Description

Seaweed transplanting device and seaweed transplanting method

Technical Field

The invention relates to the field of seaweed transplantation and ecological restoration, in particular to a seaweed transplantation device and a seaweed transplantation method.

Background

Sea grass is a marine higher plant, not only can provide strong primary productivity, but also has strong ecological function. The large-area seaweed bed formed by the seaweed is called three typical marine ecosystems together with the coral reef and the mangrove forest. The seaweed bed not only can stabilize geology, purify water and store blue carbon (sealing and storing 15% of marine organic carbon), but also provides a habitat, a spawning site and a bait station for a plurality of marine organisms. At present, due to the influence of human activities and the change of natural environment, approximately one third of the ecological systems of the seaweed bed are degraded and disappear, and at present, the method for repairing the seaweed bed mainly comprises a seed sowing cultivation method and an adult transplantation method. The seed sowing cultivation method has less application in natural habitat restoration because seaweed seeds are smaller and lighter, have high fixing difficulty, are easy to be washed by seawater and the like. Adult transplantation is widely used. The adult transplanting method is a method for achieving restoration by selecting healthy donor plants from a natural seaweed bed according to scientific planting density by utilizing the characteristic that seaweed can utilize rootstocks for asexual propagation, transplanting the donor plants to a restoration area by utilizing a device and a technology, and forming a patch grass bed through scientific maintenance and management. The transplanting method is divided into two treatment methods for plants: 1. rhizome method: the plants with the rootstocks are bound on a carrier and then put into a repair area. 2. Turf and turf grass transplanting with substrate mud.

There are many devices currently used for seaweed transplantation, for example, CN112449815B and CN112335541A disclose a cart-type transplantation device with a walking frame carrying a transplantation device, which is light and small but suitable for operation only in low-tide and near-shore areas, and is limited in flood tide and deep water due to its light weight and the need for power towing. CN212212242U discloses an offshore suspended type soilless seaweed transplanting device, which is used for transplanting seaweed on the sea surface, and growing the transplanted seedlings by using nutrient elements in the sea water, but the amount of nutrient substances required by the growth of the seaweed is not constant in the sea water, and the content in the sea water does not necessarily meet the growth requirement of the seaweed, so that the survival rate of the transplanted seedlings cannot be guaranteed in the long term.
