Technical Measures to Improve the Survival Rate of Clonal Superior Tea Seedlings in Cultivation

　　 The tea plantation area in Mangshi has reached 15.2 Ten thousand mu, area of high-quality clonal tea gardens 2.1 Ten thousand mu, accounting for the total area of tea gardens. 13.8% Within the province, this is a tea‑growing region with a relatively low rate of elite‑variety adoption. Compared with planting seedling‑grown tea, cultivating clonal elite varieties requires distinct cultivation and management practices; improper planting or inadequate care can adversely affect survival and orchard‑establishment rates. Therefore, when promoting the planting of clonal elite tea, it is essential to pay close attention to specific technical measures that help enhance both survival and establishment rates.
　　1 Ensure high-quality excavation by leveling and meticulously preparing the tea‑planting site: on flat ground, use a straight line to mark and dig planting trenches; on sloping terrain, construct contour terraces and lay out planting furrows with wide row spacing. 1.7 Rice, planting furrow depth 50 Centimeters, base width 60 Centimeters; return the topsoil to the furrows, cover with subsoil, and then level and refine the tea‑planting bed. The optimal time for digging is during the year of planting. 4 Completion before the end of the month will facilitate soil maturation, enhance soil water-holding capacity, and improve survival rates.
　　2 , Ensure the quality of seedlings. Do not plant weak, small, or substandard seedlings. Based on Mangshi’s climate, rainfall, and temperature conditions, different townships at varying altitudes exhibit distinct temperature and precipitation patterns: lower-altitude areas tend to be warmer—for example, Zhongshan Xiaojie, Chafang Huihei, and Xiangang Mangya all experience relatively high temperatures—, in 6-7 The monthly temperature reaches as high as 35-38C Weak and young seedlings have poor drought resistance and lower survival rates after planting; therefore, two-year-old seedlings or robust one-year-old seedlings grown in nursery bags are typically selected. Altitude 1500 In areas above a certain elevation, where temperatures are low, rainfall is abundant, and foggy conditions are frequent, tea seedlings have a high survival rate; even one-year-old robust seedlings are easy to establish, though the requirements for these can be somewhat relaxed.
　　3 When planting, strict quality control is essential. Given the characteristics of the fibrous root system of clonal superior tea seedlings, it is imperative to dig planting holes and set the seedlings at the proper depth—typically determined according to the length of the root system. 20 (centimeters deep), ensure stability and firmness, and avoid damaging the roots; choose favorable weather conditions for transplanting. Avoid transplanting on sunny or scorching days; overcast or light‑rain conditions are more suitable. Plant per mu… 2400-3200 Plants may be planted in single or double rows at a fixed spacing.
　　4 Strictly regulate soil moisture. Moisture is critical to the survival of tea seedlings; during the dry winter months, many tea gardens suffer seedling dieback due to insufficient water. For newly planted tea seedlings, apply plastic mulch or a layer of mountain grass to conserve soil moisture, enabling the seedlings to safely endure the dry winter—this is a key technical measure for improving the survival rate of cuttings.
　　5 Strengthen seedling management after setting the fixed values. ① After transplanting, seedlings must be carefully protected from trampling by cattle and horses and from damage caused by grubs and insects. Weeds should be removed frequently, and any pest or disease outbreaks should be promptly controlled. ② As the dry winter approaches, the rainy season is drawing to a close. 10-11 In this month, carry out shallow soil loosening and earthing-up; in principle, avoid disturbing the tea roots during loosening, and ensure the earthing-up is of an appropriate thickness. 10 About a few centimeters; ensure adequate soil moisture and help the tea seedlings survive the winter safely. ③ As the tea trees grow, regular formative pruning should be carried out annually and in stages to establish an optimal harvesting canopy; such pruning, especially when performed in the same year, also helps improve survival rates, thereby laying a solid foundation for high and stable yields. ④ Based on the tea plants’ growth vigor and age, fertilizers should be applied in multiple installments and at staggered intervals to boost both yield and quality, thereby cultivating high‑yielding, stable‑producing, pollution‑free, premium organic tea gardens as well as renowned, high‑quality tea estates.
