How to raise single trees? methods and matters needing attention in single tree culture

Single tree is regarded as a kind of tree introduced and cultivated from abroad, and it can be seen in many parts of our country at present. Single tree attracts a lot of people because of its high ornamental value. However, before breeding, we must still need to have a comprehensive understanding of its breeding technology, so as to ensure its growth.

How to raise a bachelor tree

1. Suitable temperature: single trees like to be warm and resistant to drought, salt and wind, and like light. The general growth temperature is about 25-30 ℃.

2. Suitable soil: the soil with good drainage is more suitable, because the single tree itself is resistant to drought.

3. Suitable humidity: single trees are resistant to drought, salt and wind, and the humidity is not easy to be too high, so it is better to be dry.

4. Suitable lighting: bachelors have good light and should be placed in the open air, but avoid exposure to the sun.

Culture methods and matters needing attention of single trees

1. Culture methods:

1. Soil: when planting single trees, you should choose soil with strong drainage performance. you can choose rotten leaf soil and garden soil according to the proportion of 2:1, while adding a small amount of river sand to form culture soil, and you can put less long-acting fertilizers such as hoof slices at the bottom. in order to enhance drainage performance, you can also pad a layer of gravel and tiles in the basin.

2. Lighting: as mentioned earlier in the introduction of growth habits, a single tree is a plant that enjoys the sun very much and can be placed in a sunny environment all year round, but avoid exposure.

3. Watering: single trees are succulent plants, which are very cold-resistant and do not contain too much water. Usually, they should not be watered too much. If they are not dry or unwatered, be sure to dry and water again. In the hot summer season, beware of pouring heavily after exposure to the sun, which will cause fallen leaves. When the summer temperature is more than 30 ℃, the plants are dormant and semi-dormant, so watering should be controlled.

4. Fertilization: bachelors enter the dormant period in winter and should stop fertilizing. If the temperature is low, fertilization is prone to root rot. Application of rarefied liquid fertilizer containing nitrogen, phosphorus and potassium once in 7-10 days of the growing season should not be too concentrated.

2. points for attention:

Although single trees have no green leaves, the branches of single trees contain a lot of chlorophyll, which can replace leaves for photosynthesis. Single trees can be planted in the open air in the warm areas of the south, but they need to be planted in greenhouses in the north.

Pruning methods of single trees

Pruning can first be observed from the roots, some old, rotten, weak roots can be appropriately cut off, and then look at the density of the roots, if it is still very dense, you can also prune and trim on your own. Secondly, by observing the aboveground stem branches, we can first cut off some diseased branches, weak branches and residual branches, and then observe which places need to be adjusted from an overall point of view. In addition, some good stems and branches can be cut, and then a new pot of bachelors can be cultivated. But when trimming, be sure to prevent the juice from splashing on the face, which is the most important point.

Diseases and insect pests of single trees and their control

1. The main diseases of single trees are anthracnose and leaf spot. Prevention and treatment: because the disease is caused by fungal infection, so when we treat the disease of single trees, the most important method is sterilization. When there is a disease in the single trees we plant, we should first clean up the fallen branches and leaves in time to prevent the spread of germs, and then spray them with germicidal solutions such as carbendazim. In order to prevent the disease of single trees, the drainage of single trees should be done well in the rainy season to give enough sunshine.

2. The insect pests of single trees are relatively few, and the insect pests that usually occur in single trees are shell pests. Prevention and control methods: when shell pests occur in single trees, we can use the natural enemies of shell insects to deal with them. We can cultivate some ladybugs, square head beetles and other insects. These insects prey on shell insects, which can reduce the harm of shell insects to single trees. We can also use chemicals to spray singles to kill shell insects.

In fact, the breeding method of single trees is not difficult, generally starting from the aspects of temperature, soil, light and so on. Although single trees like light, high-temperature exposure is not allowed, so shading should be done in summer. In breeding, we need to strengthen the prevention and control of diseases and insect pests, timely pruning is also very important.
