Cuttage and seedling culture method without transplantation

Abstract

The invention relates to a transplant-free cutting propagation method. The method is characterized in that a cutting medium and a culture medium are held in different containers, wherein, the container holding the cutting medium is bottomless and the upper caliber of the container is identical with the lower caliber of the container, then the bottomless container holding the cutting medium is placed on a container with a bottom for holding the culture medium, the two containers are separated by a separation device to prevent pathogen in the culture medium from infecting the cutting medium, the separation device can be removed 10-20 days after cutting shoots root, new roots of the cutting shoots in the cutting medium stretch downwards into the culture medium without transplantation, and rooted plants absorb nutrition from the culture medium and continue to grow, thus ensuring 95-100% survival rate of the rooted plants.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for growing seedlings without transplanting cuttings. Background technique [0002] Green branch cuttings of plants, especially trees, are a very widely used method of asexual reproduction. The traditional method generally uses river sand, perlite, peat and other materials alone or mixed as the cutting substrate, inserts the vegetative organs (roots, stems, leaves) of the plant into the above substrate, and transplants them to the cuttings after the roots, stems or leaves take root. soil or in a container of nutrient soil. The first defect of this method is that the new root system of the plant will be damaged during the transplantation process, and the survival rate of the plant body will be reduced, especially for tree species that are difficult to take root (such as beech, red maple, etc.), the rooting time is long, the number of roots is small, and the r...

Problems solved by technology

The first defect of this method is that it will damage the new root system of the plant during the transplantation process and reduce the survival rate of the plant body, especially for tree species that are difficult to take root (such as beech, red maple, etc.), the rooting time is long, the number of roots is small, and the root system is weak , after the second transplantation, the survival rate of these difficult-to-root tree species is greatly reduced; the second is that after the plants take root in the above-mentioned matrix, they are transplanted into soil or a container containing nutrient soil, and it takes 15 to 30 days to slow down due to damage to the plant root system. Seedling stage, thereby affecting the growth of plants; third, plant transplantation needs a lot of manpower and material resources, time-consuming and labor-intensive
