A Complete Analysis of the Latest Management Methods for Camellia oleifera
Camellia oleifera is a very precious oil crop in our country. The oil content of its seeds reaches more than 30%, and it can also be used for food and medicine, so its range of uses is very wide. Moreover, the vitamin E content in camellia oil is far higher than that in olive oil, so it can be said to be one of the highest-quality oils in our country. Now the planting area in our country is also becoming wider and wider, so how should Camellia oleifera be managed after planting? Below, the editor brings you the management methods for Camellia oleifera planting. Let's take a look together!
1. Loosening the soil and weeding
In the year of planting, one cultivation and weeding should be done, and afterward, at least two cultivations are needed each year. The first is after the middle of May, and then the second cultivation and weeding is carried out in early September. There will be differences depending on the planting region and weather. For example, in summer, when the ground temperature is relatively high, cultivation and weeding are not suitable. And even if it is done, only shallow hoeing can be carried out, and the cultivation depth must not exceed 5 cm. Then, as the tree age increases, the depth should be appropriately increased, and then the cultivation depth should be controlled well according to the nature of the soil. Clay soil should be hoed shallowly, while sandy soil should be cultivated deeply.
2. Fertilization management
When the base fertilizer is sufficient, no topdressing may be needed in the year of planting, and then from the second year on, topdressing should be done twice each year. Control the types of fertilizer well, and appropriately adjust the fertilizer according to seasonal changes and temperature. For example, in winter, apply quick-acting fertilizer to improve the cold resistance of the tree body and promote the overwintering of the tea trees. In spring, apply urea as topdressing, and according to the number of tea trees, the application amount per plant must not exceed 25 g, following the principle of many times and small amounts. Decide the fertilization method according to your own fertilization habits. Common ones include broadcasting and trench application. No matter what fertilization method is used, be careful not to damage the roots of the tea trees, so as to prevent affecting growth.
3. Shaping and pruning
The pruning work for tea trees should begin from the young tree stage. The shaping and pruning work for young trees first requires training the trunk. In the first two years after afforestation, all spring shoots sprouted from the terminal buds should be retained. Promote the formation of the main trunk of the tea tree, then shape the tea tree, retaining about 3 main branches at a position of about 55 cm on the main trunk. The specific number of main branches is determined according to the size of the tree body, and then branches that are too long, too dense, overlapping, or crossing are cut off. Improve the air permeability of the tea tree after pruning, enhance ventilation and light transmission, promote the photosynthetic capacity of the tea tree, increase yield, and ensure quality.
4. Appropriate intercropping
The planting spacing of tea trees during the young tree stage is relatively large. In order not to waste land resources, we can also appropriately intercrop during the young tree stage. Intercropping crops should be selected from crops with a short growth period and low water and fertilizer requirements, and it must be ensured that the intercropping crops will not compete with the tea trees for light, water, nutrients, and so on. It must also be ensured that at least 1 sq m of growth space is left for the tea trees. Relatively suitable intercropping crops include peanuts, mung beans, and so on. After maturity, they can be directly turned into the soil as green manure, and if the yield is good, they can also be sold on the market. This is not only beneficial to the growth of Camellia oleifera, improves the land utilization rate, but also allows a short-term return on investment and improves economic benefits.
During intercropping, be careful not to plant tall-stemmed or vine crops, otherwise it will affect the growth of the tea trees and lead to the opposite effect. Then, disease and pest prevention and control work should be done well, management should be strengthened, pathogens and insect eggs should be reduced, the incidence rate should be lowered, the resistance of the tea trees should be enhanced, yield and quality should be improved, and your own planting benefits should be expanded.
