Management methods of Camellia oleifera

Camellia oleifera is a very precious oil crop in China, its seed oil content has reached more than 30%, and can also be edible, pharmaceutical, etc., its use is very wide. And the content of vitamin E in tea oil is much higher than that in olive oil, which can be said to be one of the best quality oil in China. Now the planting area of our country is getting wider and wider, so how to manage it after planting Camellia oleifera? The following editor brings you the management method of Camellia oleifera planting, let's have a look!

1. Loosen the soil and weed

Intertillage weeding should be done once in the year of planting, and then at least twice a year in later planting, the first after mid-May, and then the second intertillage weeding in early September. It varies according to the planting area and the weather, for example, the soil temperature is higher in summer and it is not suitable to carry out intertillage weeding. And even if carried out, only a shallow hoe can be carried out, and the depth of intertillage should not exceed 5 cm. Then, with the increase of tree age, the depth should be properly deepened, and then the intertillage depth should be controlled according to the nature of the soil. The clay should be hoed shallowly and the sand should be ploughed deeply.

2. Fertilization management

In the case of adequate base fertilizer, there is no need for topdressing in the year of planting, and then topdressing twice a year in the following year. Control the variety of fertilizer, adjust the fertilizer according to the seasonal change and temperature, such as winter topdressing quick-acting fertilizer, improve the cold resistance of the tree, and promote tea overwintering. According to the amount of urea topdressing in spring, the amount of urea per plant should not exceed 25g, following the principle of multiple and small amounts. According to their own fertilization habits to determine fertilization methods, the common are sprinkling and ditch application, no matter what kind of fertilization methods should be careful not to hurt the roots of tea trees to prevent affecting the growth.

3. Shaping and pruning

The pruning of tea trees should be carried out from the young trees, and the work of shaping and pruning of young trees should be done first, and all the spring shoots of terminal buds should be preserved in the first two years of afforestation. Promote the tea tree to form a trunk, then shape the tea tree, and retain about 3 main branches at the position of about 55 cm of the trunk. The specific number of main branches is determined according to the size of the tree, and then the branches such as overlength and density, overlap and intersection are cut off. Improve the permeability of tea shears, enhance ventilation and light transmission, promote the photosynthetic capacity of tea trees, increase yield and ensure quality.

4. Appropriate intercropping

The planting spacing of tea trees in the young stage is relatively large, in order not to waste land resources, we can also intercropping properly in the young stage. Intercropping crops should choose crops with short growth period and low demand for water and fertilizer, and ensure that intercropping crops will not snatch light, water and nutrition from tea trees. We should also ensure that there is at least 1 square meter of growth space for tea trees, and the more suitable intercropping crops are peanuts, mung beans and so on. After maturity, it can be turned directly into the soil as green manure, and those with good yield can also be sold on the market. It is not only beneficial to the growth of Camellia oleifera, improve the land utilization rate, but also recover the cost in a short time and improve the economic benefit.

When intercropping, we should pay attention not to plant tall stalks and vines and other crops, otherwise it will affect the growth of tea trees, leading to counterproductive. Then it is necessary to do a good job in the prevention and control of diseases and insect pests, strengthen management, reduce the eggs of bacteria and insects, reduce the incidence of disease, enhance the resistance of tea trees, improve yield and quality, and expand their own planting benefits.
