Accompanying drawing explanation
Fig. 1 is the structural representation cultivating principle in the embodiment of the present invention.
Number in the figure implication: 1-beach; 11-beach surface; 2-separation net structure; 3-catch net; 4-hangs razor clam.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, to hang razor clam mudflat aquaculture method, before razor clam seed is hung in input, be equipped with one deck in beach lower face and be excessively drilled to separation net structure 2 in beach for the razor clam seed that prevents from hanging, in the present embodiment, separation net structure is polythene material, the structure of this material is comparatively stable, can be embedded in beach for a long time, can repeatedly use, this separation net structure 2 is highly 30-50cm setting apart from beach surperficial 11, throwing in hangs lays the catch net 3 of the razor clam seed prey that prevents from hanging after razor clam seed at separation net superstructure, the aperture of described catch net 3 is greater than separation net structure 2 and arranges, in the present embodiment, the aperture of separation net structure 2 is between 10-20 order, aperture within the scope of this razor clam 4 that can prevent from hanging continues down to be drilled in darker beach, the aperture of catch net is between 3-5 order, the predation to razor clam seed of hanging can be prevented.
Point four groups of experiments in this enforcement, be respectively separation net structure distance beach surface for 30cm, 40cm, 50cm and without under separation net configuration state, often group cultivates in units of 1 mu, at the beginning of 3 months, input cultivation is carried out to razor clam seed of hanging, the injected volume of every mu of razor clam seed of hanging is 220 jin, hang the length of razor clam seed at about 2CM, and the quantity of per jin razor clam seed of hanging is about 1500, gets the observation that a certain amount of razor clam sample of hanging carries out upgrowth situation respectively when May and August to each group.Show that razor clam of hanging is in different separation net constructional depth and without growing state list off the net;
Adopt catch season for above-mentioned four groups experiment razor clams of hanging carry out adopting catching, draw following data;
Can be learnt by above-mentioned data:
1, separation net structure distance beach surface be in the data of 30cm, and because mud layer is more shallow, razor clam of hanging be horizontal growth, and the size of razor clam of hanging is too late without in net situation, but due to its mud layer more shallow, be convenient to adopt and catch, its per mu yield is greater than the situation that nothing is netted.
2, separation net structure distance beach surface is in the data of 40cm, mud layer is moderate, the size of razor clam of hanging is homogeneous, razor clam " stand-type " of hanging grows, there is larger growth size, adopt and catch conveniently, when being 30cm relative to separation net constructional depth, razor clam of hanging has larger size and has higher output.
3, separation net structure distance beach surface is in the data of 50cm, mud layer is moderate, the size of razor clam of hanging is homogeneous, razor clam " stand-type " of hanging grows, and has larger growth size, adopts and catches conveniently, when being 40cm relative to separation net constructional depth, razor clam of hanging have slightly compared with size and there is higher output, namely when have separation net structure and distance beach surface 50cm, the cultivation of razor clam of hanging has maximized benefit.
