Cultivation techniques of Red Heart Orange

Red orange is what we call blood orange. This orange is orange red or purple when cut open. Its vitamin C content is extremely high. Now the market demand is high, attracting many people to plant it. What is the cultivation technique of red orange?

Cultivation Techniques of Red Orange

1. The garden should be selected from slightly acidic soil with loose and deep soil, rich in organic matter, good permeability of subsoil, low groundwater level, convenient transportation of orchard, water source for drought resistance nearby, avoiding tuyere zone and planting windbreak forest.

2. Mountain orchards should be opened with large holes or trenches. The hole opening specification is one meter long, one meter wide and 0.8 meter deep. The trench should be carried out according to the contour line. Paddy orchards should be built with high piers and deep drains to prevent ponding from damaging trees.

3. Choose healthy virus-free seedlings.

4, planting method to wide row narrow plant to carry out, the requirements of row spacing is not less than 4 meters, plant spacing between 2-3 meters, planting 55-80 plants per mu.

5. If it is pulp root seedling, it should be planted in early winter or spring. The root system of the planted plant should not be in direct contact with the base fertilizer. It should be separated with new soil. It should be transplanted with soil as much as possible. It can protect the roots and leaves. After planting, it should be watered with enough root water, trimmed tree tray, covered with straw, etc. Continue to drench 2-3 times depending on the weather and soil moisture, keep the rhizosphere moist until the seedlings grow steadily.

6. Young trees should be mainly treated with water and fertilizer, and the goal of management is to rapidly increase the crown. With the increase of crown, the amount of fertilizer per plant should be increased appropriately, and urea and compound fertilizer should be applied alternately to promote the increase of branches and leaves as soon as possible. Organic fertilizer should be applied to three-year-old trees in combination with hole enlargement and soil improvement, and the amount of fertilizer should be increased gradually with the increase of branch number.

7. Trees with many fruits should pay attention to increasing the amount of fertilizer applied to prevent premature aging caused by excessive initial fruit bearing. The standard of proper amount of fertilizer is that the fruit can expand normally and release sufficient autumn shoots on time, and the young trees should be able to release summer shoots. Drought should be irrigated in time.

8. Young trees should not be cut too much, and the growth of tree type should be guided by the method of selecting buds. The height of trunk should be controlled at 30-50 cm, and 3-5 main branches should be selected. Fruit trees should pay attention to suppressing the growth of top upright branches to prevent tree type from standing upright and too high.

9. Selecting the number of flowers and fruits and adjusting the relationship between vegetative growth and reproductive growth are the key to fruit preservation. The trees with too many flowers should be thinned, and the flowering branches with leaves should be kept as far as possible; the fruit trees with less flowers should be removed from excessive vegetative branches to prevent excessive vegetative growth and fruit drop.

Red orange cultivation technology is simply introduced here, I hope to have a certain reference value for everyone, at the same time according to the actual need to consult relevant people.
