Wintering Management Technology of Tieguanyin Young Tea Garden
In recent years, Tieguanyin finished tea has been sold on the market, and prices have risen. The development of Tieguanyin Misheng Tea Garden has yielded quick results and high benefits. However, Tie Guan Yin is not well-planted, especially the youngest tea management requirements are the most stringent. The following will explain the main points of wintering in young tea gardens. First, the cultivation characteristics 1. Tieguanyin root is underdeveloped, the roots are not easy to heal after injury, drought resistance, poor cold resistance. Its fibrous roots are few, and its lateral distribution is large and its longitudinal distribution is not deep. Weeding and ploughing are too deep and too easy to damage the root system and cause dead seedlings. When planting, the soil is not compacted or the rooting water is insufficient, or the soil is exposed to high temperature and drought after planting. 2. Tieguanyin has a strong top edge. To promote the branching in time, grow more new shoots in order to increase production. 3. Tieguanyin has many buds and many results. A large number of flowers and nuts will consume nutrients and must be removed in time. 4. Poor adaptability. Tieguanyin has high soil requirements. Only in the thick soil layer of viscoelastic soil, Tieguanyin can grow well and has good quality. Second, management measures 1. Cover drought protection seedlings. The newly planted tea seedlings are poor in stress resistance and are afraid of dryness and fear of drying. The straw can be used to cover the whole garden, with a thickness of 5 cm; or covered with mushroom soil, which can reduce the soil surface temperature, maintain soil moisture, inhibit weed growth, increase soil organic matter, and improve soil physical and chemical properties. At the same time do a good job of moisture management to meet the tea tree's demand for water. 2. Make up the seedlings in time. The survival rate of Tieguanyin is relatively low. It is necessary to do a good job of checking seedlings to make up seedlings, leaving 2 strains per hole. 3. Thinning and thinning fruit. When buds emerge from tea, they must be removed in time to reduce nutrient consumption. 4. Reasonable fertilization. Before applying planting base fertilizer, apply 4-5 additional fertilizers per year. Apply each time the sprouts germinate. Apply 5-10 kg of compound fertilizer, 3-5 kg ​​of urea, and dig furrows 15 cm away from the roots. Dig a hole and cover it. Insufficient base fertilizer should be combined with organic fertilizer and chemical fertilizer application. Every year in winter, combined with shallow ploughing and applying base fertilizer, Mushi Fertilizer 1000 kg. 5. Weeding and weeding. Tieguanyin has a shallow root distribution. To avoid injuring the roots, artificial weeding can be used to cover the weeds on the side of the tea seedlings. At the same time, it can not always be plowed. In the winter, combined with the base fertilizer, a shallow medium tillage weeding can be performed. 6. Prune trim. The use of a cut-down cutting type is to cut the upper part of the stem 20 cm high before the tea planting. After the spring tea grows out, the top shoot and the longer side shoot that are more than 25 cm away from the soil surface are collected, and after the new shoots are sprouted in each round, the height is increased by 5-8 cm in the original foundation for topping. The canopy can be increased by about 20-25 cm throughout the year.
Plant extract is a product formed from plants as raw materials, through physical and chemical extraction and separation process according to the needs of the use of the final product extracted, to obtain and concentrate one or more active components in plants in a directional way, without changing the structure of the active components.
Proportional extract is the extract, liquid extract or powder made by the extraction and concentration of raw materials such as plants and animals. The number of raw materials before extraction and the mathematical ratio of the product after extraction and concentration generally do not have very clear composition and content.
1. According to the content of active ingredients, it can be divided into three types: effective monomer extract, standard extract and ratio extract;
2. Divided into glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc.
3. According to the product form, it can be divided into vegetable oil, extract, powder, lens, etc.
4. According to their use, plant extracts can be divided into natural pigment products, traditional Chinese medicine extracts, extract products and concentrated products.
