Description

Technical Field

[0001] The present invention relates to the technical field of soil ecological restoration, and in particular to a soil ecological restoration method suitable for transplanting plants and a plant transplanting method. Background Art

[0002] Plant transplantation is a common and important technology in modern agriculture, landscaping and ecological restoration projects. However, due to urban expansion, industrial activities, the use of agricultural chemicals and other reasons, many soils have been polluted and degraded to varying degrees, which brings challenges to plant transplantation. In order to ensure the survival rate and long-term healthy growth of transplanted plants, as well as to protect and restore the soil ecosystem, soil ecological restoration and scientific plant transplantation methods are particularly important.

[0003] For example, the Chinese patent with announcement number CN111149596B discloses a soil ecological restoration method suitable for transplanting Pistacia chinensis and a Pistacia chinensis transplanting method. The following steps are included: a mature straw compost layer, a livestock manure layer, a lime layer, and a leguminous green manure plant planting layer are distributed in the transplant soil from bottom to top, and leguminous green manure plants are planted in the leguminous green manure plant planting layer, and different layers are separated by thin soil; after the leguminous green manure plants mature, the leguminous green manure plants are pulled out and buried on the spot to form a leguminous green manure humus layer, and a composite bacterial agent soil layer is laid on the leguminous green manure humus layer, and the leguminous green manure humus layer and the composite bacterial agent soil layer are separated by thin soil; phloem bark is covered on the composite bacterial agent soil layer, and earthworms are introduced into the planting area to complete the soil restoration and obtain the transplant area after the restoration. The present invention uses a large amount of green and environmentally friendly substances to carry out ecological restoration of the soil, so that the soil is more suitable for the growth of Pistacia chinensis, and it is still very green and environmentally friendly as a whole.

[0004] The existing technology has the following problems:

[0005] Existing soil ecological restoration methods and plant transplantation methods for transplanting plants, when implementing soil improvement, are not efficient in reducing soil salinity and alkali content, shortening soil improvement time, and are not conducive to soil moisture content and permeability, reducing plant growth. At the same time, transplanting is not accompanied by favorable pruning and reasonable pit digging, which will reduce survival rate and drainage problems. Summary of the invention

[0006] The present invention provides a soil ecological restoration method suitable for transplanting plants and a plant transplanting method to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0014] Test the pH and salinity of the soil where the crops are to be planted, remove the soil with high salinity, and fill it with soil with low salinity;

[0015] Alternatively, an isolation system can be established, using lime, slag and other materials to isolate the saline-alkali soil from the foreign soil, and using films to isolate it from the surrounding saline-alkali soil horizontally.

[0016] Preferably, in step S1, the microbial community and organic matter content in the soil are checked to determine the biological health status of the soil.

[0017] Preferably, in step S2, soil pH is adjusted by using lime, sulfur, or iron sulfate, or chemical fixatives are used to reduce the mobility of heavy metals.

[0020] Plant leguminous green manure plants in the leguminous green manure plant planting layer, and separate different layers by thin soil;

[0021] When the leguminous green manure plants mature, they are pulled out and buried on the spot to form the leguminous green manure compost layer;

[0022] A composite bacterial agent soil layer is laid on the leguminous green manure compost layer, with a thin layer of soil between the two layers, and then earthworms are introduced to complete soil remediation, and then phloem bark is covered on the composite bacterial agent soil layer;

[0023] The thin soil is interspersed with peat, perlite, etc. to improve the air permeability and drainage of the soil and thus improve the soil structure.

[0024] Preferably, after step S3, step S4 is used to apply organic covering to protect the soil surface to reduce erosion and water evaporation.

[0025] A method suitable for plant transplantation comprises the following steps:

[0026] Step B1 Select suitable plants: Select high-quality, adaptable local plants or verified exotic plant seedlings according to soil conditions, climate and ecological goals;

[0027] Step B2 Preparation before transplanting: Before transplanting, trim damaged or overgrown roots and ensure that the root ball is intact. Transplant during the plant's dormant period or when the climate is suitable to reduce stress;

[0028] Step B3 Transplantation process: dig a pit in the soil ecological cultivation repaired in claims 1-6, and the size of the pit should be 1.5 to 2 times the root ball to ensure good drainage at the bottom of the pit;

[0029] Place the plant in the hole, making sure the root neck is level with the ground.

