Effects of Water-nitrogen Coupling on Highland Barley Quality and Yield in a High-altitude Cold Zone
To elucidate the relationship between the yield,quality,and irrigation and fertilization of highland barley,a two-year water-fertilizer cou-pling experiment was conducted in the high-altitude cold region in Tibet,using Zangqing3000 as the material.The results showed that under condi-tions of sufficient soil fertility,irrigation had a significant impact on the yield,grain starch content,grain amylopectin content,and gluten content of Zangqing3000.Nitrogen application had a significant impact on the yield and gluten content of Zangqing3000.Irrigation and nitrogen application had significant interactive effects on the grain protein content,gluten content,and stability of Zangqing3000.Under the conditions of this experiment,when the grain was irrigated once at the jointing stage,heading stage,and filling stage,each time with 40 m3/667m2 of water and 180 kg/hm2 of nitro-gen application,the yield of Zangqing3000 was the highest.
