Problems solved by technology

[0006] However, in the test process of using Spartina alterniflora to prepare the cultivation medium for forest container seedling cultivation, it was found that there were the following problems: there were a certain number of harmful germs and microorganisms such as germs, insect eggs, and weed seeds in Spartina alterniflora. The C-N ratio is as high as 93.7, which not only severely restricts the activity of microorganisms in the fermentation process, but also seriously hinders the normal growth of plants as a substrate; in addition, the epidermal cells on the leaves have a special structure of a large number of milky protrusions, making it difficult to evaporate water. It is not easy to dry under natural conditions, so it is difficult to crush; its physical and chemical properties also have limitations, and it is not suitable for use as a cultivation substrate alone, but needs to be mixed with other auxiliary materials to change the three-phase ratio of solid, liquid, and gas. Nutrient content and structure to meet the needs of plant growth and development

Embodiment 1

[0021] Embodiment 1: (utilize Spartina alterniflora to prepare the method 1 of forest tree container seedling cultivation cultivation substrate)

[0022] (1) Collection and drying of Spartina alterniflora stalks: after October every year, the mature Spartina alterniflora stalks are harvested and cleaned, and turned in the sun for several days until the water content is 21%;

[0023] (2) Pulverization: pulverize the dried Spartina alterniflora stalks to 5 mm and pass through a Φ=5 mm sieve to obtain Spartina alterniflora powder;

[0024] (3) Fermentation and decomposing of grass powder and sterilization: mix Spartina alterniflora powder, urea and gypsum powder in a ratio of 35%: 3%: 0.5% by weight, make up to 100% with water, mix and mix well; cover After the plastic film is fermented for 40 days, the temperature of the material during the fermentation process reaches 55-60 ° C, so after 4-5 days of fermentation, the film is removed, the material is spread, the temperature is l...

Embodiment 2

[0027] Embodiment 2: (utilize Spartina alterniflora to prepare the method 2 of forest tree container seedling cultivation cultivation substrate)

[0028]In this example, step (1) dries the water content of Spartina alterniflora stalks to 25% in a dryer mode; in step (3), the weight percentages of Spartina alterniflora powder, urea and gypsum powder are 37%: 2 %: 0.8% ratio, and make up to 100% with water, and ferment altogether after covering plastic film for 45 days; Spartina alterniflora powder after fermentation in step (5) and carbonized rice husk are mixed by volume 6: 4 ratio, stir Uniform; All the other steps and technology are the same as in Example 1.

Embodiment 3

[0029] Embodiment 3: (the method 3 that utilizes Spartina alterniflora to prepare forest tree container seedling cultivation medium)

[0030] In this example, in step (1), the water content of Spartina alterniflora stalks is dried to 30% in the manner of continuous sunning; in step (3), the weight percentages of Spartina alterniflora powder, urea and gypsum powder are 38%: 1% : 1% ratio, and make up to 100% with water, and ferment altogether after covering plastic film for 50 days; Spartina alterniflora powder after fermentation in step (5) and carbonized rice husk mix by volume 5: 5 ratio, mix well ; All the other steps and technology are the same as in Example 1.

Abstract

The invention discloses a method for preparing forest container seedling culture substrate by utilizing Spartina alterniflora Loisel, belonging to the technical field of plant resource utilization. The method comprises the following steps: (1) collecting Spartina alterniflora Loisel straws, drying; (2) grinding; (3) fermenting grass meal, sterilizing; (4) carbonizing rice hulls; and (5) performing mixing and other steps to obtain the composite substrate. The method disclosed by the invention is simple and practical; the resources of Spartina alterniflora Loisel is rich, thus the production cost of the substrate is reduced by 46.8%-54.8% compared with the peat substrate; and the seedling effect is similar to peat. Therefore, the resource utilization of Spartina alterniflora Loisel can be realized, the dependence on the peat substrate can be reduced, and the method is an ecological resource utilization technology and has remarkable economic, social and ecological benefits. The inventioncan be popularized and applied in coastal areas.

Description

technical field [0001] The invention relates to the technical field of plant resource utilization, in particular to a method for preparing a forest tree container seedling cultivation medium by utilizing the stem resource of Spartina alterniflora, an invasive species. Background technique [0002] Tree container seedling raising is an advanced seedling raising technology in forestry in the world today. Forest tree container seedlings can effectively improve the survival rate of afforestation due to the advantages of short seedling period, long afforestation season, easy control of specifications and quality, saving seeds, not easy to damage the root system when raising seedlings, less water loss of seedlings, high survival rate of afforestation, and short seedling slowing period. It can greatly improve the quality of afforestation, and it is widely promoted and applied all over the world. [0003] Seedling substrate is an important carrier for the growth and development of ...