[0030] Preferably, after step B3, management after transplantation in step B4 is as follows: backfilling with the improved soil, lightly compacting to remove air, but avoiding over-compacting, and immediately watering after transplantation to help the roots to be in close contact with the soil;

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figure 1 As shown, a soil ecological restoration method suitable for transplanting plants includes the following specific implementation steps:

[0040] S1. Soil assessment;

[0041] S2. Pollutant treatment;

[0042] S3, soil improvement;

[0043] S4. Soil cover and protection;

[0044] In step S1, the structure, texture, pH value, nutrient content, and pollutant level of the soil are comprehensively analyzed; a physical test method: a cutting method is used to further understand the physical properties of the soil, such as compactness and porosity;

[0045] Sieving method: Use sieves with different apertures to sieve soil samples, measure the proportion of particles with different particle sizes, and classify them according to the texture triangle diagram. Common soil textures include sandy loam, loam and silt;

[0046] Acid-base titration method: Mix the soil sample with hydrochloric acid and sulfuric acid, react under certain conditions, and then use a pH electrode to measure the pH value of the solution;

[0047] Chemical analysis methods: including acid hydrolysis, alkaline hydrolysis, hot extraction, etc., used to determine the total elements (such as total nitrogen, phosphorus, potassium) and effective nutrients (such as available phosphorus, available potassium, etc.) in the soil. These methods usually require the use of precision instruments such as atomic absorption spectrometry, ICP-OES or I CP-MS for determination;

[0048] Heavy metal analysis: Atomic absorption spectrometry or inductively coupled plasma optical emission spectrometry (ICP-OES) is used to determine the content of heavy metals in the soil, such as lead, cadmium, chromium, etc.

[0049] Test the pH and salinity of the soil where the crops are to be planted, remove the soil with high salinity, and fill it with soil with low salinity;

[0050] The pH value of saline-alkali land is usually considered to be excessive when it is above 9.5, the pH value of light saline-alkali land is 7.1 to 8.5, and the pH value of heavy saline-alkali land exceeds 9.51;

[0051] The classification and pH range of saline-alkali land are as follows:

[0052] Light saline-alkali land: the salt content is less than 0.3%, and the pH value is 7.1 to 8.5;

[0053] Heavy saline-alkali land: the salt content exceeds 0.6 parts per thousand and the pH value exceeds 9.5;

[0054] Moderate saline-alkali land: The salt content is between light saline-alkali land and heavy saline-alkali land, with a pH value of 8.5 to 9.5;

[0055] The ratio of digging out soil with high salt-alkali content and backfilling with soil with low salt-alkali content is set at 1:1.

[0056] Alternatively, an isolation system can be established to isolate the saline-alkali soil from the foreign soil using materials such as lime and slag, and to isolate it from the surrounding saline-alkali soil laterally using films, which is less costly.

[0057] Case 1: Urban green space soil remediation

[0058] S1. Soil assessment:

[0059] Sampling: Sampling was carried out at three depths: 0-15cm, 15-30cm, and 30-45cm. Three samples were collected from each layer and mixed;

[0060] Laboratory analysis:

[0061] Physical properties: The soil texture is sandy with low porosity and high density;

[0062] Chemical properties: pH value is 6.5, organic matter content is 1.5%, lead and cadmium content exceeds the standard;

[0063] Biological properties: fewer microbial species and numbers, low soil enzyme activity;

[0064] S2. Pollutant treatment:

[0065] Heavy Metal Treatment:

[0066] Treat heavy metals with lime and phosphate to form insoluble compounds;

[0067] Introducing hyperaccumulators (such as Indian mustard) for phytoremediation;

[0068] S3. Soil improvement:

[0069] Organic matter addition:

[0070] Add mature compost, 10kg per square meter;

[0071] Nutrient supplement:

[0072] Supplement nitrogen, phosphorus and potassium fertilizers, adding 50g urea, 100g superphosphate and 50g potassium sulfate per square meter;

[0073] Soil structure improvement:

[0074] Use bentonite to improve soil structure, adding 1kg per square meter;

[0075] S4. Soil cover and protection:

[0076] Cover Material:

[0077] Use straw and sawdust for mulch, with a thickness of 10-15cm;

[0078] Protection measures:

[0079] Avoid excessive disturbance and reduce human activities; introduce earthworms to enhance the stability of soil ecosystem;

[0080] Effect evaluation:

[0081] Physical properties: soil porosity increases and density decreases;

[0082] Chemical properties: The organic matter content increased to 3%, and the heavy metal content was significantly reduced;

[0083] Biological properties: The types and number of microorganisms increase, and the activity of soil enzymes improves.

[0084] like Figure 1 As shown, in step S1, the microbial community and organic matter content in the soil are checked to determine the biological health status of the soil.

[0085] like Figure 1 As shown, in step S2, soil pH is adjusted by using lime, sulfur, etc., or chemical fixatives are used to reduce the mobility of heavy metals.

[0086] like Figure 1 As shown, after step S2, compost and well-rotted farmyard manure are used from step S3 to improve soil fertility and structure, and at the same time, the lack of minerals and trace elements are supplemented according to the soil test results.

