A compound nutrient sand planting structure

Abstract

Provided is a sand planting structure containing compound-type nutritional planting sands capable of being directly used for planting and able to retain water and fertilizer. The sand planting structure comprises a planting container and compound-type nutritional planting sands placed in the container; the planting sands comprise porous sand balls, and microbial membranes and nutrient film coating the surface of the porous sand balls successively from the inside to the outside; the porous sand balls are of porous structure and formed by bonding natural sand particles with binders containing at least hydrophilic binders, and there are pores suitable for adsorption between the adjacent natural sand particles. The sand planting structure helps to reduce the loss of fertilizer and is conducive to plant growth by means of the ability to retain water and fertilizer of the compound-type nutritional planting sands and the planting container with permeability to air.

Description

technical field [0001] The invention belongs to the field of sand planting, and in particular relates to a sand planting structure utilizing water-retaining and fertilizer-retaining composite 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 reduction of agricultural...

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
