Problems solved by technology

[0003] (1) The existing cutting technology is mainly to cut the treated cuttings in different substrates. The process of cuttings callus and rooting are all in the substrates, but the water content of the cutting substrates is difficult to maintain at a constant level suitable for cuttings rooting. Low water content will easily lead to dehydration and wilting of cuttings, and high water content will result in poor air permeability, easy to breed various germs and rot
(2) The existing technology mainly uses fungicides or high-temperature treatment to sterilize the matrix to reduce the rot rate of cuttings. Although it can produce certain effects, there are obvious deficiencies
The use of fungicides to disinfect substrates is affected by factors such as watering, and there are disadvantages such as short duration, difficult dosage, incomplete sterilization, etc., and the dosage is large and the cost is high; high-temperature disinfection is prone to secondary infection of germs and is not suitable for large-scale Production
Especially for cuttings in summer, affected by high temperature and high humidity, various pathogenic bacteria in the substrate multiply rapidly and have strong infectivity, which can easily cause cuttings to rot, which greatly affects the survival rate of cuttings
[0004] Lilac cuttings have the characteristics of difficult and slow rooting, and the rooting rate of existing cutting methods is low, less than 40%.

Embodiment 1

[0035] Embodiment 1 A kind of rooting cutting seedling raising method of lilac matrix, taking lilac 'Julie' as an example, comprises the following steps:

[0036] (1) Preparation of cutting facilities

[0037] The cuttings are made of plastic sheds, and the shed film is covered with a sunshade net with a shading rate of 70%. An automatic fogging system is installed in the shed, and the fog droplets are less than 5 μm. The cutting matrix is ​​made of perlite and peat, mixed at a volume ratio of 1:3. , sterilized with 30% hymexazol water solution 1500 times, then packed into nutrient bowls of 10cm×15cm, and placed them in the shed closely, with the sides 60cm away from the shed wall and 120cm apart, leaving a 50cm channel in the middle for easy management. Before inserting, use 50% carbendazim wettable powder 800 times liquid to disinfect the inner wall of the shed and the exposed area on the ground.

Embodiment 2

[0057] A method for raising seedlings by rooting and cuttings of Eurygmus officinalis, which is illustrated by taking Eurygium syringa 'Shaxuan' as an example, comprising the following steps:

[0058] (1) Preparation of cutting facilities

[0059] Cuttings are made of plastic sheds, covered with a sunshade net with a shading rate of 70% outside the shed, and an automatic fogging system is installed inside the shed. After disinfection, the 1500-fold solution of Mycosin water agent is divided into nutrient bowls of 10cm×15cm, and placed in the shed close to each other. The two sides are 55cm away from the shed wall, and the distance is 120cm, leaving a 50cm channel in the middle for easy management. Use 50% before inserting. Carbendazim wettable powder 800 times liquid is used to disinfect the inner wall of the shed and the exposed area on the ground.

Embodiment 3

[0078] A method for raising seedlings by rooting and cuttings of Eurygmus officinalis, which is illustrated by taking Eurygium syringa 'Shaxuan' as an example, comprising the following steps:

[0079] (1) Preparation of cutting facilities

[0080] Cuttings are made of plastic sheds, covered with a sunshade net with a shading rate of 70% outside the shed, and an automatic fogging system is installed inside the shed. After disinfection, the 1500-fold solution of Myco-Aqueous Liquid is divided into nutrient bowls of 10cm×15cm, and placed in the shed close to each other, with 50cm away from the shed wall on both sides and 120cm apart, leaving a 50cm channel in the middle for easy management. Use 50% before inserting Carbendazim wettable powder 800 times liquid is used to disinfect the inner wall of the shed and the exposed area on the ground.

Abstract

The invention discloses a cuttage seedling method for rooting syringa vulgaris L. outside matrices. The method comprises the following steps: preparation of a cuttage facility, scissoring of cuttings, sterilization, girdling and rooting treatment, cuttage and management after cuttage. The cuttage seedling method has the beneficial effects that healing and root primordia differentiation of the cuttings are effectively promoted, so that the rooting rate, survival rate and maternal plant seed and joint utilization rate of cuttage seedling can be obviously increased; compared with conventional cuttage, the cuttage seedling method has the advantage that the cuttings can root 3-7 days ahead; the probability that the cuttings are infected with diseases and pests can be reduced, thus effectively avoiding rot of the cuttings; the cost is saved; the requirements of the cuttings for the environments of the matrices are reduced, thus reducing the selection and treatment standards of the matrices and expanding the selection range; the cuttage seedling method is suitable for intelligent and standard production and has the advantages of simplicity in operation, labor saving, high economic benefits, and the like.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings by cuttings with external roots in a lilac substrate, and belongs to the technical field of plant propagation. Background technique [0002] Lilac ( Syringa vulgaris L. ), native to Europe, Oleaceae Syringa, shrubs or small trees; cold and drought resistant, more resistant to barrenness, strong resistance to diseases and insect pests, large amount of flowers, rich colors, and unique fragrance. It is an ornamental value introduced in my country in recent years. One of the tallest tree species; its economic benefits are high, and the future market demand will be huge. The main cultivars introduced at present are 'Holden' ( Syringa vulgaris 'Albert F. Holden'), 'McCann' ( Syringa vulgaris 'Arch McKean') 'Mosca' ( Syringa vulgaris ‘Krasavitsa Moskvy’), ‘Julie’ ( Syringa vulgaris 'Charles Joly'), 'Marianne' ( Syringa vulgaris 'Marie...