[0087] like Figure 1 As shown, in step S3, a decomposed straw compost layer, compost, a decomposed farmyard manure layer, a lime layer, and a leguminous green manure plant planting layer are distributed in sequence from bottom to top on the soil;

[0088] Plant leguminous green manure plants in the leguminous green manure plant planting layer, and separate different layers by thin soil;

[0089] When the leguminous green manure plants mature, they are pulled out and buried on the spot to form the leguminous green manure compost layer;

[0090] A composite bacterial agent soil layer is laid on the leguminous green manure compost layer, with a thin layer of soil between the two layers, and then earthworms are introduced to complete soil remediation, and then phloem bark is covered on the composite bacterial agent soil layer;

[0091] Peat, perlite, etc. are interspersed between thin soils to improve soil aeration and drainage, thereby improving soil structure.

[0092] The decomposed straw compost layer (bottom layer) strengthens the soil structure: during the decomposition process, the straw will form stable organic matter, which helps to increase the looseness and porosity of the soil, reduce soil compaction, and improve the air permeability and water permeability of the soil; improves water retention capacity: the organic colloids after the straw decomposition can absorb and retain a large amount of water, improve the water retention capacity of the soil, and help crops grow under drought conditions; promotes root development: the soft soil environment is conducive to the growth and expansion of the crop root system, so that the root system can absorb nutrients and water in the soil more deeply;

[0093] The compost layer (middle layer) provides comprehensive nutrients: compost is rich in macroelements such as nitrogen, phosphorus, potassium, and trace elements such as iron, copper, and zinc. These nutrients are necessary for crop growth and can provide comprehensive nutritional support for crops; improve soil physical and chemical properties: organic matter in compost can improve soil pH, increase soil organic matter content, increase soil biological activity, and promote the reproduction and activity of soil microorganisms, thereby enhancing soil fertility and nutrient supply capacity; improve soil fertility: continuous application of compost can gradually increase the organic matter content in the soil, making the soil more fertile, which is conducive to the growth and development of crops;

[0094] The decomposed farmyard manure layer (upper layer) quickly releases nutrients: Compared with other organic fertilizers, the nutrients in decomposed farmyard manure are more easily absorbed and utilized by crops, and can quickly provide the required nutrient support for crops; regulate soil temperature: in cold seasons, the decomposed farmyard manure layer can maintain soil temperature and reduce the impact of frost damage on crops; in hot seasons, it can lower the soil surface temperature and prevent crops from heat damage; inhibit weed growth: the farmyard manure layer covering the soil surface can weaken the light intensity and affect the photosynthesis of weeds, thereby reducing the growth amount and growth intensity of weeds in the field.

[0095] like Figure 1 As shown, after step S3, step S4 is used to apply organic covering (such as straw, wood chips) to protect the soil surface and reduce erosion and water evaporation.

[0096] like Figure 2 As shown, a method suitable for plant transplantation comprises the following steps:

[0097] Step B1 Select suitable plants: Select high-quality, adaptable local plants or verified exotic plant seedlings according to soil conditions, climate and ecological goals;

[0098] Step B2 Preparation before transplanting: Before transplanting, trim damaged or overgrown roots and ensure that the root ball is intact. Transplant during the plant's dormant period or when the climate is suitable to reduce stress;

[0099] Step B3 Transplantation process: dig a hole in the above repaired soil ecological cultivation, and the size of the hole should be 1.5 to 2 times the root ball, ensuring good drainage at the bottom of the hole;

[0100] Place the plant in the hole, making sure the root neck is level with the ground.

[0101] like Figure 2 As shown, after step B3, perform post-transplant management in step B4: backfill with improved soil, compact lightly to remove air, but avoid over-compacting, and water thoroughly immediately after transplantation to help the roots to get in close contact with the soil; water regularly after transplantation, fertilize appropriately, and prevent pests and diseases.

[0102] Case 2: Soil remediation in mining area reclamation

[0103] Background: Due to long-term mining activities, the soil in abandoned mining areas has become seriously acidic, extremely lacking in nutrients, and has serious damage to the soil structure.

