在茶花、月季、菊花、杜鹃等许多花木中,通过嫁接均能使一树开出多种色彩的花。那么,能否让冬季开花的一品红也一树开出几种颜色的“花”来?实践证明是可行的。一、选砧木。选一健壮的一品红植株,于立秋前后留10cm高桩头,剪去主干、侧枝,每隔一星期施一次薄肥,共施三次。至9月下旬形成了多侧枝的植株,用其作砧木。立秋后的天气非常适合一品红的生长,待侧枝长到5cm～8cm时,即可嫁接各种颜色的一品红。二、取接穗。用一大口容器(如饭盒、小脸盆之类的盛水工具),装上5cm深的清洁水备用。将不同颜色母本上一品红嫩枝头(约3cm长、粗细与砧木侧枝相当)用刀割下,让其站立于清洁水中,供嫁接时随用随取。三、嫁接。先用锋利刀片将接穗削成2cm长的斜面,再放入水中,接着尽快将砧木也削成2cm的斜面,取出削好的接穗,甩干水份,紧贴于砧木上(这时砧木斜面还在冒白浆,正好对接穗切口起着消毒作用),对准形成层,用清洁的薄塑料带
In Camellia, Rose, Chrysanthemum, Rhododendron and many other flowers, through grafting can make a tree out of a variety of colors of flowers. So, can make the winter flowering poinsettia tree out of several colors “flower ” come? Practice has proved feasible. First, choose the stock. Choose a robust poinsettia plant, stay in the autumn before and after 10cm high pile head, cut off the trunk, collateral, once every few weeks to apply a thin fat, co-administered three times. To late September formed a multi-lateral branches of plants, used as a rootstock. After the fall of the weather is very suitable for the growth of poinsettia until the branches grow to 5cm ~ 8cm, you can graft various colors of poinsettias. Second, take the scion. With a large container (such as lunch boxes, small washbasins like water-holding tools), fitted with 5cm deep clean water spare. Pointed shoots of poinsettia (ca. 3 cm in length, equivalent in thickness to rootstock branches) of the mother of different colors were cut with a knife and allowed to stand in clean water for use with the grafts. Third, grafting. First with a sharp blade scion cut into 2cm long bevel, and then into the water, and then cut the rootstock as quickly as 2cm incline, remove the cut scion, dry water, close to the rootstock (then rootstock bevel Still taking the white pulp, just cut the scissors play a disinfection role), aligned to form a layer, with a clean plastic sheeting
