Embodiment 1

[0036] This embodiment provides a kind of preparation method of organic greening base material, concrete steps are as follows:

[0037] 30kg of wet garbage is pulverized, passed through a 40-mesh sieve, and then mixed evenly with 30kg of yellow clay with a water content of 20%. The mixed materials are piled into mountain peaks for open-air composting. According to the measurement results of C and N content in the raw material, the water content of the mixed material is adjusted to about 50%, and the carbon-nitrogen ratio is 30:1-35:1. During the whole fermentation process, turning and throwing treatment is carried out every day, so that the materials can be fully contacted with oxygen as much as possible, so that the produced organic fertilizer can achieve the best fertilizer effect. When turning over for the first time, put 1.7kg of urease inhibitor and nitrification inhibitor into the material and mix well. After the material is fermented for 20 days, use a sieving machine...

Embodiment 2

[0039] This embodiment provides a kind of preparation method of organic greening base material, concrete steps are as follows:

[0040] 40kg of wet garbage is pulverized, passed through a 50-mesh sieve, and mixed evenly with 40kg of yellow clay with a water content of 30%. The mixed materials are piled into mountain peaks for open-air composting. According to the measurement results of C and N content in the raw material, the water content of the mixed material is adjusted to about 60%, and the carbon-nitrogen ratio is 20:1-25:1. During the whole fermentation process, turning and throwing treatment is carried out every day, so that the materials can be fully contacted with oxygen as much as possible, so that the produced organic fertilizer can achieve the best fertilizer effect. When turning over for the first time, put 2.5kg of urease inhibitor and nitrification inhibitor into the material and mix well. After the material is fermented for 30 days, use a sieving machine to s...

Embodiment 3

[0042] This embodiment provides a kind of preparation method of organic greening base material, concrete steps are as follows:

[0043] 50kg of wet garbage is pulverized, passed through a 60-mesh sieve, and mixed evenly with 30kg of yellow clay with a water content of 40%. The mixed materials are piled into mountain peaks for open-air composting. According to the measurement results of C and N content in the raw material, the water content of the mixed material is adjusted to about 70%, and the carbon-nitrogen ratio is 25:1-30:1. During the whole fermentation process, turning and throwing treatment is carried out every day, so that the materials can be fully contacted with oxygen as much as possible, so that the produced organic fertilizer can achieve the best fertilizer effect. When turning over for the first time, put 3.5kg of urease inhibitor and nitrification inhibitor into the material and mix well. After the material is fermented for 40 days, use a sieving machine to s...

Abstract

The invention discloses an organic greening base material and a preparation method thereof. The base material comprises the following components in parts by weight of dry basis: 50-60 parts of yellowclay; 20-30 parts of wet garbage; 1-3 parts of a urease inhibitor; 1-3 parts of a nitrification inhibitor; 1-3 parts of mycorrhiza; 2-6 parts of a water-retaining agent; 3-4 parts of an adhesive; 1-3parts of cement; 6-7 parts of plant seeds and 10-15 parts of water. Organic matters are converted into humus, so that the fertilizer retention, water retention and thermal insulation properties of thesoil are improved, the quantity of microorganisms in the soil is increased, and the decomposition and conversion capacity of the microorganism compost organic fertilizer is promoted; according to themethod, the urease inhibitor and the nitrification inhibitor are used for carrying out nitrogen preservation treatment on composting of the organic materials, nitrogen loss is reduced, meanwhile, theurease inhibitor can inhibit soil urease activity, the process that nitrogen is hydrolyzed into ammonium nitrogen is effectively delayed, volatilization loss of ammonia is reduced, and the nitrification inhibitor can inhibit denitrification and volatilization of NH3.

Description

technical field [0001] The invention relates to the field of greening substrates in slope greening protection engineering, in particular to an organic greening substrate and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of construction and transportation industries, more and more slope projects have emerged, and slope safety protection has become more and more important. Flexible support, such as prestressed bolt support, has a better effect, but there is still the danger of gravel falling on the slope surface; hanging net sprayed concrete can play a better protective effect on the slope surface, but the landscape is very poor. In contrast, ecological slope protection, that is, strengthening the slope through plant roots, can not only achieve a good supporting effect, but also take into account the landscape, ecology and economy, so it has been widely valued. The traditional ecological slope protection methods i...
