Problems solved by technology

[0003] There are few studies on Acer catalpa. In the existing published literature, Yu Daoping and others published "Biological characteristics of Acer catalpa seeds" in "China Wild Plant Resources" and Ma Wenbao and others published in "Seeds". The "Preliminary Study on the Germination Characteristics of the Rare Plant Acer catarrhalis Seeds" on the Internet has studied the germination of the Acer catarrhalis, but the germination rate is below 50%, and the germination rate is low
The lower germination rate further affects the cultivation of Acer catalpa seedlings.
[0004] At present, the research on the cultivation of Acer catalpa seedlings is limited to scientific research experiments, and there is no method for its large-scale cultivation, which seriously limits the protection and breeding of the endangered plant Acer catalpa

Embodiment approach

[0062] According to a preferred embodiment of the present invention, step 2 includes the following sub-steps:

[0063] Step 2-1, taking out the samara preserved in step 1, peeling off the samara to obtain seeds with different plumpness inside the samara;

[0064] Step 2-2, screening and cleaning seeds with different plumpness to obtain plump seeds;

[0065] Step 2-3, taking the plump seeds obtained in step 2-2, peeling off the seed coat, and obtaining the seed kernel;

[0066] Step 2-4, germinating and culturing the seed kernels obtained in step 2-3.

[0067] According to a preferred embodiment of the present invention, in step 2-1, the fruit wing includes two symmetrical parts. When peeling off, the fruit wing is divided into two halves from the middle, the fruit wing is peeled off from the joint, and the middle part is taken out. seed.

[0068] Wherein, removing the outer fruit wing of the samara can obtain the seeds positioned at the inside of the samara, but the quality...

Embodiment 1

[0140] (1) Collect the samara when the fruit wings of the Acer catalpa samara start to turn yellow, wash them with clear water, and then air-dry them for 2 hours to remove the moisture on the surface of the fruit wings and keep the moisture of the seeds themselves. Put the air-dried samara into a ziplock bag, minus the four corners of the ziplock bag and leave 1×1cm in the middle 2 The holes are large and small to facilitate the respiration of the seeds, and they are stored at a low temperature of 4°C for 30 days.

[0141] (2) After 30 days, take out 100 samara preserved in low temperature, divide the samara into two halves from the middle, peel off the samara from the junction, take out the seeds in the middle, soak the seeds in clean water, remove the seeds floating on the water surface, and then wash Seeds that sink to the bottom get plump seeds. Gently peel off the seed coat from the cotyledon of the seed with a scalpel to obtain the seed kernel. Spread two layers of fil...

Embodiment 2

[0148] Repeat the process of Example 1, the difference is: in step (1), the samara is air-dried for 1.5h, and stored at 2°C for 40d; in step (2), when germination is carried out in water, the water has not passed the seed 1 / 3 place of thickness; In step (3.1), keep air humidity to be 60%, the water content rate of cultivation soil is 20%; In step (3.2), the air humidity at the beginning of control is 60%, cultivation is The moisture content of the soil is 20%.

[0149] Wherein, the average germination rate was 92%, and the growth rate and survival rate of seedlings were similar to those in Example 1.

Abstract

The invention discloses a method for culturing an acer catalpifolium plantlet. The method comprises the steps that firstly, key fruits are collected, treated and preserved for 20 d to 40 d at low temperature; then sequential stripping is carried out to remove fruit wings and seed coats of internal seeds, kernels are obtained, and the kernels are soaked in water for sprouting; finally, culture is carried out in soil for culture, and the acer catalpifolium plantlet is obtained. The sprouting rate is increased at the earlier stage, and the soil for culture, air humidity, the water content of the soil for culture and the like are strictly controlled during later culture, so that the survival rate of the acer catalpifolium plantlet is remarkably increased.

Description

technical field [0001] The invention relates to the field of Acer catalpa, in particular to the field of seedling cultivation of Acer catalpa, in particular to a method for cultivating seedlings of Acer catalpa. Background technique [0002] Catalpifolium (Acer amlum subsp. catalpifolium (Rehder) Y.S. Chen), also known as Catalpifolium subsp. Catalpifolium (Rehder) Y.S. Chen, is a plant of the genus Acer in the Aceraceae family. It is a rare and endangered tree species endemic to my country. The second-level key protected plants are scattered in the central plains of Sichuan and northern Guizhou. They are scattered in subtropical evergreen broad-leaved forests at an altitude of 500-1300m. During August-September, the tree has beautiful shape, tall trunk, hard and dense material, and is an excellent tree species for greening and timber. As a very small population of Acer catalpa, it is extremely rare in various production areas and has been endangered due to deforestation and ...
