Problems solved by technology

The results of landscape trees will not only affect the growth of the tree, but also pollute and corrode the road surface after the mature seeds fall naturally, and emit a special odor, which affects the environment
The normal planting of ginkgo often has the phenomenon of "fake death" and "fake life". The commonly used cutting techniques are generally in the selection of branches. The selection of cuttings is unscientific, and the cutting is too long or too short. Insert directly into the seedbed

Embodiment 1

[0044] (1) Selection of seedling container

[0045] Commonly used seedling containers include plastic film containers, hard plastic cups, mesh bag containers made of degradable fiber materials, and containers made of kraft paper. Under the premise of ensuring the effectiveness of afforestation, small-sized containers (such as plastic film containers with a diameter of 9 cm ×14 cm); if the afforestation is in the dry season and the site conditions are poor or under the canopy, a larger container (such as 12 cm×16 cm) should be selected. This technique refers specifically to hard plastic cups with a size of 12 cm×14 cm.

[0046] (2) Types of seedling substrates and disinfection

[0047] Seedling-raising substrate: a mixture of peat, perlite, and vermiculite, and the three are mixed according to the ratio of peat: perlite: vermiculite of 3:2:2.

[0048]Disinfection: use 40% formalin solution to dilute 800 times to sprinkle the substrate, and the moisture content of the substrat...

Embodiment 2

[0070] The difference from Example 1 is the use of twig cuttings. The preparation of the branches is in the first ten days of July, and the young semi-lignified branches of the year are used as cuttings, and they are cut into two-bud or three-bud one-node cuttings. The cutting time is between summer and summer. In the morning and evening in autumn or on cloudy days, cut off the branches and leaves of the cuttings that are buried in the soil before cutting. Generally, the survival rate of soft branch cuttings is higher than that of hard branch cuttings.

[0071] Effect description:

[0072] The present invention uses the hard branches or twigs of Ginkgo biloba as cuttings. The lower end 2 cm of the cuttings is dipped in root powder or naphthalene acetic acid solution with a concentration of 1000 mg / kg. In the container, under the control of water, temperature and humidity of the above conditions, the callus can be formed in about 10 days, and the roots will gradually take r...

Abstract

The invention discloses a gingko container cutting seedling method. The method comprises the following steps that firstly, a seedling container is selected; secondly, seedling matrix kinds are selected, disinfection is carried out, and the seedling matrix is the mixture of grass carbon, perlite and vermiculite; thirdly, a seedbed is established; fourthly, cutting seedling is carried out, hard branch cutting or twig cutting is selected, and cutting preparation, cutting slip shearing, cutting slip processing and cutting are included; fifthly, container seedlings are managed, and water management, light management, nutrient management, insect pest and weed prevention and matrix refill are included. By means of the method, the survival rate of the cutting seedling can be improved, the supply number of ginkgo seedlings is increased, the seedling cost is reduced, the gingko seedlings can be selectively cultivated in a directed mode according to the purpose of the seedlings, and a feasible scheme is provided for the application of a large number of the gingko seedlings in production.

Description

technical field [0001] The invention belongs to a method for growing seedlings of plants, in particular to a method for growing seedlings by container cutting of ginkgo branches. technical background [0002] ginkgo( Gingko biloba L.) belongs to the genus Ginkgo biloba, an ancient relic tree species in my country, and is known as the "living fossil" of the plant kingdom. Ginkgo is widely distributed in my country, and it integrates edible, medicinal, material, health care, greening and ornamental. Ginkgo biloba leaves contain bioactive substances such as flavonoids, and are the first choice for the production of drugs for the treatment of cardiovascular and cerebrovascular diseases. Ginkgo biloba is dioecious. Studies have shown that the content of medicinal components in the leaves of different plants is significantly different, and the medicinal components such as flavonoids in the leaves of male Ginkgo plants are significantly higher than those in female plants. It is u...
