雪松为楹科常绿乔木,生长迅速,材质优良,树姿雄伟,是世界三大著名观赏树种之一。但因其大多雌雄异株,且开花时间不同,故结种量极少,种子繁烈不易推广。而采用硬枝扦插繁殖,则材料充足,成活率较高,可达90%以上。一、设置插床在排水良好的地方,用铁锹深翻,做成长1米、宽50厘米,深30厘米的插床,床内用洁净的河沙填满作为扦插基质。床上面用竹片和塑料薄膜搭成小拱棚,拱棚四周用土压盖以防棚内漏气。小拱棚上面用苇帘遮荫。在扦插之前床内基质要用0.5%的高锰酸钾水溶液进行清毒,以防病菌感染。
Cedar is an evergreen arbor division, rapid growth, good material, tree pose majestic, is one of the world’s three famous ornamental tree species. However, because most of its dioecious, and flowering time is different, so the amount of knot is minimal, the seed is not easy to promote. The use of hardwood cutting propagation, the material is sufficient, a higher survival rate, up to 90%. First, set the slot in a well-drained place, deep shovel with a shovel to do grow 1 meter, width 50 cm, 30 cm deep sockets, the bed filled with clean sand as a cutting substrate. Bed with bamboo and plastic sheeting made of small shed, arch surrounded by soil gland to prevent shed leakage. Small shed above the shade with reed curtain. Before cutting the bed with 0.5% aqueous solution of potassium permanganate to purify the virus to prevent bacteria infection.
