基于WHCNS_Rice模型的水稻节水灌溉模式模拟与评价
Simulation and evaluation of water-saving irrigation modes for rice based on WHCNS_Rice model
摘要
Abstract
To optimize the water and fertilizer saving irrigation modes to provide beneficial theoretical support for rice growing area in southern China,a field experiment was conducted from July 8 to Octo-ber 20,2022 in the water-saving park of Hohai University,Jiangning District,Nanjing,Jiangsu Pro-vince.Based on the experimental data,the parameters of the WHCNS_Rice model were calibrated and verified.To address the goals of water and fertilizer saving,a comprehensive evaluation index system was established by selecting four indexes,namely,water consumption intensity,evapotranspiration of rice,leakage of rice field and nitrate leaching loss.The calibrated model was then used to simulate the water depth and nitrate nitrogen concentration changes of paddy fields under three water-saving irriga-tion models:shallow water frequent irrigation,shallow moisture regulation and control irrigation.By comparing the difference of nitrogen transfer and transformation under different irrigation modes,the water saving and fertilizer saving effects of the three water-saving irrigation modes were analyzed.The results show that the calibrated WHCNS_Rice model can be used to simulate the dynamic changes in water levels and nitrate concentration in rice fields.The water consumption patterns of FSI and WSI modes show a high degree of agreement,while CI model has a very low agreement with them.Com-pared with FSI and WSI,CI model can reduce water leakage by 64.27％-73.65％and nitrate nitrogen leaching loss by 84.80％-93.28％.The entropy weight TOPSIS method is used to evaluate and optimize the water-saving irrigation modes for rice.The results show that controlled irrigation is the optimal irri-gation mode under the indexes of water-saving and fertilizer saving.关键词
