specific Embodiment 1

[0034] The essence of the present invention will be further described below in conjunction with specific embodiments.

[0035] The cultivation method of a kind of mangrove big seedling that present embodiment relates to is characterized in that comprising the steps:

[0036] 1) Select a nursery site, choose muddy reclamation tidal flats with small wind waves, low salinity, and fresh water supply (that is, muddy tidal flats formed after reclamation), use furan erysipelas to kill harmful organisms after removing weeds, and use it as a nursery for seedling cultivation, namely nursery ground; the harmful organisms include insects and crabs;

[0037] 2) Nutrient bag seedling cultivation, the nutritional bag is equipped with a seedling substrate, and the viviparous mangrove plants are directly raised in the nutritional bag; for the seed mangrove plants, the seedlings are raised in the seedbed first, and then moved into the nutritional bag for cultivation; the nutritional bag The se...

Abstract

The invention relates to a potting technology for mangrove forest seedling cultivation, which is characterized by comprising the steps of 1) selecting a seedling cultivation field, wherein muddy inning intertidal zones with weak storm, low salinity and fresh water supply are selected; 2) cultivating the seedlings in a nutrition bag, wherein a seedling cultivation matrix is filled in the nutrition bag, and direct seedling cultivation with the nutrition bag is adopted for vivipary mangrove forest plants; 3) transferring the bagged seedlings into pots, wherein plantlet grows up after the seedling is cultivated for 0.5-1 year in bags according to the method of step 2, and then the plantlet is transplanted to a plastic seedling cultivation pot for seedling cultivation; 4) cultivating the potted seedling, wherein the seedling cultivation is carried out after the plantlet is transplanted into the plastic cultivation pot and arranged in a nursery garden, and water and fertilizer management, reshaping and trimming as well as pest control are strengthened in the seeding cultivation process; and 5) outplanting of the seedling, wherein the mangrove forest seedling is cultivated after the plantlet transplanted in step 4) grow for 1-2 years in the plastic seedling cultivation pot. At the time, the seedlings can be transferred out of the nursery garden to be used for recovery of the mangrove forest of the inshore intertidal zone and greening of the coastal intertidal zone. The seedlings cultivated by the technology disclosed by the invention has the characteristics of being high in degree of lignification of the stem, complete and dense in roots and the like; and compared with plantlets of the mangrove forest, the seedlings have stronger adaptive capacity to hard intertidal zones and severe growing environments.

Description

technical field [0001] The invention relates to a potted technique for cultivating large mangrove seedlings, in particular to a method for cultivating large mangrove seedlings using the potted technique. The invention belongs to the technical field of mangrove seedling cultivation. Background technique [0002] Mangrove forest is a woody community that grows in the intertidal zone of tropical and subtropical coasts and is inundated by periodic seawater. Mangroves are one of the important ecological environments of tropical and subtropical coasts. They are good coastal shelter belts and ideal places for marine organisms to multiply and inhabit. They have social, ecological and economic benefits. [0003] After the 1980s, with the development of coastal society and economy, disturbances such as deforestation and breeding, poaching of economic animals in forest areas, and seawater pollution have become more and more serious, resulting in the reduction of mangrove resources, wh...
