The culture method of big flower six trees how to cultivate big flowers six trees

The way of planting big flower six trees with ground load is more suitable, in the engineering application, it is necessary to plant large flowers six trees reasonably in order to avoid the excessive growth and deformation of large flowers.

First, the introduction of Dahua Liudaomu

Shape: evergreen shrub, about 2 meters high. Branchlets slender, sunny purplish red, arched. Leaves small, long ovate to long oval-lanceolate, margin with sparse shallow teeth, bright green on the front and light green on the back. Paniculate Cymes, small flowers, white with powder, luxuriant and fragrant. The florescence lasts from June to October and sometimes lasts until the middle of November.

Ecological habits: originated in Europe. Like light, heat-resistant and cold-resistant. It has strong adaptability to soil, grows well in acidic, neutral or alkaline soil, and has a certain ability to tolerate drought and barren. Strong branching force, resistant to pruning.

Garden use: the flower color of Liudao wood is pink and white and various, which is lovely. After the flower fades, the pink sepals persist until winter, which is very beautiful. The flowering period is as long as half a year, and it is an excellent summer and autumn flower and foliage shrub.

Variety: its variety has six trees with golden leaves and flowers, which is an evergreen dwarf shrub. The leaves have a gilt edge and a bright color.

II. Matters needing attention in the planting of Artemisia mandshurica

Matrix preparation: the matrix is mainly perlite and yellow sand with strong air permeability and good filterability. in order to closely combine the root system with the substrate after rooting and improve the survival rate of changing pots, a certain proportion of peat and plant ash can be added to the matrix. the mixed seedling substrate material was loaded into a 128-hole hole to be inserted.

Cuttings collection and treatment: big flowers and six trees can be planted and cultured all the year round, mature branches can be used in winter or early spring, and they can blossom in the same year; in spring, summer and autumn, they can be cut with semi-mature branches or twigs, and the cuttings can be treated with rooting powder and inserted into a burrow plate. Using this method to root quickly, generally 3-5 days began to form the root system, the root system is developed and the rooting survival rate is more than 98%.

Seedbed management: the water content of the substrate is kept at 70-80% before the cuttings are rooting, and the leaf surface is moisturized just before the root system is formed. After rooting, the moisture content of the substrate was reduced to 60%, which reduced the number of sprays and promoted root growth. After insertion, methyl topiramate (or carbendazim) can be sprayed once a week; in order to promote root growth, 0.2-0.3% urea and potassium dihydrogen phosphate can be used for foliar topdressing, usually once a week, and can be mixed with fungicides.

Third, the methods to prevent the overgrowth of Dahuadao trees.

In engineering application, reasonable close planting, careful management and protection, and ensuring the survival rate are the key to avoid disorderly growth. When six trees with large flowers are used as hedges, they must be pruned properly to prevent overgrowth.

There are three main reasons for the growth of big flowers: the reason of the variety itself; during the shaping of young trees, the big branches are left too little, or clustered, the lateral branches are too few, and the nutrients are too concentrated; or the strong branches are cut too heavily, and the branchlets are cut too much; improper fertilization during the cultivation period. During the period of young trees, nitrogen fertilizer, chemical fertilizer or large amount of fertilizer and water are applied, and less organic fertilizer is applied, resulting in excessive growth of branches.

The following measures can be taken to prevent the overgrowth of large flowers: when transplanting, truncate part of the main root and overlong roots to promote the growth of lateral roots; appropriate close planting; in pruning and shaping, the overgrowth of seedlings can be controlled by cutting off overlong main branches, leaving more branches and more lateral branches as flowering branches. The overgrowth of new shoots can be inhibited by spraying B-9, paclobutrazol, dwarf and other growth regulators. In terms of fertilization, it is necessary to increase the application of phosphorus and potassium fertilizer, after the new shoots grow to a certain length, we should pay attention to the control of fertilizer and water. Rain Water does a good job of drainage in many seasons.

Because it can be planted and survived all the year round, it is also a kind of shrub that is easy to raise. If you have friends in the courtyard, you should be quite satisfied with choosing the tree to decorate the courtyard.
