自1959年以来,我厂科研组作了防除茶树上的苔藓地衣的试验研究。苔藓,在植物分类学上属于高等植物,它们的特征,在于其主要的营养体是具有绿色的配子体,多数苔藓植物具有分化的茎和叶,仅有假根,其中也有部分无根茎叶的分化。这类植物的世代交替,既可以孢子体通过形成孢子而后产生配子体;又能经过配子的结合而由配子体产生孢子。所以在它们的生活史中,也可能在配子体产生孢子之前由营养繁殖而形成配子体。
Since 1959, our plant research group made a pilot study on the control of moss lichen on tea trees. Moss, belonging to higher plants in phyto-taxonomy, are characterized by their main vegetative body having green gametophytes, the majority of bryophytes having differentiated stems and leaves, and only pseudotropes, of which some also have no root-and-shoot differentiation . Alternate generation of such plants, both by the sporulation of sporophytes and then produce gametophyte; but also through the combination of gametophyte spores generated from gametophyte. Therefore, in their life history, it is also possible to form gametophytes by vegetative propagation before the gametophyte produces spores.
