摘要

为明确干旱区最优覆盖地膜类型和施氮制度，于内蒙古河套灌区木垒滩节水试验站进行为期2年的不同类型地膜覆盖农田不同施氮量试验。在高氮水平（传统施氮336 kg/hm2）下设置3种覆膜处理，包括塑料地膜（PFM3）、生物降解地膜（BFM3）和无膜覆盖处理（NFM3）；同时在生物降解地膜覆盖下设立3个施氮水平，包括中氮（BFM2，276 kg/hm2）、低氮（BFM1，216 kg/hm2）和不施氮（BFM0，0 kg/hm2），共6个处理。利用2年观测的产量、吸氮量和氮淋失量对DNDC模型进行率定和验证，并基于改进的TOPSIS方法对地膜类型和施肥制度进行优化。结果表明：DNDC模型对地膜覆盖及氮肥调控下作物生长与氮素迁移较为敏感，产量、吸氮量与氮淋失量模拟的EF与R2均大于0.83，NRMSE均小于20%，能够为作物生产力与资源利用进行预测和评估。随施氮量增加，所有覆膜处理的氮淋失量呈线性增加，当施氮量增加至106 kg/hm2时，氮肥利用率达到峰值；当施氮量增加至256 kg/hm2时，覆膜处理的产量不再发生明显变化，同时生物降解地膜的净收益也达到最大值；但其成本高，导致净收益比塑料地膜降低6.84%，比无膜覆盖处理提高3.17%。塑料地膜和生物降解地膜覆盖下的氮淋失量、氮肥利用率和产量无明显差异，均大于无膜覆盖处理，平均提高8.22%~26.69%。利用改进的TOPSIS法对产量、氮淋失量、残膜量、氮肥利用率和净收益5个方面进行综合评价，选出在生物降解地膜覆盖下施用氮肥231~256 kg/hm2是干旱地区较合理的覆膜施氮制度。

Abstract

In order to clarify the optimal film mulching type and nitrogen application system in arid areas

a two-year film mulching farmland fertilization experiment was conducted at Muleitan Water-saving Experimental Station in the Hetao Irrigation District

Inner Mongolia. Three mulching treatments were set at high nitrogen level (conventional nitrogen application 336 kg/hm2)

including plastic film (PFM3)

biodegradable film (BFM3) and no film mulching (NFM3); at the same time

three nitrogen levels were set up under biodegradable film mulching

including medium nitrogen (BFM2:276 kg/hm2)

low nitrogen (BFM1:216 kg/hm2) and no nitrogen (BFM0:0 kg/hm2)

making up to a total of six treatments. The DNDC model was calibrated and verified by the observed values of two-year yield

nitrogen uptake and leaching

and the film type and fertilization system were optimized based on the improved TOPSIS method. The results showed that the DNDC model was sensitive to crop growth and nitrogen migration under different film mulching and nitrogen regulations. The simulated EF and R2 of yield

nitrogen uptake and leaching were greater than 0.83

NRMSE were less than 20%

which could predict and evaluate crop productivity and resource utilization. With the increase of nitrogen application amount

the nitrogen leaching of each mulching treatment increased linearly. When nitrogen application amount increased to 106 kg/hm2

nitrogen use efficiency reached the peak; when the nitrogen application amount increased to 256 kg/hm2

the yield of mulching treatments did not change significantly. At the same time

the net income of BFM reached the maximum

but the cost of biodegradable film was high

which resulted in a net income of 6.84% lower than PFM and 3.17% higher than NFM. There was no significant difference in nitrogen leaching

use efficiency and yield between biodegradable film mulching and plastic film mulching

which were significantly higher than no film mulching

and the average increase from 8.22% to 26.69%. The improved TOPSIS method was used to comprehensively evaluate the yield

nitrogen leaching

use efficiency

residual film amount

and net income. The results showed that the application of 231 to 256 kg/hm2 nitrogen fertilizer was the most reasonable fertilization system under biodegradable film mulching in arid areas.
