1, tea cultivation methods Tea cultivation conditions: requirements for climate: sunlight: light is the primary condition for the survival of tea trees, neither too strong nor too weak, and has a special hobby for ultraviolet rays, so high mountains produce good tea. Temperature: first, the temperature, and second, the ground temperature, the daily average temperature 10 degrees Celsius; The minimum temperature shall not be lower than-10 degrees Celsius. Moisture: Adequate rainfall is a necessary condition. But too much will also adversely affect the quality. Requirements for soil: Generally, the thickness of the soil layer is greater than 1 m and does not contain limestone, and the organic matter content is greater than 1%-2%, so it has good air permeability, water permeability or water storage performance. The PH value is 4.5__6.5. Topographic requirements: The topographic conditions of tea garden mainly include altitude, slope, slope direction, etc. With the elevation, the temperature and humidity have obvious changes. In a certain height mountain area, abundant rainfall, abundant clouds, high air humidity and diffuse light intensity are beneficial to the growth of tea trees, but the higher the better, there will be freezing damage above 1000 meters. Generally, it is better to choose the south slope. The slope should not be too large, generally less than 30 degrees.

2. Tea planting time and specifications: the planting time is in the middle and late of this year 10 or the spring of the following year (March). Specification: Unicast-planting 3500-4000 equal seedlings per mu, and double sowing-planting 7000-8000 tea seedlings per mu. We advocate promoting the "early and fast method" to dual broadcasting. Training purpose: "1.

3. Tea garden management: apply base fertilizer, open planting ditch before seedlings, apply organic fertilizer (pigsty or cake fertilizer plus urea) of 250-300 kg +30 kg per mu, and then apply organic fertilizer of 300 kg +30 kg per mu every year. Planting and pruning: the planted tea seedlings are pruned in a fixed way, generally at the height of 15~20CM from the ground, and the height of 10CM is increased on the basis of the previous year in the second and third years. Pest control: prevention first, combining prevention with control. In order not to pollute tea leaves and pesticide residues, we strongly advocate lighting black tube lamps in tea gardens to trap and kill pests (moths), and the effect is ideal. When spraying new pesticides with low residue such as Uranus and Bataan, we must master the safe concentration.

4. Tea planting technology: according to a certain density (3,000-8,000 plants per 666.7 square meters), plant double rows and double plants (or single row and double plants). Then according to the management of fertilization, pest control, shaping and pruning in each growing season (mainly shaping and pruning in the first year and the second year, so that tea trees gradually form tea awns).

5. Use "planting" to prevent insects. That is, adopt appropriate planting methods to reduce the occurrence of pests and diseases. For example, when a new garden is opened, seedlings without pests and diseases are used, and a new high-fat film solution is sprayed to drive away underground pests and diseases, isolate virus infection and improve the ability to resist natural disasters. Try to use cluster planting or strip planting to avoid over-dense planting and create a good ecological environment for tea gardens; Reasonable intercropping in tea gardens can prevent large-scale single planting, thus maintaining rich natural vegetation and reducing the probability of large-scale occurrence of pests and diseases.

6. Collect (cut) pests. Timely picking, reasonable pruning, timely application of corpus callosum antiseptic film to cut the mouth, promote wound healing and prevent bacterial invasion and infection. It can improve the ventilation and light transmission conditions of tea gardens and inhibit the occurrence of whiteflies and scale insects under wet or closed conditions. For leaves with insect buds, they should be harvested again and forcibly. Pick as many leaves as possible in summer and autumn. If there are many pests in autumn, you can extend the picking and postpone the closing of the park appropriately.

7. Use fertilizer to resist insects. The application of organic nitrogen fertilizer can improve the resistance of tea trees to tea orange gall mite; The application of lime is not conducive to the survival of thrips and leafhoppers; Phosphate rock powder extract can kill red spider as root topdressing. Re-apply base fertilizer, reasonably topdressing spring fertilizer, summer fertilizer and autumn fertilizer, giving priority to organic fertilizer, supplemented by chemical fertilizer, applying nitrogen, phosphorus and potassium in a balanced way, paying attention to drainage and flood prevention, irrigation and drought prevention, and spraying Zhuangganling to make plants strong and prosperous. It can significantly improve insect resistance, reduce the dosage of pesticides and fertilizers, and reduce residual toxicity.
