摘要
在呼和浩特市开展对空气中的花粉调查工作尚属首次.通过试验表明,呼和浩特市区主要的木本植物是榆属(Ulmus sp.)、杨属(Populus sp.)、柳属(Salix sp.)、松属(Pinus sp.)、侧柏属(Platycladus sp.)、丁香属(Syringa sp.)等等.它们的花粉多在4、5、6三个月中出现在空气中;而草本植物主要是豆科(Leguminoae)、菊科(Compositae)、禾本科(Gramineae)、莎草科(Cyperaceae)、藜科(Chen-opodiaceae)、蓼科(Polygonaceae)等等。它们的花粉多在7、8两个月中集中出现.所以,我们认为市区空气中的花粉组合,基本上能够反映出市内植物的种类和开花期.
This is the first report on pollens in the air over Huhehaote c- ity。The result showed that there were various kinds of pollens th- ere,such as pollens of Ulmus sp.,Populus sp.。 Salix sp.,Pinus s- p.,Platycladus sp.,Syringa sp.trees and pollens of Leguminosae, Compositae,Gramineae,Cyperaceae,Chenopodiaxeae,Polygonaceae herbs.Tree pollens appeared on April,May aud June.Herb pollens appeared on July and august.The composition of pollens,in gener- al,reflected the kinds of plants and their flowering stages.
