First, green tea picking technology
1, picking and retention combined. The leaves of tea leaves are the main organs of photosynthesis, and the right amount of mature leaves in the tea tree is a reasonable basis for maintaining tea yield and quality. For this reason, while picking tea leaves, it is necessary to pay attention to properly setting aside new leaves. It should be ensured that a new batch of fresh leaves is left on the tea tree each year, and after it matures, it forms the main place for the synthesis of nutrients. Currently, China's famous teas are popular, and as much as possible, the famous fresh tea leaf raw materials should be used during the spring tea. Summer and autumn teas can be used to pick the famous teas or bulk tea raw materials, but they should leave them at the summer tea leaves. leaf. In alpine tea gardens or tea gardens with poor growth on low hills, leaf picking should be reserved in the later period of spring tea, and summer or autumn teas should be harvested or not collected. Parks should be closed earlier and concentrated.
2. Take both output and quality when picking. When picking tea, it is necessary to emphasize the combination of quality and quantity of fresh leaves, strict selection of standards, prevention of pollution and deterioration of fresh leaves, guaranteeing the quality of finished tea and satisfying the market demand for tea.
3, tea extract summary of the place, according to demand. Different planting varieties and different fertilization levels, tea plantation environment and climate conditions are different, resulting in a large difference in the growth of tea trees in the tea garden, while different teas have different requirements for raw materials of fresh leaves. Therefore, the tea picking standards, quantity, and picking methods should be differentiated according to the growth conditions of tea plants and the requirements of fresh tea leaves for processed tea. It is necessary to have a flexible grasp of the location, timing, and different levels of processed teas and grades. For example, if the tea plantations are pruned in young ages, the use of toppings should be adopted within a certain period of time. For those tea plants with weaker tree vigor, more leaves can be properly maintained, while for well-grown tea plantations, normal picking can be carried out.
Second, the fresh leaves transport technology points Fresh leaves is the basis for the formation of tea quality, in addition to tea processing technology, the quality of tea depends mainly on the quality of fresh leaves, good after the picking of fresh leaves transport, is guaranteed to provide pollution-free tea processing One of the basic conditions for high quality fresh leaf raw materials should be given high priority.
When picking fresh leaves by hand, it is required that the container for fresh leaves is a breathable bamboo basket or bamboo basket. It is not allowed to use a gas-tight container such as a plastic bag or a nylon woven bag to hold fresh leaves, so as to prevent the fresh leaves from being contaminated by heat. In particular, the picking of famous fresh tea leaves should pay attention to this point. When fresh leaves are picked up by machinery, the full leaf bags filled with fresh leaves from the tea picker should be promptly transferred to a cool and cool place to avoid the sun from prolonged exposure to cause deterioration of fresh leaves.
After the fresh leaves are picked, some of them are directly sent to the tea processing factory, and a full-time acceptance person at the tea factory accepts the acceptance of the fresh leaves, and then stores them in a unified manner. However, some tea plants and fresh leaves are weighed and accepted in the tea plantations. The proceeds, that is, directly to the tea plantation to purchase fresh leaves, and then returned to the tea plant for acceptance, should be in the acceptance process of fresh leaves, during transportation, do not directly contact the ground, so as to avoid contamination by the ground microbial, fresh leaves acceptance in the tea garden, fresh Leaf over the scale, acceptance should be located in shaded areas, avoid direct sunlight. Harvested fresh leaves that have been harvested by experience must be stored in breathable bamboo baskets. The size of the bamboo baskets must match the size of the container.
Third, the pollution-free green tea manual processing technology points First of all, should require the processing of handmade famous tea has a sanitary processing environment, processing sites should be relatively independent, and livestock barhouse, toilets, pits, etc. should have a certain safety distance to prevent odor pollution tea . Secondly, hand-made tea must have special processing rooms and must not be mixed with kitchens, living rooms, etc. The frying tea room requires good lighting and ventilation, and the roof and walls of the brush are clean and the floor is smooth and dust-free. The frying room should be large enough. In addition to the frying pan and related utensils, as well as the operating space for the frying staff, there should be enough fresh leaf area. The processing room is not allowed to enter and leave the people unrelated to the processing. It is also forbidden for children to enter and play casually to prevent the tea from being polluted. In the processing room, it is not allowed to stack articles that are not related to the processing of tea, and it is also forbidden to pile up articles that will cause the tea to be contaminated.
Non-pollution manual tea processing using fresh leaves due to the more tender, so more demanding picking requirements. We must emphasize the use of bamboo tea baskets to hold fresh leaves, and plastic utensils and other utensils that are prone to suffocating fresh leaves are not allowed. After the fresh leaves are harvested, they shall be promptly sent to the processing room to be cooled, to prevent fever and deterioration. The fresh leaves must be planted in the pot, and the fresh leaves cannot be directly distributed on the ground.
The stoves and utensils used for manual frying should be used exclusively. It is best to use a special frying pan that uses electricity, liquefied petroleum gas, etc. as a heat source. At present, some tea areas use charcoal as a kind of manual frying tea pot. It should be noted that when charcoal and ash are added, tea leaves should not be contaminated, and tea must not be cooked in a rice cooker. The bamboo baskets and baskets used are also used. Should be dedicated. At the end of the work day, the pans and utensils should be cleaned in time, and the tea pans should be fully maintained after the end of the tea season. After inspecting, repairing and replacing the electric heating wire and cleaning the pot wall, it shall be connected to the power supply to heat the frying pan and apply evenly a small amount of oil for making tea on the pot wall, and then cover it with plastic cloth. Keep it in a dry place to prevent the frying tea pot from rusting and affect the frying in the coming year. The oil used for making tea by hand is required to be colorless, odorless, and non-toxic. The tea brewed after wiping on the wall of the test pan does not produce oil.
Personnel who perform manual tea-frying should also have hygiene licenses issued by the health department. There should be special work clothes and caps when frying, and they should be taken off from the processing room and placed in the processing workshop. Washing, frying personnel should pay attention to personal hygiene. Source: Food Partner Network Information Officer: Provided by Heilongjiang Land Reclamation Bureau Economic Commission LH

Non-pollution green tea picking and processing
There are many kinds of tea in China, and the requirements for fresh leaves are different. For green tea, there are many factors involved in the determination of tea picking standards, but overall, mainly based on the requirements of tea processing on the tenderness and quality of fresh leaves, and considering the biological characteristics and yield of tea shoot growth. Factors are determined. The pollution-free green tea harvesting, transportation and manual processing technologies are now discussed as follows:
