Problems solved by technology

However, due to the lack of soil, lack of water, little fertilizer, and a certain height, the exposed rock mass faces great difficulties in recovery.
[0003] Vegetation can be restored to a certain extent by using alien soil spraying technology, but the existing soil spraying substrates have poor water retention, poor water holding capacity, and insufficient strength, and are prone to collapse under their own gravity or rainfall infiltration And other issues

Abstract

The invention discloses a guest soil spraying base material and a preparation method thereof. Each square meter of the spraying base material includes the following components: 0.5-0.8 kg of wood fiber, 0.015-0.018 kg of water-retaining agent, and 0.01-0.013 kg of clay agent , 9.8kg of fine-grained soil, 0.035-0.04kg of compound fertilizer and 1-2kg of short rice straw and chaff. The present invention can improve the water retention and water holding capacity of the sprayed substrate, and the consolidated strength.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation. More specifically, the present invention relates to soil-sprayed substrates. Background technique [0002] In some areas, due to the destruction of vegetation, soil erosion has resulted in the formation of a large number of exposed rock masses, which require ecological restoration. However, due to the lack of soil, lack of water, little fertilizer, and a certain height, the exposed rock mass faces great difficulties in restoration. [0003] Vegetation can be restored to a certain extent by using alien soil spraying technology, but the existing soil spraying substrates have poor water retention, poor water holding capacity, and insufficient strength, and are prone to collapse under their own gravity or rainfall infiltration And other issues. Contents of the invention [0004] The purpose of this invention is to provide guest soil spraying substrate and preparation method t...
