A green field soil physical property improver and its application method

Abstract

The invention relates to a land soil improver, especially a green land soil physical property improver and its use method, which mainly includes the following components: organic waste compost, wood biochar, rice husk ash, coconut peat, attapulgite powder With microbial bacterial agent, the volume percentage is: organic waste composting: woody biochar: rice husk charcoal: coconut bran: attapulgite powder=40~55%: 2~4%: 2~4%: 2~4%: 0.5 ~1%; the present invention utilizes organic waste resource products, organic and inorganic materials, microbial agents and other materials to scientifically formulate a green space soil physical property improver according to a certain proportion, aiming at lawns, tree and shrub planting holes, road green belts, etc. Different types of green space habitats, combined with microbial agents, can effectively improve the degradation of soil physical properties such as green space soil bulk density, air permeability, infiltration rate, aggregate structure, and non-capillary porosity, and have a good long-term effect on the growth of green space plants The role of promotion is to improve the sustainability of green space ecological functions.

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
