山西省野葛种质资源分布与植物学性状研究

Study on Distribution and Botany Characteristics of Pueraria lobata( Willd) Ohwi from Shanxi

了解山西省野葛种质资源的分布状况、群落组成以及植物学特性,为晋产野葛资源的挖掘、保护和可持续利用提供参考依据。对山西境内12个产地野葛的植物学性状及生长环境进行实地调查。结果表明,山西省野葛种质资源主要分布于晋南的中条山区域和晋北的太行山区域。从水平分布看,山西野葛主要分布于34°47＇04.77″-39°31＇05.23″N,110°30＇17.80″-114°33＇18.24″E;垂直分布介于730-1240 m之间,以海拔730-950 m最为常见。山西野葛生长的区域年均降水量介于400-800 mm之间,年均温度为6.8-14℃。山西野葛的群落组成较为单一,大部分伴随其生长的是较矮的灌木丛,少部分伴随有杨树、刺槐等。根据生态环境的不同,可将山西野葛大致分为疏林灌木型、河道草地型和砂质土壤型3种类型。

To understand the germplasm resources distribution,community composition and the botany characteristics of Pueraria lobata（ Willd） Ohwi from Shanxi Province provides some references for the protection and sustainable utilization of resources. The environment and botany properties of Pueraria lobata（ Willd） Ohwi which were taken from the 12 different sources of Shanxi Province were investigated. The results showed that the germplasm resources were mainly distributed in Zhongtiao mountain and Taihang mountain of Shanxi Province. From the point of horizontal distribution,the range was between 34°47＇04. 77″-39°31＇05. 23″N and 110°30＇17. 80″-114°33＇18. 24″E.With the vertical distribution between 730-1240 m,an elevation of 730-950 m was the most common. The annual rainfall of the growth area was between 400-800 mm,average annual temperature 6. 8-14 ℃. The community composition was relatively single,most growth with shorter brush,only a small number with Pterocarya stenoptera or Robinia pseudoacacia. Depending on the ecological environment,the plant were roughly divided into three kinds of types such as savanna shrub grassland type,channel type and sandy soil type.
