Abstract

A method for preparing the eelgrass turf includes such steps as collecting the ripe seeds of eelgrass, storing them in water, spreading mud on the bottom of water container, covering a braided object, wetting it, mixing said seeds with sand, spreading the mixture on said braided object, germinating, growing seedlings, filling clean water in said container for continuous growing, and transplanting in needle water.

Description

A kind of preparation method of eel grass turf
Technical field
The present invention relates to utilize waterplant to improve, beautify and administer water body environment, eutrophy algae type lake or water body and recover the aquatic vegetation field, more specifically relate to a kind of preparation method of eel grass turf.
Background technology
Aquatic vegetation especially submerged vegetation recovers to have become the key of body eutrophication improvement such as China lake, at present in the actual engineering that aquatic vegetation recovers, almost completely adopt a large amount of collection waterplant in the natural lake water body, utilize the zone that artificial individual plant or Dan Cong are planted in needs to recover aquatic vegetation then.There is following shortcoming in this method: the destruction of 1 pair of natural water body aquatic vegetation is huge, might cause decline and even the extinction of natural water body aquatic vegetation; 2 plantations and the required manpower of management process are huge, and inefficiency, when especially planting under heavy water state; 3 because plant is gathered, is transported and the influence of process such as plantation, and the vigor of waterplant reduces greatly, and plantation back surviving rate is low, is difficult to play the effect that improves water quality.Another method that often adopts at present aquatic vegetation is resumed work is that waterplant that can produce a large amount of seeds such as eel grass etc. are directly gathered seed, and being seeded in then needs to administer the zone growth of giving free rein to.Because the restriction of condition of water quality and the biological characteristics of waterplant itself, these seeds often seedling rate are very low, do not reach the effect of administering water body environment equally.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of eel grass turf, method is easy, and eel grass seedling rate and surviving rate height have solved the existing problem of water body aquatic vegetation recovery process effectively.
In order to achieve the above object, the present invention has adopted following technical scheme:
1. collect the mature fruit of eel grass in autumn and winter season, the fruit of collection places water to preserve;
2. evenly lay the mud of 8-12cm in the water container bottom;
3. on silt seam, cover the cloth of one deck crude substance quality, form the turf fixation layer;
Turf fixation layer water is moistening fully 4., do not want ponding;
5. eel grass seed and fine sand are mixed, evenly spreading is on cloth;
With container as for the light place, temperature is controlled at 15-25 ℃, keeps textile surface moistening;
7. when seed germination rate surpasses 80%, continue to keep moistening 2-4 week of textile surface, promote eel grass seedling root growth;
8. when the seedling base diameter surpasses 2mm greater than 1mm or width of blade, toward container in, slowly inject clear water, keep textile surface depth of water 1-2cm, and maintenance 1-2 week;
9. according to the real work needs, increase the depth of water and make the eel grass elongation growth, make eel grass grow into the water surface or change condition of water quality, make the eel grass turf adapt to the water condition of the last field planting of wanting;
10. the turf directly transplanting that growth is successful is in required water body zone.
The present invention compared with prior art has the following advantages and effect: 1 can realize the mass preparation of eel grass turf, avoids the destruction to the natural water body aquatic vegetation, also can avoid aquatic vegetation to recover the insufficient problem of seedling that often runs in the engineering; 2 are convenient to plantation, when reality is planted, according to the depth conditions and the used cloth quality of water body, can adopt the method field planting turf of direct laying, do not need underwater operation basically, the efficient height, and expense will reduce greatly simultaneously; 3 eel grass surviving rate height are especially when the eel grass that utilizes after the water that needs the recovery water body is anticipated; 4 eel grass turfs have the covering effect to the matrix of actual water body, help reducing the influence of water body matrix to water condition.
Embodiment
Concrete implementation step is as follows:
1. collect the mature fruit of eel grass (based on eel grass, the close thorn of other two kinds eel grass is relative seldom with wing eel grass quantity) in autumn and winter season, can in natural lake, collect, also can collect at the eel grass planting area.The fruit of collecting places water to preserve, and lets alone pericarp and rots naturally, discharges the heavy water of seed and preserves standby;
2. evenly lay the mud of 10cm in water container (different shape all can, general square container is convenient to management, surface-area is unsuitable too small, generally is convenient to operation greater than 25 * 25cm2) bottom;
3. cover the cloth of one deck crude substance quality (cotton, fiber crops, thin bamboo strips used for weaving, thin rattan etc.) on silt seam, cloth thickness between grid 2 * 2mm-10 * 10mm, forms the turf fixation layer less than 0.5cm;
4. ready turf fixation layer water is moistening fully, and obvious ponding does not appear in the surface;
5. standby eel grass seed and fine sand are mixed, evenly spreading is on cloth, and thickness is no more than 5mm, eel grass seed density 50-300 grain/square metre, density conference again causes unnecessary waste;
6. container is placed light to locate plentifully that (the natural lighting condition need not shaded, perhaps artificial lighting, intensity of illumination is greater than 1000lux, and every day, light application time was no less than 8 hours), temperature is controlled at 15-25 ℃, keep textile surface moistening fully, be advisable obvious ponding not occur;
7. when seed germination rate surpasses 80%, continue to keep moistening 2-4 week of textile surface, promote eel grass seedling root growth;
8. work as the seedling base diameter greater than 1mm, or width of blade surpasses 2mm, in container, slowly inject clear water, keep textile surface depth of water 1-2cm, and keep 1-2 week, increase the depth of water by the speed that increases 5cm weekly later on, the depth of water reaches can keep until turf behind the 20cm and develops successfully, the successful sign of turf development is an eel grass seedling healthy growth, well developed root system and going deep in the silt seam below the cloth, eel grass, cloth and be closely linked with silt seam;
9. according to the real work needs, estimate the depth of water and the transparency condition of planting area according to aquatic vegetation, the container that fills turf placed gradually impel the eel grass elongation growth under the corresponding depth condition, grow into the water surface up to eel grass, perhaps directly be used to support the eel grass turf, make the eel grass turf adapt to the water condition of the last field planting of wanting from the water planting of the aquatic vegetation planting area of estimating;
The successful turf of growth can directly transplanting in required water body zone.