[0104] Implementation steps and methods:

[0105] S1. Soil assessment:

[0106] Sampling: Sampling was carried out at three depths: 0-15cm, 15-30cm, and 30-45cm. Three samples were collected from each layer and mixed;

[0107] Laboratory analysis:

[0108] Physical properties: The soil texture is clay, with very low porosity and high density;

[0109] Chemical properties: pH value is 4.0, organic matter content is 0.5%, and nutrients are extremely lacking;

[0110] Biological properties: The types and numbers of microorganisms are extremely small, and the activity of soil enzymes is extremely low;

[0111] S2. Pollutant treatment:

[0112] Acidification treatment:

[0113] Use lime to neutralize soil acidity, adding 2kg of lime per square meter;

[0114] S3. Soil improvement:

[0115] Organic matter addition:

[0116] Add mature compost, 15kg per square meter;

[0117] Nutrient supplement:

[0118] Supplement nitrogen, phosphorus and potassium fertilizers, adding 100g urea, 200g superphosphate and 100g potassium sulfate per square meter;

[0119] Soil structure improvement:

[0120] Use bentonite to improve soil structure, adding 2kg per square meter;

[0121] S4. Soil cover and protection:

[0122] Cover Material:

[0123] Use mulch to reduce water evaporation and soil erosion;

[0124] Protection measures:

[0125] Avoid excessive disturbance and reduce mechanical activity;

[0126] Introducing earthworms and beneficial microorganisms to enhance the stability of the soil ecosystem;

[0127] Effect evaluation:

[0128] Physical properties: soil porosity increased significantly and density decreased;

[0129] Chemical properties: pH value increased to 6.0, organic matter content increased to 2.5%, and nutrient content increased significantly;

[0130] Biological properties: The types and number of microorganisms increased significantly, and the activity of soil enzymes increased significantly;

[0131] Comparative Analysis

[0132] Urban green space soil remediation:

[0133] Success points: Effectively reduced heavy metal content, improved soil structure, and increased organic matter and nutrient content;

[0134] Challenges: Continuous monitoring and management are required to prevent secondary contamination;

[0135] Soil remediation in mining areas:

[0136] Success points: significantly neutralized soil acidity, improved soil structure, and increased nutrient content;

[0137] Challenge: Long-term conservation and management are needed to prevent soil acidification and nutrient loss.

[0138] Through these two comparative cases, it can be seen in the conclusion that soil ecological restoration methods suitable for transplanting plants need to be designed and adjusted in response to different soil problems and environmental conditions; urban green space soil restoration mainly focuses on heavy metal pollution and the supplement of organic matter and nutrients. The pruning and digging of plants before and after transplantation in the above methods can improve the survival rate and drainage of plants; the layer-by-layer improvement of the soil can increase the soil water content and permeability, improve the soil physical properties, and is conducive to plant growth. Each step should be adjusted according to specific soil problems and environmental conditions to ensure the maximization of the restoration effect.

[0139] The working principle of the present invention is as follows: a comprehensive analysis is conducted on the soil structure, texture, pH value, nutrient content, pollutant level, etc.; the pH value and salinity content of the polluted soil to be planted are tested, the soil with high salinity content is dug out, and the soil with low salinity content is backfilled; or an isolation system is established to isolate the saline-alkali soil from the foreign soil with materials such as lime and slag, and to isolate it from the surrounding saline-alkali soil laterally with a film, etc., which is relatively low in cost; the microbial community and organic matter content in the soil are checked to judge the biological health of the soil, and the soil is protected by using lime, sulfur, etc. Huang etc. to adjust soil pH, or use chemical fixatives to reduce the mobility of heavy metals, use compost and well-rotted farmyard manure to improve soil fertility and structure, and at the same time, supplement the lack of minerals and trace elements according to the soil test results, distribute well-rotted straw compost layer, compost, well-rotted farmyard manure layer, lime layer, and leguminous green manure plant planting layer in the soil from bottom to top; plant leguminous green manure plants in the leguminous green manure plant planting layer, and separate different layers with thin soil; when the leguminous green manure plants mature, pull them out and bury them on the spot to form the leguminous green manure compost layer ; Lay a composite bacterial agent soil layer on the leguminous green manure compost layer, with a thin soil interval between the two layers, and then introduce earthworms to complete soil remediation, and then cover the composite bacterial agent soil layer with phloem bark; the thin soil intervals are filled with peat, perlite, etc. to improve the soil's aeration and drainage, and improve the soil structure; then use organic mulch (such as straw, sawdust) to protect the soil surface, reduce erosion and water evaporation; then, according to soil conditions, climate and ecological goals, select high-quality and adaptable local plants or verified large seedlings of foreign plants, and plant them in Prune damaged or overly long roots and ensure the root ball is intact; transplant during the plant's dormant period or when the climate is suitable to reduce stress; dig a pit in the restored soil ecological cultivation, and the size of the pit should be 1.5 to 2 times the size of the root ball, ensuring good drainage at the bottom of the pit; place the plant in the pit, ensuring that the root neck is flush with the ground, backfill with improved soil, and compact lightly to remove air, but avoid excessive compaction; water fully immediately after transplantation to help the roots to be in close contact with the soil; water regularly after transplantation, fertilize reasonably, and prevent pests and diseases.
