禾谷类作物产量构成因素对产量的影响研究报道甚多,但大麦的研究却不多见.本试验的目的是探索诸产量构成因素在大麦产量形成中的相互关系,为高产栽培提供依据.材料和方法试验于1981～1983年在扬州江苏农学院实验农场进行.供试品种为盐辐矮早三,处理设每亩12,15,18,21和24万基本苗,随机排列,重复三次,小区面积0.015亩,测产面积0.01亩.前茬中稻,地力中上等,采取促控促的施肥法,亩施肥折合纯氮32斤.
There are many reports on the effects of yield components of cereal crops on yield, but the research on barley is rare.The purpose of this experiment is to explore the relationship between yield components in the formation of barley yield and provide the basis for high-yielding cultivation.Materials And method test were carried out in experimental farm of Jiangsu Agricultural College in Yangzhou from 1981 to 1983. The test varieties were salt dwarf varieties as early as three days and the treatment of 12,15,18,21 and 240,000 basic seedlings per acre were randomly arranged and repeated three times, The plot area of 0.015 acres, measuring an area of 0.01 acres. Pre-crop middle rice, superior ground force, to promote the promotion of fertilization, fertilization equivalent to 32 kg of pure nitrogen.
