中文摘要	为研究AquaCrop模型模拟旱地全膜双垄沟栽培模式的适用性,寻求最佳农艺管理措施,本研究选择2014和2015年玉米施氮梯度试验数据对模型中品种和胁迫参数进行率定和验证,并模拟不同管理措施水平下产量变化趋势.结果表明:所有处理实测和模拟产量的平均根方误差(RMSE)、标准化均方根误差(NRMSE)和符合度指数(d)分别为717 kg · hm~(-2)、10.0%和0.96,总生物量的RMSE、NRMSE和d分别为951 kg · hm~(-2)、6.5%和0.98,能够较好的反映旱地全膜双垄沟玉米的栽培特性;在冠层覆盖度和生物量动态模拟分析中得出施氮270 kg N · hm~(-2)时的拟合度最好,随着氮肥的胁迫增加,模拟精度逐渐降低;甘肃中部地区全膜双垄沟玉米栽培模式中最佳播种期在4月下旬至5月上旬,播种密度为45000~65000株· hm~(-2),生育期时长在130~145 d,施氮量为240-280 kg · hm~(-2).本研究结果对AcquaCrop模型在甘肃干旱区域的应用具有一定参考价值,而且有助于农业栽培技术的转化和推广.
英文摘要	In order to study the applicability of AquaCrop model for simulating dryland whole plastic-film mulching in double ridges cultivation mode and to find the best agronomic management measures, the data of nitrogen gradient test in 2014 and 2015 were selected to validate the variety and stress parameters in the model. The change trends of yield were simulated under different management measures. The results showed that the root mean square error (RMSE), normalized root mean square error (NRMSE) and the compliance index (d) of the measured and simulated production for all treatments were 717 kg · hm~(-2), 10.0% and 0.96, respectively, the RMSE, NRMSE and d of the total biomass were 951 kg · hm~(-2), 6.5% and 0.98,respectively, which indicated that the cultivation characteristics of the whole plastic-film mulching on double ridges maize in the dryland could be well reflected. The best fitting degree was 270 kg N · hm~(-2) from dynamic simulation analysis of canopy cover degrees and biomass, and with the increase of N stress,the simulation accuracy gradually declined. The best sowing time of the whole plastic-film mulching on double ridges maize in the middle part of Gansu Province was from late April to early May, the seeding density was 45000-65000 plants · hm~(-2), the growth period was 130-145 days, and the nitrogen application rate was 240-280 kg · hm~(-2). The results of this study had a certain reference value for the application of AcquaCrop model in arid region of Gansu, and would contribute to the transformation and popularization of agricultural cultivation techniques.
