Abstract
The invention belongs to the technical field of agricultural soil fertilizing, and particularly relates to a soil structure improving agent for heavy soil. The soil structure improving agent is prepared by mixing the following raw materials: biomass charcoal particles with particle size of 1 to 3mm, humic acid and/or humate powder, and water, wherein the weight of the humic acid and/or humate powder is equivalent to 4 to 6% of the weight of biomass charcoal particle, and the weight of the water is equivalent to 5 to 35% of the weight of biomass charcoal particle. The soil structure improving agent provided by the invention has the advantages that the heavy soil is improved, the number of soil large aggregates is increased, the soil permeability is improved, the soil viscosity is reduced, the tillage drag is reduced, the proper tillage period is prolonged, the soil water retaining rate is improved, the soil fertility is improved, the crop output is increased, and the number of carbon sequestration by soil is increased; the method is simple, the implementing is easy, the cost is low, the effect is obvious and lasting, and the soil structure improving agent is suitable for large-area popularizing and applying.
Description
technical field [0001] The invention belongs to the technical field of agricultural soil fertilization, and in particular relates to a soil structure improver for clay-heavy soil, and also relates to a method for improving the structure of clay-heavy soil by using the soil structure improver. Background technique [0002] Soil aggregation is an important soil physical property, which affects soil air permeability, water storage capacity, tillability and plant root extension ability, and is an important factor in soil fertility. Clay-heavy soil has strong cohesiveness due to high clay content, and it is easy to form a compact core and block structure inside, and it is difficult to form soil aggregates with loose and porous interior and multi-level agglomeration mechanism, especially large agglomerates larger than 1mm body, which is a major hindrance in many low-yielding fields with heavy texture. Therefore, promoting the formation of large aggregates in clay-heavy soils is a...
