泾大一号大麦新品系是我县罗泾公社张近林同志1976年从早熟3号大麦中系统选育的。该品系为二棱大麦春性,较耐黄花叶病毒病。经三年病田试种,产量比早熟3号增产10～20％。1981年我县推广种植约7000亩。1979～1980年,县品比试验结果,泾大一号平均亩产583.7斤,比对照早熟3号增产22.6％、1980～1981年上海市品比试验产量居首位。市生产试验6个点中居首位的有4个。 1980年春调查泾大一号耐病情况,施肥不足的田,株发病率在72％,在播期正常、病因、施肥足的情况下,株发病率在19—25％。据1980～1981年市大麦品比试验调查黄花叶病发病情况,第一次
Jing new big barley number is Comrade Zhang Jinlin commune in Luojing County in 1976 from the early maturing 3 barley system breeding. The line of barley spring barley, yellow mosaic virus-resistant disease. After three years of field trial, the yield was increased by 10 ~ 20% compared with that of early maturity. In 1981 my county to promote planting about 7000 acres. From 1979 to 1980, the county-specific product test showed that the average output of Jing-1 was 583.7 kg per mu, which was 22.6% higher than that of the control-early-matured No.3. From 1980 to 1981, the output of Shanghai-specific products ranked first. City production test 6 points in the top four. In the spring of 1980, the disease-resistant status of Jing 1 was investigated. The field and strain with insufficient fertilization were at 72%. The incidence rate was 19-25% under the condition of normal sowing date, etiology and fertilization. According to the 1980-1981 municipal barley product testing yellow mosaic disease incidence, for the first time
