落羽杉原名落羽松,系优良速生用材树种,在我国长江流域及珠江流域正在大力发展。但种子缺乏,多用扦插育苗。在毛主席革命路线指引下,根据我县育苗生产中存在的问题,我们进行了反复试验,使落羽杉扦插育苗的大田成苗率达90%以上,现将初步体会简介如下:一、圃地漫浸选择土层深厚排灌方便的微酸性砂壤土作苗圃。为消灭地下害虫,先将圃地水浸7天以上。一般地下害虫如白蚁、小地老虎、蛴螬、线虫等,可大部分死亡。有害病菌的菌丝自溶现象也很明显。圃地浸水与不浸水的插条成活
Taxodium distichum pine, the Department of excellent fast-growing timber species, in China’s Yangtze River and the Pearl River valley is developing vigorously. But the lack of seeds, multi-cutting seedlings. Under the guidance of Chairman Mao’s revolutionary line, according to the problems in our county’s seedling production, we conducted repeated tests so that the seedling yield of Taxodium distichum cuttage seedling reached more than 90%. The preliminary experience is as follows: First, Diffuse soaking selection of deep soil irrigation and drainage convenient acid soil loam for nursery. In order to eliminate underground pests, first flooding the garden for more than 7 days. Most of the underground pests such as termites, small tigers, slugs, nematodes, etc., most of them can die. Harmful bacteria mycelium autolysis phenomenon is also very obvious. Nursery water and not water cuttings survive
