A composite molding sand planting structure

Abstract

A composite sand planting structure containing a porous planting sand and a nutrient planting sand that are capable of being directly used for water retention and fertilizer retention during planting. The composite sand planting structure comprises a planting container, and a porous planting sand and a nutrient planting sand that are laid in the planting container. The porous planting sand is a sand ball with a porous structure that is formed by adhering natural sand particles by using an adhesive at least comprising a hydrophilic adhesive, pores suitable for adsorption being formed between adjacent natural sand particles. The nutrient planting sand comprises the porous planting sand and a nutrition film covering the surface of the porous planting sand. With the water retention and fertilizer retention properties of the porous planting sand and the nutrient planting sand and the air permeability of the planting container, the sand planting structure can reduce fertilizer loss and facilitate plant growth.

Description

technical field [0001] The invention belongs to the field of sand planting, and in particular relates to a composite sand planting structure utilizing water-retaining and fertilizer-retaining porous planting sand, nutrient planting sand and a self-defense and air-permeable planting container that can be directly used for planting. Background technique [0002] Desertification is a natural phenomenon, which is caused by climate change caused by the movement of the earth's dry belt, which leads to desertification in local areas. Moreover, with the increasingly harsh global climate and the rapid population growth, the land has been over-exploited, cultivated and raised, resulting in faster and faster global desertification, less arable land, and continued decline in agricultural and animal husbandry production capacity. Especially for a country like my country with a small land and a large population, the negative impact of the growing desertification process leading to the red...

Problems solved by technology

[0006] However, the treatment of sand in this invention adopts a general simple mixing process, directly mixing organic waste or by-product powder and soil microorganisms and inoculating them on the sand, and using the coagulation of microorganisms in the presence of microorganisms can realize sand separation. The adhesion force between them can reduce the loss of sand and soil caused by wind and sand flow. The sand aggregates described in this invention are more used in desert planting to prevent loss. For daily planting, water and fertilizer conservation are required. performance, the adhesion between microorganisms is not applicable, and the sand has not undergone any pretreatment, whether its smooth outer surface is suitable for microbial inoculation adsorption and how much adsorption capacity is also open to question, so the sand cohesion The body is not suitable for the planting with sand as the main planting body in daily planting. Therefore, there are still great limitations for the large-scale promotion of sand planting technology
