How to raise potted orange trees in the north

1. Choose flowerpots;

Generally, the flowerpot of potted fruit trees is round, because the round flowerpot is beneficial to the root system to spread evenly around, and at the same time, the container needs water seepage and good air permeability to ensure the oxygen demand for root growth, and to prevent the root rot caused by water accumulation in the container.

among all kinds of containers, the vegetarian pot is the most suitable for planting fruit trees. When using containers of other materials, in order to overcome the shortcomings of poor air permeability, coarse sand with a thickness of 5 cm can be paved at the bottom of the basin, and a new layer of tiles can be padded along the inner wall, and then trees can be planted by filling the soil.

2, soil matrix;

Generally, the basin soil suitable for the growth of orange trees is slightly acidic (PH value is 4,5-7,5) and sandy loam or sandy soil rich in humus. During the preparation, 4 parts of ripened pastoral soil, 2 parts of river sand and 1 part of plant ash are fully and evenly mixed, ground and sieved. The culture soil should be disinfected before use, such as cooking disinfection, baking disinfection or drug disinfection (sprinkling 1,5% formalin).

3, lighting control;

orange tree is a light-loving and warm fruit tree, so the pot tree must be placed in a place with sufficient light and good ventilation to promote the elongation of plant growth points, form high-quality flower buds and improve the fruit setting rate. Orange trees have poor cold tolerance and must be put into plastic greenhouses for wintering; In summer, when the temperature is above 35℃, cover the sunshade net and spray water to cool down from 9: am to 4: pm, otherwise it will easily cause young fruits to fall off.

4, fertilizer and water management;

1) water. Different fruit trees have different requirements on the pH value of water. Generally, 4,5 ~ 7 is suitable for orange trees, and ferrous sulfate can be used for correction. The temperature difference between water temperature and soil should not exceed 5℃. During the growing season, watering should be carried out before 1 am or after 4 pm. Water once a day on sunny days in summer. If the soil is dry, water should be replenished once that day. Water once a day in spring and autumn, and once every 2 ~ 5 days in early spring and late autumn depending on the soil moisture in the basin; Control watering in winter.

2) fertilization. Be diligent because of the trees, the sky and the thin soil. Trees with strong fertilizer tolerance, large growth and many fruits should be fertilized more, and vice versa; No fertilization during dormancy; Fertilization should be applied more in the pot soil with low fertilizer content or long-term dumping, and less in the pot soil with high fertilizer content

4, and the pot soil should be replaced;

Because the nutrients in the pot soil are absorbed by the fruit trees or washed away by frequent watering, the pot should be emptied in time and replaced with new nutrient soil every 2-3 years. After the soil mass is reversed, the old roots with a thickness of 2-3 cm around the pot soil are cut off, the organic fertilizer and the nutrient soil are mixed evenly to fill the bottom, and then the soil mass is brought to the pot, and the surrounding soil is filled with rich soil, and it is watered once.

5, trimming and shaping;

1) Tree selection: The tree shape of potted orange trees can create imaginative trees, such as natural round head shape, tower shape, one-branch cliff shape, two-branch antlers shape, three-branch cup shape, weeping willow shape, dragon curve shape and so on. Make it not only beneficial to the result, but also have aesthetic effect and improve its ornamental value.

2) spraying and shaping: applying chemical control technology to dwarf the tree. In summer, in the vigorous growth period of potted orange trees, plant growth retardants (such as chlormequat chloride and paclobutrazol) should be sprayed on the leaves for 2-3 times, which can make the branches stout, the internodes short and the plants dwarf.

In addition, the measures to promote flowering and dwarfing and pruning by shape mainly include: wiping buds, coring, taking branches, bending branches, ring cutting, retracting, renewing and pulling branches. And through the angle of opening branches and thinning long branches, dense branches and invalid branches, the illumination is enhanced and the ideal tree shape is formed.

6, pest control;

Pot soil is required to be "loose, light and fat", which is generally composed of garden soil, fine sand, sawdust or crushed straw in proportion, and then a proper amount of chicken manure, cake fertilizer, compound fertilizer and trace elements are added and mixed, and the pH value of pot soil is 5.5 ~ 7 after fermentation and decomposition (the pH value should be adjusted according to different tree species).

7, flower and fruit period management;

When the number of flower buds of orange trees is large, the flowers should be thinned at the bud-pregnant stage and the fruits should be thinned after the physiological fruit-dropping stage. If the number of flower buds is small, you can leave more flowers. At the same time, artificial pollination is needed.

8, overwintering management;

In the case of no freezing injury in winter, orange trees generally don't need to overwinter indoors, so they can naturally hibernate outdoors. In order to prevent freezing injury, the soil can be watered once before freezing, and then the whole container can be wrapped in a straw bag for cold protection, or it can be buried in a ditch.

attention should be paid to the following aspects when raising potted orange trees:

1. Changing pots: according to the size of orange trees, choose a round flowerpot with a larger mouth, which is convenient for fertilizing and loosening the soil for the orange trees in the future, and the flowerpot has better air permeability and water permeability, so as to ensure the oxygen demand for the growth of orange tree roots.

2. Soil: When replacing the flowerpot, the soil of the flowerpot should be replaced at the same time. Pour out the original pot soil, add some sandy loam or sandy soil rich in humus, some organic fertilizer, etc. to the old pot soil, and then put the pot soil back into the flowerpot.

3, illumination: orange tree is a kind of fruit tree that likes sunshine. When planting potted orange trees at home, the potted orange trees should be placed in a sunny and well-ventilated environment, which is generally more suitable on the balcony. Let the orange tree bask in the sun, which can promote the growth and flowering of orange trees.

4. Pruning: If you want the potted orange tree to look good, you need to prune the orange tree from time to time, and prune some branches of the orange tree, so as to keep the orange tree in a good shape and improve its aesthetics.

Bonsai, one of the outstanding traditional arts in China, is a work of art that uses plants and rocks as basic materials to express the natural landscape in the pot.

it takes plants, rocks, soil, water and so on as materials, and through artistic creation and gardening cultivation, it typically and intensively shapes the beautiful scenery of nature in the basin, achieving the artistic effect of shrinking the land into an inch and seeing the big in the small, and expressing its profound artistic conception with the scenery, just like a three-dimensional beautiful miniature landscape area.

bonsai originated in China. Generally, there are two types of bonsai: stump bonsai and landscape bonsai. Bonsai is composed of three elements: landscape, basin and shelf, which are interrelated and mutually influenced. People regard bonsai as "three-dimensional painting" and "silent poem".
