摘要
对甘肃省境内主要类型草场的主要野生牧草种质资源分布和现状进行了调查。调查范围涉及河西走廊、祁连山区、甘南高原、黄土高原和陇南西秦岭山区等不同地貌类型的温带阔叶林、温带针叶林、温带典型草原、温带草甸草原、高寒草甸、高寒灌丛、盐化草甸、沼泽化草甸、温带灌丛、温带荒漠等植被型。对不同植被的38个样点植物群落的主要成分进行了记载分析,了解了以豆科、禾本科为主的各植物种的分布现状。在调查的过程中共涉及植物157种,分属14科50属,其中草甸种有90余种,草原种有50余种,荒漠种有10余种;禾本科植物59种,豆科植物19种。调查采集了以豆科和禾本科为主的55个可作为牧草利用的植物种的96份种质材料,并采集了106份植物标本。作为种质材料,保存了可作为牧草利用的植物种子146份1 050 g。
The investigation on the distribution and condition of the germplasm resources of wild forage grasses in the various pastures in Gansu province was conducted. The area investigated covered the Hexi Corridor, Qilian Mountains, Gannan Highland, Loess Plateau and the West Qinling Mountains area, including various vegetation types, i.e. the temperate broad-leave forest, temperate coniferous forest, steppe, meadow steppe, alpine meadow, alpine shrub, halophyte meadow, marsh thicket and temperate desert. The investigation recorded and studied the key components of 38 plant communities in various vegetations and learned the distribution of various plant species, mainly of legume and gramineous families. 157 species of 50 genera of 14 families were involved in the investigation, among which 90 odd were meadow species, more than 50 were steppe species and more than 10 were desert species; 59 were gramineous species and 19 were legume and 106 plant-specimen were collected. 1 105 g seeds of 146 accesses as germplasm materials were preserved.
