| 摘 要： | 银胶菊在路边、沟渠边、荒地、林地中发生较普遍,种群数量较大,其种子多集中于表土层。农田、果园中银胶菊发生面积较小,种群数量较少,其种子多集中在表土下1.5～10 cm处。银胶菊种子在土表0～0.5 cm处出苗率较高,而埋深1.5 cm以下,种子不能发芽出土。

| Abstract: | In such habitats as roadside, ditch, waste land and forest lang, there were denser population of Parthenium hys- terophorus, and the seeds usually gathered in soil surface. However in farming land and orchards, its occurrence area and population were smaller,and the seeds were deeply buried underground 1.5 - 10 cm. Seeds buried in 1.5 - 10 cm topsoil presented a higher emergence rate of seedling. When the seeds buried deeply under 1.5 cm topsoil, the seeds germination was acturally inhibitted. |
