Key Points of Oil Tea Cultivation and Management Techniques and Detailed Explanation of Basic Knowledge

AbstractOil tea is an excellent winter nectar and pollen source plant. Its seeds can be pressed to produce high-quality tea oil, the tea cakes made from it can serve as fertilizer and pesticide, and the fruit peel can be used to extract tannin extract. Oil tea cultivation techniques: select large, plump, pest-free, high-quality seeds for planting. During the growing period, sufficient sunlight and water are required. During the planting process, attention must be paid to weeding and loosening the soil. In the early fruiting stage, pinching should be carried out, and in the full fruiting stage, attention must be paid to fertilization.

I. Oil Tea Knowledge

1. Oil tea is an evergreen tree. Because its seeds can be pressed to produce tea oil, and the oil pressed out is a pure natural green vegetable oil, it is called oil tea. The tea oil pressed from oil tea is not only a high-quality edible oil with extremely high nutritional value, capable of preventing high blood pressure, high blood lipids, and diabetes, but it can also be used as lubricating oil and rust-preventive oil.

2. The tea cakes made from oil tea can prevent and control pests and are a high-quality fertilizer and pesticide.

3. The fruit peel can be used to extract tannin extract.

4. Oil tea is also a woody edible oil crop and an excellent winter nectar and pollen source plant. It has extremely strong pollution resistance and can absorb chlorine and resist fluorine.

II. Planting Conditions

The suitable growing temperature during the flowering period of oil tea is about 12-13 degrees Celsius. It requires relatively sufficient sunlight and water. It can be planted on gentle hillsides with weakly erosive soil. Places with too many stones and overly hard soil quality are not suitable for planting.

III. Planting Methods

1. Seed selection

For oil tea seed selection, it is necessary to choose high-quality seeds that are large, plump, and free of pests and diseases. Seeds should be stored on a well-ventilated, dry surface, spread out evenly, and after threshing, stored in the upper layer of a wet sand surface.

2. Land preparation and cultivation preparation

In the year before oil tea forest establishment, carry out land preparation from May to October. According to local conditions, methods such as full land preparation and strip land preparation should be adopted. In order to store water and prevent drought, dig holes and prepare for cultivation in suitable planting sites.

3. Cuttings and grafting

(1) Oil tea is generally propagated better by cuttings or grafting. Forest establishment is generally carried out from the Beginning of Spring to Awakening of Insects. For cutting propagation and seedling raising, summer should be chosen.

(2) It is better to collect scions in the early morning. Healthy, intact branches free of pests and diseases should be selected, cut into cuttings, treated with rooting powder, and then subjected to cutting propagation.

(3) After cutting propagation is completed, watering should be carried out within 1-2 months. After this period, oil tea can heal and develop roots.

(4) After root development, the shed can be uncovered in cool weather to increase light exposure.

4. Direct seeding

If the direct seeding method is used, it is generally better to choose winter for forest establishment. Oil tea is generally raised by drilling for seedling cultivation, and seedlings can be raised in both winter and spring. Before sowing, cultivate the seedbed, apply sufficient base fertilizer, and then cover with a layer of fine fertilized soil and thin grass.

5. Weeding and loosening the soil

If the seeds germinate and emerge from the soil, the thin grass can be uncovered. Note that the timing for uncovering should be on cloudy days or in the cooler evening, and weeding and loosening the soil should be done well.

6. Shaping by pruning

Pruning for tree shape is mainly based on the open-center form. In the early fruiting stage, pinching can be carried out. In the full fruiting stage, “opening the skylight” can be used during the renewal period. Pay attention to fertilization, which can restore tree vigor.
