| Abstract: |
| 【Objective】The key technologies of mechanical picking in mature Yinghong No. 9 tea garden were studied in order to provide scientific basis and technical references for the implementation of mechanical picking in Yinghong NO. 9 tea garden in Guangdong Province.【Method】The present study investigated the key technologies of mechanical picking in Yinghong No. 9 tea garden in terms of pruning and remaining, picking period, picking standard and fertilization management.【Result】The results showed that the tea garden management techniques of mechanical picking suitable for the mature Yinghong NO. 9 were: adjusting the density of sprouts by heavy pruning （40-50 cm above the ground） in winter and applying organic fertilizer, chemical fertilizer and compound fertilizer after one tea season, picking tea leaves when one shoot and two leaves reached about 60%-70%, and mechanical picking with cutting depth of 4-5 cm for spring tea, while with cutting depth of 5-8 cm for summer and autumn tea.【Conclusion】Mechanical picking is suitable for Yinghong NO. 9 due to its wide leaf angle and long internodes. By using appropriate pruning and retention, fertilization management, picking period and picking standard and other key technologies, the mechanical picking can be realized Yinghong NO. 9 tea garden. |
