An Experiment on the Suitability of 10 Tea Cultivars(Lines)for Mechanical Harvesting in Shaoxing Rigion
摘要
Abstract
To identify tea cultivars suitable for mechanical harvesting and the key influencing factors,this study sys-tematically determined and analyzed relevant indicators for 10 tea cultivars(lines)at the tea experimental base of Shaoxing Academy of Agricultural Sciences Over three consecutive spring seasons from 2023 to 2025.The mea-sured indicators included phenological periods,shoot density and composition before mechanical harvesting,mor-phological characteristics of new shoots,yield of mechanically harvested fresh leaves,and composition of harvest-ed shoots.The results indicate that the tea line CT2007-0001 exhibited the highest shoot integrity rate and yield,making it the most suitable cultivar(line)for mechanical harvesting.Correlation analysis of key indicators further reveals a significant and positive correlation between shoot density and yield,which is the most critical factor affect-ing yield.The length of the basal stem of the three-leaf-and-a-bud shoots showed a strong positive correlation with shoot integrity rate,while the length of the three-leaf-and-a-bud shoot and the length of the lowest internode of the three-leaf-and-a-bud shoot exhibited moderate positive correlations with shoot integrity rate.The length of the basal stem of the two-leaf-and-a-bud shoot also demonstrated a moderate positive correlation with shoot integrity rate.By contrast,the leaf insertion angles of the lowest leaves on two-leaf-and-a-bud and three-leaf-and-a-bud shoots showed slight negative correlations with shoot integrity rate.The findings of this study provided valuable insights for breeding tea cultivars suitable for high-quality mechanical harvesting,thereby promoting the comprehensive mechanization of the tea industry.关键词
