Chinese mugwort cutting propagation method

Abstract

The invention belongs to the technical field of plant vegetative propagation and discloses a Chinese mugwort cutting propagation method. The method includes the following steps that: a Chinese mugwortgrowth-phase shoot is scissored, a stem with axillary buds is obtained, the stem is soaked with tap water and then is soaked with a composite rooting agent; an obtained shoot is inserted into a loosehumus soil matrix and is covered with straw, with the soil kept moist; an arc shed is erected, is covered with a shading net, and is further covered with a plastic film, and air humidity inside the shed is controlled; the shoot is sprayed with a bactericide regularly, so that the growth of bacteria can be prevented; and after the cottage of the shoot, adventitious roots send forth. The shoot of astrain of high-quality Chinese mugwort is collected, and undergoes cutting propagation so as to grow into a seedling; the genotype of the seedling are identical to that of the stock plant, and a clone with excellent cultivated characters can be planted; and yield increase and high quality characteristics can be given to full play; and genetic differentiation can be avoided. With the Chinese mugwort cutting propagation method of the invention adopted, a large number of plants with the same genotype can be propagated through cottage, namely a stock plant can be cloned, and economic benefits canbe maximized.

Description

technical field [0001] The invention belongs to the technical field of plant asexual propagation, and in particular relates to a cutting propagation method of mugwort. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Wormwood, perennial herb or slightly semi-shrub, the plant has a strong aroma. Stems solitary or few, brown or grayish-brown, slightly lignified at the base, fleshy at the upper part, with a few short branches, thick papery leaves, gray-white pubescent above, usually without false stipules or very small at the base False stipules; upper leaves and bracts pinnately half-cleft, flower head elliptic, corolla tubular or goblet-shaped, with glandular points outside, anthers narrowly linear, style and corolla nearly as long or slightly longer than corolla. Achene oblong or oblong. The flowering and fruiting period is September-October. The whole herb is used as medicine, which has the effect...

Problems solved by technology

[0006] At present, the method of subterranean stem division is mainly used in production to propagate seedlings. Each mugwort can reproduce 3-5 plants, and the seedling reproduction rate is low.

Sowing and reproduction requires a large amount of high-quality seeds, which are difficult to collect. In many places, there are no mature seeds due to insufficient frost-free period
