Description
Technical Field
The invention relates to a propagation method of ornamental flowers, in particular to a propagation method of agapanthus bud promoting and division.
Background
Agapanthus spp, also known as lilium brownii, african love flower, perennial evergreen or deciduous herbs. The generic name of Agapanthus comes from Greece, agape means "love", antros means "flower", Agapanthus means "love flower", and flower means "romantic love" or "love coming". The Cape Kapu province originally produced in south Africa of Baizilian is introduced into England along the coast of India ocean to Limpopo forest wave river basin of North, from above sea level to the height of 2100m, and in the middle of seventeen century, through the development of more than three hundred years, bulbous flowers which are indispensable in summer now are used for decorating European courtyards, and are love flowers which express love second only in China. The agapanthus has strip-shaped leaves and terminal cymbidium floribundum inflorescence, and plants formed by the leaves and the inflorescences have elegant appearance, blue-white-purple flower color, 6-9 months of flowering period, large and bright flower, long flowering period, strong adaptability and less plant diseases and insect pests, not only can be used as fresh cut flowers, but also can be used for cultivating pot flowers, flower beds or plants in flower beds, and have wide application range, can fill up the defects of cool-tone flower varieties in summer, and highlight out-of-range amorous features.
The first African agapanthus introduced from south Africa in China is basically introduced seeds, character separation is generated after the seeds are propagated through sexual generations, mixed colors appear in offspring groups, and the ornamental quality is greatly influenced. Because the agapanthus praecox grows 1-2 new buds on two sides of the scape after blooming in a natural state, and only new leaves and few new buds grow on a root-stem disc when the plant does not bloom, the propagation coefficient is low by depending on the traditional plant division propagation mode. However, the agapanthus is propagated by adopting a vegetative organ explant to perform tissue culture, although a large amount of agapanthus seedlings can be obtained in a short period, the progeny can have a phenomenon of flower reduction.

Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and drawings.
Example 1:
the agapanthus is a perennial herb of rhizomes, and the evergreen agapanthus is generally evergreen in leaf color above 0 ℃ in winter. Selecting single-stem agapanthus, vertically downwards cutting to the root and stem disc position along the middle part of two rows of leaf clusters of agapanthus by a sharp cutter at the bottom of 11 months in the first year, forcibly downwards incising to reach 2cm, and cutting off the upper leaves to only leave the base part of the leaf cluster. Moist peat is spread around the roots and stems to keep moist. Before low temperature cold tide in winter, the plastic film is covered for heat preservation, the plastic film is removed when the air temperature is warmed up (more than 10 ℃) in spring of the next year, and when the soil is dry, water is properly watered to supplement water. When the temperature reaches 15 ℃, the basal part of the agapanthus praecox starts to sprout 6 new buds along the lower rhizome part of the growing axis of the leaf cluster, the induced lateral buds are divided into plants in the second year in the middle 9 th month, the single buds are cut and partial rhizome blocks and fibrous roots are transplanted into a cultivation medium (the volume ratio of turf: perlite =3: 1), then 6 single plants are generated by dividing one plant, and the propagation coefficient is 6.0, as shown in figure 1.
The bud promotion induction can be carried out again by following the method, and the annual propagation coefficient of the agapanthus reaches 6.0 in the circulation.
The top bud of the agapanthus is thoroughly blocked from growing in the incised wound mode, the side buds of the root and stem disc are promoted to grow to generate more new buds, and the new buds are propagated into single seedlings through sub-plants, so that the regular and consistent commodity seedlings are produced. Compared with the traditional natural plant division propagation efficiency, the method greatly improves the propagation efficiency, and has important significance for the expanded asexual propagation of newly introduced or newly bred agapanthus varieties with excellent characteristics.
Example 2:
the agapanthus is a perennial herb of rhizomes, and the evergreen agapanthus is generally evergreen in leaf color above 0 ℃ in winter. Selecting single-stem agapanthus, inserting into the center of the root-stem disc with a sharp screwdriver at the bottom of 11 months in the first year until the penetration depth reaches 2cm, and rotating left and right to kill central bud injury and completely block the growth of the central bud. Then, the leaves of the overground part are cut off, only the base of the leaf cluster is left, and the moist turf is paved along the periphery of the rhizome, so that the wound is buried. Moist peat is spread around the roots and stems to keep moist. The plastic film is covered before the winter low-temperature cold tide is preserved, the plastic film is removed after the temperature is warmed up again (above 10 ℃) in spring in the next year, when the soil is partially dry, water is properly watered to supplement water, when the temperature reaches 15 ℃, the lotus root base starts to sprout 8 new buds along the lower rhizome part of the growing axis of the leaf cluster, the lateral buds are divided into plants in the middle ten days of 9 months in the second year, the divided buds are cut, partial root blocks and fibrous roots are transplanted into a cultivation medium (the volume ratio of turf: perlite =3: 1), then 8 individual plants are generated by dividing one plant, the propagation coefficient is 8.0, and the method can be seen in figure 2.
The bud promotion induction can be carried out again by following the method, and the annual propagation coefficient of the agapanthus reaches 6.0 in the circulation.
The above description is only intended to represent the embodiments of the present invention, and the description is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
