Japanese bigleaf magnolia leaf cutting propagation method

Abstract

The invention discloses a Japanese bigleaf magnolia leaf cutting propagation method, which comprises the following steps: (1) preparation of cutting matrix and rooting agent solution, namely mixing perlite, vermiculite and yellow sand to prepare the cutting matrix, and adding the following raw materials by weight per 1kg: 50-200mg of vitamin C, 50-200mg of vitamin B2, 50-200mg of vitamin B6, 80-160 million units of gentamicin, 200-300mg of naphthalene acetic acid, and 200-300mg of indolebutyric acid, to prepare a rooting agent solution; (2) cutting propagation of leaves, namely shearing Japanese bigleaf magnolia leaves and soaking into the rooting agent solution, washing with clear water, and inserting the leaves into the cutting matrix; (3) fertilizer spraying of the leaves, namely spraying a rooting accelerator into the leaves once a week; and (4) transplanting, namely when new buds grow from leaves and at least two leaves grow, transplanting into a field. The Japanese bigleaf magnolia leaf cutting propagation method is short in propagation period, fast in growth propagation, and few in propagation materials, and has the time-saving and effort-saving effects.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation methods, in particular to a method for cutting and propagating leaves of Magnolia officinalis. Background technique [0002] Because the leaves of Magnolia officinalis contain substances that inhibit rooting such as tannin and turpentine, it is not easy to survive with cuttings of leaves, and the technology is difficult. So far, the cutting propagation method of Magnolia officinalis has not been promoted. application. [0003] Currently in practice, Japanese Magnolia officinalis is generally propagated by seeds. There are the following problems in seed propagation: (1) seed selection should be started in October of the first year, after seed treatment, sowing, seedling management and other processes, transplantation can only be done at the end of autumn of the following year, the time span is as long as one year, and the reproduction cycle is long; (2) It is time-consuming a...

Problems solved by technology

There are the following problems in seed propagation: (1) seed selection should be started in October of the first year, after seed treatment, sowing, seedling management and other processes, transplantation can only be done at the end of autumn of the following year, the time span is as long as one year, and the reproduction cycle is long; (2) It is time-consuming and labor-intensive to go through procedures such as selection of mother plants for seedlings, peeling of seeds soaked in warm water, selection of land for sowing, deep cultivation of land, basal fertilizer application, seedling management, and transplanting; (3) Only one batch can be bred each year , slow reproductive rate, low reproductive output
