Li Shu (botanist)
Prunussalicina), a fruit tree of Prunus in Rosaceae. It is a common tree species in tropical and subtropical regions, mainly distributed in southern China and Southeast Asia. Plum trees like warm and humid climate, and have low requirements for soil and strong drought tolerance. It usually grows in areas below 500 meters above sea level, and likes sunny environment, but it can also adapt to semi-cloudy environment.

Propagation method of plum tree

Sowing method

There are many propagation methods of plum trees, the most common one is sowing. First, we need to prepare the seeds of plums. Select ripe plums, take out the pulp of plums, and then wash and dry the seeds. Next, we need to prepare a well-ventilated planting container, put the seeds in the container, and then add the right amount of soil. Keep the soil moist, but not too wet to avoid seed rot. In a warm environment, the seeds will germinate after about 10- 15 days. When the seedlings grow to a certain height, we can transplant them to the outdoor nursery.

Grafting method

Besides sowing, plum trees can also be propagated by grafting. Grafting is a method of grafting buds or branches of mature plum trees to another tree. First of all, we need to choose a healthy plum tree as the rootstock, and then cut a bud or branch from the excellent plum tree we want to propagate as a scion. Next, the scion and the rootstock are grafted to ensure that their surfaces are in full contact. Fix them together with suitable grafting tape, and then wrap them with plastic wrap to keep them moist. After about 2-3 weeks, we can transplant the grafted seedlings into suitable soil.

Maintenance methods of plum trees

Soil requirements

Plum trees have low requirements on soil, but it is best to choose loose, fertile and well-drained soil for planting. If the soil is too barren, organic fertilizer can be applied before planting to provide sufficient nutrients.

water

Plum trees like humid environment, but they are not tolerant of waterlogging. During the growing season, keep the soil moist every week, but don't over-water it. Reduce the amount of watering in winter to avoid root rot.

Dressing and shaping

Pruning and shaping plum trees is an important step to maintain the beauty of trees and promote fruit growth. After the saplings grow to a certain height, we can trim the trunk to the required height for the first time. After that, every winter or early spring, we can prune weak, crossed branches and too dense branches to promote the circulation of light and air.

Control of plum pests and diseases

disease control

The common diseases of plum trees are plum rot and plum anthracnose. In order to prevent the occurrence of diseases, we can choose disease-resistant varieties before planting, keep good ventilation and light conditions, and avoid excessive watering and fertilization. If diseases are found, take corresponding preventive measures in time, such as spraying fungicides.

control of insect

Common pests of plum trees include Shi Li fly and plum moth. In order to prevent the occurrence of pests, we can check trees regularly, find and remove eggs and pests in time. Biological pesticides or chemical pesticides can be used for spraying, but attention should be paid to the use method and dosage to avoid environmental pollution.
