Description

Technical Field

[0001] The invention relates to the technical field of grassland restoration, and in particular to a method for implanting biological materials for natural grassland restoration. Background Art

[0002] Grassland restoration is a complex but vital process that aims to restore the ecological function and health of grasslands. The implantation of biomaterials in grassland restoration is an effective method that aims to improve the ecological function and health of grasslands by introducing specific biomaterials. Common biomaterials mainly include seeds, seedlings, microorganisms and other biomaterials. When restoring, it is necessary to select appropriate biomaterials according to the specific conditions of the grassland to ensure their adaptability and effectiveness.

[0003] Announcement No.: CN114027110B discloses a method for implanting biomaterials in high-altitude desertified grassland areas prone to strong winds. The invention plants shrubs and covers the surface of the irrigation holes with a mixture of mud made of cow / sheep manure, natural waste soil, grass seeds, adhesive and water, and presses it into a fixed irrigation hole cover; the strip grooves opened between the shrub rows are also filled with the mixed mud to form a composite sand barrier; a mixture of cow / sheep manure and grass seeds is sown between the irrigation hole fixed cover and the composite sand barrier, and the loose soil is compacted. This not only prevents biomaterials and organic fertilizers in high-altitude desertified grassland areas prone to strong winds from being blown away by the wind, but also resists erosion by strong winds. The operation is simple and the cost is low.

[0004] However, this method has certain disadvantages when used. This method mainly manages grasslands in high-altitude desertified and windy areas by planting shrubs and covering the surface of the holes with a mixture of cow / sheep manure, natural waste soil, grass seeds, adhesives and water. However, it takes a certain amount of time for the planted shrubs to survive and grow smoothly to withstand the frequent strong winds. If certain measures are not taken to protect the planted shrubs during this period, the desertified soil caused by the strong winds will bury the shrubs, resulting in a low survival rate of the planted shrubs and poor grassland recovery. In addition, it is necessary to spend time and energy to replant the shrubs many times in the later stage, which leads to the undesirable situation of repeatedly replanting shrubs.

[0005] Therefore, it is necessary to provide a method for implanting biomaterials for natural grassland restoration to solve the above technical problems. Summary of the invention

[0006] The present invention provides a method for implanting biological materials for natural grassland restoration, which solves the technical problem that the survival rate of planted shrubs is relatively low when the existing biological material implantation method for grassland restoration in the related art is used.

[0007] In order to solve the above technical problems, the method for implanting biomaterials for natural grassland restoration provided by the present invention comprises the following steps: Step S1: Pre-processing of grass grid materials, S11: Material Cleaning: Wear gloves, beat a handful of wheat straw or rice straw in the wind, beat off the dead leaves on the surface of the wheat straw or rice straw, leaving high-quality wheat straw or rice straw, and stack the cleaned wheat straw or rice straw into a pile; Remove the dead leaves on the surface of the reeds and cut the reeds into 50 cm long tubes. The cut tubes need to be crushed to split the tubes and change them into flexible materials. S12: Woven straw curtains: Before weaving, water is sprinkled on the surface of wheat straw, rice straw and reed to make it moist to avoid breaking during the weaving process. Then, a straw mat machine is used for weaving. The weaving ratio of wheat straw and rice straw to reed is 2:0.6-1. During the weaving process, wheat straw or rice straw and reed are mixed and discharged. The weaved straw mat is rolled and stored in a dry environment or under the sun. Step S2: making compost and auxiliary substrate, The wheat straw, rice straw, reed leaves and crop straw left over from making straw mats are crushed and mixed with river mud and animal feces to form organic materials. After mixing, add appropriate amount of clean water. The ratio of organic materials to water is 1:1. In order to accelerate the fermentation process, fermentation bacteria can be added. Mix the fermented organic fertilizer with the soil, with the ratio of organic fertilizer to soil being 1:0.3-0.4, to make an auxiliary matrix; Step S3: preparing mixed grass seeds and mixed materials, S31: When preparing mixed grass seeds, mix cool-season and warm-season grass seeds. Specifically, the cool-season grass seeds are bentgrass, ryegrass and bluegrass, and the warm-season grass seeds are buffalo grass, bermudagrass and white clover. The ratio of cool-season to warm-season grass seeds is 3:1. S32: Mix the prepared mixed grass seeds with the auxiliary matrix to form a mixed material.

