池杉劈根育苗是利用池杉萌蘖性强的特点,在冬春将当年生繁殖的小苗掘起后,再在根基以上5—6厘米处进行截于。其茎部供作春插插穗,根茎部用锋利刀具分1/2或1/4劈开。增加池杉繁殖数量。1975年春,我们将85株池杉苗劈成200株。于8月31日调查,成活了162株,成活率达81％,平均生长量为64厘米,苗木长势与一般截干苗没有差别,具体做法如下:
Ipomoea plicata root nursery is the use of Ipomoea strong sprouting characteristics, in the spring and winter will be the year after the breeding of young seedlings digging, and then in the roots above 5-6 cm at the cut. Its stems for spring cuttings, rhizomes with sharp knife points 1/2 or 1/4 split. Increase the number of sycamore breeding. In the spring of 1975, we chopged 85 plantation seedlings into 200. On August 31 survey, 162 survived, the survival rate of 81%, the average growth of 64 cm, seedling growth and general truncated stem no difference, the specific practices are as follows:
