池柏又名沼生落羽杉,是适于平原水乡地区生长的比较好的速生用材树种,它有速生、冠小、树干挺直、耐湿性强等特点,而且还具有早年开花结果的习性。但是,由于池柏的种源少,无性繁殖方法没有完全解决,自然授粉的种子孕育率低等原因,限制了苗木的大量供应,远远不能满足绿化的要求。鉴此,我们从去年开始探讨用人工授粉办法,以提高种子的授孕率,增加有性繁殖材料,经过一年多的摸索试验,取得了初步成果。 Ipomoea magna, also known as marsh Taxodium distichum, is suitable for the growth of plain water Township, a relatively good growing timber species, it has fast growing, small crown, trunk upright, moisture resistance and other characteristics, but also has early habits of flowering. However, due to the lack of provenance and the method of asexual reproduction, the natural breeding rate of pollinated seeds is low, limiting the large supply of seedlings and far from meeting the requirements of afforestation. In view of this, we started from last year to explore ways to use artificial pollination in order to increase the rate of seed germination and to increase sexual reproductive materials. After more than a year of groping experiments, preliminary results have been achieved.