The interval between each group of straw mat barriers is one meter. Step S5: Planting small shrubs and sowing grass seeds, First, the soil at intervals of 60 cm within each set of straw mat barriers is turned over, and then the mixed material is spread between the turned soil and each set of straw mats.

[0008] Preferably, when constructing the grass grid, the rolled straw mats need to be watered before use to moisten the surface to avoid the straw mats breaking when being pressed into the ground. After the construction of the straw mat barrier is completed, the soil in the grid needs to be scraped toward the roots of the straw mats according to the situation so that a shallow arc-shaped depression is formed in the grid. The grass grids are arranged at a 45-degree angle to the main wind direction.

[0009] Preferably, when turning the soil at intervals of 60 cm within each set of straw curtain barriers, it is necessary to clean out the clods and garbage in the soil. When planting small shrubs, the backfill soil at about 3 / 5 of the lower part of the soil ball should be tamped, and 2 / 5 of the loose soil should be backfilled on top. The surface of the soil ball should be covered with soil about 8 cm thick. After planting the small shrubs, the first watering should be done within 24 hours.

In the later stages of shrub growth, the straw barriers gradually rot under the erosion of rainwater. After the straw mats rot, they will be converted into organic matter, thereby improving soil fertility, increasing soil permeability and water retention, and ultimately improving the survival rate of planted shrubs and the recovery effect on grasslands. In addition, a large number of microorganisms will be produced during the decay of straw mats. These microorganisms decompose organic matter in the soil, which can release nutrients needed by plants while also contributing to the health and ecological balance of the soil. After the shrubs grow up, they can resist strong winds and reduce the erosion of grasslands by strong winds. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The invention provides a method for implanting biological materials for natural grassland restoration.

