Description
Technical Field
The invention relates to the field of ecological restoration, in particular to a seedling raising method of tylophora.
Background
The seaweed bed is an ecosystem with extremely high productivity in the offshore area and has an important ecosystem service function. The seaweed bed not only provides the places for the marine aquatic animals to lay eggs, hatch, breed and grow, but also provides rich organic food sources for the marine aquatic animals. Therefore, the seaweed bed plays an important role in supporting the secondary production of the ecological system and plays a very key role in the aspects of aquatic animal resource maintenance, fishery sustainable development and the like. Meanwhile, the seaweed bed is an important 'blue carbon sink' in the coastal zone and plays an important ecological role in maintaining the global carbon cycle balance.
However, since the middle of the last century, the world-wide sea grass beds have been greatly destroyed by the influence of increased disturbance of human activities, global warming, extreme weather abuse, ocean acidification, and the like. The United nations environmental agency issues a survey report of the world map of seaweed for the distribution of seaweed in coastal regions of the world, and the content thereof is shownThe growth environment of the seaweed resources is increasingly deteriorated, and seaweed is extinct in some areas and endangers the survival of other marine organisms. The worldwide area of the distributed seaweed is about 177000km2About 26000km has been in the past 10 years2The ecological area of the seaweed disappears, and the reduction is 15 percent.
The Thalassia is sea weed of Thalassia of Amydaceae, widely distributed in tropical coastal areas of Pacific-Indian ocean, and is also a dominant species in tropical sea weed distribution areas of China. Like other kinds of seaweed beds, the grass beds in late decades are also greatly damaged by various influences, and the protection and recovery technology thereof is urgently developed.
The sea grass bed is mainly repaired by two methods, namely a transplanting method and a seed method. At present, the transplantation method is one of wide application and relatively mature technology. However, it also has inevitable drawbacks such as great damage to the donor seaweed bed, low genetic diversity of the seaweed bed after recovery, unstable ecological system of the seaweed bed, etc. In contrast, the recovery of the seaweed bed by the seeds can make up for the above deficiencies. The seaweed seeds have great potential contribution in keeping population structure and genetic diversity, maintaining seaweed beds, developing new patch grass beds and the like, and the time for repairing the disturbed seaweed beds by using the seeds is shorter than the time for repairing by simply using vegetative propagation. However, most seaweed seeds are lost due to hydrodynamic factors or feeding of marine organisms before germination and colonization by the traditional seed sowing method, and finally the survival rate is low.
Therefore, the seeds are collected in the ripening season of the Thalasia alata fruits, the seeds are enabled to germinate and grow into the seedlings of the Thalasia alata under the artificial controllable conditions, and then the seedlings are transplanted into the sea, so that the recovery efficiency of the sea bed of the Thalasia alata can be effectively improved. However, no report is found on how to improve the germination rate of the tylophora seeds and the growth speed of seedlings.

Test example 1 Effect of substrate on growth of seaweed
The calcareous sand (the main component is calcium carbonate) and the common sand (the main component is silicon dioxide) with different proportions are respectively tested as the substrate (passing through a 2mm sieve, the laying thickness is 2cm, the fertilizer addition amount is 0.5g/L, other sowing parameters and conditions are the same as those of the embodiment 1), the root length, the number of lateral roots and the tensile strength of seaweed after sowing for 21 days (the tensile strength is the minimum force required for pulling the seaweed seedlings from the sediments in a row, and the unit is Newton N), and the following table is shown:
TABLE 1 Effect of different substrate treatments on the growth of Talaroot
Therefore, the calcareous sand with the content of 50 percent or more can effectively promote the root development of the seaweed and enhance the tensile strength of the seaweed.
Test example 2 Effect of depth of implantation on seed Germination
The effect of different implantation depths on the germination of tylicapnos seeds was tested separately (other sowing parameters and conditions were the same as in example 1), and 10 seeds were used for each treatment, and the observation time was 7 days. Under otherwise identical conditions as in the examples, the data are as follows:
TABLE 2 Effect of depth of implantation on seed Germination
Therefore, when the seeds are planted, only the base parts of the seeds are buried into the sediments, and the cotyledon ends of the seeds are exposed, namely the planting depth is 1/2-3/4 of the height of the seeds, so that the improvement of the germination rate of the seeds is facilitated, and the root system development of the seeds is not influenced.
Test example 3 Effect of addition amount of controlled-Release Fertilizer on growth of seaweed seedlings
The influence of different controlled release fertilizer addition amounts on the growth of the tylicapnos seedlings is tested (other sowing parameters and conditions are the same as those in example 1), and the observation time is 60 days. Under otherwise identical conditions as in the examples, the data are as follows:
TABLE 3 influence of the addition of controlled release fertilizer on the growth of Tailaicao seedlings
Therefore, the fertilizing amount is too low, the content of nutrient elements is insufficient, and the growth of seaweed seedlings is inhibited; the fertilizing amount is too large, algae in water breed too fast, water transparency is affected, and photosynthesis of seaweed seedlings is further affected. The amount of the fertilizer is preferably 0.2-2.0 g/L.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
