不同矿化度灌溉水对春小麦种子萌发特性的影响
Effects of Irrigation Waterwith Different Contents of Total Dissolved Solidson the Germination Characteristics of Spring Wheat Seeds
摘要
Abstract
In order to solve the issue of water shortage,explore the response of wheat seed germination to different water quality,germination experiment was conducted on 3 spring wheat varieties(Xinchun 15,Xinchun 8 and Xinchun 6)seeds in 4 different germination water with diverse contents of total dissolved solids(distilled water 0 mg/L,tap water 495 mg/L,green irrigation water 772 mg/L and brackish well water 4 152 mg/L),germination and root growth parameters of different varieties were determined and analyzed.The results showed that with the rise of salinity,three spring wheat varieties germination parameters were decreased.According to the principal component analysis,7 wheat germination and root growth parameters were simplified to two key factors,and a comprehensive evaluation system was established.The top three treatments were:Xinchun 15 with distilled water,Xinchun 15 withtap water and Xinchun 8 with distilled water.The comprehensive scores of principal components were 1.56,0.81 and 0.53,respectively,and the comprehensive ranking of Xinchun 6 with brackish well water was the lowest.According to the comprehensive analysis,the comprehensive performance of Xinchun 15 with distilled water was the best,but the irrigation cost of using distilled water is too high.Due to the strongest salt tolerance of Xinchun 15,thisvariety can be promotedin localproduction.Combined with the actual situation,it is recommended to use green irrigation water to completely or partially replace agricultural irrigation water for irrigation in local spring wheat production.关键词
