Clivia pseudo-bulb cuttage propagation method

Abstract

The invention relates to a clivia pseudo-bulb cuttage propagation method and belongs to the fields of plant cultivation technology, landscape plant and ornamental horticulture. The method comprises mixing turfy soil, perlite and leaf mould at a certain proportion into the culture medium for cuttage propagation of clivia pseudo-bulb; putting the culture medium into a seedling raising plate through appropriate pH value adjustment; cutting clivia pseudo-bulb slices into the culture medium after sterilization and rooting, and providing an appropriate temperature and humidity environment for the clivia pseudo-bulb slices; after the cut clivia pseudo-bulb slices sprout roots, transplanting and culturing the clivia pseudo-bulb slices under greenhouse conditions through regular management methods into normal clivia plants. According to the clivia pseudo-bulb cuttage propagation method, by means of cuttage propagation, the sliced clivia pseudo-bulb can be in an excellent growth environment, thereby effectively improving the growth by differentiation and the propagation rate.

Description

technical field [0001] The invention relates to a method for cutting and propagating Clivia pseudobulbs. The invention belongs to the fields of plant cultivation technology, garden plants and ornamental gardening. Background technique [0002] Clivia miniata is a perennial herbaceous plant of the genus Clivia in the family Amaryllidaceae. It is native to southern Africa and grows under trees. Therefore, it is afraid of heat and cold. It likes a semi-shady and humid environment and is afraid of strong direct sunlight. , the optimal temperature for growth is between 18-22°C, below 5°C, and above 30°C, the growth is inhibited. At present, five species of Clivia have been found, which are called Nobilis, miniata, Garden Clivia (gardenii), Stem Clivia (caulescens) and Mirabilis Clivia (mirabibis). Clivia was introduced to my country from Europe and Japan successively in this century. At present, Clivia grandiflora is mainly planted in my country. Clivia likes a ventilated envi...

Problems solved by technology

At present, the breeding method of Clivia is mainly based on seed planting and division propagation. Since the genotypes in the genetic structure of Clivia are mostly heterozygous, the seed planting method is not necessarily able to reproduce even if the seeds are obtained due to its genetic instability. Phenotyped plants, the probability is very low; in addition, division propagation requires adult Clivia plants to grow sub-buds and then divide the plants, and at most 1-3 plants will be separated in a year; in recent years, some laboratories have successfully carried out Clivia. For tissue culture experiments, there are still some disadvantages of instability and high cost in experimental operations
