扶桑又名木槿,系锦蔡科木槿属的常绿灌木或小乔木。扶桑枝叶繁茂,叶片油绿,花大色艳,花期较长,深受人们喜爱。扶桑的繁殖主要采用扦插的方法,为确保扦插成活率高,必须创造扦插的适宜条件,主要是温度,以20—25℃扦插,生根最快。因此,在自然条件下,6—7月份用当年生长发育充实的枝条扦插最易成活。方法是:选健壮,无病虫害、芽部饱满、节间短的枝条,剪10—15厘米长,做插穗切口安倾斜平滑并靠近节基部。将下部叶片剪掉,保留上部1—2片叶,如选用带有顶芽的插穗就更易成活。扦插可选用河沙或其他排水性良好、疏松通气材料做介质,将介质洗净消毒,以防感染腐烂;插床厚以15厘米左右为好。扦插时用铁丝或小棍在插床上扎孔,然后将插穗插入,插穗间距以不接触为原则,深2—3厘米,插后要喷水,以使插穗与砂
Hibiscus, also known as hibiscus, is the evergreen shrub or small tree belonging to the genus Hibiscus. Fuso lush foliage, green leaves, large flowers Yan, flowering longer, deeply loved by people. Hibiscus reproductive mainly using cutting methods, in order to ensure the survival rate of cutting high, we must create the appropriate cutting conditions, mainly temperature, to 20-25 ℃ cutting, rooting the fastest. Therefore, in natural conditions, June-July with the full growth and development of the branches cuttings most likely to survive. The method is: Choose robust, no pests, Bud Department plump, short internode branches, cut 10-15 cm long, do cutting incision Ans slope smooth and close to the base of the festival. The lower part of the leaves cut off, retaining the upper 1-2 leaves, such as the use of cuttings with the top bud is more likely to survive. Cutting sand or other drainage can be selected with good drainage, loose ventilation medium to do media washing and disinfection to prevent infection decay; bed thickness of about 15 cm is better. Cuttings with wire or stick in the slotted hole, and then insert the cuttings, cuttings to the principle of non-contact spacing, 2-3 cm deep, after the plug to water, so cuttings and sand
