A kind of simple and rapid cultivation method of mangrove plant halofern seedlings

Abstract

The invention discloses a simple and rapid cultivation method for mangrove plant halofern seedlings. The method comprises the following steps: 1) selecting the high tide zone of the coastal beach as a nursery, removing weeds and surface litter, and leveling the land; 2) cutting the mature sporangium leaves of the fern, and cutting the leaves into 3-5mm pieces with a cutting knife 3) spread the leaf fragments to the soil surface of the seedling-growing nutrition bag, cover the mouth of the nutrition bag with a single layer of gauze, and tighten the rubber band; 4) remove the gauze after 20-30 days, and transplant the seedlings after a period of time when the seedlings grow Cultivate it in a non-woven seedling bag, and get out of the nursery to get the fern seedlings. The survival rate of seedlings raised by the method of the present invention is as high as 90%-95%, and the operation is simple, the cost is low, and no complex plant growth regulator is used, which is beneficial to reduce costs; in addition, the seedlings have a short cycle, and a large amount of high-quality plants can be obtained in a short time. Halogen fern seedlings provide a reliable technical guarantee for the ecological restoration of tropical coastal mangroves.

Description

technical field [0001] The invention belongs to the technical field of plant reproduction, and in particular relates to a simple and rapid cultivation method for mangrove fern seedlings. Background technique [0002] The genus Halophylla (Halofernaceae) is a mangrove plant that is widely distributed in tropical and subtropical seasides around the world, and is also widely distributed in coastal areas such as Guangxi, Guangdong, and Hainan along the coast of China. The genus Halophylla includes two kinds of plants: Halogena fern and Halogena cuspidatum. It is a swamp halophyte and is born in the coastal tidal zone. [0003] Halo fern is a common species of mangrove plants, and it is also the only fern in mangrove plants. Most of the other mangrove plants are higher plants, which are quite different from ordinary mangrove plants. It has the dual characteristics of lower plants and mangrove plants, and plays an important role in the ecological restoration of mangroves. At pre...

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
