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, attention should be paid 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 killing time of fresh leaves, the general spring tea is 1: 10, summer tea is 50 "~ 1, Maofeng tea is baked.

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.

Determination of aminophylline tablets
Take 20 tablets of anhydrous theophylline ┄, weigh them precisely, grind them fine, take an appropriate amount (about equivalent to aminophylline lOOmg), put them in a 200ml measuring bottle, add 0.1mol/L sodium hydroxide solution 20ml and water 60ml, shake for 10 minutes to dissolve aminophylline, dilute it with water to scale, shake well. Filter, refine the filtrate 5ml, place it in a 250ml flask, dilute it to scale with 0.01mol/L sodium hydroxide solution, shake well, and use spectrophotometry (page 17, appendix).

Processing Technology of Sichuan Border Tea
The production of border tea in Sichuan has a long history. The "Tea-Horse Law" was carried out by the officials of all dynasties since the Song Dynasty, and the "Tea-Horse Division" was set up in Ya'an, Tianquan and other places in Sichuan Province in the Ming Dynasty (AD 1371-1541). South roadside tea is made by cutting the branches and leaves of tea trees. The raw materials of fresh leaves of South roadside tea are thicker and old, which can be picked by hand or cut by knife, and the old leaves or current year branches and leaves can be picked by hand; the knife cuts the mature new branches and leaves of the current season or year. South roadside tea can be divided into Maozhuang tea and Zhuangzhuang tea due to different processing methods. Pick the fresh branches cut off

Processing and application of tea seed shell
Camellia oleifera is a unique woody oil in China. According to statistics, Camellia oleifera has an area of more than 3.47 million hectares and an annual output of 56.6 billion kg. In the tea seed shell, it contains 52.15% lignin, 30.27% pentose, 5.43% diosgenin, 2.47% tannin, 0.43% water, 0.13% oil and 9.12% other ingredients. Due to the high content of lignin and pentoses in tea seed shell, the research on the utilization of tea seed shell is still focused on the preparation of furfural, activated carbon and xylitol. 1.

Spring tea management caught six
Weeding and loosening: After 4-5 months of rain and snow attack, the soil has hardened, some have grown grass, and the soil temperature is low at this time. Therefore, weeding and loosening before spring tea mining is conducive to loosening the soil, improving the soil temperature, cutting weeds, reducing the consumption of water and nutrients, and promoting the early germination of spring tea. Weeding and loosening are generally carried out from the end of February to the beginning of March, and the depth is 10-15 cm. Application of germinating fertilizer: The time of applying germinating fertilizer should be early rather than late, and the furrows should be opened at 15-20 cm from the roots of tea trees.

Causes of outbreak of tea inchworm and its pollution-free control
Tea inchworm, also known as Archworm, measure-inch worm, hanging filariasis, belongs to the family Lepidoptera. The pest is mainly distributed in Bihu, Lixin and other tea areas in Liandu District. It is a kind of overeating pest. If the prevention and control is not in time, the output of summer and autumn tea will be seriously reduced, and the tree potential will decline, which will seriously affect the tea production. It happened every year in the past few years, but it didn't do much harm. In August 2007, the insect occurred in a large area in the tea garden in Huangling, Lixin Township, which not only seriously affected the tea yield in that season, but also caused tree potential decline and poor cold tolerance.
