Problems solved by technology

A plant growth substrate with excellent properties is the basis and key to the ecological restoration of rocky slopes. Although the plant growth substrates in the prior art can make the slope form vegetation in a short period of time to achieve the effect of regreening, the foreign soil layer on the slope is prone to appear Hardening and cracking, not resistant to rain erosion, slow plant growth, not suitable for the growth of trees and shrubs, grass planting is easy to degrade, serious soil waste, airtight soil, poor water and fertilizer retention capacity

Embodiment 1

[0014] A rocky slope plant growth substrate, specific implementation steps: 15 parts of organic rice husks (rice husks) and 10 parts of slow-release fertilizer and 100 parts of soil (this soil is selected from nature with the required physical and chemical properties suitable for plant growth) Soil, the sand content of the soil is not more than 5%, and then dried, crushed, and sieved, the particle size is 0.5~10mm.) Mix evenly, and then add 0.1 part of expanded potato starch, 0.1 part of hydroxypropyl methylcellulose Dissolve in 25ml of water, slowly pour into the above soil, stirring constantly. Afterwards, dissolve 0.1 part of calcium chloride and 0.25 part of sodium silicate in 25ml of water, mix well, pour the above solution into a beaker with loam, stir continuously with a glass rod, and stir evenly. According to the slope plant species, the plant growth substrate is sprayed on the rocky slope.

Embodiment 2

[0016] A rocky slope plant growth substrate, specific implementation steps: mix 15 parts of organic rice husk (7.5 parts of rice husk, 7.5 parts of sawdust) and 10 parts of slow-release fertilizer with 100 parts of soil (this soil is selected from all kinds of soil suitable for plant growth) Soil in nature that requires physical and chemical properties, the sand content of the soil is not more than 5%, and then the particle size is 0.5~10mm after drying, crushing, and sieving.) Mix evenly, and then mix 0.25 parts of expanded potato starch, 0.25 parts Hydroxypropyl methylcellulose was dissolved in 30ml of water, slowly poured into the above soil, and kept stirring. Afterwards, dissolve 0.1 part of calcium chloride and 0.25 part of sodium silicate in 30ml of water, mix well, pour the above solution into a beaker filled with loam, stir continuously with a glass rod, and stir evenly. According to the slope plant species, the plant growth substrate is sprayed on the rocky slope.

Embodiment 3

[0018] A rocky slope plant growth substrate, specific implementation steps: 15 parts of organic rice husk (sawdust) and 10 parts of slow-release fertilizer and 100 parts of soil (this soil is selected from the natural world with the required physical and chemical properties suitable for plant growth) Soil, the sand content of the soil is not more than 5%, and then dried, crushed, and sieved, the particle size is 0.5~10mm.) Mix evenly, dissolve 0.5 parts of expanded potato starch, 0.1 parts of hydroxypropyl methylcellulose In 40ml of water, slowly pour into the above soil, stirring constantly. Then dissolve 0.1 part of calcium chloride and 0.25 part of sodium silicate in 40ml of water, mix well, pour the above solution into a beaker filled with loam, stir continuously with a glass rod, and stir evenly. According to the slope plant species, the plant growth substrate is sprayed on the rocky slope.

Abstract

The invention provides a rock slope plant growth substrate and a preparation method thereof. The rock slope plant growth substrate is prepared from the following components in parts by weight: 100 parts of soil, 50-80 parts of water, 0.1-0.5 part of expanded potato starch, 10 parts of fertilizer, 15 parts of organic matter, 0.1 part of hydroxypropyl methyl cellulose, 0.1 part of calcium chloride and 0.25 part of sodium silicate. All the raw materials disclosed by the invention are non-toxic, environment-friendly and degradable, wherein the puffed potato starch is a natural adhesive, so that the soil has certain cohesiveness, and the puffed potato starch can also enhance the soil strength, resist rain wash and prevent leakage. The used raw material puffed potato starch has high water absorption capacity and water-retaining property and good flocculation effect, and can improve the structure of soil and increase the air permeability and the water-retaining property of the soil. Accordingto the method, crop straw is fully utilized as organic matter of the rock slope plant growth substrate, waste is utilized, a certain amount of nitrogen, phosphorus, potassium and other nutrients areprovided for vegetation growth, and the cost is reduced.

Description

technical field [0001] The invention relates to a rock slope plant growth substrate and a preparation method thereof, belonging to the technical field of soil improvement. Background technique [0002] Rocky slopes are generally steep and have no vegetation conditions. At the same time, exposed rocky slopes will also bring a series of problems. It is an urgent requirement to solve the above-mentioned problems by taking effective measures to green the rocky slope as soon as possible under the premise of ensuring the stability of the slope. Rock slope greening can protect land, ecology and landscape. A plant growth substrate with excellent properties is the basis and key to the ecological restoration of rocky slopes. Although the plant growth substrates in the prior art can make the slope form vegetation in a short period of time to achieve the effect of regreening, the foreign soil layer on the slope is prone to appear Hardening and cracking, not resistant to rain erosion...
