Problems solved by technology

Moreover, the pH value of red loam soil is low, mostly acidic or strongly acidic soil, and the soil quality is poor.
In the prior art, there is a lack of greening substrates suitable for the special environment in Yunnan, and it is impossible to effectively adjust the physical and chemical properties of the soil. However, if the amount of bonding material added is too large, it is easy to cause soil compaction, which is not conducive to plant growth.
At the same time, the organic matter content in existing substrates is generally low, which is difficult to meet the basic needs of plant growth in plateau mountainous areas

Abstract

The invention discloses a biological basic material to protect the afforestation on the rock slope. It is composed of lignite, biological bacterial, adjusting solvent of the basic material, fibre, water-loss reducer and binding agent. The characteristic is: the component proportion in weight with 65 to 80 percent lignite, 0.2 to 0.35 percent biological bacterial manure, 2 to 5 percent adjusting solvent of the basic material, 20 to 35 percent fiber, 0.02 to 0.05 percent water-loss reducer, and 0.02 to 0.05 percent binding agent. The invention, with a biological basic material to protect the afforestation on the rock slope, is mainly made of specialty organic resource lignite in Hunan province. It is rich in organic substance and the element of nutrition, which will meet the demand of the plant growth. The raw material is easy to get and the process is simple, besides, it is clean and can be applied in slope under the 90th degree, especially in plant protection in acid or strong acid soil.

Description

technical field [0001] The invention relates to a vegetation planting substrate, in particular to a greening substrate for biological protection of rock slopes. Background technique [0002] At present, the bio-protection greening substrate of rocky slopes mostly adopts the soil spraying technology, that is, a layer of soil suitable for plant growth is sprayed on the exposed rocky slopes with high-pressure equipment. Since rock slopes are mostly semi-weathered or unweathered rock masses, and the thickness of the sprayed soil layer is limited, it is required that the sprayed guest soil must have the necessary organic matter and nutrients for the long-term growth of plants. Ordinary soil lacks the necessary organic matter and nutrients for plant growth. At the same time, the acidity and alkalinity (PH value) of the soil also has a great impact on whether the plants can survive. Therefore, whether the guest soil sprayed can meet the long-term growth needs of the plants. The ke...
