The cultivation technique of white bud Qilan tea
Tea tree is a perennial crop. The construction of a new tea garden is the basis of tea production. As long as it is well grown, it can achieve long-term economic benefits. Therefore, we must conscientiously do a good job of quality, start with the basic work, and seriously choose the land and open the park in order to achieve long-term high yield and quality. The growth and development of the white bud Qilan is a unity with the external environment. The relationship between the quality of the garden and the quality is extremely close. Therefore, when choosing a garden, it is important to measure whether the climate, soil, water quality, topography and other conditions are suitable for cultivation. According to the characteristics of white bud Qilan tea, the soil layer should be thick (more than 1 meter), and the soil should be fertile (pH is 4.5-6.5) Red-yellow loam and water sources are sufficient, slopes are generally below 30 degrees, and altitude and altitude are between 500-1000 meters in mountainous and hilly areas. The planting quality is better, and the tea gardens should be contiguous. After the selection, it should be planned to open, flat and gently slope, the terrain is relatively flat and easy to develop, and the tea gardens on the slopes should be opened into tea gardens with horizontal ladders. The ladder walls must be first built, and the ladders must be rearranged. In case of a row of tea trees, the width of the ladder is about 2 meters, the steepest slope, and the surface of the ladder is not less than 1.5 meters. After digging the planting ditch, buried 30-50 lbs of weeds, garbage, and miscellaneous manure, and 100 kg of calcium, magnesium and phosphorus were planted in the ditch. Then, the topsoil was returned to the ditch for leveling. The key to the cultivation of white bud Qilan tea is how to increase the survival rate and ensure high yield in the future. Therefore, it is necessary to grasp the work of selecting the seedlings, selecting the best time and method for planting, rational planting and management after planting. 1 Selection of seedlings: It is necessary to use tea plants with a strong growth and development, root development, no pests and diseases, no contaminants, and a seedling age of more than 2 years, and a seedling height of 25 cm or more. 2 Planting time and method of colonization: The white bud Qilan tea is suitable for planting before and after the frost fall in areas with early spring 1-2 months or awns and sufficient water supply. Transplanting should be carried out with the soil when transplanting. With soil, before the planting, the tea should be cut and fixed 15-20cm high. When planting, the 15cm deep burrows should be dug (or handcuffed), the tea plants should be straightened, and the roots should be straightened. After that, the layers should be returned to the soil. The layer is tight and compact, and after the soil has been immersed for more than half of the time, the planting water is poured. After the water is infiltrated, continue adding it until it is level with the mud gate. 3 Proper and close planting: Plants are planted in single rows with a large row spacing of 1.2-1.4 meters, a plant spacing of 0.3 meters and a small distance of 0.3-0.35 meters. 3000-3500 plants per acre are appropriate. 4 Post-planting management: After the planting, it is necessary to make good nursing work for young teas: Do drought protection, freeze-proofing, supplementing seedlings, rational fertilization, regular pruning, light mining, and pest control. To do the above four tasks well, the high survival rate of tea leaves will lay a solid foundation for future tea production.
