The Latest Cultivation Techniques and Methods Tutorial for Tung Oil Tree

The tung oil tree is a deciduous tree of the Euphorbiaceae family and a plant with a very large tree form, reaching up to 10 m in height. The tung oil tree is a very important industrial oil crop in China, and China is also a major exporter of tung oil. In addition, the fruit peel of the tung oil tree can be used to extract potassium carbonate to make activated carbon and so on, making it a crop with relatively high economic value. So how should the tung oil tree be cultivated? Below, the editor brings you the cultivation techniques for the tung oil tree. Let's take a look!

1. Site selection and land preparation

First, we should choose sandy soil with deep, loose and fertile soil layers, normal drainage and irrigation, and rich organic matter for planting. Then carry out land preparation on the soil. According to the terrain of the planting site, choose the correct land preparation method. For example, if you choose to plant on a plot with a slope of less than 25 degrees, then you should open up the land along the contour lines of the hillside while controlling the width well, and a ditch should be retained every 4 rows to facilitate later water management. Then control the planting density, dig the planting trenches well, and pay attention to the width and depth, completing the preparatory work before planting.

2. Timely seedling raising

The main seedling raising method for the tung oil tree is field seedling raising. The field terrain should not be too high, and sowing should be appropriately dense. After collecting the seeds, choose good soil, prepare the seedling bed properly, then level the bottom of the seedling bed. After leveling, sow densely in one layer to prevent overlapping. After sowing, cover with about 12 cm of fine soil so that the seedling bed is higher than the paths on both sides. Grass material may be appropriately covered to improve soil heat and moisture retention and prevent field mice and so on. Also dig drainage ditches well to prevent water accumulation in the field. In early spring of the second year, select seeds that have already germinated to begin afforestation. Those that have not germinated should continue to be sprouted, and taken out again after about a week. Continue this for about three weeks in total, and after three weeks the seeds that have not germinated can be discarded.

3. Lifting seedlings and transplanting

When lifting and transplanting tung oil tree seedlings, be careful not to damage the seedling roots. Especially in field seedling raising, the time for lifting seedlings should be chosen after rain, when the soil is relatively moist. If the soil is relatively dry, then about three days before lifting the tung oil tree seedlings, water thoroughly to make the soil moist. Ensure that the seedling roots are not fatally damaged when lifting seedlings. If the planting site is relatively close, then we should try to use the method of transplanting with soil. If the distance is relatively far, then the roots should be moistened with mud slurry to prevent the roots from drying out during transplanting and causing death.

4. Tending and management

If we want to grow high-yielding tung oil trees, then we must ensure a reasonable tree structure. Within 4 years after planting, loosening the soil and weeding should be carried out at least twice a year. The depth of soil loosening must not be less than 15 cm. The removed weeds can be placed around the tree to improve the soil's water and fertilizer retention. Also, each time the soil is loosened, one topdressing is needed to ensure sufficient nutrients to promote the growth of young trees and cultivate tree shape. Because the tree form is relatively small in the early stage, intercropping may be appropriately carried out during the young tree stage to improve soil utilization. Intercropping crops should be low-stalk crops such as peanuts and broad beans, but continuous cropping should not be practiced, and they should not be placed tightly against the trunk, so as to prevent affecting the growth of the tung oil tree.

The above is a brief introduction to the cultivation techniques for the tung oil tree. The growth period of the tung oil tree is very long, so the time to profit will also be relatively long. During planting, management must be strengthened, and pest and disease control work must also be done well.
