Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of agricultural machinery equipment, and particularly relates to a fruit tree trimming device. BACKGROUND
[0002] Fruit tree trimming is not limited to pruning branches and leaves, but is a comprehensive management process, aiming to regulate the balance between growth and fruiting of fruit trees through a series of technical means, and to improve fruit quality and tree health. In addition to branch and leaf pruning, fruit tree trimming also includes branch pulling and stretching, bud carving, flower and fruit thinning, and young tree shaping, etc.
[0003] Bud carving is an important bud promoting technology in fruit tree management. Bud carving is to physically damage the phloem around the terminal bud or lateral bud to block the downward transport of auxin, release the inhibition of lateral buds, and promote new branches to grow from the carved part. Immediately applying healing agent after bud carving is a key technology in fruit tree cultivation. The two work together to significantly improve tree health and fruit yield. The mechanical damage caused by bud carving can damage the bark barrier and provide a pathway for pathogenic bacteria. Chitosan and polysaccharide substances in biological healing agent can form a protective film to isolate external microorganisms. Immediately applying chitosan healing agent after bud carving can effectively improve the germination rate of new branches. However, the process of bud carving and healing agent application is difficult to complete simultaneously, resulting in poor new branch germination effect after bud carving. SUMMARY
