The meaning of reasonable tea picking refers to the use of picking techniques to promote the vegetative growth of tea trees under certain environmental conditions, control the reproductive growth, and coordinate the contradiction between picking and raising, quantity and quality.
The meaning of reasonable tea picking means that under certain environmental conditions, picking techniques are used to promote the vegetative growth of tea trees, control reproductive growth, and coordinate the contradiction between picking and nourishing, quantity and quality, so as to achieve more tea picking and good picking. Tea, to improve the economic benefits of tea. The main technical content of tea machinery can be summarized as "standard harvesting, timely harvesting, batch harvesting, and leaf-leaving harvesting".
Standard picking refers to picking new shoots of tea trees according to a certain amount and tenderness standard. The quality of the finished tea is mainly determined by the quality of the raw materials of the fresh leaves, besides being influenced by the processing technology. Generally speaking, when picking delicate buds and leaves, the content of tea polyphenols, caffeine, amino acids, catechins, etc. is high, and the internal quality is good, but the weight is low, and the yield is low; and the old and coarse buds, polysaccharides, crude fibers, etc. High content, heavy weight, high yield, but low active ingredient content, poor internal quality. In other words, the level of tea production, the quality of the tea, and the amount of income are determined to some extent by the picking standards. Therefore, in production practice, it is very important to reasonably formulate and strictly grasp the picking standards. There are many types of tea in China, with different quality specifications and different picking standards, which can be classified into four categories.
According to the growth and development of the new shoots and the picking standards, the tea leaves are picked off the tree in time. In agricultural production, it is an important principle not to violate agricultural time. The production of tea with leaves is more obvious in seasonality. It is generally considered that the mining period should be early and not later, and it is better to be earlier, especially spring tea. At this time, the tea tree has abundant storage materials, mild climate, superior temperature and humidity conditions, strong tea tree sprout, strong growth of new shoots, and peak seasons. If the mining period is not properly grasped, it is easy to lose sight of one another. Raising and harvesting the old will not only make the quality of the tea poor, reduce the yield, but also affect the tree vigor and increase the production of tea throughout the year.
