Agricultural cultivation substrate and its production method and application

Abstract

The invention discloses an agricultural culturing medium, a producing method thereof and an application thereof, and belongs to the field of production of agricultural culturing media. The agricultural culturing medium is prepared from charcoal powder, fresh grass leaf powder, dry grass leaf powder, fungicides and pyroligneous liquid. The invention further discloses the producing method of the agricultural culturing medium. The method includes the following steps that 1, the mixture of the fungicides, the pyroligneous liquid and the charcoal powder is prepared, then the mixture, the fresh grass leaf powder and the dry grass leaf powder are evenly mixed, and a compost heap body is prepared; 2, heap-sealing anaerobic fermentation is carried out, and then aerobic fermentation is carried out; 3, the heap body is sealed, then overturned and aired, and the agricultural culturing medium is obtained. According to the agricultural culturing medium, the producing method and the application, landscaping waste serves as raw materials to produce the agricultural culturing medium, the landscaping waste is recycled, and the produced agricultural culturing medium can improve a soil carbon pool and improve soil, can be applied to gardening, agricultural production or forestry production.

Description

technical field [0001] The invention relates to an agricultural cultivation substrate, and also relates to a method for producing an agricultural cultivation substrate with landscaping waste, belonging to the field of agricultural cultivation substrate production. Background technique [0002] Landscaping waste mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including tree branches, fallen leaves, grass clippings, spent flowers, Shrub pruning and other trimmings. With the continuous strengthening of ecological construction and urban and rural greening, the wastes such as fallen leaves and branches produced by landscaping have increased sharply. In the autumn and winter seasons when there are many fallen leaves, because they cannot be digested in time, the phenomenon of random piles and random burning occurs from time to time, which not only destroys the ecological environment of the city, but also wastes resour...

AI Technical Summary

Problems solved by technology

In the autumn and winter when there are many fallen leaves, because they cannot be digested in time, the phenomenon of random piles and burning occurs from time to time, which not only destroys the ecological environment of the city, but also wastes resources.

[0003] China has made some progress in the research on the resource utilization of landscaping waste, but these studies have the following deficiencies: First, the sources of landscaping waste include tree branches, fallen leaves, grass clippings, flower rot, and shrubs. Prunings and other trimmings have different raw material components and cannot be processed under the same process conditions; second, it is difficult to eliminate ammonia (NH 3 ) and other odor components to the atmospheric environment; third, the production cycle is relatively long and the production efficiency is not high; fourth, mature technical equipment and production lines have not been formed; the most critical point is that the focus of landscaping waste composting research is concentrated In terms of changes in nutrients such as nitrogen, phosphorus, and potassium, there are few research reports on the degradation of lignin and cellulose substances and the formation of humus in the composting process.

However, the large-scale development and use of peat has resulted in the destruction of the ecological environment and caused serious environmental and resource pressures. Therefore, in countries with less peat resources, even in countries with rich peat resources, the exploitation and utilization of peat has begun to be restricted.
