Cuttage method of Schefflera octophylla(Lour.)Harms

Abstract

The present invention relates to the field of a plant growing method. In a cuttage of schefflera octophylla harms, a half-lignified tress growing for one year is cut for 8 to 10cm, leaves at the lower part are pruned, and two leaves at the top are preserved; the tress is cut in turfy soil (for 20 to 40mm); the turfy soil is arranged in a plug; before cutting, the turfy soil is wetted completely; red mud and indoleacetic acid which are sterilized under high temperature are mixed into paste with the proportion of 1 to 1, and the paste is used as a rooting reagent; and when the tress is rooted, cutting slips are dipped with the rooting reagent. The temperature for cutting is 18 to 25 DEG C, after the cutting, the air humidity is kept 80 percent to 95 percent, and the tress is rooted within 4 to 6 weeks under the temperature of 20 DEG C. the present invention has the advantages and active effects that the cuttage ensures the rooting time of the schefflera octophylla harms is reduced from 45 days to 28 days, and the survival rate is improved from 60 percent to 98 percent.

Problems solved by technology

Because the sowing seedlings cannot keep the excellent traits of the parent plants such as macula, generally the horticultural varieties with macula cannot be raised by sowing, but can only be raised by cutting, layering, and branching.

Now there are cutting methods that generally use perlite as the cutting substrate, the cutting survival rate is low, and the rooting time is long
