Description

Technical Field

[0001] The invention belongs to the technical field of slope protection plant planting, and in particular relates to a method for planting riverbank slope protection plants and restoring their communities. Background Art

[0002] The riparian zone, also known as the riverbank zone, water level fluctuation zone, etc., is a special area where parts of the land are periodically flooded and exposed to the water due to seasonal water level fluctuations in rivers, lakes, reservoirs, etc. The riparian zone plays an important role in maintaining the balance of the embankment ecosystem and protecting reservoirs, lakes and river water bodies. The riparian zone vegetation has a certain interception and filtering function on the pollution from the reservoir bank. A considerable part of the nitrogen and phosphorus carried by the surface runoff is digested and absorbed by the vegetation to prevent entering the water body. At the same time, the vegetation roots can prevent the erosion of the river bank by the water flow and reduce the amount of sediment deposition in the river.

[0003] Due to the current serious factors of soil erosion, the soil in the riverbank zone has seriously degraded. The matrix is ​​mainly coarse sand and gravel, which not only has extremely poor water retention performance but also low soil fertility. When the staff plant vegetation on the riverbank slope to consolidate the soil, it is not convenient for the vegetation to grow, which reduces the growth efficiency of the vegetation and thus reduces the strengthening effect of the staff planting vegetation on the riverbank slope. Therefore, a method for planting riverbank slope protection plants and restoring communities is proposed. Summary of the invention

[0004] The object of the present invention is to provide a method for planting riverbank slope protection plants and restoring communities to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A method for planting riverbank slope protection plants and restoring communities, comprising:

[0007] Step 1: Investigate the soil conditions of the river bank slope protection;

[0008] Step 2: Turn over the soil on the river bank slope protection;

[0009] Step 3: Adjust the pH value of the soil on the river bank slope protection;

[0010] Step 4: Mix the fermented and decomposed agricultural and forestry waste in proportion and add it to the river bank slope protection;

[0011] Step 5: Plant green manure plants. When the green manure crops grow to a certain stage, cut off their stems and leaves and turn them into the soil so that their organic matter can decompose in the soil and release nutrients.

[0012] Preferably, the items investigated on the soil condition of the river bank slope protection are soil loss, gravel above the soil and soil pH.

[0013] Through the setting of the above technical scheme, the role of investigating the soil conditions of the river bank slope protection is:

[0014] It allows the staff to know the soil conditions of the river bank slope protection, so that the staff can make targeted improvements to the soil quality of the river bank slope protection, thereby improving the staff's efficiency in optimizing and improving the soil of the river bank slope protection.

[0015] Preferably, the soil turning operation is to plow and turn the soil on the river bank slope protection, turn out the soil at the bottom and mix it with the soil above, and clean up the gravel on the river bank slope protection.

[0016] Through the setting of the above technical scheme, the effect of turning over the river bank slope protection soil is utilized:

[0017] Tilling the soil can make it loose and increase the porosity in the soil, which is conducive to receiving and storing rainwater and improving the soil's water storage capacity. Soil that has not been tilled for a long time is prone to forming a plow bottom layer, which makes the soil compact and is not conducive to the growth of plant roots. Tilling the soil can effectively break the plow bottom layer, deepen the tillage layer, and provide a wider growth space for plant roots. Tilling the soil can improve the aeration of the soil, making it difficult for toxic gases in the soil to accumulate, while providing more air to the roots and promoting the activities of aerobic microorganisms. These microorganisms will release more nutrients, such as nitrogen, phosphorus, potassium, etc., in the process of decomposing organic matter, thereby improving the fertility of the soil. Tilling the soil can also promote the mineralization of organic matter in the soil, converting organic matter into fast-acting nutrients that are easily absorbed and utilized by plants, such as fast-acting nitrogen and fast-acting phosphorus.

[0018] Preferably, the pH adjusting substances are quicklime, slaked lime, sulfur powder and aluminum sulfate, and the crushed agricultural and forestry wastes include sawdust and crushed wheat straw.

[0019] Through the setting of the above technical scheme, the pH value of the river bank slope protection soil is regulated:

[0020] Adjusting soil pH can improve soil physical properties, such as soil structure, air permeability and water retention. Appropriate soil pH is conducive to the formation of soil aggregate structure, enhancing soil air permeability and water permeability, thereby improving soil water and fertilizer retention capacity; adjusting soil pH can release some nutrients fixed by the soil, such as phosphorus, potassium, calcium, magnesium, etc., increase the effectiveness of these nutrients, and thus improve soil fertility; appropriate soil pH can stimulate the activity of soil microorganisms, promote the decomposition of organic matter and the release of nutrients by microorganisms, and the activity of microorganisms not only helps to improve soil fertility, but also improves soil structure and enhances soil resistance to erosion;

[0021] In addition, by adding decomposed and crushed agricultural and forestry waste to the river bank slope protection, the filling soil during transplanting contains decomposed and crushed agricultural and forestry waste, which can not only improve the soil structure of the river bank zone which is mainly composed of coarse sand and gravel, but also provide the nutrients needed for plant growth in the later stage, while also avoiding the influx of elements such as N, P, and K into the river due to artificial fertilization.

[0022] Preferably, the green manure plants are astragalus, alfalfa and sweet clover.

[0023] Through the setting of the above technical scheme, the role of planting green manure plants is utilized:

[0024] During the vegetation growth period, green manure crops can absorb a large amount of nutrients and directly cover the soil surface for return to the field after the growth is completed. After the organic matter of green manure crops is decomposed, it can provide nutrients to the soil, improve the soil environment and increase soil fertility.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The role of investigating the soil conditions of river bank slope protection is as follows:

[0027] It allows the staff to know the soil conditions of the river bank slope protection, so that the staff can make targeted improvements to the soil quality of the river bank slope protection, thereby improving the staff's efficiency in optimizing and improving the soil of the river bank slope protection.

