Problems solved by technology

[0005] However, the existing nurseries are mostly distributed in sandy soil areas with poor nutrients in the coastal areas, and it is difficult to bury fertilizers and apply nutrient solutions due to the natural tide of seawater. Many seedlings are easy to break or even die, and the survival rate of seedlings is greatly affected

Abstract

The invention belongs to the technical field of planting, and particularly relates to a method for transforming a coastal culture pond into a mangrove forest nursery garden. A tidal irrigation system is adopted, and a nutrient solution is added into the mangrove forest nursery garden. The tidal irrigation system comprises a planting ridge and a main water channel, wherein the main water channel communicates with external seawater through a water gate in a controlled mode, and the main water channel communicates with the planting ridge through a water control pipe. The water control pipe is composed of a water control straight pipe and a bent pipe. One end of the water control straight pipe communicates with one end of the bent pipe and can be freely detached, an opening in the other end of the water control straight pipe communicates with the planting ridge, and an opening in the other end of the bent pipe communicates with the main water channel. According to the method for transforming the coastal culture pond into the mangrove forest nursery garden, seawater flooding time and flooding depth can be well controlled, healthy and rapid growth of seedlings can be promoted, the survival rate of the seedlings can be guaranteed, and mangrove forest seedlings required by a peripheral pond returning and forest returning project, coastal mangrove forest afforestation and mangrove forest ecological restoration project can be supplied by modifying the culture pond on site for a seedling culture field.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for transforming a coastal culture pond into a mangrove nursery. Background technique [0002] Mangrove refers to the tidal flat wetland woody biome composed of evergreen shrubs or trees that grow in the upper part of the intertidal zone of tropical and subtropical low-energy coasts and are flooded by periodic tides. Composed species include herbs, vines and mangroves. It grows in tidal flats and shoals at the junction of the land and the ocean, and is a special ecosystem where the land transitions to the ocean. It is an integral part of the special coastal wetland ecosystem and the important intertidal forest ecosystem, and has the functions of preventing wind and waves and protecting the coast. [0003] There is no shortage of methods for mangrove seedling cultivation in the prior art. For example, Chinese patent application CN 103283475 A discloses a me...
