Multi-hole planting sand and sand planting structure

Abstract

The invention belongs to the field of sand planting and particularly relates to multi-hole planting sand which can be directly used for retaining water and fertilizer and a sand planting structure with the planting sand. The planting sand is a sand ball with a multi-hole structure which is formed by sticking natural sand grains and binder which at least contains hydrophily binder, and a hole which is suitable for adsorbing is formed between the adjacent natural sand grains. According to the planting sand, existing natural sand grains are utilized to form holes through cementation, holes which are suitable for use and enable external beneficial compositions are enabled to be loaded on the surface of the sand ball to be formed between the adjacent sand grains, multi-hole performance of the sand ball is utilized to effectively maintain nutrition fertilizer, fertilizer such as the nutrition compositions which are fertilized in the outside world in a planting process is loaded in the holes which are formed among the sand grains, and therefore a situation that the fertilizer is lost with the loss of water is prevented, and use ratio of the fertilizer is increased.

Description

technical field [0001] The invention belongs to the field of sand planting, and in particular relates to a water-retaining and fertilizer-retaining porous planting sand which can be directly used for planting and a sand planting structure containing the planting sand. 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 and plantable soil is fatal.

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
