Abstract

The invention discloses an artificial organic aggregate structure suitable for soil improvement, which comprises a sandless concrete outer layer and an organic matter inner layer, the volume ratio of the inner and outer layers is 2:8, the inner layer is decomposed compost, and the outer layer includes gravel, Cement, water, powder binder, composite fiber, mass ratio 15:3:1:0.23:4. The organic aggregates are columnar, with a diameter and height of 30mm. The organic aggregate of the present invention has a stable multi-level porous structure, and has excellent water retention, fertilizer retention and air permeability. The stored organic matter provides long-term nutrition, and can be applied to various types of heavy soil as a product to improve soil It can be widely used in urban street tree rhizosphere soil improvement and park green space soil improvement, and can also be used as a substitute for volcanic rock as a component of cultivation media.

Description

technical field [0001] The invention relates to the field of resources and environment, in particular to an artificial organic aggregate structure suitable for soil improvement and a preparation method thereof. Background technique [0002] Due to high utilization intensity and serious human interference, soil quality problems are one of the main problems common to urban green spaces, such as compaction degradation, nutrient deficiency, and pollution. It is especially manifested in the serious degradation of soil physical properties, including large bulk density, poor ventilation, easy water accumulation, and poor permeability. During road construction, there are poor growth and death of street trees, and the over-compacting of the soil is the main reason. Therefore, soil improvement has become a major task of urban green space construction. At present, the improvement techniques adopted in agricultural and forestry production are diversified, among which adding organic ma...
