Abstract

The invention discloses an urban soil regulator and belongs to the technical field of fertilizer. The regulator provided by the invention is prepared by mixing ferrous sulphate, carbamide, calcium superphosphate, calcium peroxide, natrium biboricum and zinc sulfate based on a certain mass percentage. The regulator provided by the invention mainly comprises oxygen-releasing agents, calcium fertilizers, long-acting nitrogen, long-acting phosphorus, quick-acting potassium and microelement fertilizers. By regulating the structure and physical and chemical state of the compacted urban soil, the regulator can break the urban soil compaction, loose soil and improve soil ventilation, thereby ensuring the constrained nutrition and water to move more effectively in the soil; the total population and species of soil microorganisms in the soil are increased, the fertilizer-and-water permeability of the soil is enhanced, and the occurrence of plant diseases and insect pests is reduced; and calcium and oxygen can be provided continuously and steadily, the anaerobic condition of the plant roots is improved, and seed germination and new root growth are promoted. The regulator provided by the invention is convenient to use, cost-effective, environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a fertilizer capable of improving urban soil structure and permeability. Background technique [0002] In the process of urban landscape construction and channel greening, most of the ground is hardened and soil respiration is cut off. At the same time, due to trampling, hardened pavement and machinery, the soil near the city and the channel is very easy to be compressed, resulting in soil degradation and soil pollution. The layers of the body are disordered, the topsoil is often removed or buried by the subsoil, and the soil layer is often mixed with the bottom layer of stiff soil or raw soil, as well as a large amount of gravel and construction waste; soil nutrients are deficient, and its organic matter content, nitrogen, and phosphorus content are generally low. Low; in particular, the roots of street trees are squeezed into the limited soil under the hardened road surface...
