Detailed Description
For a clearer understanding of the technical solutions in the present application, the relevant contents of plants grown in desert will be described first. The difficulty in growing plants in deserts is that the water retention of the sand grains is too low, for example, by pouring water into the soil, which can absorb the water, but by pouring water into the desert, the water evaporates quickly, which results in the plants not getting enough water.
The second reason is transpiration at high temperature, and the plants need to lower the surface temperature by means of water evaporation, and are easily heated to death when the water content is insufficient. The third reason is salinization, and the evaporation of a large amount of water can increase calcium and magnesium compounds in sand grains, thus further deteriorating the environment.
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an ecological restoration system for wind prevention and sand fixation disclosed in an embodiment of the present application is composed of a moisture retention bottle 11, a water diversion pipeline 12, a blasting patch 13, a control pipeline 14, a branch control line 15, a water supply pipeline 16, a main control line 17, and the like, wherein the moisture retention bottle 11 is used for buying into a sand grain layer and wrapping the root system of a plant to form a relatively closed environment for providing moisture to the root system of the plant.
The first end of branch water pipe 12 stretches into in moisture keeps bottle 11, and the effect is to pouring into moisture in the moisture keeps bottle 11, and the second end and the water supply pipe 16 of branch water pipe 12 are connected, and water supply pipe 16 is used for providing moisture to branch water pipe 12, and a water supply pipe 16 can be connected with many branch water pipe 12 simultaneously, and like this at the watering in-process, the staff is connected the water source with water supply pipe 16, just can irrigate many plants simultaneously.
The blasting patch 13 is adhered to the outer wall of the moisture holding bottle 11, and serves to break the moisture holding bottle 11, it is understood that the volume of the moisture holding bottle 11 is fixed, the root system of the plant is spread around after the plant survives to search for nutrition and moisture, and the moisture holding bottle 11 limits the root system of the plant to a small range if the moisture holding bottle 11 is not removed.
As plants grow, they die from getting nutrients and water, because the ultimate goal of tree planting in deserts is to allow the plants to survive themselves, which, if supplemented with water, can overburden the locally limited water resources.
The blasting patch 13 is detonated through the branch control line 15, a first end of the branch control line 15 is connected with the blasting patch 13, a second end of the branch control line 15 extends into the control pipeline 14 and extends out from a second end of the control pipeline 14 and is connected with the main control line 17, a connector 171 is arranged on the first end and/or the second end of the main control line 17, and the connector 171 is used for connecting other main control lines 17 or detonators, please refer to fig. 3.
The control pipe 14 is fixed to the shunt pipe 12, and in some possible implementations, the control pipe 14 is integrally formed with the shunt pipe 12. In addition, the control pipe 14 can also be used as a detection pipe, for example, a humidity sensor can be inserted into the moisture holding bottle 11 through the control pipe 14 to detect the moisture content in the moisture holding bottle 11, so as to provide data support for the next irrigation.
After the blasting patch 13 is detonated, the water distribution pipe 12 and the control pipe 14 are withdrawn from the sand layer for recovery, or are irrigated for a period of time and then recovered.
The moisture-holding bottles 11 are arranged at intervals along the water supply pipeline 16, that is, the moisture-holding bottles 11 can be disposed in the covering area of the water supply pipeline 16, and the water distribution pipeline 12 can cover a plurality of moisture-holding bottles 11 at the same time, for example, when several plants are planted at the same place.
Overall speaking, the ecological remediation system for preventing wind and fixing sand disclosed in the embodiment of the application uses the moisture retention bottle 11 to provide a relatively stable growth environment for the earlier stage growth of plants, can effectively reduce the high death rate of the plants in the earlier stage after transplantation, and can provide enough moisture for the plants by intermittently replenishing water to the moisture retention bottle 11, and meanwhile, the moisture retention bottle 11 also effectively prevents the evaporation of the moisture, and the utilization rate of the moisture is improved.
After the plants are transplanted, the development of root systems is finished, and the plants have certain adaptability to the surrounding environment, and at the moment, the root systems of the plants can spread to the surrounding environment by selectively cracking the water retaining bottles 11. The method can effectively improve the survival rate of the plants, and can effectively fix the sand grains along with the increase of the number of the plants and the coverage area, thereby achieving the effect of inhibiting desertification.
