龙柏(Sabina chinensis var. kaizuka)是珍贵的庭园观赏树种。为培育更多的龙柏树苗,我们在向阳排水良好的地块做高20—30厘米、宽1米的高畦,畦内铺放从松树林下挖取的松针土做插壤。插枝采集半木质化、生长健壮的一年生枝,枝长15—25厘米。上端保留小枝,下部小枝剪除,剪口要平。插枝用100ppm α-萘乙酸浸泡基部18—20小时。插枝入土2/3,行距10厘米,株距5厘米,插后浇一次透水。床面加盖薄膜和苇帘,透光度50％左右,床内温度超过26℃时,应揭开两头通风。
Sabina chinensis var. Kaizuka is a valuable ornamental tree species. To cultivate cypress trees, we planted 20-30 cm high and 1 meter wide high above the well-drained area of the sunny side. We planted the loosers of pine needles excavated from pine forests. Cuttings collected semi-lignified, robust annual branch growth, length 15-25 cm. Leave the upper branch, lower branch cut off, cut to be flat. The shoots were soaked with 100 ppm alpha-naphthaleneacetic acid for 18-20 hours. Cuttings into the soil 2/3, row spacing 10 cm, spacing 5 cm, after pouring a pouring water. Bed covered with film and reed curtain, transmittance of about 50%, when the bed temperature exceeds 26 ℃, should be opened to both ends of the ventilation.
