Use of tea machine
In the whole process of mechanized processing of high-quality tea from fresh leaves to finished tea, it is necessary to deal with two relations: one is the relationship between heat and water vapor, and the other is the relationship between mechanical force and shape. The heat energy causes the biochemical change of the tea, and the force is to change the appearance of the tea by external force.
In the specific use, we should pay attention to:
1. Before operation, each machine should be trial-run, and observe whether the temperature and other technical parameters can meet the technological requirements of famous and high-quality tea, such as the green-killing time of fresh leaves, the general spring tea is 1 × 10 ", the summer tea is 50" ~ 1 ", and the drying time of Maofeng tea is 5 minutes and 40 minutes respectively, which can be adjusted according to the situation.
2. Tea processing in each shift begins after all the machines have reached the normal temperature. The relationship among temperature, time, leaf input and fresh leaf quality and technical elements in processing can be seen from the tea production.
3. At the end of the operation, the machine with firewood and coal structure shall be used to reduce the residual fire, and the machine will be turned off when the temperature of the main parts drops to 40 ℃ and 50 min. At the end of the tea season, it is necessary to remove furnace ash, clean machinery, add lubricating oil, and cover it with a cover for processing in the coming year.

Control of rodent damage in Codonopsis pilosula
The seedlings began to damage the ginseng seedlings when they were unearthed 5 cm. Control method: 1 part of ① 3% zinc phosphide is added to 95 parts of green vegetables, beans, rice, etc., and mix well in the evening to leave the places or holes frequented by rats. ② 0.5% bromadiolone 1 part and 3 parts of flour are evenly mixed, then cut apple, vegetable and Youtiao (cut into 1 cm), stick and mix evenly, can be put in the place where rats often move in the evening, or 2.5% methamidophos granules can be used every 667 square meters with 1500 grams of fine soil and 10 kg sprinkled on the border.

Key techniques of cultivation and management of tea in greenhouse
First, garden choice: choose flat land or gentle slope land with fertile soil, adequate water supply and good soil permeability to build a garden. It is best to choose the mountains in the north and the open terrain in the south to block the cold wind in winter and avoid the tea garden in the tuyere plain. Windbreaks should be set up in the north of the tea garden. Second, tree age: mainly strong tea garden, its tree potential is strong, the growth is strong, the tea yield is high, and the coverage of the tea garden is more than 85%. Third, the greenhouse mode: the greenhouse is mainly warm in winter, with a width of about 13 meters and a length of not.
