Modifier for physical properties of greenbelt soil and use method thereof

Abstract

The invention relates to a land soil modifer, in particular to a modifer for the physical properties of greenbelt soil and a use method thereof. The modifer mainly comprises the following components:organic waste compost, wood charcoal, rice hull ash, coco coir, attapulgite powder and a microbial agent, wherein a volume percent ratio of the organic waste compost to the wood charcoal to the rice hull ash to the coco coir to the attapulgite powder is (40-55%): (2-4%): (2-4%): (2-4%): (0.5-1%). The modifer for the physical properties of greenbelt soil is scientifically prepared from recycling products of organic waste, organic and inorganic materials, the microbial agent and other materials according to a certain proportion, and is applied to different types of greenbelt habitats such as lawns, arbor and shrub planting holes and road greenbelts; and through usage of the modifer and microbial agents, the problem of degradation of soil physical properties such as volume weight, air permeability, infiltration rate, aggregate structure, non-capillary porosity and the like of the greenbelt soil is effectively improved, a good long-acting promotion effect is achieved on the growth of greenbelt plants, and the sustainability of the ecological function of greenbelt is improved.

Description

technical field [0001] The invention relates to a land soil improver, in particular to a greenfield soil physical property improver and its application method. Background technique [0002] Green space soil provides a growth and development environment for the underground parts of garden plants, supplies water, air and nutrients needed by plants, is one of the important components of urban ecosystems, and is also a storage and purifier of urban pollutants, while maintaining a good soil ecology One of the prerequisites for the system is good soil physical structure. Soil physical structure is the foundation of soil fertility, which affects the quantity and coordination of various elements of soil fertility, and also affects soil physical, chemical and biological characteristics. Changes in the physical properties of green space soil are largely affected by human activities. Green space soil has chaotic structure, large spatial differences, many foreign pollutants such as con...

Problems solved by technology

[0004] The soil source of the green space is complex and the soil layers are disordered, which not only greatly affects the effect of landscaping, but also is not conducive to the sustainable development of urban gardens. Gardeners have carried out many theoretical studies and practical applications on the improvement of soil fertility in green spaces. However, insufficient attention is paid to the physical properties of the soil. The physical properties of the soil have no lower impact on the growth of garden plants than other soil chemical properties, and sometimes even the most critical factors that determine plant growth, such as soil bulk density, infiltration capacity, aggregates, and non-capillary porosity. Relevant research is limited to the screening of physical property improvement materials and the verification of improvement effects, and there are few studies on the effect of soil physical property improvers on plant growth, exploration of soil physical property improvers application methods under different green space habitat conditions, and soil improvement. Study on Evaluation of Application Effect of Physical Property Improver
