摘要
为研究不同处理条件下青稞产量的变化趋势,2021年以青稞品种“13-5171-7”“藏青16”和“13-6927”为试验材料,采用裂区设计,施肥量因素为主处理,设有2个水平,即:A1标准肥尿素8 kg、磷酸二铵10 kg;A2重施肥尿素12 kg、磷酸二铵15 kg;播种密度因素为副处理,设有3个水平,即:B116万株/667 m^(2)、B220万株/667 m^(2)、B324万株/667 m^(2),3次重复,结果表明:青稞试验材料在种植密度为20万株/667 m^(2),由于播前检测土壤肥力相对较弱,故青稞材料“13-5171-7”“藏青16”和“13-6927”在重施肥尿素12 kg、磷酸二铵15 kg的肥水条件下产量较高,“13-5171-7”的产量达到375.75 kg/667 m^(2);“藏青16”产量达到364.89 kg/667 m^(2);“13-6927”产量达到388.02 kg/667 m^(2),作物表现良好。
In order to study the variation trend of highland barley yield under different treatment conditions,in 2021,highland barley varieties‘13-5171-7’‘Zangqing 16’and‘13-6927’were used as test materials,and a split-plot design was adopted.The fertilizer application is the main factor with two levels,A1 standard fertilizer with 8 kilograms of urea and 10 kilograms of diamine;A2 heavy fertilization with 12 kilograms of urea and 15 kilograms of diamine.The sowing density factor is the side factor with 3 levels,B1160,000 plants/667 m^(2),B2200,000 plants/667 m^(2),B3240,000 plants/667 m^(2),repeated 3 times.The results show that the highland barley test material is planted at a density of 200,000 plants/667 m^(2).Because the soil fertility detected before sowing is relatively weak,the highland barley material‘13-5171-7’‘Zangqing 16’and‘13-6927’have higher yields under the conditions of heavy fertilization of 12 kg of urea and 15 kg of diamine.The yield of‘13-5171-7’reaches 375.75 kg/667 m^(2).The yield of‘Zangqing 16’reaches 364.89 kg/667 m^(2).The yield of‘13-6927’reached 388.02 kg/667 m^(2).All of these varieties performed well.
