Abstract
A water cultivation method of mangrove plants relates to a water cultivation method. The invention provides a water cultivation device of mangrove plants and a water cultivation method of mangrove plants, which are mainly applied to tropical or subtropical coastal brackish or brackish water lagoons in order to beautify the water surface landscape in lagoon districts and purify and stabilize the water quality in the lagoon districts. The device is provided with a floating raft, wherein floating bodies are arranged around the floating raft, and a bracket is arranged at the bottom of the floating raft; a lower fishing net layer is arranged on the bracket, and a palm layer is arranged on the lower fishing net; an upper fishing net layer is arranged on the palm layer, and a mud layer is flatly spread on the floating raft; and a top net is arranged on the mud layer. The floating raft which is well inserted with the embryonic seedlings of the mangrove plants is placed in water; the embryonic seedlings of the mangrove plants are collected for cottage, and a mash mixed by uperized red mud and heteroauxing by stirring is used as a rooting agent by which 2 to 3cm in lengths of the rooting ends of the embryonic seedlings are dipped before cuttage; after the seeds germinate, a plant nutrition liquid is sprayed at least twice, and a layer of organic fertilizer is sprinkled after the root system grows out of the palm layer; and ecological pyrethrum type pesticides are sprayed to kill pests.
Description
Technical field
The present invention relates to a kind of floating cultivation method, especially relate to a kind of floating cultivation method of mangrove.
Background technology
Mangrove is the torrid zone, the distinctive woody plant in subtropics, and it grows in the beach shoal of land and boundary, ocean band, is the very living plants in land and water that can tolerate seawater salinity few in number.As a kind of special wetlands ecosystems, mangrove forest at the windproof wave that disappears, beach protection and accretion promotion, solid bank bank protection, keep aspect such as bio-diversity and have important function.
The important ecological functions of another of mangrove are its purifying sea water functions, and it is considered to the sewage water filtration system of a kind of efficient, low cost and environment-friendly type.Therefore, the performance mangrove has positive effect at aspects such as purification of heavy metal, agricultural chemicals, life and aquaculture wastewaters.Have at present mangrove is actively introduced littoral beach and the artificial beach of lagoon, carry out the environmental ecology reparation, obtain good effect.Peng Yougui (Peng Yougui, the clean-up effect and the material balance study of mangrove forest mudflat seawater plantation-cultivating system, 2005, thesis for the doctorate) carried out mangrove forest to artificial beach---the clean-up effect research of mariculture system, the result shows that several mangroves have tangible effects of purification quality to breeding water body.But because mangrove forest mainly grows or is planted in the beach area, root system is buried in soil, and it is not remarkable to the clean-up effect of offshore water body far away.
Summary of the invention
The object of the present invention is to provide a kind of littoral salt water in the torrid zone or subtropics or brackish water lagoon of being mainly used in, be intended to beautify the water surface view of lake region, the mangrove floating cultivation device and the cultivation method of purification and stable lake region water quality.

The floating cultivation method of mangrove of the present invention may further comprise the steps:
1) on the buoyant raft of mangrove floating cultivation device, place in the water behind the good mangrove embryo of the cuttage seedling;
2) cultivation of mangrove embryo seedling and plantation: in the 4～May in every year, the mangrove embryo seedling of gathering mature and plump carries out cuttage, use before the cuttage through the red soil of high-temperature sterilization and heteroauxin and mix the pastel that forms, dip in and dye cuttage again behind embryo seedling rooting end 2～3cm place as root-growing agent;
3) rich water quality management: behind seed sprouting, spray plant nutrition liquid at least 2 times, treat that root system grows the palm fibre layer after, sprinkle one deck fertilizer again;
4) extermination of disease and insect pest: spray chrysanthemum lipid ecological agricultural chemical, kill pests.
The degree of depth that mangrove embryo seedling carries out cuttage is preferably 1/3 of 4～6cm or embryo height of seedling degree, and the cultivation spacing of embryo seedling is preferably 25～35cm.
Spray plant nutrition liquid best 3～5 times.
The present invention has following outstanding advantage: the floating bed main body is a bamboo structure, and cost is lower, has filled the thick palm fibre layer of 6～8cm in the bamboo buoyant raft, the polypropylene foam buoyancy aid of the bamboo structure of hollow and buoyant raft outer rim, and buoyancy and load-bearing are big, and anti-wave hits, and is pollution-free to water body; And whole process of cultivation is simple to operate, saves the labour; The floating cultivation of mangrove can not only purify and stabilizing water quality, can also increase the space multistory sense of lake surface view, optimizes the lake surface landscape environment.The present invention directly utilizes the floating bed technology to cultivate mangrove on the water, utilize the source of students key elements such as N, P in its flourishing root system absorption water, degraded, other pollutant of enrichment extensively utilize woody mangrove to carry out restoration of the ecosystem to the brackish lagoon of some eutrophication.The present invention is land occupation not, and operation and convenient management can be optimized view on the lake, realizes the doulbe-sides' victory of view on purifying water body and the optimization lake.