[0028] The effects of turning over the river bank slope protection soil:

[0029] Tilling the soil can make it loose and increase the porosity in the soil, which is conducive to receiving and storing rainwater and improving the soil's water storage capacity. Soil that has not been tilled for a long time is prone to forming a plow bottom layer, which makes the soil compact and is not conducive to the growth of plant roots. Tilling the soil can effectively break the plow bottom layer, deepen the tillage layer, and provide a wider growth space for plant roots. Tilling the soil can improve the aeration of the soil, making it difficult for toxic gases in the soil to accumulate, while providing more air to the roots and promoting the activities of aerobic microorganisms. These microorganisms will release more nutrients, such as nitrogen, phosphorus, potassium, etc., in the process of decomposing organic matter, thereby improving the fertility of the soil. Tilling the soil can also promote the mineralization of organic matter in the soil, converting organic matter into fast-acting nutrients that are easily absorbed and utilized by plants, such as fast-acting nitrogen and fast-acting phosphorus.

[0030] By regulating the pH value of river bank slope protection soil:

[0031] Adjusting the soil pH can improve the physical properties of the soil, such as soil structure, air permeability and water retention. Appropriate soil pH is conducive to the formation of soil aggregate structure, enhancing soil air permeability and water permeability, thereby improving the soil's ability to retain water and fertilizer; adjusting the soil pH can release some nutrients fixed by the soil, such as phosphorus, potassium, calcium, magnesium, etc., increasing the effectiveness of these nutrients, thereby improving soil fertility; appropriate soil pH can stimulate the activity of soil microorganisms, promote the decomposition of organic matter and the release of nutrients by microorganisms. The activity of microorganisms not only helps to improve soil fertility, but also improves soil structure and enhances soil's resistance to erosion.

[0032] The effect of adding decomposed and crushed agricultural and forestry waste to the river bank slope protection is:

[0033] The filling soil during transplanting contains decomposed and crushed agricultural and forestry waste, which can not only improve the soil structure of the river bank zone which is mainly composed of coarse sand and gravel, but also provide the nutrients needed for plant growth in the later stage, while also avoiding the influx of elements such as N, P, and K from the river caused by artificial fertilization.

[0034] The role of planting green manure plants:

[0035] During the vegetation growth period, green manure crops can absorb a large amount of nutrients and directly cover the soil surface for return to the field after the growth is completed. After the organic matter of green manure crops is decomposed, it can provide nutrients to the soil, improve the soil environment and increase soil fertility. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] From the above, we can see that the effect of turning over the river bank slope protection soil is:

[0046] Tilling the soil can make it loose and increase the porosity in the soil, which is conducive to receiving and storing rainwater and improving the water storage capacity of the soil;

[0047] Soil that has not been tilled for a long time is prone to form a plow bottom layer, which makes the soil compact and is not conducive to the growth of plant roots. Tilling the soil can effectively break the plow bottom layer, deepen the tillage layer, and provide a wider growth space for plant roots.

[0048] Tillage can improve soil aeration, making it difficult for toxic gases in the soil to accumulate. It also provides more air to the roots and promotes the activity of aerobic microorganisms. These microorganisms release more nutrients, such as nitrogen, phosphorus, and potassium, in the process of decomposing organic matter, thereby improving soil fertility.

[0049] Turning the soil can also promote the mineralization of organic matter in the soil, converting organic matter into fast-acting nutrients that are easily absorbed and utilized by plants, such as fast-acting nitrogen and fast-acting phosphorus.

[0051] The present invention further specifically details that the substances for adjusting the pH are quicklime, slaked lime, sulfur powder and aluminum sulfate;

[0052] From the above, we can see that the effect of adjusting the pH value of river bank slope protection soil is:

[0053] Adjusting soil pH can improve soil physical properties, such as soil structure, air permeability and water retention. Appropriate soil pH is conducive to the formation of soil aggregate structure, enhancing soil air permeability and water permeability, thereby improving soil water and fertilizer retention capacity;

[0054] Adjusting the soil pH can release some nutrients such as phosphorus, potassium, calcium, magnesium, etc. that are fixed in the soil, increase the effectiveness of these nutrients, and thus improve the fertility of the soil;

[0055] Appropriate soil pH can stimulate the activity of soil microorganisms, promote the decomposition of organic matter and the release of nutrients by microorganisms. The activity of microorganisms not only helps to improve soil fertility, but also improves soil structure and enhances soil resistance to erosion.

[0056] Step 4: Mix the fermented and decomposed agricultural and forestry waste in proportion and add it to the river bank slope protection;

[0057] The present invention further specifically describes that the crushed agricultural and forestry waste includes sawdust and crushed wheat straw;

[0058] From the above, we can see that the filling soil during transplanting contains decomposed and crushed agricultural and forestry waste, which can not only improve the soil structure of the river bank zone which is mainly composed of coarse sand and gravel, but also provide the nutrients needed for plant growth in the later stage, while also avoiding the influx of elements such as N, P, and K into the river due to artificial fertilization.

[0059] Step 5: Plant green manure plants. When the green manure crops grow to a certain stage, cut off their stems and leaves and turn them into the soil so that their organic matter can decompose in the soil and release nutrients.

[0060] The present invention further specifically describes that the green manure plants are astragalus, alfalfa and sweet clover;

[0061] From the above, we can see that during the growth period of vegetation, green manure crops can absorb a large amount of nutrients and directly cover the soil surface for return to the field after the growth is completed. After the organic matter of green manure crops is decomposed, it can provide nutrients to the soil, improve the soil environment and increase soil fertility.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
