折断式采茶机采摘效果及应用分析OA

To investigate the plucking performance of the snap-type tea plucking machine,this study compared the picking efficiency and fresh leaf quality of three picking methods:manual picking,breaking-type picking and recip-rocating cutting.The fresh leaves obtained by the three methods were processed into flat green teas,Gouqing,and Maofeng,respectively,for sensory quality evaluation and catechin component content detection.The results show that the order of the mechanical integrity of buds and leaves from high to low was manual picking,breaking-type picking and reciprocating cutting.Reciprocating cutting had the highest picking efficiency(46.06 kg/h),which was 2.68 times and 15.56 times higher than breaking-type picking and manual picking,respectively.However,the fresh leaf yield was poor.In terms of sensory quality,among the same type of green tea,the quality of tea samples picked by breaking-type method was slightly lower than that by traditional manual picking,but significantly higher than that by reciprocating cutting.There was no significant difference in the contents of non-ester catechins in tea sam-ples under the three picking methods.There was no significant difference in the contents of ester catechins between manual and breaking-type picked tea samples,but both were significantly different from those picked by reciprocat-ing cutting.A cost-benefit analysis shows that breaking-type picking balanced efficiency and quality,had the opti-mal input-output ratio,and offered significantly greater economic benefits than the other two methods.The research results provided a theoretical basis for the mechanized picking and processing of high-quality tea.
