苗圃的园艺工人一般是利用根和芽繁殖玫瑰苗木。插条育苗在5～7月间进行,11月萌芽。用这种方法生产苗木至少要一年才能采花。采用一种称为“stentiug”的快速繁殖枝(Vande Pol和Breukelaar 1982),在温室的喷水条件下,嫁接和发根同时进行,这样经过4～6周育成的苗木只需生长4个月便可采花。用这种方法每平方米五周内便可生产20O～400株苗木(Grueber和 The nursery horticultural workers usually use the roots and buds to breed rose seedlings. Cuttings nursery in 5 to 7 months, bud in November. It takes at least one year to produce seedlings by this method. Using a rapid breeding branch called “stentiug” (Vande Pol and Breukelaar 1982), grafting and rooting are carried out simultaneously in a greenhouse under sprinkling conditions so that seedlings grown after 4 to 6 weeks grow only 4 Months can be taken. In this way, 20O ~ 400 seedlings can be produced within five weeks per square meter (Grueber and
