Cultivation techniques of Malus vulgaris

Malus balengensis is a fruit treasure with a long history of cultivation in China, also known as Huailai Begonia, Haihong and so on. It is a deciduous tree plant belonging to the apple genus of Rosaceae. It has a large thin skin and a single fruit weighs 814 grams. It is named because the fruit is flat and round. Affected by a variety of factors, the area where Begonia is concentrated on the earth is very small. Let's take a look at the cultivation techniques of Begonia.

Growth habits of Malus balengensis

Malus balengensis tree is strong and easy to manage, with developed root system, more fibrous roots, cold resistance, drought resistance, waterlogging resistance, saline-alkali resistance, disease and insect resistance, barren resistance, water and humidity resistance, high survival rate of transplanted seedlings, rapid growth, suitable for all kinds of soil quality, and wide adaptability. no matter flat land, hillside, hilly, sand wasteland, it can plant Malus angustifolia trees, and the life span in normal management is more than 180 years.

Propagation techniques of Malus balengensis

1. Grafting: rootstocks generally use seedlings, branch grafting or bud grafting. Branch grafting is carried out before sprouting in spring and can be cut and split. The scion selects the fully developed one-year-old branch, takes its middle section, and then covers it with fine soil without scion. The bud grafting is carried out from July to September in autumn, and the T-shaped connection is often used. about 10 days after that, the bud is fresh and the petiole falls immediately, and it can be cut off and tied after a few days.

2. Ramet: more than before sprouting in early spring or after defoliation in autumn and winter, the tiller strips sprouting from the rhizosphere were dug up and cut into several individual plants, or 2-3 root sprouting strips were transferred into a cluster. Attention should be paid to preserving the fibrous root of the tiller to ensure survival after planting. After planting, water should be watered once in time, pay attention to soil moisture conservation, and shade if necessary.

3. Striping: pressing is carried out in spring, the seedlings can climb to the ground and press into the soil, and the big seedlings are cut with a sharp knife to keep the soil moist, and the mother plant is cut off after the root is cut off and planted separately.

4. Root insertion: root insertion propagation is mainly carried out during transplanting and digging seedlings. The thicker main root is cut into 10 cm and 15 cm into a section, which is buried in shallow soil and covered with grass to keep moisture, so it is easy to survive.

Cultivation techniques of Malus vulgaris

1. Soil: Malus chinensis is generally planted on the ground, and it can also be potted to make bonsai and be planted in spring. Because of avoiding water stains, it should be planted in a slightly higher terrain where it is not easy to accumulate water and become sunny. The soil is neutral and alkaline, and the pH value is not less than 7. The soil is required to be loose, but not too fertile, which can easily lead to futile growth and reduced flowering. Planting holes should be determined according to the size of the root system, not too deep and too large, so that it is better to stretch the root system. The planting depth should be 10% water from the ground. It is best to plant with a mass of soil and pour enough water after planting.

2. Light: Malus balengensis is suitable to grow in the environment with sufficient light, but it grows badly in the shade environment. If potted crabapple trees are planted, they should be placed in a place with plenty of light during the growing period. In winter, it will not suffer frost damage under the condition of-15 ℃ low temperature, so it can live in the open field outdoors. However, in the unusually cold winter, it is necessary to take cold prevention measures.

3. Fertilizer and water: Malus balengensis was watered and fertilized. Big fertilizer should be applied once a year after defoliation in autumn to supplement the nutrients consumed by flowers and fruits, and it is better to apply rotten organic fertilizer. At the same time, combined with winter irrigation. Before the spring bud shade moves, the organic fertilizer is applied once, and watered once. The way of fertilization varies with the age of the tree, the young tree is picked and fertilized in a ring shape, the ring is less than 100 cm from the root of the tree, the older tree is dug and fertilized radially, weeds are removed in the combination of the old tree, the organic fertilizer is sprinkled under the crown, and the fertilizer is turned into the ground 30 cm after the application. After flower fade, phosphate and potassium fertilizer was applied twice to ensure a certain fruit setting rate. At the same time, pay attention to watering.

4. Pruning: the flower buds of Malus vulgaris are mostly differentiated from the terminal buds, and the medium and short fruit branches are the main flower branches, so the medium and short fruit branches should be retained. The long branches should be cut short, at the same time, the dense branches, dry and withered branches, disease and insect branches should be cut off, and then pruned according to the desired tree shape. If you want to make the crown of begonia perfect, then dense and sparse, cut off the dense branches, and cut down the sparse parts of the branches, in order to make it more side branches, simple vacancy.
