Problems solved by technology

[0004] This situation is mainly due to the change of climate after the introduction of the plant, which greatly weakens the apical dominance of the plant's growth point, causing the growth of the side buds to exceed the growth of the main shoot, resulting in growth retardation

Embodiment 1

[0025] Example 1 A method for arborizing multiflora ash

[0026] 1) Transplant the buds of the last summer into a beautiful planting bag every spring; do not plant too deep, and ask the plants not to be skewed when planting.

[0027] 2) When the bud grafted plants sprout in the first year after grafting, there will be 2 to 4 new buds. The buds that are sent out leave a strong branch, and the remaining branches are removed to avoid dispersion and excessive nutrients;

[0028] 3) Before sprouting in the second year, all side branches on the main shoots should be trimmed, and the annual height of the main shoots will be measured at the end of the year;

[0029] 4) When the main shoot germinates, 4 side shoots will grow around the main shoot at the same time, remove the 4 side shoots beside the main shoot, and measure the growth of the main shoot at the end of the year;

[0030] 5) Before the shoots stop growing, the new side buds of the current year are completely removed, and the annual g...

[0034] 1) Transplant the buds of the last summer into a beautiful planting bag every spring; do not plant too deep, and ask the plants not to be skewed when planting.

[0035] 2) When the bud grafted plant sprouts in the first year after grafting, there will be 2 to 4 new buds, leaving 2 robust shoots;

[0036] 3) Before sprouting in the second year, all side branches on the main shoots should be trimmed, and the annual height of the main shoots will be measured at the end of the year;

[0037] 4) When the main shoot germinates, 4 side shoots will grow around the main shoot at the same time, remove the 4 side shoots beside the main shoot, and measure the growth of the main shoot at the end of the year;

[0038] 5) Before the shoots stop growing, the number of new lateral buds removed and left in the current year is A1: 1 bud is left every 1 node, and the annual growth of the main shoot is measured; contralateral buds are sprayed w...

[0041] Example 3 A method for arborizing multiflora ash

[0042] 1) Transplant the buds of the last summer into a beautiful planting bag every spring; do not plant too deep, and ask the plants not to be skewed when planting.

[0043] 2) When the bud grafted plant sprouts in the first year after grafting, there are 2 to 4 new buds, and 4 buds are left behind.

[0044] 3) Before germination in the second year, all side branches on the main shoots remain, and the annual height of the main shoots is measured at the end of the year;

[0045] 4) When the main shoot germinates, 4 side shoots will grow around the main shoot at the same time. Spray 200mg / L of B9 on the opposite side shoot, and measure the growth of the main shoot at the end of the year;

[0046] 5) Before the shoots stop growing, the number of new lateral buds in the current year is as per A1: 1 bud is left at every node, and 400 mg / L of B9 is used for the contralateral bud spraying to determine the annual growth of the main sho...

Abstract

The invention discloses a flowering dogwood arborescent method. The method comprises the steps that in every spring, flowering dogwood with surviving buds grafted in last summer is grafted onto a root control bag; when a plant with the grafted buds sprouts in the first year after being grafted, the number of new buds is 2-4, the first, second, third and fourth buds are obtained through fractionation, the annual increment of a main shoot is measured for comparison; before sprouting in the second year, lateral branches reserved on the main shoot are subjected to treatment of all left, all removed, one half left, one third left and one fourth left, and the annual height of the main shoot is measured at the end of the year; when the main shoot sprouts, four lateral buds can grow at the periphery of the main bud at the same time, the lateral buds are subjected to treatment of one bud left, two-bud left, three-bud left, four-bud left and all removed, and the increment of the main shoot is measured at the end of the year; before the branches stop growing, the left and removed number of the lateral buds newly growing in the current year is subjected to treatment that A1, one bud is left every two joints; A2, one bud is left every three joints; A3, one bud is left every four joints; A4, one bud is left every five joints; A5, all buds are removed, and the year increment of the main shoot is measured.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a method for arborizing multiflora ash. Background technique [0002] Cornus Florida L. is also known as Big Flower Si Zhaohua and North American Si Zhaohua, its English name is Dogwood. It is a small deciduous tree of Cornuaceae, native to eastern North America, with a height of 10m and a diameter of 30cm. Leaves ovate, opposite; flowers bisexual, four petals, small, umbels, bracts round, with obvious dents at the top. There are different scenery in the four seasons of the multi-flowered ash. It has petal-like bracts in spring, colorful leaves in summer and autumn, and orange-red berries behind the flowers. It is a high-end landscape plant and oil plant with a broad market prospect. my country is still in the introduction stage. . [0003] After the introduction, there have been changes in various places. It was originally a tree character in North America, but after b...
