Caused people to produce mistaken ideas to the scarcity of seaweed seeds research in the past, namely seed to sea grass bed to keep regeneration function little.But nearest studies show that, seed be except can keep genetic diversity, the development on patch grassland is played a decisive role, and the grassland that is interfered utilize seed repair than simple utilization nourish and generate and recover fast.Zostera marina is a kind of of sea grass, and it can produce the seed of a large amount of small sizes, and convenient transportation is less to ecosystem grassland interference, and can keep the genetic diversity on grassland, so planting seed is a kind of method of effective recovery sea grass bed.Yet the method for at present known collection grass wrack seeds is mainly to utilize fishing net to fish for or directly manual collection in the grass wrack seeds mature period.Although the grass wrack seeds maturity of utilizing above-mentioned grass wrack seeds collection method to collect is fair, also there are some problems simultaneously.The one, the ecosystem grassland is destroyed large, when utilizing fishing net to fish for seed, will certainly injure part length has not yet the breeding branch of mature seed and the blade of vegetative shoot, thereby to the ecosystem grassland causing than havoc; The 2nd, the activity duration is short, and the grass wrack seeds maturation namely comes off afterwards, therefore begins to collect seed when grass wrack seeds is ripe again, and the activity duration is short, can not satisfy the collection of extensive seed at once; The 3rd, collection efficiency is low, and when grass wrack seeds was ripe, grassland plant cover degree was very high, brings very large inconvenience for the operation of fishing net, and grass wrack seeds is smaller, and manual collection is also very time-consuming.
Summary of the invention
For overcome that existing grass wrack seeds collection method exists to the ecosystem grassland destroying the deficiency large, that the activity duration is short, collection efficiency is low, the invention provides a kind of method of collecting grass wrack seeds, the method not only can be collected grass wrack seeds on a large scale, and collection efficiency is high, activity duration is long, and is little on ecosystem grassland impact.
The technical solution adopted for the present invention to solve the technical problems is: comprise that Zostera marina reproduction branch collection and processing, Zostera marina reproduction branch are supported temporarily and grass wrack seeds results and a kind of grass wrack seeds collection method of preserving.
Above-mentioned Zostera marina reproduction branch collection be treated to: be about to the mature period at grass wrack seeds, the manual Zostera marina reproduction branch that gathers removes the upright stalk of reproduction branch.
Above-mentioned Zostera marina reproduction branch is supported temporarily: the Zostera marina reproduction branch that will the remove upright stalk mesh bag of packing into, but the mesh bag mouth is sewed with the tie of pull colligation, after the reproduction branch of packing into, with the tie pull of mesh bag mouth, fasten; Then, tie at the middle part of a well rope rope, there is a buoy in well rope rope one end system with several mesh bag colligations that the reproduction branch is housed together, and there is sinker in other end system, and what be linked to be a Zostera marina reproduction branch supports device temporarily; To support temporarily at last device and put into the nature marine site.
Above-mentioned grass wrack seeds is gathered in the crops and is saved as: after supporting a period of time temporarily, to support temporarily device and fetch, take off mesh bag, the reproduction branch will be poured in container, fully stir, after standing a period of time, the immature seed of pulling the reproduction branch out and floating on the surface filters, nature seawater rinses, pour in the container that nature seawater is housed, the collection of grass wrack seeds is completed in sealing.
The invention has the beneficial effects as follows, activity duration is long, can collect on a large scale grass wrack seeds, and Zostera marina reproduction branch is supported temporarily device and made with simple to operate, recyclable recycling, can take full advantage of the condition such as seawater, illumination, nutrition, temperature in nature marine site, not only cost is low, alleviates the labour intensity of seed collection, and seed collection efficient is high, seed quality is good, is about to ripe Zostera marina reproduction branch owing to only gathering, and is little on ecosystem grassland impact.
