At the same time, the area with adequate water resources and convenient transportation should also be considered. (2) The planning and layout of the garden should be reasonable, so that tea gardens can be landscaped, water-conserved, and convenient to walk, and the cultivation and cultivation should be scientific. At the same time, attention should be paid to protecting the ecological environment and preventing soil erosion. (3) Mountainous land reclamation, first opening the road, opening the platform, taking heart and soil to fight, topsoil back to the ditch, and opening up from the bottom to the top, requiring the same level of each section of the ladder, the outside height of the ladder surface, the width of the ladder surface is not less than 2 meters, and to do before there is a bamboo section after the ditch, planting ditch depth of 6060 cm, the next foot base fertilizer and mix. 3. How to increase the survival rate of Xinzhi Tea Garden? (1) Seedlings and seedlings: selection of seedlings for the first year of autumn and winter cuttings requires seedling heights of 20 cm or more, diameters of roots at 0.25 cm or more, and seedlings that are free of pests and diseases, with no less than 6 leaves. (2) Science raises the seedlings: 1-2 days before raising seedlings, water should be used to permeate the seedlings, and then after draining, when raising the seedlings, use a hoe to dig, protect the root system from damage as much as possible, and at the same time, remove heterogenic strains and diseased strains. (3) Planting time: The tea planting time was selected in autumn and winter and early spring, that is, from late October to February. Generally, except for the colder tea areas, planting and transplanting should be carried out in the fall and winter seasons, and the plants should be planted after rain or on cloudy days. (4) Planting: Before planting seedlings, first use yellow mud to dip the roots. Colonization was arranged with double rows or double rows. The spacing between the rows is 3030cm, two per hole, and the distance between the plants is about 6cm. When planting, let the tea roots naturally stretch, and then cover the soil compactly and firmly, water, and finally cover a layer of loose soil to maintain the shallow ditch of 10-15cm. And covered with straw, etc. 4. How to do the drought-freezing work of young tea gardens?

You can use thatch, leaves, straw, straw and other materials; before the cold-frost frost comes, cultivate soil about 10cm in the rhizome of the tea tree. In the spring of the second year, you can open it again and cover the tea room. Grass thickness should be more than 10cm. Can also be used to cover the conditions of the film, especially young seedlings tea seedlings have a certain role.

Generally, the plough depth is 10-15cm, and it is carried out two to four times a year. For deep plowing, young tea gardens that have not been fully inverted prior to planting should be fully ploughed within 2-3 years, typically 20-30 cm deep and combined with organic fertilizer. 5. How to fertilize young tea plantations? The time of topdressing and the amount of fertilizer used in young tea gardens depend on the age of seedlings. Generally, the first-year tea plant uses about 5kg of standard nitrogen fertilizer per year before spring tea or once after spring tea; second-year tea plants apply about 10kg of standard nitrogen fertilizer throughout the year. 60% before Spring Tea and 40% after Spring Tea; 3 and 4 in-year tea trees apply about 15kg of standard nitrogen per mu, which can be applied before spring tea, after spring tea, and after summer tea, 50%, 30% and 20 respectively. %; For the fifth and sixth instar tea trees, about 20 kg of pure nitrogen is used for each 100 kg of dry tea produced after the production. 6. How to make young tea tree styling pruning? After the first year of tea planting, it can be shaped and trimmed. Generally, one year will be cut once. The saplings will grow well and can adopt the three-pronged three-pronged cutting method for two years.

Mining side. 7. How to make scientific and rational fertilization for mining tea plantations? Tea garden fertilization should promote "a base", "three recovery", "multi-spray" method. "One base", that is, in the mid-October to early November of each year when the tea tree grows dormant, a 20-30 cm deep fertilization ditch is opened vertically below the teacup, which can also be combined with the autumn and winter tea plantation to deepen the furrow and fertilize. The annual amount of fertilizer is 40-50% of nitrogen fertilizer and total phosphorus and potassium fertilizer. Fertilizer is mainly organic fertilizer, such as cake fertilizer, pig cattle fertilizer, heap fertilizer, human waste, tea special fertilizer, etc., with the application of phosphorus and potassium fertilizers. “Three recoveryâ€: one month before the spring tea extraction, 15-20 days after picking the spring tea and 15-20 days before picking the autumn tea, topdressing the quick-acting chemical fertilizers respectively, and the pre-emergent fertilizer amount of the spring tea accounts for about 3 total application rates of the top dressing. 40-50% of the rest, the remaining summer and autumn tea accounted for about 25% of the top dressing. “Multi-sprayâ€: In the growing season of tea trees, chemical fertilizers are used as the root-spraying fertilizer.
