Problems solved by technology

However, peat is a non-renewable resource. It is the foundation of forest growth and the existence of wetlands. It is a valuable forest resource. Once it is damaged, it will be difficult to recover. At present, the exploitation of peat has been banned in China.
However, the price of peat in foreign countries is high, and a large amount of spraying will inevitably increase the cost
At the same time, in the current ecological restoration, more and more attention is paid to the use of native tree species. However, native tree species generally have a low degree of industrialization and fewer seeds, while restoration by spraying often faces differences in soil properties (physical and chemical properties, microbial communities, etc.). Larger, and lead to low seed survival rate, which is not conducive to the ecological restoration of native tree species

Abstract

The invention discloses a preparation method of artificial peat and an in-situ ecological restoration spraying matrix prepared by using the same, and relates to the technical field of ecological restoration. The artificial peat provided by the invention is obtained by adding nitrogen to broken branches that have been sterilized and degraded. , to obtain the base material; mix the understory litter and the humified surface soil in the target spraying area with the base material, and adjust the water content to obtain the fermentation base material; after decomposing the fermentation base material, obtain; The spraying substrate can be obtained by mixing with the original soil, adhesive and water retention agent in the target spraying area. The artificial peat provided by the invention can replace natural peat, with low cost and good effect, especially the prepared spraying substrate for spraying High efficiency and high plant life rate.

Description

technical field [0001] The invention belongs to the field of ecological restoration, in particular to an artificial peat and an in-situ ecological restoration spraying matrix prepared by using the artificial peat. Background technique [0002] Seeding is a new technology suitable for greening of rock-soil slopes with a high degree of weathering and rock-soil slopes. It uses a jet machine to spray organic substrates such as grass seeds and water-retaining agents onto the slope, and the organic materials are tightly combined with the slope under the action of pressure to form a substrate layer for plant growth and development. Spray seeding is especially suitable for slope protection and greening of roads, railways, railways, and river slopes. If it is weathered rock, soft rock with less soil, and soil slope with high soil hardness, it can be used for slopes with large slopes and rocky patches. Drawing lessons from the work of spraying anchor rods and steel bars, the purpose ...
