controlling agricultural non-point source pollution.
