Composite nutrient sand planting structure

Abstract

The invention belongs to the field of sand planting, and particularly relates to a sand planting structure containing composite nutrient planting sand which can be directly used for planting and has functions of water retention and fertilizer retention. The sand planting structure comprises a planting container and the composite nutrient planting sand laid in the planting container. The planting sand comprises a porous sand ball, a microbe bacterium membrane and a nutrient membrane, wherein the microbe bacterium membrane and the nutrient membrane are sequentially wrapped outside the surface of the porous sand ball from inside to outside. The porous sand ball is in a porous structure formed by natural sand granules and adhesion agents at least containing hydrophilic adhesives in an adhesive mode, and a pore suitable for adsorption is formed between each two adjacent natural sand granules. According to the composite nutrient sand planting structure, water retention performance and fertilizer retention performance of the composite nutrient planting sand are made use of, the venting planting container performs an assistant function, fertilizer loss is beneficially reduced, and growth of plants is benefited.

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
