Zelkova serrata longitudinally-cutting thickening cultivating method

Abstract

The invention discloses a zelkova serrata longitudinally-cutting thickening cultivating method. The zelkova serrata longitudinally-cutting thickening cultivating method comprises the following steps that firstly, the method is carried out when the diameter at the breast height of the zelkova serrata ranges from 4 cm to 5 cm; secondly, the longitudinal cutting time is selected at the time when the zelkova serrata begins to bud at the end of March and at the beginning of April, the number of times of longitudinal cutting does not exceed six, and namely, longitudinal cutting is carried out one time each year and cannot be carried out more than continuous six years; thirdly, according to the longitudinal cutting method, a sharp cutter is used for longitudinally cutting the live bark of the trunk of the zelkova serrata into the xylem; fourthly, the longitudinal cutting heights need to conform to requirements; fifthly, three longitudinal cutting channels are formed during the first three years, and four longitudinal cutting channels are formed during the later three years; sixthly, inner bent parts are straightened; seventhly, appropriate fertilizing and cultivating are carried out on the longitudinal hurt parts. The scientific longitudinal cutting method is adopted to longitudinally hurt the trunk of the zelkova serrata, the sclerenchyma cell rings are broken, the internal pressure is weakened, and the young zelkova serrata can grow with the trunk thickened.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating beech trees through longitudinal injury and thickening. Background technique [0002] Beech is widely distributed in China. It grows slowly and has excellent materials. It is a precious hard-leaved broad-leaved tree species. Beech has strong adaptability, strong wind resistance, and smoke resistance. It is a good tree species for urban and rural greening and windbreak forests. [0003] Because the bark of beech tree is smooth and has no longitudinal cracks, the young trunk grows slowly, and the dissection of the young beech trunk shows that there are several layers of continuous and partially spaced stone cells outside the phloem, forming a circle with 4 to 5 layers Or 7-8 layers of sclerenchyma cells hinder the meristemization of the cambium, thereby affecting the thickening and growth of the trunk diameter, resulting in slow growth...
