Problems solved by technology

At present, there are few methods for propagating Halogen fern seedlings. The Chinese patent application with publication number CN 105230482 A discloses a method for establishing an in vitro regeneration system of Halogen fern, which includes explant disinfection, aseptic germination of spores, prothallus Proliferation culture, sporophyte induction and other steps, but this method is more complicated, time-consuming and consumables, the steps of tissue culture are strict and the equipment requirements for tissue culture are high, and it has not been widely used in engineering afforestation
The Chinese patent application with the publication number CN 109997532 A discloses a method for the branch propagation of the mangrove plant Halofern. This method directly cultivates the young plants containing new roots, and needs to simulate the local seawater tides for the young plants to be submerged and domesticated periodically. The processing steps are cumbersome, and the components of the plant growth regulators used are complex, the cost is high, and it is difficult to carry out large-scale seedling cultivation

Embodiment 1

[0020] A kind of simple and quick seedling raising method of mangrove plant halofern comprises the following steps:

[0021] (1) Selection of suitable forest nurseries: choose coastal mangroves and beneficial forest tidal flats to set up nurseries in the high tide zone with an average daily flooding time of 2-4 hours, remove weeds and surface litter, and level the land;

[0022] (2) Selection of mother tree: select a halogen fern plant with a plant height of not less than 1m and a crown width of not less than 1.5m without damage by diseases and insect pests as the mother tree;

[0023] (3) Matrix configuration: the soil matrix in the seedling nutrition bag is sea mud, and the bottom of the 12cm×12cm seedling nutrition bag is filled with 2cm fine sand, and then filled with sea mud; the 25cm×25cm non-woven seedling bag is filled with soil matrix , the soil matrix is ​​sea mud, and equably sprays the soil matrix (sea mud) in the seedling-raising nutrition bag and the non-woven fa...

Abstract

The invention discloses a simple and rapid cultivation method of mangrove plants, namely acrostichum aureum seedlings. The method comprises the steps of: (1), selecting a high tide zone of a coastal beach as a nursery garden, removing weeds and surface litters, and levelling land; (2), obtaining mature sporangium leaves of acrostichum aureum by shearing, and cutting the leaves into 3-5 mm fragments by using a cutter; (3), dispersing the fragments of the leaves onto the soil surface of a seedling raising nutrition bag, covering the mouth of the nutrition bag by a single-layer gauze, and fastening by using a rubber band; and (4), removing the gauze after 20-30 days, after seedlings grow for a certain period, transplanting the seedlings into a non-woven fabric seedling raising bag to culture,outplanting, and obtaining acrostichum aureum seedlings. By adoption of the method in the invention, the seedling raising survival rate is up to 90-95%; furthermore, the method is simple to operate and low in cost; a complex plant growth regulator does not need to be used; the cost is easily reduced; furthermore, the seedling raising period is short; a lot of high-quality acrostichum aureum seedlings can be obtained within a short time; and the reliable technical support can be provided for ecological restoration of tropical coastal mangroves.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a simple and rapid cultivation method for mangrove plant halofern seedlings. Background technique [0002] Halofern (Halogenaceae) is a mangrove plant widely distributed in tropical and subtropical seasides around the world, and it is also widely distributed in coastal areas such as Guangxi, Guangdong, and Hainan along the coast of China. The genus Halofern includes two kinds of plants: Halofern and Halofern acupoints. It is a marsh halophyte, born in the coastal tidal zone. The plant is tall, with up to 30 pairs of pinnae, and undergoes sexual spore reproduction. [0003] Halogen fern is a common type of mangrove plants, and it is also the only fern in mangrove plants. The rest of the mangrove plants are mostly higher plants, which are quite different from ordinary mangrove plants. It has the dual characteristics of lower plants and mangrove plants, and pl...
