Problems solved by technology

[0004] In the cost composition of the slope spraying greening project, the matrix material accounts for about 30%, and the cost is relatively high. The main reason is that the peat soil with the largest amount enters from the northeast, is itself damp (moisture content 40-50%), and the freight is expensive. The price of each ton of peat soil reaching Shenzhen is as high as 500 yuan

Embodiment

[0037] Example: Implementing sludge-based spray-mixed vegetation greening on the rock slope of Jiujingkou, Yantian District, Shenzhen City The Jiujingkou slope in Yantian District belongs to the exposed rock mass slope surface formed by road excavation, and the application area is about 8000m2 2 , Most of them are irregular, and the overall slope is steep, with a slope of 60-70 degrees.

[0038]Composition of sludge spraying greening matrix, in terms of every 1m 3 The soil is calculated by adding the following components:

[0039] Decomposed sludge 30Kg

[0040] Organic matter Mushroom fertilizer 10kg, bran shell 3kg, sawdust 3kg, chicken manure 1kg

[0041] Compound fertilizer 1kg

[0042] PR-3005M water retaining agent 0.05kg

[0043] Rubber powder 1kg

[0044] Gypsum 1kg

[0045] Plant seeds Bermudagrass 120g, Molasses 60g, American thorn 40g, Acacia lobata 30g, Bean edamame 40g, Wing bean 20g

[0046] water 60L

[0047] The soil is a mixture of local terracotta and...

Abstract

The sludge spraying and seeding afforesting matrix is one kind of composition prepared through mixing fermented sludge, organic matter, composite fertilizer, water retaining agent, glue powder, pH regulator, plant seed and water at normal temperature. It is sprayed to exposed slope and mountain for restoring vegetation in short period. The present invention can result in excellent economic benefit and environment benefit.

Description

technical field [0001] The invention belongs to the technical field of environmental protection slope greening and mountain gap ecological management, and is particularly suitable for a sludge sprayed greening substrate that can not only allow plants to grow and develop but is not easily washed away by rainwater. technical background [0002] In recent years, due to the acceleration of development and construction and urbanization, the contradiction between urban construction and ecological protection has become increasingly aggravated. During the construction of infrastructure such as roads, railways, water conservancy and municipal facilities, a large number of excavated mountains and flats and quarried soil have not only destroyed the topography and native vegetation, but also formed many broken mountain zones with exposed slopes as the main feature. This has an extremely adverse impact on soil and water conservation, ecological protection, urban landscape and human settl...
