Description
Technical Field
The invention relates to a submerged plant community restoration and reconstruction technology. More particularly, the present invention relates to a method for rapidly recovering a phoma longifolia population.
Background
Submerged plants are the most basic and important primary producers of water ecosystem, play the bait, inhabit and breed the place for part of fishes, benthonic animals, zooplankton and the like in the water body, and have important ecological significance in maintaining the structural stability and species diversity of the water ecosystem. In addition, the submerged plant also plays an irreplaceable role in the aspects of water quality purification, landscape improvement, improvement of water habitat conditions and the like. However, due to the enhancement of human activities, water body pollution such as the acceleration of eutrophication process, the rapid decrease of transparency and the like is caused, submerged plants are degenerated and disappear, and a series of water ecological environment problems such as water quality deterioration, frequent occurrence of water bloom, water ecosystem damage and the like are caused. Therefore, the restoration and reconstruction of submerged plant communities are considered to be one of the important means for the damaged water ecosystem to carry out water body restoration and biodiversity restoration.
The selection of the restoring species is one of the most major technical problems in restoration and reconstruction of submerged plant communities. Potamogeton lucens Morong is a perennial submerged herb of Potamogeton genus of Potamogeton family of ophthalmocaceae, and is distributed in irrigation canals, ponds, rivers and the like in provinces of northeast, east and west of China and in Yunnan equal places, and belongs to native submerged plants in China. The potamogeton glabra has a rhizome, the shape of the rhizome is similar to that of a root, the tuber grows below a soil layer, obvious nodes and internodes are formed, the nodes have redifferentiation capacity, and terminal buds are formed. The top bud or node of the rhizome generates root system, and new plant individual is cloned and generated. The rhizomes store abundant nutrients and can survive for one to many years. Therefore, the potamogeton phocarpus is an excellent water ecological restoration pioneer species based on the biological characteristic analysis and the field distribution characteristic analysis of the potamogeton phocarpus.
The planting method is also the most important technical problem in the restoration and reconstruction of submerged plant communities. Under the general condition, the ecological balance of the damaged water body is broken, and the submerged plant community is difficult to restore through a natural mechanism, so that most of submerged plants for restoring the water environment are artificially and auxiliarily planted. The submerged plant planting methods currently used include a cutting method, a throw-out method and a sowing method. The insertion planting method is to directly insert the root base of the plant into soft substrate mud at a low water level, and has the defects of high labor intensity and operation difficulty, and limited application by water depth, substrate softness and properties. The throwing planting method is that soft clay, gauze, plastic cloth and other materials are used to tie the root base of the plant and then the plant is directly thrown and planted under the action of gravity, and the defects are that the wrapping soft clay or clay is easy to break away and run off, and the tied or wrapped plant has limitation on the plant growth, so that the plant survival rate is low and the plant growth state is poor. The direct seeding method has the disadvantages of scattering of seeds with water, lowest survival rate after germination, influence of various environmental factors on seedling growth, long recovery period and the like.
The seeds of the potamogeton glabra have thick seed coats, are not easy to germinate in a natural state, and are not easy to collect in large batches. Therefore, there is a need to develop a restoration technology of pholiota nameko population, which is low in cost, easy to operate and high in survival rate.

3.5 treating with spirogyra. Spraying 25% triphenyltin acetate WP with the dosage of 300g/hm 2 And does not drain water to the outside 30 days after the application.
Step 4, population monitoring and biological quantity control
When the cover degree of the submerged vegetation reaches more than 40 percent, a grass type clear water body can be constructed; when the vegetation cover degree is 40% -70%, the grass-type clear water body can be maintained; when the coverage is more than 70%, the biological quantity of the eyebright herb population must be controlled, and the grass carp feeding or manual harvesting can be properly increased.
Control group 1-bamboo pole transplanting method
In middle 5 th of 2021, the same water quality and environment was the same when the collybia glabra was planted in the adjacent pools of example 1 by bamboo-cutting planting at the same time of seed throwing. The branch breaking treatment method of S1.2 propagule treatment in the embodiment 1 is adopted, 8 branches are bundled into one bundle, and the base of the bundle is clamped by a bamboo pole until the sludge is formed, so that planting is completed. 8 branches per hole were cut by the same method as 1.3 in example 1, and the planting density was 18 holes per square meter. The remaining management method is the same as in step S3 and step S4 of embodiment 1.
Control group 2-mud wrapping throwing planting method
In the middle 5 th of the 2021 year, the potamogeton glaucophyllus is planted in the adjacent water pools of the embodiment 1 by adopting a mud wrapping and throwing planting method at the same time of throwing the seeds, and the water quality and the environment are the same. The method for treating broken branches of S1.2 propagules in example 1 is adopted, 8 broken branches are wrapped by pond sludge, and then wrapped by non-woven fabrics and directly thrown into water to finish planting. 8 branches per hole were cut by the same method as 1.3 in example 1, and the planting density was 18 holes per square meter. The remaining management method is the same as step S3 and step S4 of example 1.
After 1 month of seed throwing, the survival rate, plant height and population coverage of the euglena phocarpoides of example 1, control example 1 and control group 2 were investigated as shown in table 1. The result shows that after the method of the embodiment 1 of the invention is used for 1 month after seed polishing, the survival rate of the planted potamogeton lucidus reaches 98%, the growth height of the plant exceeds 60cm, the vegetation coverage reaches 50%, and the purpose of quickly recovering the potamogeton lucidus population is realized. The comprehensive consideration of the labor condition for recovering the water surface of unit area shows that the recovery effect of the pholiota nameko population is obviously superior to that of the bamboo pole inserting planting method and the mud wrapping throwing planting method.
