Pruning method for improving wind resistance of trees

Abstract

The invention discloses a pruning method for improving wind resistance of trees, which comprises the following steps of: S1, performing laser scanning on the trees by a laser scanner on a pruning machine, and displaying a 3D model of the trees on a computer terminal; s2, measuring the planting distance between adjacent trees, and measuring the wind direction and the wind speed borne by the trees, and S3, calculating the wind force borne by the trees according to the data analyzed in the S2 in combination with the wind force and wind field model of the region, and calculating the pruning amount required by tree crowns according to actual requirements. S4, simulation pruning is conducted on the 3D model of the tree at the computer end, and finally the optimal pruning scheme is obtained by integrating the wind resistance, the landscape performance and the like of the tree; s5, the optimal pruning scheme is transmitted to a pruning machine, and the pruning machine is used for automatically pruning the trees according to the optimal scheme. Automatic scanning and automatic trimming can be integrated, the trimming efficiency can be effectively improved, and meanwhile the wind resistance of trimmed trees can be improved.

Description

technical field [0001] The invention relates to the technical field of tree pruning, in particular to a pruning method for improving the wind resistance performance of trees. Background technique [0002] Pruning is an indispensable maintenance topic for street trees. Proper and timely pruning can not only correct and repair tree defects, form a good tree mechanical structure, promote the healthy growth of trees, but also greatly improve the wind resistance of trees, improve Public safety, ensuring the safety of citizens' lives and property. [0003] Before the typhoon comes, tree pruning should also have the following technical points: [0004] Tree pruning should give priority to the branches and leaves of the following problems: bad branches (such as small-leaved banyan tree and other vigorous growth, allowing bad branches to grow, will easily cause root-to-shoot ratio imbalance, top-heavy, typhoon weather is easy to fall, and the aesthetic effect is greatly reduced), no...

Problems solved by technology

[0008] Unless there is a serious risk to the tree, the tree should not be "skinned" as it will be difficult to grow back after the tree has been completely removed and may even cause the tree to die

[0009] However, the existing tree pruning is all manual and based on experience. It cannot be combined with different environments in different regions to achieve optimal pruning of trees. In this way, the overall wind resistance of the pruned trees cannot be improved. Effective improvement cannot resist strong winds, and most of the existing tree pruning uses cutting discs or cutting saw blades to cut the branches and leaves of trees into uniform shapes. Although such pruning is efficient, it has no effect on the overall wind resistance. Obvious improvement, and most of the existing mechanical pruning is to take out the external branches and leaves, and cannot prune the internal branches and leaves, forming a cavity to improve wind resistance
