Abstract
The invention has the following beneficial effects: by artificial collection of ottelia acuminate seeds, artificial acceleration of seed germination, artificial seedling culture and field planting, population is restored through artificial intervention to avoid damages to ottelia acuminate colonies caused by field environment deterioration; the vegetation in the lakes wherein ottelia acuminate is located is restored while restoring ottelia acuminate, so that the population is richer; and besides, a restoring method disclosed by the invention is also suitable for restoring colonies of other submerged plants through proper adjustment.
Description
Technical field
The present invention relates to the method for recovering vegetation of a kind of lakeside band submerged plant.
Background technology
The edible seaweed flower is a kind of submerged plant, mainly is distributed in the one band water body in lake of China southwest, and the edible seaweed flower evolves to unisexual flower by hermaphrodite flower, and phenomenons such as stamen and style decreased number have scientific value to the evolution of studying its section's genus.Simultaneously form polytropy of population and mutability on research ecological factor and the morphogenesis dependent interaction also highly significant.In addition, the edible seaweed flower also makes it have high ornamental value and use value with its unique outward appearance and delicious mouthfeel.But in recent years because water pollution and artificial destruction, the edible seaweed flower group in the lake degenerates serious, some in addition disappear, for protecting a southwestern band lake vegetation population, be badly in need of recovering the edible seaweed flower, so that band forms stable submerged plant group in the lakeside.
Summary of the invention
For solving the serious problem of edible seaweed flower group's degeneration, the present invention provides a kind of edible seaweed flower recovering method of artificial interference, and this method is mainly accomplished the recovery of edible seaweed flower group through key steps such as biological engineering's inputs.
Be to realize above-mentioned purpose, edible seaweed flower of the present invention group recovering method mainly may further comprise the steps: 1, seed collection storage, 2, seed germination, 3, grow seedlings and 4, four steps of open-air field planting.
Further, the storage of said step 1 seed collection is specially: collect the edible seaweed flowers fruit, in 4 ± 1 ℃ of temperature, humidity>preserve under 80% the condition.
Further, the seed germination of said step 2 is specially: the fruit of refrigeration is taken out, remove pericarp, seed is taken out, and place 60 mesh sieves, use water temperature < 30 ℃ water flushing 15-30min; Then, seed is placed under temperature 25-30 ℃, the condition of illumination 1000-5000Lux, Light To Dark Ratio 24h:0h to 12h:12h, impel its fast-germination or sprout.
Further, the time ratio lake nature germination period that begins of said seed germination shifts to an earlier date and carries out the 1-2 month.
Further, what said step 3 was grown seedlings is specially: a, will plant bud and pack into and be equipped with in the container of stickiness lake mud, container is square or circular, and its diameter/length of side is no more than 5cm, highly is 5-6cm;
B, the container that kind of bud will be housed are put into on-swimmer's pool, and water temperature is controlled between 20-30 ℃, and the depth of water is 15-20cm during beginning;
C, according to actual plant height plantation demand: weak wind district requires plant height 20-30cm, and the wave is high, and the district requires plant height 80-120cm, treats to finish to grow seedlings after seedling reaches the requirement plant height.
Further, also comprise among the said step b along with growth of seedlings, can corresponding raising pool inner water dark, but the depth of water should be controlled at above in the height of seedling 3-5cm scope,
Further, said step 4 field planting is specially: 1) in the more weak zone of wind: edible seaweed flower seedling 1-3 strain is fixed in the clay clod, and wraps clod with bundle, expose seedling, drop in the water; 2) in the bigger zone of stormy waves, first edible seaweed flower seedling is wrapped in the clay clod, again with clay clod plug to hollow brick, drop in the water then.
Further, said hollow brick for fire ball clay through can nature in water body after a period of time fragmentation fall, the clay clod that function of water body is not had an influence is fired and is formed, its bottom squarely or circle, the length of side/diameter is 10-20cm, thick 2-5cm; Highly be not less than 8cm.
Further, the edible seaweed seeds of flowering plants is planted spacing 0.5-1m in second of said mode of planting kind.
The present invention is through artificially collecting the edible seaweed flower seed, the artificial mode that promotes seed germination, artificial breeding and open-air field planting, under manual intervention to carrying out repopulate, the infringement that because wild environment worsens edible seaweed flower group is brought to avoid.And when recovering the edible seaweed flower, its place lacustrine plant vegetation is restored, the crowd plants abundanter.In addition, disclosed recovering method is suitably adjusted among the present invention, is applicable to that also the group of other submerged plants recovers.
Embodiment
Disclosed edible seaweed spends group's recovering method to be primarily aimed at the restoration and reconstruction of inland sea, region, lakeside cauliflower group among the present invention.Comprise 1, the seed collection storage, 2, seed germination, 3, grow seedlings and 4, four steps of open-air field planting.Each step is specially: 1, seed storage: collect edible seaweed flowers fruit (seed), in 4 ± 1 ℃ of temperature, humidity>preserve under 80% the condition.2, seed germination: the fruit of refrigeration is taken out, remove pericarp, seed is taken out, and place 60 mesh sieves, the flushing 15-30min that discharges water, < 30 ℃ of water temperatures; Then; Seed placed impel its fast-germination under temperature 25-30 ℃, the condition of illumination 1000-5000Lux, Light To Dark Ratio 24h:0 h to 12 h:12 h or sprout, use above-mentioned germination method can improve the germination rate of seed and can effectively control the germination period of seed.In addition, time of beginning of seed germination work should shift to an earlier date than lake nature germination period and carries out the 1-2 month.3, grow seedlings: a, will plant bud and pack into and be equipped with in the container of stickiness lake mud, container should not surpass 5cm with square or round diameter/length of side, and height 5-6cm is advisable; B, the container that kind of bud will be housed are put into on-swimmer's pool, and water temperature is controlled between 20-30 ℃, and the depth of water is advisable with 15-20cm during beginning, and along with growth of seedlings, should corresponding raising pool inner water dark, but, the depth of water should be controlled at above in the height of seedling 3-5cm scope; C, according to actual plant height plantation demand: weak wind district requires plant height 20-30cm, and the wave is high, and the district requires plant height 80-120cm, treats to finish to grow seedlings after seedling reaches standard.4, field planting: because the edible seaweed flower becomes seedling bigger, receive the influence of stormy waves easily, its field planting is difficulty, and this method is taked different field planting methods in different zones.1) in the more weak zone of wind: edible seaweed flower seedling 1-3 strain is fixed in the clay clod, and wraps clod, expose seedling, drop in the water with bundle; 2) in the bigger zone of stormy waves, first edible seaweed flower seedling is wrapped in the clay clod, again with clay clod plug to hollow brick, drop in the water then.Hollow brick is by environmentally friendly, promptly fires ball clay through in water body, can the nature fragmentation falling after a period of time, and the clay clod that function of water body is not had an influence is fired and formed bottom squarely or circle, the length of side/diameter 10-20cm, thickness 2-5cm; The hollow brick height is not less than 8cm, and the edible seaweed seeds of flowering plants is planted spacing 0.5-1m.Annotate: the mode of the inapplicable direct throwing of this distance.
