TECHNICAL FIELD
[0001] The utility model belongs to the technical field of orchard, specifically a kind of fruit tree ring pressure device. BACKGROUND
[0002] Girdling is an auxiliary technical measure commonly used in fruit tree cultivation and management, aiming to adjust the growth rhythm of fruit trees and promote the quality and yield of fruits. In some cases, girdling the bark is necessary, especially for jujube trees, persimmon trees, citrus trees and hawthorn trees. Girdling has a long history in fruit trees, and the method is simple, labor-saving and efficient. However, girdling is a man-made injury to the tree, and it is also a highly technical work. If not handled properly, excessive girdling and wide girdling can lead to leaf loss, branch death, tree death and early decline of tree vigor. The most direct impact of girdling on the tree is physical damage to the tree, which increases the risk of insect and pathogen invasion into the tree.
[0003] To reduce the negative effects of girdling and maintain its advantages, some orchard producers and scholars have improved girdling, such as using straps, iron wires and electric heating rings to girdle and electrically heat girdling without damage, in order to achieve the purpose of low damage or no damage to the tree. Non-invasive physical measures such as girdling without damage belong to the category of non-invasive physical measures, which use physical materials to compress the tree and remove the force materials after fruit harvesting, thereby restoring the phloem transport function. However, the existing girdling device generally uses full-circle girdling, which causes greater damage to the fruit tree, and in the later stage, the girdling device is wrapped inside due to the rapid growth of the fruit tree, making it difficult to remove the girdling device without damage.
