#Chinese Authentic Customs# Passing by the flower bed every day, Qingjiang Crane is always "familiar with the bright and eye-catching shrubs" on the flower bed.
Until one day, when a friend who was traveling with him asked Qingjiang Crane what the name of this bush was, he actually made Qingjiang Crane think for a long time, and did not call out the name of this bush.

Golden-leaved shrub is a deciduous shrub in the genus Verbenaceae. Because its leaves are all golden yellow, it can be "yellow" from the budding of leaves in early spring to fall off from the main branch, basically throughout its growth cycle. During this period, two more flowering periods bloomed to meet the needs of consumers to "watch the leaves and enjoy the flowers".
Therefore, in many township street green plantlands, rural leisure tourism scenes, urban parks, green public land and other places can see the shadow of this golden-leaf tree, or solitary plants or clusters, or embellished or made into color bands (hedges), and red-leaved barberry (red), pine juniper (green), small-leaved boxwood (autumn yellow) and so on to form a "color difference" to beautify the environment. It's just that you don't pay attention or "turn a blind eye" and forget like a Qingjiang crane.

A cluster of yellow in spring and summer, and blue in autumn. It is the "finishing touch" of the "garden" group greening decoration:
The important reason why Golden Leaf is widely used in garden landscaping is its distinctive color in the "whole growth period" and the unique "blue" beauty of autumn. In the decoration of land for landscaping, there is its appreciation value of "color" and "flower view".
The height of the golden-leaf plant is 70cm~80cm (the height of the plant can be artificially controlled), the branches are garden-shaped, the leaves are ovate, about 3~6cm long, the base of the leaf is end-garden-shaped and the tip is gradually pointed, the leaves are toothless, goose yellow.
Bell flowers are blue or purple and bloom for about 2 months. It grows on slopes, woodlands or corners with sunny and fertile soil, deep and draining soil.
In fact, this goldenrod is very resistant to barrenness, and it grows very luxuriant in many piles of rocks and shallow soil. And it is very hardy, drought and heat resistant. No matter how high the temperature is, I have not seen "burns" of gold leaf beetle, no matter how big the cold wave is, I have not seen gold leaf beetle "frozen and broken skin", no matter how strong the dry and hot weather, I have never seen gold leaf leaf beetle "dead branches topped". Therefore, it is a very good choice to use gold leaf as a wall in the courtyard, or a hedge in the neighborhood, and the "hedge" of the green plant.

Propagation by cuttings is the most important way for the rapid propagation of goldenrod:
Golden-leaf butterfly is very "cheap", and it is very easy to survive by propagating from cuttings.
Qingjiang He, a friend who specializes in green plant decoration, has to engage in a large number of golden leaf cuttings every year. The method is the same as the cuttings propagation method for other seedlings.
The propagation time of cuttings is mainly in spring. As long as the seedbed is done, the one-year or two-year-old semi-lignified shoots, cut into 15~20cm cuttings (at least 2 shoots are required), and treat the cuttings with rooting powder or rooting agent solution (such as 1.8% Guoguang rooting agent 8~10g with water 30~45 city jin) (the cuttings should be cut into horse ears to facilitate cuttings to take root), and then insert them on the cultivation bed. Two-thirds of the earth, leaving one-third on the bed.
After the cuttings are completed, they should be covered with fine soil sifted, and then sprayed with water to bond the fine soil with the cuttings, and then covered with plastic film to keep warm and moisturizing. The film should be covered with 2 layers, and one inner film and one small arch. After the cuttings germinate, the inner membrane is withdrawn early to prevent "burning the seedlings".

One-year cuttings can basically emerge in autumn and winter, although the quality of biennial seedlings is better. Because 2-year-old seedlings need to be pruned in the spring and summer of the second year, which can promote the multi-branching and reproductive growth of seedlings, and flowers can be bloomed in autumn.
The effect of goldenrod in the garden landscape landscaping as a "hedge" cultivation sheet is excellent:
Because the leaves and blue flowers of the golden leaf are very beautiful and distinctive, they are often cultivated as "hedges" in many urban gardens, public green fields, rural revitalization green belts and other landscape green areas. With the red leaf barberry, the monthly set is planted into various patterns of color blocks, and the golden leaf is often the "finishing touch" in the greening effect.
The planting density is much denser than that of solitary plants. In the spring and summer of the following year, the patches of goldenrod are pruned, either in strips or into balls. It can also be cut into a "flat-headed" square and other appearance, how to look good and how to cut, there is no fixed "iron rule".

The "fast-growing" nature of the goldenrod is very strong, and the weeds between the plants basically cannot interfere with its growth. So the grass damage is still relatively light. Weed hazards are mainly in the "gap" ground, closed herbicides can be used to carry out closed weeding of the soil, such as 90% acetochlor emulsion 40 ml ~ 60 ml / bucket of water can be closed treatment of the soil.
Secondly, goldenrod is very resistant to barrenness, and the demand for fertilizer is not very high. In the cultivation period of young trees in kindergartens, only 1~2 times of fertilization are required to form the plant.
Comprehensive pest control measures during the cultivation of Golden leaf leaf beetle:
During the planting process, there are often suction mouthparts pests such as aphids, insects, and shells, and diseases and pests such as leaf spot and blight that harm leaf branches.
In production, 10g of 10% imidacloprid wettable powder can be combined with 40% chlorpyrifoli emulsion 20ml/bucket of water, or 10% pyrafenone water dispersible granules 10g/bucket of water and 70% methylthiophanate wettable powder 800~1200 times liquid, and 70% manganese zinc wettable powder 500~800 times liquid, the prevention and treatment of diseases and pests of Chrysophyllum chinensis is very good.
Conclusion: This paper mainly shares the biological characteristics of Chrysophyllum chinensis, the basic methods of cuttings propagation, and the comprehensive prevention and control of diseases and pests in the planting process. It is the sharing of technical data for efficient planting of goldenrod, which can be used as a technical reference and reference in the process of cultivation of goldenrod.
