Hybrid liriodendron chinense cutting breeding method

Abstract

The invention discloses a hybrid liriodendron chinense cutting breeding method. A spraying slotting machine with full illumination and unblocked draining is used, the bottom layer of the slotting machine is laid with cobblestones, and gasp between the cobblestones are filled with sandstones; the middle layer is laid with river sand; the top layer is laid with a cutting matrix, and a bactericide isadded to the cutting matrix before cutting; when a cutting slip is cut, the notch in the lower end is flat, and the notch in the upper end is flat or inclined; the lower end of the cutting clip is immersed with a rooting liquid or dipped with rooting powder; a needed jack is made in the slotting machine in advance, and the lower end of the cutting clip is inserted into the jack; spraying and watering are carried out after cutting immediately, watering is carried out in small amount and frequently, it is ensured that there are water drops on leaves of the cutting clip but there is no accumulated water in the cutting matrix; and the leaves of the cutting clip are sprayed with foliar fertilizers regularly. The rooting rate and survival rate of the hybrid liriodendron chinense can be improvedgreatly, and the method also has the advantages of fast growth, high ornamental value, high stress resistance, high environmental protection performance and wide application prospects.
