Soil conditioner and nursery stock planting method adopting soil conditioner

Abstract

The invention relates to the field of landscaping construction, and particularly discloses a soil conditioner and a nursery stock planting method adopting the soil conditioner. The soil conditioner comprises the following raw materials in parts by weight: 5-8 parts of straw; 10-15 parts of volcanic ash; 40-50 parts of bentonite; 8-12 parts of earthworm soil; 3-5 parts of organic matter; 4-9 parts of silicon pumice; 1.5-3.5 parts of calcium mannitol; and 2-7 parts of linseed oil residue. The soil conditioner can promote formation of soil aggregate structures, increase soil porosity, enhance air permeability and water permeability of soil, improve fertilizer and water retention capacity and buffer performance of the soil, remarkably improve the particle size content of soil particles, and is high in oxygenation efficiency and large in oxygenation amount; and the growth and culture of organisms in the soil are facilitated, and the survival rate of the seedlings is greatly improved.

Description

technical field [0001] The application relates to the field of landscaping construction, more specifically, it relates to a soil improver and a seedling planting method using the soil improver. Background technique [0002] Soil improver, also known as soil conditioner, refers to a material that can improve soil physical properties and promote crop nutrient absorption, but does not provide plant nutrients itself. Soil amendments work by binding many small soil particles to form large, water-stable aggregates. It is widely used to prevent soil erosion, reduce soil moisture evaporation or excessive transpiration, save irrigation water, and promote healthy plant growth. [0003] In the Chinese invention patent application document with the publication number CN112080281A, a soil improver for landscaping and its preparation method are disclosed, including: mixing tree powder and phosphoric acid solution, adding disproportionated rosin and stirring evenly, extruding and activati...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when it is applied in the process of urbanization, the soil matrix is ​​mostly artificial backfill soil, containing a large amount of soil intrusions, such as gravel, lime, asphalt and construction waste, etc., making the soil compacted and compaction, resulting in a decrease in oxygen concentration and air permeability in the soil, which is not conducive to plant growth