[0022] First embodiment: A method for implanting biomaterials for natural grassland restoration comprises the following steps: Step S1: Pre-processing of grass grid materials, S11: Material Cleaning: Wear gloves, beat a handful of wheat straw or rice straw in the wind, beat off the dead leaves on the surface of the wheat straw or rice straw, leaving high-quality wheat straw or rice straw, and stack the cleaned wheat straw or rice straw into a pile; Remove the dead leaves on the surface of the reeds and cut the reeds into 50 cm long tubes. The cut tubes need to be crushed to split the tubes and change them into flexible materials. S12: Woven straw curtains: Before weaving, water is sprinkled on the surface of wheat straw, rice straw and reed to make it moist to avoid breaking during the weaving process. Then, a straw mat machine is used for weaving. The weaving ratio of wheat straw and rice straw to reed is 2:0.6-1. During the weaving process, wheat straw or rice straw and reed are mixed and discharged. The weaved straw mat is rolled and stored in a dry environment or under the sun. The strength of reeds is higher than that of wheat straw or rice straw. The straw curtain formed by mixing and weaving the materials can well resist strong winds. Strong winds cannot easily damage the straw curtains, thereby increasing the service life of the straw curtains, so that the straw curtains can better protect the planted shrubs. After the shrubs grow smoothly, the decomposed wheat straw, rice straw and reeds can be used as nutrients to provide the shrubs for growth; Step S2: making compost and auxiliary substrate, The wheat straw, rice straw, reed leaves and crop straw left over from making straw mats are crushed and mixed with river mud and animal feces to form organic materials. After mixing, add appropriate amount of clean water. The ratio of organic materials to water is 1:1. In order to accelerate the fermentation process, fermentation bacteria can be added. Mix the fermented organic fertilizer with the soil, with the ratio of organic fertilizer to soil being 1:0.3-0.4, to make an auxiliary matrix; Use the dead leaves left over from making straw mats as organic materials for composting, making full use of natural organic materials. The auxiliary matrix can provide sufficient nutrients for the growth of shrubs and grass seeds. Step S3: preparing mixed grass seeds and mixed materials, S31: When preparing mixed grass seeds, mix cool-season and warm-season grass seeds. Specifically, the cool-season grass seeds are bentgrass, ryegrass and bluegrass, and the warm-season grass seeds are buffalo grass, bermudagrass and white clover. The ratio of cool-season to warm-season grass seeds is 3:1. S32: Mix the prepared mixed grass seeds with the auxiliary matrix to form a mixed material. The proportion of the mixed grass seeds and the auxiliary matrix is ​​adjusted independently according to the fertility and texture of the local soil while ensuring the coverage and growth effect; By mixing grass seeds, the grassland can be covered with vegetation in different seasons, so that the soil can fully resist the erosion of strong winds. After the grass seeds are mixed with the auxiliary matrix, the auxiliary matrix can serve as a hotbed for the growth of grass seeds. Step S4: Grass grid construction, First, the grass grid is laid out for construction. Two reference lines with an interval of 60 cm are marked on the ground. Two reference lines form a group, and the interval between each group of reference lines is one meter. Arrange the woven straw mats neatly along the reference line, with the center of the straw mats on the reference line. Then use the straw pressing device to press the straw mats 12-15 cm into the ground along the center of the straw mats, forming a group of straw mat barriers with an interval of 60 cm. The interval between each group of straw mat barriers is one meter. The straw curtain barrier protects the shrubs from strong winds in the early growth stage, prevents the shrubs from being buried by sand, and provides a good environment for the growth of the shrubs. In the later growth stage of the shrubs, the straw curtain gradually rots under the erosion of rainwater. After the straw curtain rots, it will be converted into organic matter, thereby improving the fertility of the soil, increasing the air permeability and water retention of the soil, and providing nutrients for the growth of the shrubs. In addition, a large number of microorganisms will be generated during the rotting process of the straw curtain. These microorganisms decompose organic matter in the soil, which can release the nutrients needed by plants and contribute to the health and ecological balance of the soil. Step S5: Planting small shrubs and sowing grass seeds, First, the soil in each set of straw curtains is turned over at intervals of 60 cm, and then the mixed material is spread between the turned soil and the intervals between each set of straw curtains, and small shrubs are planted in the turned soil. Specifically, the small shrubs are Sophora japonica, Camel thorn or Ilex affine, with a planting distance of 60-80 cm; After turning the soil within each set of straw barriers, the soil permeability can be increased, thereby improving the survival rate of shrubs after planting.

[0023] When constructing the straw grid, the rolled straw mats need to be sprinkled with water before use to moisten the surface to avoid the straw mats breaking when being pressed into the ground. After the construction of the straw mat barrier is completed, the soil in the grid needs to be scraped towards the roots of the straw mats according to the situation so that a shallow arc-shaped depression is formed in the grid. The grass grids are arranged at a 45-degree angle to the main wind direction.

[0024] When turning the soil at intervals of 60 cm within each set of straw mat barriers, it is necessary to clean out the clods and garbage in the soil. When planting small shrubs, the backfill soil at about 3 / 5 of the lower part of the soil ball must be tamped, and 2 / 5 of the loose soil should be backfilled on top. The surface of the soil ball should be covered with about 8 cm thick soil. After planting small shrubs, the first watering is required within 24 hours.

[0025] In this embodiment, unlike the existing method of implanting biological materials for restoring natural grassland, this method uses a combination of grass grids for sand control and implanting biological materials to repair grassland. In the early growth stage of shrubs, straw curtain barriers are used to protect shrubs from strong external winds, which can prevent sand from burying shrubs and provide a good environment for the growth of shrubs. Natural organic auxiliary matrix provides nutrients for the growth of shrubs and grass. In the later growth stage of shrubs, the straw curtain barriers gradually rot under the erosion of rainwater. After the straw curtains rot, they will be converted into organic matter, thereby improving soil fertility, increasing soil permeability and water retention, and providing nutrients for the growth of shrubs. In addition, a large number of microorganisms will be generated during the decay of straw curtains. These microorganisms decompose organic matter in the soil, which can release nutrients needed by plants while also contributing to the health and ecological balance of the soil. After the shrubs grow up, the shrubs can resist strong winds and reduce the erosion of grassland by strong winds, thereby achieving a good restoration effect on the grassland.
