Non-pollution Tea Tree Cultivation Management

First, the cultivation and management of young tea gardens 1. Deep plowing to improve soil. Water is an important component of tea plant organisms. Deeply ploughing and improving soil can store water and water, ensuring that the roots of tea plants grow well. When deep plowing, the topsoil and heart and soil should not be disturbed and placed on the inner and outer ditch respectively. The depth of deep plowing needs to be more than 50 cm. 2, transplanting. Transplanting time depends on the species, usually in late spring from late February to mid-March, or from late fall to early winter, from mid-October to early November, and it is better to choose cloudy or rainy weather for transplanting. The weather in the northwest winds or the rainy weather is transplanted. Using a single-row planting method, the line (bush) distance was 1.5 to 0.33 meters, and more than 4000 strains per acre were used (3 strains were bundles). Planting ditch with 400 kg of manure cake per mu and decomposed livestock manure 2000-4000 kg. Seedlings should be selected 1 to 2 seedlings, watering 1 to 2 days before the seedlings permeable, so that the seedbed soil is moist, in order to reduce the root system damage. When the seedlings are lifted, the roots should be soiled, transplanted with soil, appropriate deep-rooted (submerged at the root neck), non-exposed fibrous roots, stretched roots, appropriate compaction, pouring root water, cover the loose soil at the base, and cover the grass. 3, seedling period management. Diligent grass, diligent irrigation, thin fertilizer, timely control of pests and diseases, in order to achieve seedling protection, seedlings and strong seedlings. Young tea gardens should be artificially grassed, banned from chemical pesticides, and weeding should be done 4 times a year. For perennial tea seedlings, as far as possible, weeding should be done first within 30 cm of the seedlings to prevent loosening of tea seedlings, affecting growth, and then proceeding between rows. Scribbled grass. 4, shaping pruning. It is mainly to inhibit the tea tree apical dominance, promote the growth of branches, increase the number of branches and branches, and to form a plump canopy. This is one of the basic measures for the cultivation of high quality and high yield tea plants. Young tea trees must be pruned three times. Different varieties have different growth habits, so pruning techniques are also different. The main branch was cut from the ground at the first 20 centimeters for the first time; the second branch was cultured in the second time. When the height of the tree exceeds 35 centimeters, the mouth was cut 30 to 35 centimeters from the ground; the third time, a high-yield crown skeleton was formed, and the height was trimmed. The second trimming is based on the increase of 15 cm, requires cutting, cutting off the weak branches and pests and branches. Second, after the production of cultivation management 1, according to the quantitative production, scientific fertilization. Promote the use of organic fertilizers and balanced fertilization methods, prohibit the use of chemical fertilizers, municipal waste, etc., apply organic compound fertilizers. Generally, 100 kg of dry tea is collected and 12 to 15 kg of pure N fertilizer, 4 to 5 kg of pure P fertilizer, and 4 to 5 kg of pure K fertilizer are used. The amount of organic fertilizer is converted into elemental fertilizer. To reuse basal fertiliser, generally every 100 kilograms of dried tea will be applied with manure, compost, 1,000 kilograms of manure, or 90 to 120 kilograms of cake fertilizer. During the period from August to October, the soil will be excavated under a trench. Fertilizer is applied one month before tea-picking, mainly based on decomposed manure, biogas slurry and other fast-acting organic fertilizers. 2, light trimming time. Change the conventional spring tea before the light pruning time: 1 light tea before summer pruning, that is, after taking the spring tea light pruning, the spring tea moderately early end, seize the time for light pruning, otherwise, a large number of summer tea has germinated, affecting summer tea Yield, trimmed to mildly flattened. 2 After the autumn tea light pruning, can be lightly trimmed in autumn in October after the autumn tea, the spring tea can be earlier to germinate the following year, open the park earlier, the degree of trimming to mild flat cut is appropriate.
