上海市郊国营农场大麦产量较低,特别是近几年黄花叶病栽培面积逐渐扩大,重病区减产幅度可达20～40％,迫使大麦面积逐渐减少,影响大麦生产。经多年试验,“沪麦10号”(85—10)的丰产性和抗病性表现突出。1985年秋我们组织跃进等农场科研站对“沪麦10号”进行了播期、密度、不同叶龄期施氮肥等配套试验,现简述如下: 一、播期试验试验从10月20日开始,至11月24日,每隔5天播一期,共8期。随机区组排列,重复3次,小区面积0.05亩。经两年试验,结果基本一致,产量以11月4日播种的最高,10月30日、11月9、14日播种的产量也较高。除此,过迟、过早播种的产量都
The output of barley in state-owned farms in the suburbs of Shanghai is relatively low. Especially in recent years, the cultivated area of yellow mosaic has gradually expanded, and the rate of decrease in serious wards can reach 20-40%, forcing the area of barley to gradually decrease, affecting the production of barley. After many years of experiments, “Shanghai wheat 10” (85-10) outstanding performance and disease resistance. The autumn of 1985 we organized leap and other farm research stations on the “Shanghai wheat 10” sowing date, density, nitrogen fertilizer and other leaf age supporting experiments, are summarized as follows: First, the sowing test from October 20 , To November 24, every 5 days broadcast a total of eight. Random block arrangement, repeated 3 times, the plot area of 0.05 acres. After two years of experiments, the results are basically the same, with the highest yield sowing on November 4 and the higher sowing on October 30, November 9 and 14. In addition, too late, too early sowing output all
