The camellia oil tree is a pure natural high-grade oil unique to my country. It grows in the mountains and hilly areas of the subtropical areas of southern China. It is named because its seeds can be pressed for oil for consumption. So, what are the prospects for tea oil tree planting in 2020? Comes with planting technology!
1. What are the prospects for tea oil tree planting in 2020?
1. Value
Tea oil tree seeds contain more than 30% oil, which can be used for food, medicine, candle making, soap, shampoo, etc., and can also be used as a substitute for engine oil. Tea seed meal contains tea saponin, tea seed polysaccharide, tea seed protein, etc., which are raw materials for chemical industry, light industry, food, feed industry products, etc.; tea seed shells can also be made into furfural, activated carbon, etc., and the ash of tea tree Washing your hair can kill lice including eggs; the tea tree is thin, dense and heavy, heavy and hard in the hand. It is the best material for making tops and slingshots, and because it has the natural texture of the tea tree, it is also the best material for making tops and slingshots. High-grade material for making high-grade wooden buttons.
The unsaturated fatty acid content of camellia oil is as high as 90%, which is much higher than rapeseed oil, peanut oil and soybean oil. The content of vitamin E is twice as high as that of olive oil. It also contains specific physiologically active substances such as camellia glycosides, which has Extremely high nutritional value. Tea shells are also a good culture medium for edible fungi. Research shows that tea saponin also has antibacterial and antioxidant effects.
2. Planting benefits
If mechanized land preparation is used for a new Camellia oleifera forest, it will cost about 1,000-1,300 yuan per mu. Manual land preparation will cost about 1,500-2,000 yuan per mu. Expenses include: seedling fees, fertilizer fees, land preparation fees, afforestation fees, etc.
It will bloom in the third year and bear fruit in the fourth year. Starting from the second year of fruit bearing, the amount of fruit bears increases exponentially, and after 8 years it enters a period of high and stable yield. There will be long-term harvests in the future, and management will be relatively simple.
In the high-yield period, more than 1,000 kilograms of raw tea fruits can be picked per mu per year. More than 100 kilograms of camellia oil are produced. Calculated at 15 yuan per kilogram of camellia oil, the annual output value per mu is more than 3,000 yuan. Moreover, tea shells and tea leaves also have comprehensive utilization value. Generally speaking, the prospects for tea oil tree planting in 2020 are still very promising.
Therefore, growing camellia oleifera can provide long-term returns from a single investment, with high economic value, good ecological benefits, large market potential, and good development prospects.
2. Camellia oil tree planting technology
1. Site selection and preparation
Camellia oil tree is a light-loving and acid-loving tree species. It should be selected with sufficient sunshine and pH. Soil silviculture with a value of 5-6.5. Choose soil preparation methods according to local conditions, apply sufficient base fertilizer, and irrigate the soil with good soil moisture.
2. Planting of seedlings
The survival rate of camellia oil tree afforestation is closely related to air humidity and soil moisture. It is best to choose cloudy or light rainy weather for afforestation. .
3. Field management
During the growth of plants, timely cultivating and weeding should be carried out to ensure sufficient water and fertilizer, and the NPK ratio and moisture should be reasonably matched. After fertilization, spray a new high-fat film to enhance Fertilizer effect; regular spraying of Tree Protector can effectively prevent tree bark diseases and insect pests, enhance the insect and disease resistance of the plant, and ensure its healthy and robust growth; apply Kao Kao No. 2 on the girdling opening, which can replace the traditional girdling technique. Achieve shoot control and disinfection, completely eradicate large and small trees, promote the differentiation of a large number of high-quality flower buds, and increase the fruit setting rate of fruit trees.
4. Fertilization technology
Relevant research shows that for every 100kg of branches and leaves produced by the Camellia oleifera forest, 0.9kg of nitrogen, 0.22kg of phosphorus and 0.28kg of potassium are needed; for every 100kg of fresh fruit produced It requires 11.1kg of nitrogen, 0.85kg of phosphorus and 3.4kg of potassium. For every 1430kg of fresh fruit produced, 158.7kg of nitrogen, 12.0kg of phosphorus and 48.6kg of potassium need to be absorbed from the soil. In order to meet the needs of tree vegetative growth and large fruiting during the fruiting period, fertilization requires a reasonable ratio of nitrogen, phosphorus and potassium, generally N:P2O5:K2O=10:6:8. A total of 1KG of quick-acting fertilizer and 15KG of organic fertilizer are applied to each plant every year. Increasing the application of organic fertilizers can not only effectively improve the physical and chemical properties of the soil, fertilize the soil, increase the number of soil microorganisms, prolong the effectiveness of chemical fertilizers, but also increase the oil content of fruits.
On the basis of top dressing, some appropriate amount of foliar spraying can also be applied according to the year, soil conditions and the number of fruits on the tree to promote flowers and preserve fruits, adjust tree vigor and improve quality. And goes a long way in improving stress resistance.
Foliar fertilization is mostly based on various trace elements, potassium dihydrogen phosphate, urea and various growth regulators. The dosage is small and the effect is fast. It is suitable to be carried out in the morning or evening. The effect is better when spraying on the back of the leaves.
