Problems solved by technology

Due to the late cooling time in Guangxi and the small temperature difference between day and night, there are generally problems such as poor discoloration effect, unstable discoloration, discoloration (color) but not bright, discoloration (color) but not beautiful, etc. The function of landscape
However, the research on sweetgum sweetgum at home and abroad mainly focuses on chemical components and its medicinal properties, seedling breeding technology, community structure and population genetic diversity, etc., but there are few reports on how to promote the early color change of sweetgum sweetgum and prolong the color change period of sweetgum sweetgum

Embodiment 1

[0017] A spraying agent for promoting the discoloration of liquidambar leaves. The raw material components and content of the spraying agent are 100 mg / L abscisic acid + 6 mmol / L citric acid + 4 mmol / L salicylic acid + 200 mg / L sucrose.

[0018] The preparation method of described spraying agent is:

[0019] Step 1, weighing, weighing each component according to the following requirements, abscisic acid 100mg, citric acid 6mmol, salicylic acid 4mmol, sucrose 200mg, the balance is water, and the total volume of the above is 1L;

[0020] Step 2, mixing, mixing and dissolving weighed abscisic acid, citric acid, salicylic acid and sucrose in water to prepare the spraying agent.

[0021] The method of using the spraying agent: from mid-October to late December, every 10-15 days, in the weather without rain, spray at 16:00-18:00, put the spraying agent into After the mist applicator, evenly spray the leaves of the sweetgum seedlings, and spray each time until the leaves are drippin...

experiment example 1

[0023] 1. Test material

[0024] The test materials were 3-year-old sweetgum seedlings with consistent growth and good growth, and their provenance was Batou Township, Debao County, Baise City, Guangxi.

[0025] 2. Experimental design

[0026] The experiment was conducted from October 15, 2020 to January 25, 2021 at the scientific research nursery base of Guangxi Academy of Forestry Sciences. The test is divided into two stages. The first stage is the leaf spraying test. When the spraying concentration is 0 and the leaves change color by nearly 50%, the spraying test will be stopped. The test time of this stage is: 2020 From October 15th to December 25th, 2021, the test factors included four kinds of abscisic acid (A), citric acid (B), salicylic acid (C), and sucrose (D), and each factor had four levels (Table 1). 1), choose L 16 (4 5 ) table for orthogonal design (Table 2). Each treatment of 10 liquidambar seedlings, every 10-15 days, under the weather without rain, even...

Abstract

The invention discloses a spraying agent for promoting liquidambar formosana hance leaves to change color. The spraying agent comprises the following raw material components: 100 mg / L of abscisic acid, 6 mmol / L of citric acid, 4 mmol / L of salicylic acid and 200 mg / L of sucrose. When the spraying agent is used, the spraying agent is sprayed at 16: 00-18: 00 every 10-15 days in a non-raining weather from the middle ten days of October to the last ten days of December; and the spraying agent is loaded into a vaporific spraying device, and then the spraying agent is uniformly sprayed to leaf surfaces of seedlings of liquidambar formosana hance every time until the leaf surfaces drop liquid. The spraying agent can promote synthesis of anthocyanin and tannin in liquidambar formosana hance cells, so that liquidambar formosana hance leaves can be promoted to become red; and meanwhile, the color changing period can be prolonged, and the ornamental value of liquidambar formosana hance is improved.

Description

technical field [0001] The invention belongs to the technical field of garden plant maintenance, and relates to a spraying agent for promoting discoloration of sweetgum leaves. Background technique [0002] Liquidambar formosana Hance is a deciduous tree belonging to the genus Liquidambar of the family Hamamelidaceae. It is widely distributed and is one of the main forest tree species in southern my country. Liquidambar has strong adaptability and fire resistance. It is known as the pioneer tree species of barren hills. After autumn, its leaves gradually change from green to red. It has great ornamental value and is an excellent urban landscape tree species. Due to the late cooling time in Guangxi and the small temperature difference between day and night, there are generally problems such as poor discoloration effect, unstable discoloration, discoloration (color) but not bright, discoloration (color) but not beautiful, etc. The function of landscape. However, the research...
