Gardenia multi-branch floating bed water planting cuttage method

Abstract

The invention discloses a gardenia multi-branch floating bed water planting cuttage method. The gardenia multi-branch floating bed water planting cuttage method is characterized by comprising the following steps that a large branch with 3-5 shoots is selected, the diameter of the root of the branch is larger than 0.5cm, terminal buds grow on the two sections of the shoots, and 3-5 leaves are left for each shoot; the root part, with the length ranging from 2cm to 5cm, of the branch is immersed into the mixed solution of alpha-naphthylacetic acid and indolebutyric acid to be dipped for 2-3 seconds; a sunshade net shed with the 50% sunshade ratio is established on the outdoor cleaning water surface, and cutting slips are inserted into plastic foam which serves as a cuttage support to be cultured and protected. The gardenia multi-branch floating bed water planting cuttage method has the advantages that the water surface floating bed cuttage is adopted, the oxygen in the water is sufficient, the forming of the callus is facilitated, the water temperature is stable, the temperature difference between day and night is small, the air humidity on the water surface is high, the branch absorbs water easily, the leaves cannot wither and fall even when encountering water loss and can carry out the photosynthesis to synthesize nutrient substances, the root system is well developed, the ability of absorbing nutrients is strong, the survival rate in the process of cultivation is high, and the growing speed is high; frequent spraying and water changing are omitted, managing links such as intertillage and weeding in a nursery garden land and workloads are removed, the gardenia multi-branch floating bed water planting cuttage method is simple and easy to implement, and mass propagation can be achieved.

Description

technical field [0001] The invention relates to a cutting method, in particular to a hydroponic cutting method of gardenia multi-branched floating bed, and belongs to the technical field of plant cultivation. Background technique [0002] Gardenia jasminoides Ellis is an evergreen dwarf shrub belonging to Rubiaceae Gardenia. Gardenia leaves are emerald green and bright, flowers are large and white, and have a pleasant fragrance. It is one of the top ten fragrant flowers and is widely used in landscaping. It is also an important potted flower and cut flower. At the same time, Gardenia is also an important Chinese herbal medicine. Gardenia yellow pigment is a mixed pigment widely used in the dye industry, food processing industry and beverage manufacturing industry. [0003] Gardenia often adopts cutting propagation, branch propagation, layering propagation and seed propagation. The propagation coefficient of the ramet and layering propagation methods is low, and the seed pr...

Problems solved by technology

Cutting propagation can maintain the excellent characteristics of the female parent and has a large reproduction coefficient. It is the most commonly used method for gardenia propagation at present, but the field management of cutting propagation is cumbersome; Water, spray water, etc.; traditional soil culture and hydroponics have a long cycle and slow seedling growth; it has been reported that using cuttings of gardenia hard branches and large branches in paddy fields can greatly shorten the time for cultivating large gardenia seedlings, but it is inconvenient to take seedlings and will Affects rice harvest and has not been used in large-scale production
