Question 3: What is Euonymus japonicus? Buxus macrophylla
(Euonymus japonicus)
Buxus macrophylla, also known as Zhengmu, belongs to Euonymaceae.
[Morphological characteristics]
Buxus macrophylla is an evergreen shrub or small tree with slightly quadrangular branchlets, dense branches and spherical crowns. The single leaf is opposite, obovate or elliptic, with blunt teeth at the edge and dark green luster on the surface. Cymes are axillary, with long stems and green and white flowers. Capsule spherical, reddish, aril orange. (See Figure 3)
Common varieties are: Buxus macrophylla with golden leaves in Phnom Penh; Euonymus japonicus leaves have golden spots in the center, which are all important foliage trees.
[Habitual]
Buxus macrophylla is a temperate and subtropical tree species, which is produced in the north-central provinces of China and widely cultivated, and also distributed in Japan. Like light, but also more resistant to yin. I like warm and humid climate, and I am more tolerant of' cold'. It needs fertile and loose soil and is very resistant to pruning and shaping.
[Cultivation techniques]
Propagation: Cutting is the main method, and sowing can also be used for propagation.
Cutting can be carried out in spring and summer, and semi-mature shoots grow faster and grow better in June. In the early stage after transplanting, a shed should be set up for shade to keep the seedbed moist. The growth rate of cutting seedlings is much faster than that of sowing seedlings. Buxus macrophylla is usually cultivated into a spherical crown and replanted.
Management: Seedling transplanting is mostly carried out in March-April in spring, and large seedlings need to be transplanted with soil. The main management work is pruning and shaping. Its branches are easy to sprout after pruning, so it needs pruning several times a year to keep a certain tree shape.
The pests of Buxus macrophylla include scale insects, flat moths, Buxus macrophylla, etc., which harm the leaves and should be controlled. 20 times of turpentine mixture can control scale insects; Use 40% omethoate or 1000 times isocarbophos to control moths and boxwood in larval stage.
[use]
Buxus macrophylla leaves are bright and light green, which is extremely resistant to pruning. It is a common hedge tree species in the courtyard. It can be planted by shaping the roadside around the door or as the center of the flower bed. Its variegated leaves are particularly beautiful. Houses can be decorated with green doors and green walls, or potted for viewing.
Question 4: Does Euonymus japonicus belong to trees or shrubs? Buxus macrophylla is an evergreen shrub or small tree, which can be as high as 5 meters.
Question 5: Euonymus japonicus, what is this disease? Powdery mildew of Euonymus japonicus.
Preventive and control measures:
1. Improve the cultivation conditions, and the planting site should be high, dry, sunny, without stagnant water and deep and fertile soil.
2. Strengthen the management of fertilizer and water, increase the application of phosphorus, potassium fertilizer and appropriate amount of nitrogen fertilizer; Pay attention to drought resistance and drainage to make seedlings grow healthily and improve disease resistance.
3. Combined with pruning, cut off diseased branches and leaves. Do a good job in clearing the garden in winter, sweep away diseased branches and leaves, and burn them centrally; When the diseased leaves are found in the growing period, cutting off the diseased branches and burning them in time can effectively reduce the primary infection source and reinfection of the disease.
4. Use chemicals reasonably and prevent them in time, and pay attention to the alternate use of chemicals to avoid drug resistance of powdery mildew; Spray the medicine carefully and pay attention to the inner chamber and the back of the leaves. Use 3-degree stone sulfur mixture for prevention and treatment twice in winter, with an interval of 1 month. The following chemicals can be used to control Euonymus japonicus during leaf spreading and growth period, especially in April-May and 9- 10. 25% triadimefon 800- 1000 times, 70% thiophanate-methyl 800 times, 50% diphenhydramine 1000- 1500 times, 50% triadimefon 800 times, 40% thiram 600 times, 0.

The seed is brown and the aril is orange-red. The flowering period is from June to July, and the fruit ripens in 9-65438+1October. Widely cultivated in all provinces for viewing; This species is very resistant to pruning and is a good fence material. The experiment of Jiangsu Institute of Botany shows that this species has strong resistance to sulfur dioxide. Propagation by cutting or cutting.
