Description
Technical Field
The invention relates to a laver culture device, in particular to an automatic lifting type laver culture device and a use method thereof, and belongs to the technical field of laver culture.
Background
The laver is one of the most popular marine vegetables, and is a large economic seaweed which has the largest culture area and the widest culture range in China at present. One thousand years ago, the coastal residents in China began to eat the laver and consciously proliferate the laver by using a reef cleaning mode, namely the earliest 'vegetable jar type cultivation method'. The method is used for the fifth and sixty years of the last century, and even certain islands in the Fujian coast still remain the ancient way; however, the method has poor controllability, the seedling source completely depends on the nature, and the laver yield and the popularization sea area are very limited. The modern laver cultivation technology is established in the sixties of the last century and mainly comprises three cultivation modes of a support column type cultivation mode, a semi-floating raft type cultivation mode and a full-floating raft type cultivation mode, so that the laver cultivation industry is rapidly developed. The 'support column type cultivation' is a mode that a wood pile or a bamboo pile is arranged as a support column in an intertidal zone or a sea area with proper water depth, and a laver net curtain is hung on the support column for cultivation, wherein the height of the net curtain can be randomly adjusted according to tide and net sunning requirements; the semi-floating raft type is a cultivation mode that the whole raft frame floats on the water surface when the tide rises, and sinks and stands on the mud flat when the tide falls; the two modes are that the rise and fall of tides are fully utilized, the laver net curtain is periodically exposed and dried to kill the diseases of the impurity algae, the healthy growth of the laver is ensured, and the method is the mainstream laver cultivation mode in China. However, both "semi-floating raft" and "column" cultivation methods are severely limited by tides and water depth. In recent years, the coastal areas, shallow seas and beaches suitable for cultivation are over developed and utilized, and the laver rot in the main production area is more serious due to the warming of climate and environmental change, which generally shows that the coastal cultivation area is more serious than the offshore cultivation area. Therefore, the development of laver cultivation to offshore deep water areas is a necessary way for sustainable development of laver industry in the future. The 'full floating raft type' cultivation mode can be implemented in a sea area which is far off the shore and deep in sea water, but the net curtain cannot be exposed, and the hybrid algae are easy to grow, so that the quality and the yield of the seedlings and the vegetables are influenced. Although the problem of the proliferation of miscellaneous algae such as enteromorpha and diatom can be solved to a certain extent by adopting a refrigeration net, a chemical killing mode and the like, the labor and material resources are consumed, the cost is increased, and the chemical treatment possibly causes negative influence on the environment.
In order to promote the development of laver cultivation to offshore deep water areas, new cultivation facilities and technologies are continuously changed. The invention patent CN103493722A discloses a device for dry dew of laver full-floating artificial cultivation and a using method thereof, the invention mainly adopts a trapezoidal float which is provided with a groove, when a net is aired, a bamboo pole supporting a laver curtain is turned into the groove of the trapezoidal float, the invention improves the defect that the laver curtain can not be dry dew in the traditional full-floating raft type cultivation technology, but the method of the invention needs to place the cultivation net curtains on the trapezoidal float one by one, which consumes manpower and is difficult to popularize in large area. The invention patent CN104488691A discloses a device for cultivating laver in deep water area and a using method thereof, which can solve the technical problem of laver screen, but the whole row of net curtains need to be turned over manually to realize the net drying, and because the whole net curtain is very heavy after laver algae grows up, the whole net curtain is very laborious to turn over manually and has great potential safety hazard.

10. A method for using the automatic lifting type laver culturing device according to any one of claims 1 to 9, which comprises the following steps:
(1) rising: tying two long edges of the laver culture net on two adjacent brackets, and respectively tying two short edges on two upper-layer pipe fittings; according to the growth condition, climate and sea condition of the laver algae, managers issue control commands on the shore, the control commands are transmitted to an offshore electric control system through a wireless network, a vent valve is controlled to be opened, air enters lower-layer pipe fittings through a vent pipe, a bidirectional water pump is controlled to be opened at the same time, seawater in the lower-layer pipe fittings is pumped into the sea through a water pipe, when the water-leaving distance of a laver culture net meets the requirement, the bidirectional water pump is stopped, and the vent valve is closed; the distance between the laver culture net and the water surface is the rising height, the proper height is adjusted according to the length of the algae, and the laver grows to 15-20cm and then is collected; at this time, the laver culturing net is exposed to the air to be sunned;
(2) and (3) descending: after the net airing time meets the requirement, a manager issues a control command on the shore, the control command is transmitted to an offshore electric control system through a wireless network, a bidirectional water pump is started, the water inlet and outlet directions of the water pump are adjusted, at the moment, seawater is injected into a lower-layer pipe fitting from the sea by the water pump through a water pipe, a vent valve is controlled to be opened, air in the lower-layer pipe fitting is discharged through a vent pipe, and after an upper-layer pipe fitting falls to the water surface, the bidirectional water pump is stopped, and the vent valve is closed; at this time, the laver cultivation net attached to the upper pipe is immersed in seawater and grows normally; when the light is too strong and the transparency is too high, the living water layer of the laver net is properly reduced by increasing the water storage amount in the lower layer pipe fitting, so that the adverse effect of long-time high light stress on the growth and the quality of the algae is avoided.
