池杉具有生长迅速,树干通直、园满,材质良好等优良特性。同时,它耐水湿,在积水1—3个月的情况下,尚能生长。因此,是沿海,沿湖、水网地区很有发展前途的树种。但是,池杉的种子比较缺乏,仅靠种子育苗,远远不能满足生产的需要。1973年底,我们从湖北引进池杉母本苗,于次年进行春插育苗试验,初步获得成功。扦插2400株,成活率达98％。苗木一般高达1.2米左右。 我们进行池杉春插育苗的初步作法体会是: Ipomoea with rapid growth, trunk straight, Park full, good material and other fine features. At the same time, it is resistant to water wet, in the case of water 1-3 months, still able to grow. Therefore, it is a very promising tree species along the coast, along the lake and the water network. However, the lack of seed of Ipomoea japonica, seedling alone, far from meeting the production needs. By the end of 1973, we introduced the seedling seedlings of Ipomoea aquatica from Hubei and carried out the experiment of spring-inserted seedling nurturing in the following year, initially achieving success. 2400 cutting, survival rate of 98%. Seedlings generally up to 1.2 meters. We carry out the preliminary practice of Isegami spring planting seedlings experience is:
