High-yielding Kuding tea high-yielding cultivation techniques
Planting a garden 1. Garden choice: Choose a deep valley with sufficient water, deep soil, fertile gentle slopes or high humidity. 2. Garden planning: Reverse gradient steps shall be established according to the contour line above 15 degrees, and the width of the ladder shall not be less than 2.5 meters. Gradient of 15 degrees below the chessboard layout tea line, roads, ditch. Garden soil to be full, depth 40 cm or more. The plants are 2 meters apart and are spaced 1 to 1.5 meters apart. The tea rows are parallel and are arranged at the same height. The planting holes are arranged according to the character and the depth of the hole is 70-80 cm. The sidewalk in the park is 2 meters wide, and the farm road is 4-6 meters wide. Flood protection trenches, flood discharge trenches, and storage trenches are arranged vertically and horizontally in size. 3, Shizujifei: base fertilizer to livestock manure, compound fertilizer, soil miscellaneous fertilizer and other mixed piled up. Apply about 100 kilograms per hole and fill 15-20 centimeters of topsoil. The remaining 15 to 20 centimeters will be filled when it is planted. 4. Timely planting: Put the nursery stock that meets the nursery standard in the center of the hole, raise the seedling by hand, fill the soil with one hand, and fill it to the original soil surface. It is advisable to compact it slightly. Plant the grass around the plants and cover the grass in winter and spring to prevent cold. Cultivation and management 1. Soil conservation and moisturizing: long-term maintenance of soil moisture, grass can be planted in the park or planted green manure, leguminous crops, and eradicate weeds in time to keep the soil loose and not compacted. 2. Scientific Fertilization: The young trees are mainly tree growth, resistance to bad weather and prevention of pests and diseases. The ratio of nitrogen, phosphorus, and potassium is 1:1:1. Before each round of buds germinate, it is applied by infusion or ditching and open-pit spraying. It is applied 5-6 times a year and 40-50 kg per mu. The adult tree is mainly harvested with buds and leaves, and the proportion of nitrogen, phosphorus and potassium is 3:2:1. The method of application is the same as that of juvenile trees, and the amount can be appropriately increased. In addition, 1-2 times of comprehensive leaf nourishment fertilizer can be sprayed on each bud just after germination. 3, pest control: insect pests are mainly fleas, ants; disease mainly red spots, disease and other diseases. To prevent the main, comprehensive prevention and control, the use of biological pesticides. The pruning technique cuts off the main branches or lateral branches with strong growth potential, suppresses the apical dominance, stimulates the sprouting of the upper buds to form lateral branches, and quickly forms a structured tree structure. In addition to high-temperature and dry periods, pruning can be performed throughout the year. When the plants are 50 cm in height and the branches have been lignified or semi-lignified, the first pruning is performed 20-25 cm from the ground and the upper main branch is cut off. When the lateral branches grow to stem diameter 0.5 cm above, height 25 cm, the branches have been lignified or semi-lignified, in the last cut mouth increased 15-18 cm for a second trim, cut the upper main branch, after the trimming method So on and so forth. When a 3-4 layer skeleton is formed and the canopy surface exceeds 60 cm, the canopy can be cut with a flat cutter. After that, a light trimming can be performed once a year or every other year to smooth the canopy picking surface to stimulate sprouting of the axillary buds to increase the number of buds that can be picked. The number of leaves improves the quality of fresh leaves. Picking method adopts and combines, batches in batches, and repeats several times, picking according to the standard. The saplings are mainly raised, supplemented by mining; the production period is mainly mining and supplemented by farming. The long shoots are multi-picking, the short shoots are sparse, the tall shoots are low, the low shoots are high, the strong shoots are weak, and the crowns are leveled to keep the crowns balanced and flat. The tip of the tip of the leaf is not adopted, and the leaves are not opened. The tip of the leaf is usually 3-4 leaves, and leaves 1-2 leaves. China Agricultural Network Editor
