Different studies show that oolong tea can promote metabolism, burn fat and improve the absorption of dietary fat. It contains catechins and polyphenols that burn calories. Combining exercise with a balanced diet can promote weight loss.
2.

Introduction to Oolong Tea Oolong tea, also known as green tea and semi-fermented tea, is a unique tea in China. We can explain what oolong tea is through the tea-making process of oolong tea. Oolong tea is a kind of tea with good quality, which is made by the processes of deactivation, withering, carving, shaking, semi-fermentation and baking.
Oolong tea, as a representative of China tea, is a semi-fermented tea, which is characterized by transparent amber tea juice. In fact, oolong tea is just a general term, and it can be subdivided into many different kinds of tea. For example: Narcissus, Huang Dan (Huang Jingui), Benshan, Hairy Crab, Wuyi Rock Tea, Frozen Top Oolong, Cinnamon, Lan Qi, Lohan Aquilaria sinensis, Phoenix Abies, Phoenix Narcissus, Lingtou Abies, Color Ring Tone, Tieguanyin suitable for seafood, and so on.
How to manage early spring tea? 1. Weeding and loosening soil: After 4-5 months of rain and snow, the soil has hardened and some grass has grown. At this time, the soil temperature is low. Therefore, weeding and loosening soil before spring tea mining is beneficial to loosen soil, raise soil temperature, cut weeds, reduce water and nutrient consumption, and promote early germination of spring tea. Weeding is generally carried out at the end of February and the beginning of March, and the depth is 10- 15cm.
2. Application of germination accelerating fertilizer: The application time of germination accelerating fertilizer should be sooner rather than later. Ditching and applying at the place15-20cm away from the roots of tea trees, and applying 30-35kg urea or 30kg compound fertilizer or 2000-2500kg decomposed fertilizer per mu. After application, cover the soil. For tea gardens that can't be furrowed and fertilized, you can pee in rainy days, shake the tea shed with bamboo poles and let the fertilizer fall into the soil. Three. Pruning: Pruning should be carried out from the end of February to before pricking, and no later than March 10. Therefore, after a winter dormancy, the stems and roots of tea trees store more nutrients and can be easily restored after pruning. Coupled with the rising temperature in early spring, the pruned branches are not easy to freeze, and the labor force is not tight, so it is easy to master. Tea gardens generally advocate light pruning, that is, cutting off the autumn shoots (green stems) last year, retaining the spring and summer shoots (red stems) and cutting off about 2-3cm. If the crown is frozen, it should be trimmed according to the degree of freezing. Pruning should be shallow rather than deep, so as not to cut off some sprouting branches. For frozen tea gardens that do not harvest famous and excellent tea, pruning in spring can be changed to pruning after spring tea to harvest early spring tea.
Four. Anti-freezing: the climate is abnormal in early spring, and the temperature is warm and cold at first. This climatic condition is extremely unfavorable to the production of high-grade famous tea in tea gardens. We should always pay attention to the local weather forecast in early spring and take measures to prevent colds in late spring. After the release of cold wave forecast, for tea gardens with early budding leaves, it is necessary to concentrate manpower on harvesting young leaves to reduce freezing damage losses. In tea gardens on windward slopes prone to freezing, cover the tea shed with straw, weeds or sunshade nets, and remove the cover in time after the cold wave. After the tea tree is damaged by freezing, corresponding nursing and rejuvenation measures must be taken according to the freezing situation, so that the tea tree can recover its tree vigor as soon as possible.
Verb (abbreviation of verb) Clear ditch and drain water: There is much rain in spring. If the drainage of tea garden is not smooth, tea trees are vulnerable to waterlogging and root rot, which leads to delayed tea buds and reduced yield. Therefore, it is necessary to ditch and drain in time and dredge the drainage ditch to ensure that the groundwater level is below 1m, so that when the rain stops, the tea garden will dry up and there will be no water.
Supplementing foliar fertilizer with intransitive verbs: In early March, when the temperature exceeds 12℃, the absorption function of tea can be used to supplement fertilizer outside the roots, so as to promote the early germination of tea trees, increase yield and improve quality. In vitro fertilization can be carried out with 0.5% urea, 0.3% potassium dihydrogen phosphate, multifunctional nutrient solution "Zhongchazao" and hormone "920".
