摘　　要：为提升高海拔地区微咸水利用效率,以青河县试验区种植的玉米、向日葵和马铃薯为对象,对比分析了磁化微咸水处理对各作物生长发育和产量的影响,进一步研究了磁化微咸水灌溉的向日葵生长模型,分析其生长特征与花盘直径的关系。结果表明:与常规灌溉大田试验相比,研究区3种作物生长发育特征值均显著增大,各作物产量分别提高了28.90%、18.27%和8.19%;磁化微咸水处理的向日葵生长发育各特征指标间相关性很强,建立了向日葵花盘直径关于其特征的多元线性回归模型,拟合系数R 2为0.942;在高海拔地区磁化微咸水灌溉能有效增强作物的生长发育特征,并提高其产量。研究结果可为高海拔灌区推广磁化微咸水设备提供理论依据。In order to improve the utilization efficiency of brackish water in high altitude areas,maize,sunflower and potato in Qinghe County experimental area were taken as research objects to analyze the effects of magnetized brackish water treatment on the growth,development and yield of crops.Then,the growth model of sunflower under magnetized brackish water irrigation was established to analyze the relationship between growth characteristics and flower disc diameter.The results showed that compared with the conventional irrigation field experiment,the growth and development characteristics of the three crops in the study area were significantly enhanced,and the yield of each crop was increased by 28.90%,18.27%and 8.19%,respectively.There was a strong correlation between the growth and development characteristics of the sunflower treated with magnetized brackish water.According to the multivariate linear regression model,the flower disc diameter was highly correlated with growth charateristics of sunflower,and the fitting coefficient R^(2)was 0.942.It is found that magnetized brackish water irrigation in high altitude areas can effectively enhance the growth characteristics of crops and increase their yield.The research results can provide a theoretical basis for the popularization of magnetized brackish water equipment in high altitude irrigation areas.
