Abstract:

With the gradual expansion of the scale of Lycium barbarum cultivation as well as labor costs continue to increase, the realization of mechanization and intelligent harvesting of Lycium barbarum has become an important means to enhance the efficiency of Lycium barbarum production, but also to promote the quality of the Lycium barbarum industry, an effective way to develop. Based on the literature analysis method, this study combs and reviews the research progress of theory and equipment related to Lycium barbarum harvesting at home and abroad in the past 10 years, and further explores the future research direction and development trend of the existing research by analyzing the strengths and weaknesses of the existing research in theory and practical application. At present, the research on harvesting of Lycium barbarum is dominated by relevant domestic agricultural and forestry colleges and universities, and mostly take Ningxia region Lycium barbarum varieties as the object of research, the harvesting equipment is divided into portable and self-propelled, and its working mode includes vibration type, comb and brush type, pneumatic type and shear type, and the vibration type of harvesting efficiency is relatively ideal. In order to further realize the goal of efficient and low-loss harvesting of Lycium barbarum, the future research direction of Lycium barbarum harvesting related technology is proposed: 1) Combined with the differences in biomechanical properties of Lycium barbarum, strengthen the basic theoretical research, reveal the coupling and interactions mechanism between various parts in the harvesting process, and avoid the damage to the fruits in the process of mechanical operation. 2) Research and development of new agronomic techniques suitable for the operation of Lycium barbarum harvesting equipment, the deep integration of agricultural machinery and agronomy, to improve the overall harvesting efficiency. 3) Carry out the research of rapid identification and localization algorithm in complex field environment for Lycium barbarum fruit in irregular movement state, and identify and detect the maturity of Lycium barbarum fruit based on graph fusion technology. 4) Development of large-scale Lycium barbarum harvesting equipment based on automatic navigation technology and intelligent obstacle avoidance system.
