Rapid propagation method for twig of fraxinus chinensis

A technology of ash flower and twigs, applied in vegetative propagation, botany equipment and methods, planting substrates, etc., can solve the problems of restricting large-scale development, slow growth of cutting root system, and prone to death after transplanting, so as to promote the growth of root system. The germination and seedling raising cycle is short, and it is convenient to raise a large number of seedlings

Problems solved by technology

[0004] Through the above analysis, the problems and defects of the prior art are: the prior art mainly adopts the lignified branch cutting propagation seedling method, which requires many branch materials, slow propagation speed, difficult rooting, slow growth of the cutting root system in the early stage, and transplanting. Prone to mortalities, limiting its large-scale development

Embodiment 1

[0072] Different heights of embodiment 1 truncate the effect contrast of promoting germination

[0073] In June and September 2017, the experiment was carried out twice at the Haikou base of the Institute of Tropical Horticulture, Hainan Academy of Agricultural Sciences. The test materials were selected from the mother tree of the variety of ash, which had been planted in full sun for 2 years, with a height of 1.2-1.5m and a crown width of 80-100cm. Cut off the top of the main trunk of the pink ash flower mother tree that is planned to be used as cuttings at a height of 30, 40, 50, 60, and 70 cm from the ground and process it, and simultaneously remove the branches on the trunk at 5 cm from the main trunk, totaling 10 20 plants were treated for each height, and the control group was treated without pruning. Dig a shallow ditch with a small hoe at the base of the stem 30cm away from each plant, with a depth of 8-10cm, bury 100-150g of ternary compound fertilizer for each plant...

Embodiment 2

[0078] Embodiment 2 twig rapid propagation experiment

[0079] In April 2018, this embodiment 2 was implemented at the Haikou base of the Institute of Tropical Horticulture, Hainan Academy of Agricultural Sciences, and was carried out 1 time at intervals of 10 days, a total of 3 times. Utilize the twigs intercepted on the 50cm height from the ground in September in embodiment 1 to cut off the top treated Fructus chinensis mother tree to carry out rapid propagation.

[0080] 1. The specific steps for the substrate preparation of the cutting seedbed are as follows: build the cutting seedbed in the sunshade shed at the base according to the specifications of 300cm long * 120cm wide * 24cm high, and surround the seedbed with light cement foam bricks; use coconut peat and perlite , river sand, and laterite are mixed according to the volume ratio of 3:1:2:5, and then 50 times dilution of 40% formaldehyde is used to spray the substrate with a dosage of 20L / m3, and cover and seal with...

Embodiment 3

[0086] Embodiment 3 twig rapid propagation experiment

[0087] Gather again in June the twig that same batch of white wax mother tree germinates again as cuttings, repeat the process of embodiment 2.

Abstract

The invention belongs to the technical field of horticultural seedling propagation, and discloses a rapid propagation method for a twig of fraxinus spectabilis, top cutting and germination promotion on the fraxinus spectabilis planned as a cuttage seed tree are carried out for first two months, and strengthened management on the seed tree is carryed out; a substrate of a cuttage seedbed is prepared, the twig and a cuttage slip are collected, and a composite rooting bactericidal agent is processed; a cuttage is carried out on the cuttage seedbed according to a certain plant row spacing specification, a thorough watering is immediately carried out once after the cuttage, so that the cuttage slip is tightly combined with a cuttage medium; management after the cottage is carried out, and a seedling is transplanted into a nutrition cup after 7 days of seedling hardening; the seedling is transplanted out of a seedling nursery and the seedling hardening management is carried out; 10 days before planting in a field, a sunshade shade net is uncovered, all-light irradiation is adopted for the seedling in the nutrition cup, potassium chloride is sprayed to leaf surfaces, watering is gradually stopped, and the resistance of the seedling is improved. According to the rapid propagation method for twig of fraxinus chinensis, a large number of excellent cutting seedlings can be obtained, scale production is promoted, and a foundation is laid for promoting industrial development of new woody cut flower varieties.

Description

technical field [0001] The invention belongs to the technical field of horticultural seedling propagation, and in particular relates to a method for rapidly propagating twigs of Fructus chinensis. Background technique [0002] At present, Chamelaucium uncinatum "Stirling Wax", a perennial evergreen plant of the family Myrtleaceae, is resistant to drought, barrenness and strong adaptability. It grows best at 15°C to 35°C The area in the same period grows the most vigorously and does not have high requirements on the soil. It is an ideal material for flower arrangement. It has gradually become a new type of high-grade pink woody cut flower that is popular in the world and is very popular in the international market. [0003] As a new type of woody cut flower variety, the small-scale commercial production and development of A. chinensis has begun in the south of my country, but because of its small seeds, it is easy to fall off, it is difficult to collect, the variation rate of...