As a specific implementation mode of the ecological restoration system for wind prevention and sand fixation, the water retaining bottle 11 is made of glass, harmful substances cannot be generated in the decomposition process of the glass, the influence on the environment is very small, the glass is easy to break in the blasting process, the generated cracks can also spread, and when a plant root system meets glass fragments with cracks, the glass fragments can pass through the plant root system more easily.
Referring to fig. 1, as a specific embodiment of the ecological restoration system for wind prevention and sand fixation provided by the application, a plurality of blasting patches 13 are uniformly distributed on the outer wall of the moisture holding bottle 11, so that the moisture holding bottle 11 can be broken as much as possible, and the plant root system can smoothly spread to the surroundings.
Referring to fig. 1 and fig. 2, as a specific embodiment of the ecological restoration system for wind prevention and sand fixation provided by the application, a fixing ring 111 is provided on the moisture retention bottle 11, and the fixing ring 111 is used for temporarily fixing the water diversion pipeline 12, so as to prevent the retention bottle 11 and the water diversion pipeline 12 from being dislocated during the process of burying the moisture retention bottle 11.
Before the landfill, the first end of the water distribution pipe 12 is first inserted into the moisture retention bottle 11 after passing through the fixing ring 111, and then the water distribution pipe 12 is inserted.
Referring to fig. 1, as a specific embodiment of the ecological restoration system for wind prevention and sand fixation provided by the application, a flow meter 121 is additionally installed on the water diversion pipeline 12, and the flow meter 121 is used for controlling the amount of water flowing into the water retention bottle 11.

In other possible implementations, a communication chip is installed in the flow meter 121, and the communication chip communicates with the upper computer and executes the communication according to the received data.
It will be appreciated that when water is supplied to the plurality of branch pipes 12 using the water supply pipe 16, the branch pipe 12 located in front will receive more water, and obviously, this will cause a part of the water in the water holding bottle 11 to overflow and a part of the water in the water holding bottle 11 to be insufficient, which will directly affect the survival rate of the plant and will also cause waste of water resources.
After the flow meter 121 is added, the amount of water flowing into the water holding bottle 11 can be controlled, and the flow meter 121 is automatically closed when the flow rate meets the requirement.
Referring to fig. 2, as a specific embodiment of the ecological restoration system for wind prevention and sand fixation provided by the application, a first end of the control pipeline 14 extends into the moisture holding bottle 11, and a second end of the branch control line 15 extends into the control pipeline 14 from a side wall of the control pipeline 14 and extends out from a second end of the control pipeline 14.
This is equivalent to a channel between the moisture retention bottle 11 and the ground, and the staff can collect data (such as humidity) in the moisture retention bottle 11 through the channel, so as to provide reference data for later detonation and irrigation.
Referring to fig. 4 and 5, as a specific embodiment of the ecological restoration system for wind prevention and sand fixation provided by the application, an intercepting barrier 2 is added around the moisture retention bottle 11, the intercepting barrier 2 is composed of a beam 21, punctures 22, puffs 23 and the like, specifically, the number of the punctures 22 is multiple and the punctures 22 are arranged on the beam 21 at intervals, gaps exist between adjacent punctures 22, and the puffs 23 are directly fixed on the beam 21.
When the sand fixing device is used, the puncture 22 is directly inserted into a sand layer, the beam 21 and the fluffy body 23 are left outside the sand layer, the puncture 22 can reduce the flowability of the sand layer, and the fluffy body 23 can intercept flowing sand particles to play a role in sand fixing.
In some possible implementations, the puffs 23 may be branches and hay, and then tied to the beam 21 with iron wire.
The moisture retaining bottle 11 is surrounded by a plurality of cross members 21, and the cross members 21 surround the moisture retaining bottle 11 to reduce the flow of the sand layer around the moisture retaining bottle 11.
Further, referring to fig. 6, the cross beam 21 includes a plurality of sub-cross beams 211 hinged in sequence, so that the shape of the cross beam 21 can be adjusted according to the use requirement, and different use requirements can be met.
