Mechanical tea picking is a new tea picking technology and a systematic agricultural project. It is a concrete manifestation of modern agriculture. Tea garden cultivation and management are the foundation, tea plucking machines are the key, and operation and use technology is the fundamental guarantee for improving the efficiency of tea gardens.

There are 5 key points for mechanical tea picking:

1. Pick at the right time to ensure the quality of fresh tea

Tea can sprout four or five new shoots every year. In the case of manual picking, each picking period lasts for 15-20 days. Tea farms or professional households with insufficient labor often experience excessive picking, which reduces the yield and quality of tea. The tea harvester machine is fast, the picking period is short, the number of picking batches is small, and it is cut again and again, so that the fresh tea leaves have the characteristics of small mechanical damage, good freshness, fewer single leaves, and more intact leaves, ensuring the quality of the fresh tea leaves.

2. Improve efficiency to increase revenue and reduce expenditure

Mechanical tea picking can be adapted to the picking of various types of tea leaves, such as black tea, green tea, and dark tea. Under normal circumstances, the tea harvesting can pick 0.13 hectares/h, which is 4-6 times the speed of manual tea picking. In a tea garden with a dry tea output of 3000 kg/ha, mechanical tea picking can save 915 workers/ha than manual tea picking. , thereby reducing the cost of tea picking and improving the economic benefits of tea gardens.

3. Increase unit yield and reduce missed mining

Whether mechanical tea picking has an impact on tea yield is a matter of great concern to tea technicians. Through a comparison of 133.3 hectares of machine-picked tea gardens over four years and a research report from the Tea Research Institute of the Chinese Academy of Sciences, we know that the tea yield of general machine-picked tea can be increased by about 15%, and the yield increase of large-area machine-picked tea gardens will be even greater. High, while mechanical tea picking can overcome the phenomenon of missed picking.

4. Requirements for mechanical tea picking operations

Each Two Men Tea harvesting machine needs to be equipped with 3-4 people. The main hand faces the machine and works backward; the auxiliary hand faces the main hand. There is an angle of about 30 degrees between the tea picking machine and the tea shop. The cutting direction during picking is perpendicular to the growth direction of the tea buds, and the cutting height is controlled according to the retention requirements. Generally, the picking surface is increased by 1-cm from the last picking surface. Each row of tea is picked back and forth once or twice. The picking height is consistent and the left and right picking surfaces are neat to prevent the top of the crown from being heavy.
