Problems solved by technology

Its disadvantages are that the branches from the underground horizontal stems of the parent body have no vertical tap roots, the survival rate of transplanting is low, the plants have weak drought and cold resistance, and poor adaptability
[0009] It can be seen that, on the one hand, natural reproduction is not conducive to standardized production, and the product quality is unstable. On the other hand, the existing asexual reproduction technology has many shortcomings, which greatly limit the development of this industry.

Embodiment 1

[0039] 1. Dig ditches on the land around the bottom of the sprouting branches of Schisandra chinensis, press the sprouting branches as layering strips in the ditch and fill up the ditch, leaving the front part of the new shoots exposed to the ground; topping the plants; The tiller branch is separated from the mother tree from the base;

[0040] 2. In the spring of the following year, dig out the rooted layering strips, cut them into single-bud branches with roots, and cultivate them with the bud eyes facing upwards. Cover the buds with soil and apply 800 times more antimycin once for shade; remove the shade after the seedlings survive .

Embodiment 2

[0042] 1. Management of shoots

[0043] The Schisandra chinensis plants with good growth are used to cultivate strong sprouting branches at the base of the mother tree to ensure the vigorous growth of the sprouting branches. Prepare the layering propagation operation 2 months before the mother tree leaves.

[0044] 2. Sprout branch layering

[0045] Dig a deep ditch from the surrounding land below the cultivated sprout tiller, press the sprout tiller in the ditch, fill it up with fine soil, and the front end of the new shoot is exposed to the ground. 30 days before plant defoliation, pinch the heart to control growth. After the plant enters the dormant period, cut off the shoots from the base and separate from the mother tree.

[0046] 3. Single bud propagation

[0047] After the soil thaws in spring, dig out the rooted layering strips, cut them into single-bud branches with roots, cultivate them with the bud eyes facing upwards, cover the buds with soil and apply 1000 tim...

Embodiment 3

[0049] 1. Management of shoots

[0050] The Schisandra chinensis plants with good growth are used to cultivate strong sprouting branches at the base of the mother tree to ensure the vigorous growth of the sprouting branches. Prepare the layering propagation operation 3 months before the mother tree leaves.

[0051] 2. Sprout branch layering

[0052] Dig a ditch with a depth of 12cm from the surrounding land below the sprouted tiller branches cultivated. The length of the ditch depends on the length of the sprouted tiller branches. The sprouted tiller branches are pressed in the ditch, filled up with fine soil, and the front ends of new shoots are exposed to the ground. . 35 days before plant defoliation, pinch the heart to control growth. After the plant enters the dormant period, cut off the shoots from the base and separate from the mother tree.

[0053] 3. Single bud propagation

[0054] After the soil thaws in spring, dig out the rooted layering strips, cut them into ...

Abstract

The invention discloses a Chinese magnoliavine layering propagation method, and belongs to the technical field of plant cultivation. The method comprises following processing steps: 1) digging trenches on the land around descendants of a Chinese magnoliavine seed tree; layering the descendants serving as layered branched in the trenches; filling and leveling up the trenches; enabling front segments of new shoots to be exposed on the land; pinching the descendants; and separating the descendants from the seed tree at the base after the plant goes into a dormancy stage; and 2) digging out the rooted layered branches; cutting the rooted layered branches into single bud branches provided with roots; cultivating each single bud branch with the eye being upward; covering buds with soil; applying a soil bactericide for one time; shading the buds; and removing the shading after seedlings survive. By employing the method, the operation is easy, the seedling growing speed is fast, the survival rate of the seedlings is high, and the management is facilitated. The method is a Chinese magnoliavine vegetative propagation cultivating method having relatively high promotional values.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a layering propagation method of Schisandra chinensis. Background technique [0002] Schisandra is a magnolia plant, a perennial deciduous woody vine, and is a large and authentic Chinese medicinal material mainly produced in Northeast my country. In recent years, the destruction of wild resources of Schisandra chinensis has become more and more serious, while its market demand is increasing day by day, which makes the artificial cultivation of Schisandra chinensis develop rapidly. [0003] At present, the artificial cultivation of Schisandra chinensis mainly adopts seedlings to build orchards. Due to the large variation among different individuals, the plants propagated by seeds have shortcomings such as uneven quality, uneven maturity, uneven resistance, and poor high and stable yields. [0004] In view of the many deficiencies in the seed reproduction of Schisandra ...
