Calotropis gigantea (school name: calotropis gigantea (L.) Dry.ex Ait.f.) is an upright shrub, up to 3 meters, whole plant with milk; the stems are yellow and white, the branches are thick and strong, and the young branch parts are grey and white fluff. The leaf is oval or elliptical, and has a length of 8-20 cm and a width of 3.5-9.5 cm. The shape of the umbrella inflorescence, axillary growth and top growth; inflorescences and peduncles are colored grey and white with villi. Setting a whole length; the seeds are wide oval, 5mm long and 3 mm wide; the seed hair length is 2.5 cm. The flower and fruit period is almost year round. The stem skin fiber can be used for paper making, rope making and artificial cotton, and bast fiber fabrics and sacks are woven; the wool can be used as velvet raw material and filler. The milk of the stem and leaf is toxic, contains a plurality of cardiac glycosides, and can be used for treating skin diseases, dysentery, rheumatism and bronchitis; pi can treat tinea. The milk can be used as gum material after drying, and can also be used for preparing tanning material and yellow dye. The whole plant can be used as green manure.

Experimental example 1
The cuttings of examples 4 to 6 and comparative examples 1 to 5 were examined after 10 days of cutting, and the average root number, average root length, nursery rate and survival rate after 3 months of transplanting were measured.
Root number means the number of white roots (roots) protruding from the base of the slip; average root number = root number sum of root stem segments/root stem segment number 100%; root length means the length (cm) of the longest root system measured from the root of the slip; average root length = root length sum of root stem segments/root stem segment number 100%; rooting rate = rooting stem/100 x 100%; nursery rate = suitable transplanted stem segments/100 x 100%; survival = surviving stem segments after transplanting/stem segments suitable for transplanting 100%. The specific results are shown in Table 1.
TABLE 1 Effect of different treatments on Calotropis gigantea cutting parameters
As shown in Table 1, the cutting method of Calotropis gigantea of the present invention was significantly improved in average root number, average root length, rooting rate, nursery rate and survival rate compared with comparative examples 1 to 5 after cutting for 10 days.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
