Mangrove plant seedling raising substrate and seedling raising method

Abstract

The invention relates to the technical field of mangrove plant seedling raising, in particular to a mangrove plant seedling raising substrate and a seedling raising method. The substrate comprises beach sludge, sea sand, branch fertilizer, chicken manure and an AM microbial inoculum, and the volume ratio of the beach sludge to the sea sand to the branch fertilizer to the chicken manure to the AM microbial inoculum is (50-80): (10-40): (5-30): (5-15): (1-10). According to the mangrove plant seedling raising substrate, by adding the branch fertilizer into the substrate, the branch fertilizer enables the substrate to be loose and porous, and therefore development of mangrove plant roots is facilitated; in addition, the branch fertilizer serves as long-term fertilizer to supply fertilizer to mangrove plants for a long time, relative to the branch fertilizer, the chicken manure serves as short-term fertilizer to conduct early-stage fertilization on the mangrove plants, and the chicken manure and the branch fertilizer are complementary in fertilizer supply effect, so that nutrients are provided for growth of the mangrove plants. Subsequent frequent fertilization is reduced, and investment and cost of manual management are reduced.

Description

technical field [0001] The invention relates to the technical field of mangrove plant seedling cultivation, in particular to a mangrove plant seedling cultivation substrate and a seedling cultivation method. Background technique [0002] The mangrove ecosystem is an important ecological key area of ​​the coast. It has multiple functions such as wind and wave protection, embankment protection, siltation promotion, land reclamation, pollution purification, and ecological balance maintenance. It is also an important habitat for waterfowl. A place where shellfish grow and reproduce. Due to the development of economic industries in the coastal zone, the mangrove ecosystem has suffered serious damage. The protection and restoration of the mangrove ecosystem has been highly valued by scholars and government leaders. [0003] Mangrove afforestation is the most direct and effective way to restore the mangrove ecosystem. Nutrient bag seedlings are often used for mangrove afforestat...

AI Technical Summary

Problems solved by technology

Nutrient bag seedlings are often used for mangrove afforestation. Due to the harsh afforestation conditions and the low survival rate of afforestation, the recovery effect of the mangrove ecosystem is poor.
