Description

Technical Field

[0001] The invention belongs to the technical field of slope greening, and specifically refers to a planting matrix suitable for vine plants on high and steep slopes and a preparation method thereof. Background Art

[0002] The ecological stability of high and steep slopes is crucial to preventing soil erosion and maintaining ecological balance. In such an environment, vines are an ideal choice for improving slope stability due to their climbing and covering characteristics. The planting matrix is ​​one of the key factors to ensure the successful growth of vines on high and steep slopes. The planting matrix for high and steep slopes is usually a mixture of lightweight materials such as vermiculite, perlite or foam particles. These materials can provide the necessary gaps to promote air circulation and water penetration. Under drought conditions, vines need sufficient water to maintain growth. Therefore, some organic matter such as leaf mold, peat or coconut bran is added to the matrix. These substances can absorb and slowly release water while providing nutrients required for plant growth.

[0003] In order to enhance the stability of the substrate, some structural materials are usually added to it. These materials can combine with the soil and plant roots to increase the overall stability of the slope, help plants better fix on the slope, and reduce erosion caused by weathering or water erosion. On high and steep slopes, vines are usually planted by spraying or hydraulic seeding, spraying the seeds and substrate mixture directly onto the slope to ensure that the seeds can germinate under the best growth conditions. As the plants grow, their roots will penetrate deep into the soil, helping to fix the soil and reduce erosion.

[0004] At present, the existing preparation technology of the planting matrix of vines on high and steep slopes has the following problems: first, the stability of the existing planting matrix of vines on high and steep slopes is low, the adhesion and erosion resistance of the matrix are weak, and it is easy to cause soil erosion; second, the drainage and air permeability of the existing planting matrix of vines on high and steep slopes are poor, and it is impossible to drain excess water, resulting in root diseases of vines or erosion of slopes; third, the water retention and nutrient supply and nutrient retention capabilities are weak, resulting in drought and withering of vines and stunted growth. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a planting matrix suitable for vines on steep slopes and a preparation method thereof. In order to solve the problems of low stability, poor drainage and air permeability, and weak water retention and nutrient retention capacity of the existing planting matrix for vines on steep slopes, the present invention uses a viscous matrix composition and a basic solution to mix to form a soil matrix, and evenly disperses the fermentation-type slow-release nutrient in the soil matrix.

The fast-absorbing nutrients are mixed with coated slow-release particles. The fermented slow-release nutrient can provide vines with sufficient nutrients in a long-term and efficient manner; the bathing horn bone sponge with strong water absorption capacity and pores is frozen and ground to increase the number of pores contained, improve water absorption and water retention, and is mixed with degradable methyl acrylate The rough gravel is crushed into small particles, and then mixed with arachidonic acid and heated. The carboxyl group in arachidonic acid reacts chemically with the hydroxyl group formed by activation on the surface of the gravel, and the surface of the gravel is modified to be hydrophobic, so that the gravel particles can not only increase the friction of the planting matrix, prevent landslides caused by gravity on steep slopes, but also promote the discharge of excess water. Methacrylate anhydride gelatin has a three-dimensional network structure. When mixed with modified gravel particles, peat soil, and leaf mold, it can provide more attachment points and enhance the stability and adhesion of the sticky matrix composition. The base containing potassium carbonate, magnesium sulfate, sugar alcohol boron, and zinc citrate is added. The solution is mixed with a viscous matrix composition and a fermented slow-release nutrient agent to supplement the trace elements required for the growth of vines on steep slopes and provide a suitable pH for the growth of vines. The composite bacterial agent in the fermented slow-release nutrient agent can promote the formation of soil aggregates, and cooperate with the viscous matrix composition to further improve the stability and drainage of the planting matrix. The prepared planting matrix suitable for vines on steep slopes is stable, not easy to lose, can drain excess water, contains a porous structure that is conducive to the penetration and expansion of plant roots, provides sufficient space for the roots, has strong water retention and nutrient supply and nutrient retention capabilities, and can provide vine nutritional components for a long time.

[0161] Experimental Example 3: Test for determining long-term nutrition supply.

[0162] The test steps for determining the long-term nutrient supply of the planting substrate for vines on steep slopes prepared in Examples 1-5 of the present invention are as follows:

[0163] (1) Eight plots of test sites on steep slopes were opened up and divided into five experimental groups, two comparative groups and one control group. The experimental group prepared a planting matrix suitable for steep slope vines, the comparative group prepared a planting matrix suitable for steep slope vines and the control group prepared a common planting matrix for vines (purchased from Chengdu Qianqi Flowers and Trees Co., Ltd.) to transplant Chinese ivy seedlings with a plant height of 10 cm. Each steep slope test plot used 100 kg of each planting matrix. Each planting matrix was mixed with ultrapure water at a weight ratio of 1:0.2. After mixing evenly, it was used. Each test plot was equidistantly transplanted with 10×10 cm. The plant height of Chinese ivy seedlings was recorded every 20 days for 160 days. The leaf morphology and stem state of each group of Chinese ivy were observed on the 160th day and recorded in Table 1. No external fertilizer was applied during this period.

On the 160th day, the leaves of the Chinese ivy were bright green and shiny, some leaves were yellow, and the stems were thicker. The ordinary liana planting matrix in the control group was used for transplanting the Chinese ivy seedlings with a height of 10 cm. Every 20 days, the height of the Chinese ivy seedlings was recorded. The height of the Chinese ivy plant after 160 days of continuous recording was 31.4 cm, 46.3 cm, 72.5 cm, 86.9 cm, 98.5 cm, 114.7 cm, 123.6 cm, and 134.5 cm. On the 160th day, the leaves of the Chinese ivy were bright green and shiny, some leaves were yellow, and the stems were thicker. d was used to record the plant height of the Chinese ivy seedlings.
