Choose a leeward sun, warm and humid mountainous terrain at an altitude of 500 to 800 meters. The soil pH is 5.0 to 6.8, the soil is deep and fertile, and the organic matter content is above 1.5% in the medium-acid soil. (3) Cultivation management. 1. Planting: Choose the mountain that is suitable for site conditions and deep application of organic fertilizer. The best time for planting Eucommia ulmoides seedlings is from late October to the end of February. 2. Density: The mountain Eucommia forest is 120 to 220 plants/666.7 m2 (mu), and the fast-growing Eucommia ulmoides forest is 1000 to 1200 plants/666.7 m2 (mu). 3. Management: Weeding and weeding at the right time to keep the soil loose. Under the possible conditions, the farmer's fertilizer is more than 500kg, and the cake fertilizer is about 150kg. 4. Trim: Control the top advantage and expand the three-dimensional picking surface. Young forests need to be trimmed 3 times, and fast-growing forests are trimmed once a year to ensure tree growth and easy picking of fresh leaves. (4) Fresh leaves are picked. From March to April, green leaflets are used to make refined tea; from May to October, green leafy tea is made. The leaf-leaf device needs to be clean and ventilated.

Avalanche: The time is 4 to 8 hours, the thickness is not more than 3 cm, the room is ventilated indoors, avoiding direct sunlight, and the degree of apricot is about 72% of the water content of the tea. 3. Killing: high temperature killing, first high and then low, young leaves old kill, old leaves tender kill, the temperature of killing is controlled at 210 to 230 °C, the water content of the green leaves is about 60%. 4. 揉捻: The machine is cold and cold, and the pressure is light-heavy-light, alternating, with light squatting as the main to prevent hanging wire. The teabag is changed to pulverize, and the thickness of Eucommia tea is controlled between 15 and 50 mesh. 5. Erqing: The water content of Eucommia ulmoides tea leaves is reduced to about 40% with a dryer with a leaf thickness not exceeding 0.5cm and a temperature adjusted to 100 to 120 °C. 6. Modeling: The tea pot is shaped by the machine to make the rate of the finished product more than 90%. 7. Foot Dry: Dry with a dryer at 80 to 90 ° C to make the water content less than 7%. 8.
