Embodiment Construction

[0011] A cultivation method for accelerating the growth of red beech and improving the ornamental traits of leaf color: specifically selection, or through thinning, the canopy density in the red beech forest is not higher than 80%, so that the red beech forest is ventilated and light-transmitting. According to the size of the red beech plant, from March to July every year, according to the size of the seedlings, urea should be topdressed appropriately, and it is advisable to apply it in holes. In mid-August, it is advisable to ring the bark of the main branches of the red beech for 1 / 2 to 3 / 4 circle, and the depth of the ring injury should not damage the xylem. In mid-September, the leaves were sprayed once with a mixture of "0.5% potassium dihydrogen phosphate + 3% sucrose + 2% hydrogen peroxide" to promote the formation of leaf color substances. This method can increase the growth of red beech by more than 8%, promote the color of red beech leaves to purple red or red, and a...

Abstract

The invention relates to a cultivation method capable of accelerating growth of red beech and improving ornamental traits of leaf color. The method comprises the specific steps: carrying out intermediate felling to enable forest crown density of the red beech not to be higher than 80%, and carrying out urea dressing by 20g to 180g monthly on each of red beech plants, of which the ground diameter is 2.0cm to 18.0cm, in March to July according to tree body sizes; in the middle ten days of August, subjecting 1/2ring-to-3/4ring of each main branch bark to annular injury at the annular injury depthof 0.2cm to 0.3cm; and in the middle ten days of September, subjecting a mixed solution of 0.5% potassium dihydrogen phosphate, 3% saccharose and 2% hydrogen peroxide to leaf spraying once, so as topromote formation of leaf color substances. According to the method, the growth of the red beech can be improved by 8% or more, the change of a leaf color of the red beech into purplish red or red ispromoted, a leaf color change stage is advanced by 7 to 10 days, and the improvement of an economic value of the red beech and the ornamental traits of leaves is facilitated.

Description

technical field [0001] The invention relates to a cultivation method for accelerating the growth of red beech and improving the ornamental traits of leaf color, in particular to a method for accelerating the growth of red beech and improving the ornamental value of its leaf color, which is a method for advancing the period of color change of red beech leaves , which can meet the needs of tourists for leaf viewing in autumn and winter. Background technique [0002] Red beech is a deciduous tree of Ulmaceae. Its bark is iron-blue, and its mature leaves are reddish to deep red. It is an important tree species with both timber and ecological landscape. In recent years, due to the decline in the nursery stock market, the cultivation of tree species with both ecological landscape and materials has attracted the attention of the industry. For example, some departments are eager to find alternative varieties of poplar: the "red beech to replace poplar" is being implemented in areas ...
