根据黍稷品种的生态特点,山西省分为三个生态区,即晋北特早熟生态区、晋中早熟生态区、晋南中早熟生态区、各个生态区内黍稷品种的生育期、穗型、茎秆高度、花序色、粒色、单株粒重、千粒重、茎叶茸毛、粒色等各有差异。通过对黍稷品种生态型的研究,可以了解黍稷品种生长发育和环境条件相互关系的规律性,从而为黍稷高产栽培、引种、调种、杂种优势利用和创造黍稷品种新类型提供科学依据。
According to the ecological characteristics of jujube cultivars, Shanxi Province is divided into three ecotopes, namely the Jinbei premature ecoregion, the Jinzhong precocious ecotope, the Jinnan middle and early maturing ecotope, the growing period of the jujube breed Type, height of stalk, inflorescence color, grain color, grain weight of one plant, grain weight of one thousand, stem hair, grain color and so on. By studying the ecotypes of the breed, we can understand the regularity of the relationship between the breed and development of the breed and the environmental conditions so as to provide science for the high-yielding cultivation, introduction, breeding, utilization of heterosis and creation of new types of breed. in accordance with.
