Problems solved by technology

On the other hand, slopes are more prone to compaction, which further limits the germination of spores
These conditions limit the sowing of fern spores to a certain extent, making it impossible to spray them in the same way as herbaceous seeds
There is as yet no suitable method of seeding ferns during slope restoration

Embodiment 1

[0034] Pteris fern has wide adaptability, strong resistance, and is not easily affected by diseases and insect pests during the growth period. It is an excellent slope understory plant. The fern sowing method of the present invention will be described below with Pteris fern as an example.

[0035] 1. Collection of Spores

[0036] When the sporangia of Pteris fern are dark brown or yellow and are about to fall off but the spores have not been released, collect them in envelopes or clean paper bags. Put the collected sporophyll on the newspaper, and in a warm and dry environment, after drying in the shade for 2-3 days, many spores will pop out after the sporangia burst. The spores are tens of microns in size, powdery, and earthy yellow. Carefully remove impurities and wrap them in envelope paper or sulfuric acid paper. They should be harvested and sown together, or stored in a refrigerator at 4°C. The storage period should not exceed 1 year.

Embodiment 3

[0056] A kind of seeding method of fern, comprises the following steps:

[0057] (1) Put the collected spores under the ultraviolet light for 1 hour, then use MS nutrient solution to form a suspension, and let it stand at room temperature for 18 hours;

[0058] (2) Crushing the buoyancy-preserving Kele matrix, controlling the diameter of the treated buoyancy-preserving Kele matrix to be about 0.6 cm, and soaking the treated buoyancy-preserving Kele matrix in carbendazim at an appropriate concentration for 2 hours;

[0059] (3) Squeeze the carbendazim-treated buoyant Kele matrix to remove the absorbed moisture to the greatest extent;

[0060] (4) Put the water-controlled floating Kele substrate into the spore suspension, so that the MS nutrient solution is submerged in the sponge substrate for 2-3 cm, stir well with a glass rod, and let it stand for 2 hours to ensure that the spores can fully adhere to the sponge substrate. In the surface voids of the buoyant Kellogg matrix. ...

Abstract

The invention provides a sowing method suitable for pteridophytes in a slope restoration process. The sowing method of the pteridophytes comprises the steps as follows: step 1, immersing a polyurethane substrate in a spore suspension of pteridophytes to obtain a polyurethane substrate attached with spores; step 2, performing sowing. According to the method, the spores are adsorbed onto the polyurethane substrate, the polyurethane substrate plays two roles in the germination process of the pteridophytes: on one hand, the polyurethane substrate can provide a growth carrier for the spores and prevent the condition that the mitoplast at the initial stage of germination of spores cannot grow into young gametophytes easily due to coverage of spores with soil or other types of substrates in the sowing process, on the other hand, the good porosity structure of the polyurethane substrate can provide specific microenvironments for growth of sporophytes at the early stage, guarantee air, moisture, nutrients and the like required by growth of the sporophytes and greatly increase the survival rate of the spores.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a method for sowing ferns. Background technique [0002] Natural landslides, soil erosion, rock weathering, and human activities such as building roads, railways, mining, and engineering construction often destroy natural vegetation and leave many exposed slopes. The self-recovery process of bare slope vegetation is often relatively slow, and the artificial restoration method, that is, the slope restoration project, can change the direction and speed of ecosystem succession in the self-recovery process to a certain extent, and shorten its recovery period. At present, slope restoration has become an important part of ecological environment construction. The plant configuration mode adopted in the current mainstream slope restoration process is mainly the mode of combining trees, shrubs and grasses with ecological engineering. However, in the actual application process, it is...
