Description
Technical field
The present invention relates to a kind of outdoor red duckweed protecting method.
Background technology
Red duckweed has another name called Azolla imbricata, is a kind of fern floating plant, and Anabaena (anabena) symbiosis often and in blue-green algae, Anabaena can fix the nitrogen in air.Therefore, it as the Fine green manure of the crops such as paddy rice, also can be made the feed of fish and domestic animal, be widely used.But because self not easily forms sporocarp, red duckweed variety source is preserved based on its trophosome, the method that we adopt at present is that solarium's cultivation preservation, hot-house culture preservation and Shoot-tip Culture cultivation are preserved.Wherein the most general, simple to operate, to environmental requirement not high be that the outdoor solarium of red duckweed cultivates and preserves, but because outdoor environment is complicated, the growth of red duckweed, purity are easily subject to the impact of extraneous factor, relatively more outstanding is exactly that the Litter-falls such as various insect, branch are easily fallen in red duckweed culture vessel, in addition, because natural rainy spell and rainfall are all uncertain, excessive rainwater can wash away red duckweed from culture vessel, thus adds workload and the conservation cost of manual maintenance.In order to more effectively improve red duckweed resource conservation quality, reduce the amount of labour, reduce conservation cost, the research and development of conservation device have very important meaning.
Summary of the invention
The object of this invention is to provide a kind of outdoor conservation device of red duckweed of practicality, minimizing insect pest and foreign material, on the impact of red duckweed normal growth, effectively control the water yield in red duckweed culture apparatus, prevent spill-over out, reduce the outdoor red duckweed conservation amount of labour and conservation cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Fig. 1 ~ 2, a kind of outdoor red duckweed conservation device, comprise incubator 1, be placed on fly net 2 above incubator case mouth and water level control pipe 3, described incubator box body sidewall is provided with the through hole 4 passed for water level control pipe 3, described water level control pipe one openend is stretched in incubator bottom culture fluid, and the other end extends to outside casing through through hole.
Described water level control pipe 3 can have several, during installation, according to the quantity of the setting of water level control pipe 3, equal number through hole 4 can be set on incubator 1 casing, the aperture of this through hole 4 can slightly larger than water level control pipe 3, described through hole 4 is positioned at incubator sidewall middle and upper part, namely near the opening part at incubator 1 top.
Described incubator can be column shape container, and the ratio of described incubator 1 base diameter and box height is 2.5:1.But aspect ratio is lower, the red duckweed in incubator 1 can be made like this to obtain good daylighting.
Described fly net 2 forms network structure by steel wire right-angled intersection, and described netted aperture is of a size of 1.5 ~ 2mm.
This fly net 2 can prevent Litter-fall, insect, mosquito etc. from falling in incubator, adopts stainless steel wire then can prevent fly net from making moist and gets rusty.
Described water level control pipe 3 is inverted U and two openends are different to distance from top, and it is longer than the openend extended to outside casing with the distance at top that described water level control pipe 3 stretches into the openend in culture fluid, and water level control pipe 3 material can be glass or lucite.
When rain or when watering, culture fluid in incubator 1 goes up, if do not arrange water level controller 3, then red duckweed can be taken out of when water spill-over goes out incubator 1, cause the inconvenience of management maintenance, utilize the water level controller 3 in the present invention, when water level reaches two side through hole 3, unnecessary water then can flow out from U-shaped water level controller 3, can not cause the phenomenon that red duckweed is overflowed.
Second technical scheme of the present invention is a kind of outdoor red duckweed protecting method: comprise outdoor red duckweed conservation device.
