全国大麦品种类型在江苏沿海生态条件下的适应性研究

Studies on adaptability of barley variety type in the whole country under the ecological condition of the coastal areas Jiang su

在盐城沿海生态条件下,气象三要素(光、温、水)对大麦生育极为有利。全国大麦品种在本区适应性表现,二棱大麦早熟、产量籽粒品质比较稳定,宜啤酒大麦选用;多棱大麦穗大粒多,增产潜力大,饲料大麦,要求更高档次的产量可选用。来自全国各地的品种均能正常抽穗成熟,熟期随纬度(海拔)升高,复种指数降低而相应推迟。苗期生长习性,来自冬播大麦区域内品种,低纬春性型品种逐渐向中纬的半冬、冬性型过渡,越过冬播大麦区为限,均为春性型。

Under the ecological condition of the coastal a sreas Yangcheng, Threeessential factors (temperature, light, water) in the meteorology are of gre-at advantage to barley growth and development. The adaptability of wholecountry barley variety in the areas show: two-rowed barley is earliness, highgrain weight, more stable to yield and grain qulity, malting barley ought toselect two-rowed variety; six-rowed barley is large ear, more grains and greatpotentiality of increase production, feed barley may select six-rowed variety;alll variety are normal heading and mature; mature period vary with latitude,elevation and multiple cropping index. Growth habit gradully change fromspring type in lowlatitude to semi-winter, winter type in middle latituadeiuautumn-sowing areas, it is spring type in spring-sowing aresa.
