Earth surface organic plant residue composting process and application of earth surface organic plant residue composting

Abstract

The invention discloses an earth surface organic plant residue composting process and application of earth surface organic plant residue composting, and belongs to the technical field of earth surfaceorganic plant residue composting. The earth surface organic plant residue composting process comprises the following steps: crushing earth surface organic plant residues generated by roadbed surfacecleaning, and performing airing until the earth surface organic plant residues are half-dry; mixing the crushed earth surface organic plant residues with an organic fertilizer and pig manure in proportion, and performing composting by adopting a forced ventilation static stack composting system to obtain an earth surface organic plant residue composting product. According to the composting process, the composting time is relatively short, the product stability is high, and the composting quality reaches the national standard; and the slope soil taking the surface soil and the organic residuecompost product as the main foreign soil base material is rich in organic matters, and the total nitrogen, the quick-acting potassium and the quick-acting phosphorus are obviously greater than those of the control slope and the surface soil, so that the nutrients are more sufficient, and the growth requirements of slope plants can be met.

Description

technical field [0001] The invention belongs to the technical field of surface organic plant residue composting, and in particular relates to a surface organic plant residue composting process and an application of surface organic plant residue composting. Background technique [0002] Road is the main mode of transportation in our country. In recent years, my country's road construction has developed rapidly. The construction and expansion of highways inevitably change the functions of the original land, especially the topsoil cleaning process in highway construction often completely cleans out the surface cultivated soil and surface vegetation within the road area. The cleaned topsoil (including surface plant residues) is often regarded as waste piled up in road construction, forming a new spoil ground, occupying land, affecting the landscape, and easily causing new water and soil erosion. And other ecological and environmental factors also have adverse effects. [0003...

Problems solved by technology

The strip-stack composting system is a low-level composting system, which has the following disadvantages: it occupies a large area, has a long maturity cycle, and requires a lot of turning machinery and manpower; compared with other composting systems, the strip-stack composting requires more Monitoring to ensure adequate ventilation and temperature; Odors are generated when the pile is turned, which adversely affects the living environment of the public; Strip composting systems are susceptible to weather conditions, e.g. A large loss of heat reduces the temperature of the heap and slows down the fermentation rate of the heap, and the moisture content of the heap changes in the rainy season and is easy to damage the structure of the heap; because the strip-stack system needs to maintain good ventilation, it is often used in the system Need to add a considerable proportion of fillers

However, the one-time investment is large, the operation is complicated, the maintenance cost is high, and the adaptability to the change of sludge properties is not strong.
