Abstract
The invention discloses a method for cage cultivation of myriophyllum spicatum and belongs to the fields of water environmental protection and water ecological reconstruction. The myriophyllum spicatum is planted in a suspension cage and light requirements in water can be met through adjustment of suspension depth. The suspension cage comprises floating bodies and a cage which are connected through ropes. The method includes the steps: arranging the suspension cage in a water body with water depth exceeding 1.5 meters; inoculating the myriophyllum spicatum starting from March each year; breeding plagiognathops microlepis or silver todarades in the cage; monthly measuring change of water transparency from April to October each year and adjusting the suspension depth according to the water transparency; harvesting the myriophyllum spicatum during October and November each year. By the method, the myriophyllum spicatum can fixedly grow on a bottom substrate of the cage, the myriophyllum spicatum can be prevented from being chewed and eaten by herbivorous fishes, infringement of stormy waves upon plants can be resisted, and an introducing problem of the myriophyllum spicatum is solved.
Description
Technical field
The invention belongs to water environment protection, Ecology rebuilds field, relates to a kind of method of cage cultivation of myriophyllum spicatum.
Background technology
Current China surface water quality of water environment is generally poor, eutrophication general (N, P in water body are more), has a strong impact on that water supply quality, Ecology are stable, water landscape and aquaculture.
Haloragidaceae Myriophyllum spicatum is the common water plants of China, adaptable, all can physically well develop in various water body, belong to sun plant, relative to other submerged plants, have higher photosynthesis rate, growth rapidly, there is N, P in good absorption water body and increase the effect of water transparency, through being often used as pioneer in Freshwater ecosystems reconstruction.But its growth is subject to the restriction of Underwater Optical photograph, be difficult to field planting in the eutrophication water of the depth of water more than 2 meters, therefore revise in engineering in the small-sized eutrophic lake of part drainage very well equipped, the ecology in river, usually adopt the method reducing water level to promote that the field planting of Haloragidaceae Myriophyllum spicatum grows.But for most of lake, reservoir and river, be difficult to carry out accurate artificial water level and regulate, which limits the introducing of Haloragidaceae Myriophyllum spicatum, thus limit the restoration and reconstruction of the ecosystem.There is researcher to explore and solve this problem by the mode of adjustable submerged vegetation net bed, but this technology has following shortcoming: (1) this technology utilizes folder seedling method to be tied up on mesh by heavy water plant and is fixed, labour intensity is large, is only applicable to small-sized demonstration project, is not easy to carry out large-scale promotion; (2) this technology adopts monolayer net as carrier, causes submerged plant easily to be gnawed by herbivorous fishes, affects field planting effect; (3) capacity of anti-storm is poor; (4) plant root is without field planting matrix, affects growth conditions.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art and deficiency, a kind of method of cage cultivation of myriophyllum spicatum is provided.The present invention is by the mode of enclosed type cage culture, make Haloragidaceae Myriophyllum spicatum set growth in net cage bottom substrates, after transparency increases (underwater irradiance increase), progressively increase net cage again and hang the degree of depth, the most deeply can reach the degree of depth of 5 meters, thus solve the introducing problem that deep water water ecology rebuilds pioneer.
Object of the present invention is achieved through the following technical solutions:
The method of cage cultivation of myriophyllum spicatum, for planting a Haloragidaceae Myriophyllum spicatum in suspension net cage, hangs the degree of depth (the suspension degree of depth is defined as the degree of depth to the water surface bottom net cage) to meet the requirement of illumination in water by regulating.Described suspension net cage comprises buoyancy aid, rope and net cage, and buoyancy aid is connected by rope with net cage, and on buoyancy aid is bubbled through the water column, casing hangs in water, can be regulated the suspension degree of depth of net cage by buoyancy aid and rope.
Described net cage is preferably hexahedron net cage; Described hexahedron net cage height is not less than 1.5 meters, length and width freely adjusts as required (but all should not be less than 2 meters), there is net in net cage six face, mesh size is determined (preventing fish from gnawing Haloragidaceae Myriophyllum spicatum) by the size of the herbivorous fishes in the water body of place, be double-deck mesh bottom net cage: the spacing of two layers of mesh is 0.2 ~ 0.4m, wherein the mesh diameter of upper wire is 2 ~ 5cm, lower net bore dia 3 ~ 5mm, lower floor's mesh sheet covers the light ceramic that the thick particle diameter of 3 ~ 6cm is greater than 5mm.
Preferably, the method for described cage cultivation of myriophyllum spicatum, comprises the steps:
(1) in the water body of the depth of water more than 1.5 meters, lay above-mentioned suspension net cage, adopt buoyancy aid and rope to regulate and hang the degree of depth.
(2) in annual March, in net cage, Haloragidaceae Myriophyllum spicatum is inoculated.
(3) in net cage, put Plagiognathops microlepis or silver-colored silver xenocypris in a suitable place to breed, in order to scrape the sessile algae in food mesh sheet, maintain the water penetration of mesh.
(4) annual 4 ~ October, measure the change of water transparency month by month, hang the degree of depth according to the transparency degree of depth (20 centimetres of Sai Shi dish methods are measured) adjustment.
(5), during annual 10 ~ November, harvesting Haloragidaceae Myriophyllum spicatum (removing N, P from water body) of selecting a good opportunity, carries out net cage sterilization subsequently.
The method of the inoculation of the Haloragidaceae Myriophyllum spicatum described in step (2) is preferably the direct careless seedling of 0.5 ~ 0.7 meter long by band root and puts into net cage; Inoculum density be preferably 8 ~ 10 strains/square metre; Suspension degree of depth during inoculation, according to water transparency degree of depth decision at that time, makes plant more than 2/3 be positioned at more than light compensation depth (light compensation depth is about 1.5 ~ 2.5 times of the water transparency degree of depth).
The specification of the Plagiognathops microlepis described in step (3) or silver-colored silver xenocypris is preferably 10 ~ 12 centimetres; Breeding density is preferably 1 ~ 2 tail/m
3.
The suspension degree of depth described in step (4) preferably makes plant more than 1/2 ~ 2/3 be positioned at more than light compensation depth.
The present invention has the following advantages and effect relative to prior art tool:
(1) be fixed without the need to being tied up on mesh by Haloragidaceae Myriophyllum spicatum, labour intensity is low, is convenient to carry out large-scale promotion.
(2) adopt closed net cage as carrier, can prevent Haloragidaceae Myriophyllum spicatum from being gnawed by herbivorous fishes.
(3) Haloragidaceae Myriophyllum spicatum cultivation is in closed net cage, can resist the infringement of stormy waves plant.
(4) bottom net cage for Haloragidaceae Myriophyllum spicatum root system provides set field planting matrix, can plant strain growth be promoted.
