A, 2020 tea oil tree planting prospects?
1, value
The tea oil tree seeds contain more than 30% oil, can be used for food, medicine, candles, soaps, shampoos, etc., can also be used as a substitute for motor oil. Tea seed meal contains tea saponin, tea seed polysaccharide, tea seed protein, etc., they are chemical, light industry, food, feed industry products, such as raw materials; tea seed shells can also be made into furfural, activated charcoal, etc., the ash of the tea tree to wash the head to kill lice, including eggs; tea seed tree texture is fine, dense, heavy, heavy in the hands of the hand, very hard, it is to do the gyro, slingshot of the best materials, and because of the natural texture of the tea tree is also the production of high-grade wooden buttons. It is the best material for making gyro and slingshot.
Tea oil unsaturated fatty acid content of up to 90%, much higher than vegetable oil, peanut oil and soybean oil, and olive oil than the vitamin E content is twice as high, and contains camellia glycosides and other specific physiologically active substances, has a very high nutritional value. Tea shells or a good edible mushroom culture medium. Studies have shown that the oil tea saponin and antibacterial and antioxidant effects.
2, planting benefits
New oil tea forests with mechanized land preparation, each acre of roughly 1,000-1,300 yuan. If the land is prepared manually, it costs about 1500-2000 yuan per mu. The cost includes: seedling fee, fertilizer fee, land preparation fee, afforestation fee and so on.
Bloom in the third year, fruit in the fourth year. Fruit hanging the second year, the amount of fruit hanging exponentially, 8 years later into the high yield, stable yield period. Later on, there is a long harvest and management is relatively simple.
Fruitful period per mu a year can pick more than 1000 kilograms of raw tea fruit. Produce more than 100 kilograms of tea oil, according to the tea oil 15 yuan per catty calculation, the annual mu output value of more than 3,000 yuan. And tea shells, tea wither has comprehensive utilization value. Overall, 2020 tea oil tree planting prospects are still very considerable.
So, planting oil tea once invested in long-term income, high economic value, ecological benefits, market potential, good prospects for development.
Second, tea oil tree planting technology
1, selection of land preparation
The tea oil tree is light-loving, acidic species, should be chosen to sunshine and pH value of 5-6.5 of the soil afforestation. Choose the method of land preparation according to local conditions, apply enough basic fertilizer, and irrigate the bottom moisture well.
2, seedling planting
Tea oil tree afforestation survival rate of high and low, and air humidity and soil moisture is closely related, it is best to choose cloudy or drizzly weather afforestation, with the up and build.
3, field management
In the process of plant growth should be timely plowing and weeding, so that adequate water and fertilizer, NPK ratio and moisture should be reasonably matched, fertilizer spraying after the new high-fat film, to enhance the effectiveness of the fertilizer; regular spraying of the tree protection generals, which can effectively prevent the tree cortex of the disease and pests, and enhance the plant's ability to prevent pests and disease resistance, to protect its healthy and strong growth; with the King of the promotion of flowers No. 2 coated with the ring cutting mouth, can be replace the traditional ring stripping technique to achieve tip control, disinfection, complete eradication of large and small years, and promote a large number of high-quality flower bud differentiation in order to improve the fruiting rate of fruit trees.
4, fertilization technology
Related research shows that every 100kg of branches and leaves of oil tea forest need 0.9kg of nitrogen, 0.22kg of phosphorus, 0.28kg of potash; every 100kg of fresh fruits need 11.1kg of nitrogen, 0.85kg of phosphorus, and 3.4kg of potash; every 1430kg of fresh fruits need to be absorbed from the soil with 158.7kg of nitrogen, 158.7kg of phosphorus, and 3.4kg of potassium; every 1430kg of fresh fruits need to be absorbed from the soil. 158.7kg of nitrogen, 12.0kg of phosphorus and 48.6kg of potassium are needed to be absorbed from the soil for every 1430kg of fresh fruits produced; in order to adapt to the needs of nutritive growth and mass fruiting of the tree during the fruiting period, fertilizers should be applied with a reasonable proportion of nitrogen, phosphorus and potassium, generally N:P2O5:K2O=10:6:8; the total amount of quick-acting fertilizers applied to each plant every year is 1KG, and organic fertilizers is 15KG; the increased application of organic fertilizers not only improves the soil's physicochemical properties effectively, but also cultivates the ground's strength and increases the number of soil The number of microorganisms, prolong the fertilizer effectiveness, but also to improve the fruit oil content.
In the application of fertilizer on the basis of, but also according to the year, soil conditions and tree fruiting amount of appropriate increase some of the appropriate amount of foliar spraying, on the promotion of flowers and fruits, regulating the tree, improve the quality and improve the resilience of the great help. Foliar fertilization with a variety of trace elements, potassium dihydrogen phosphate, urea and a variety of growth regulators based on the dosage, the role of a small amount of fast, it is appropriate to carry out in the morning or evening, focusing on spraying the back of the leaf effect is better.
4, control of pests and diseases
The main prevention and control of anthracnose, soft rot, tea moths, stem borers, etc., according to the incidence of pests and diseases, in a timely manner, according to the requirements of the plant protection with targeted agents plus the new GHG film for prevention and control.
The role of oil tea tree is wide, there is a high value of the application, planting in recent years is also quite hot, but the initial need to invest in 4 years or so to the results, is not suitable for the hands of the lack of funds for the novice.
