Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, specifically a method for enhancing plant diversity in engineering disturbance areas through segmented application of various compound fertilizers. Background Technology

[0002] Various engineering construction activities, such as road construction, mining, and building construction, inevitably disturb the ecological environment of the surrounding area. The soil structure of the disturbed area is damaged, and a large amount of native vegetation is destroyed, leading to significant changes in the composition and structure of plant communities. Many plant species that originally grew in the area disappear, and plant diversity declines sharply.

[0003] This loss of plant diversity has led to a series of serious ecological problems. First, the stability of the ecosystem is affected. Plants, as producers in the ecosystem, are the foundation of the entire ecosystem. A reduction in plant species weakens the ecosystem's self-regulating capacity, making it more susceptible to external disturbances such as pests and diseases, and soil erosion. Second, habitats are destroyed. Many animals, insects, and microorganisms that depend on these plants lose their food sources and habitats, further contributing to the decline in biodiversity. Furthermore, the landscape quality of the disturbed areas also declines, affecting the ecological aesthetic value of the surrounding areas and the human living environment.

[0004] To restore the ecological environment of the project-disrupted area and improve plant diversity, some measures have been taken. Common methods include directly sowing seeds of a single or a few highly adaptable plants and applying conventional fertilization. However, these methods have many limitations.

[0005] Based on this, we propose a method for enhancing plant diversity in engineering disturbance areas through segmented application of various compound fertilizers, hoping to address the shortcomings of existing technologies. Summary of the Invention

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a method for enhancing plant diversity in engineering disturbance zones through segmented application of various compound fertilizers.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A segmented fertilization method for promoting plant diversity in engineering disturbance zones includes the following steps: (1) Conduct an in-depth investigation into the current distribution pattern of plant communities in the project disturbance area, and at the same time, trace back the composition of plant communities in the area before the project disturbance; (2) Conduct a comprehensive analysis of the climate characteristics of the engineering disturbance area, and select other plant species that can survive well in this environment. (3) Carefully select existing plant seeds before the engineering disturbance and plant seeds that are compatible with the climate environment of the engineering disturbance area, mix them in a specific ratio to obtain a diverse combination of plant seeds; (4) Sow a variety of plant seeds evenly in the disturbed area of ​​the project, and then carry out segmented fertilization operations; The segmented fertilization method uses compound multi-element fertilizer.

[0008] As a further technical solution, the investigation and analysis in step (1) specifically involves: thoroughly sorting out the existing plant species in the engineering disturbance area, comparing them with the plant species list before the engineering disturbance, and accurately identifying the plant species that disappeared due to the engineering disturbance.

[0009] As a further technical solution, step (2) requires a detailed analysis of climatic elements such as the duration of sunlight, temperature range, and precipitation patterns in the engineering disturbance area in order to identify plant seeds with obvious growth advantages and outstanding adaptability under this climatic environment.

[0010] As a further technical solution: in step (3), the mixing mass ratio of plant seeds existing before the engineering disturbance to plant seeds suitable for the climate environment of the engineering disturbance area is 8:1-1.5.

[0011] As a further technical solution: the segmented fertilization in step (4) is carried out by foliar fertilizer; the specific fertilization arrangement is as follows: fertilization is carried out during the plant growth season from May to November, fertilizing 3 times a month, with an interval of no less than 8 days between adjacent fertilizations.

[0012] As a further technical solution, the compound multi-element fertilizer is made from the following components by weight: 10-13 parts calcium ammonium nitrate, 4-6 parts potassium chloride, 0.8-1.2 parts magnesium sulfate, 2-5 parts potassium dihydrogen phosphate, 0.008-0.02 parts sodium naphthaleneacetate, 2-4 parts plant-derived compound vitality liquid, 0.1-0.4 parts sodium alginate, 0.5-1 parts nano-bentonite, 0.08-0.2 parts ammonium molybdate, 0.08-0.15 parts manganese sulfate, 0.2-0.4 parts emulsifier, and 55-65 parts water.

[0013] As a further technical solution, the preparation method of the plant-derived compound vitality liquid is as follows: Fresh, disease-free black nightshade, dandelion, and peanut shells are selected and mixed in a mass ratio of 6:1:2; the black nightshade and dandelion are washed and air-dried, and the peanut shells are dried at 40-50℃ until the moisture content is below 10%, then coarsely crushed and screened to 2-5 mm; all materials are mixed with a 70-80% ethanol solution at a mass ratio of 1:10, stirred at 200-300 r / min for 10-15 min, and extracted at 50-60℃ for 2-3 h, stirring once every 30 min during the extraction, followed by filtration. The first extract was obtained, and the residue was repeated to obtain the second extract, which was then combined. The mixed extracts were sonicated at 35 kHz and 300-400 W for 12 min, kept at 20-30℃, stirred at 4500 r / min for 35 min, and allowed to stand for 1.5 h. After filtration, the filtrate was concentrated to 1 / 3-1 / 4 volume at 40-50℃ and 0.08-0.1 MPa. The mulberry sap was then microporously filtered and mixed with the concentrated extract at a ratio of 18:2-4, stirred at 150-200 r / min for 20-30 min, bottled, and refrigerated at 4-10℃ for later use.

[0014] As a further technical solution: the mass ratio of the black nightshade, dandelion, and peanut shells is 6:1:2; the mixing ratio of the mixture to the ethanol solution is 1:10.

[0015] As a further technical solution: the frequency of the ultrasonic wave is 35kHz.

[0016] As a further technical solution: the mixing mass ratio of the extract to the mulberry juice is 18:2-4.

[0017] (III) Beneficial Effects Compared with existing technologies, this invention provides a method for enhancing plant diversity in engineering disturbance zones through segmented application of diverse compound fertilizers, which has the following beneficial effects: The method of this invention has shown significant and multi-dimensional positive effects in the field of ecological restoration of engineering disturbance areas, providing a practical and effective way to improve the ecological environment and promote ecological cycle.

[0018] During engineering construction, the ecosystem of the project disturbance area often suffers severe damage, and the original ecological balance is disrupted. The fertilization method of this invention can comprehensively and effectively restore the ecosystem of the project disturbance area. It restores the ecosystem by enriching the plant diversity of the project disturbance area. Different types of plants in an ecosystem are interdependent and interact with each other, forming a complex and stable ecological network. This rich plant diversity promotes material cycling and energy flow, improving the ecological cycle efficiency of the project disturbance area. This invention employs a rigorous scientific method to select suitable plant seeds for the project disturbance area. First, it deeply analyzes the plant species that have disappeared due to project disturbance, understanding their ecological functions and needs in the original ecosystem. Simultaneously, it screens out plant species with strong adaptability to the project disturbance environment; these plants have strong resistance and adaptability, enabling them to survive and grow under harsh environmental conditions. The seeds of these two types of plants are mixed in a specific ratio and sown into the project disturbance area, laying a good foundation for plant growth.

[0019] Building upon this foundation, the unique fertilization method of this invention further provides ample nutrients and a favorable growing environment for seed germination and plant growth. Segmented fertilization precisely delivers the necessary nutrients according to the different growth stages of the plants, avoiding waste and deficiency. The rich nutrients in the compound multi-element fertilizer, such as calcium ammonium nitrate, potassium chloride, and magnesium sulfate, provide comprehensive nutritional support for plant growth. Simultaneously, the various bioactive substances in the plant-derived compound vitality liquid stimulate seed germination and plant growth, increasing the germination rate and promoting rapid growth of germinated plants. After a period of growth, the number of plant species in the disturbed area significantly increased, greatly enriching plant diversity.

[0020] The fertilization method of this invention also has a unique ecological effect: it enables heterogeneous nutrient distribution within the ecosystem of the engineering disturbance zone. In natural ecosystems, heterogeneous nutrient distribution provides diverse ecological niche spaces for different species. Different plants have different nutrient requirements and utilization methods. The nutrient heterogeneous environment created by fertilization can meet the growth needs of different plants, allowing various plants to grow and reproduce in suitable environments. For example, some plants prefer to grow in nutrient-rich areas, while others can survive in relatively nutrient-poor environments. This diversified ecological niche space provides opportunities for survival and competition among different species, which is beneficial for maintaining and enriching plant diversity. At the same time, the increase in plant diversity further promotes the stability and complexity of the ecosystem, forming a virtuous cycle that allows the ecosystem of the engineering disturbance zone to gradually recover to a healthy and stable state.

[0021] In summary, the segmented fertilization method of the present invention has significant advantages and important application value in promoting plant diversity in engineering disturbance areas, restoring the ecological environment and improving ecological cycles, and provides an innovative and effective solution to the ecological problems caused by engineering construction.
