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

Embodiment 1

[0057] The planting sand described in this embodiment is aimed at planting leafy plants.

[0058] The porous planting sand described in this embodiment is a sand ball with a porous structure formed by bonding natural sand particles with a particle size of 70-100 mesh, hydrogenated bisphenol A epoxy resin and hydrophilic epoxy resin. The diameter of the planting sand is 1-2 cm, and pores of 150-300 μm are formed between adjacent natural sand grains.

[0059] The water-retaining and fertilizer-retaining planting sand described in this embodiment is prepared by the following method: sieve the natural sand, select 100Kg of sand with a particle size of 70-100 mesh, 21Kg of hydrogenated bisphenol A epoxy resin and affinity 9Kg of water-based epoxy resin binder, mixed evenly to achieve bonding to form sand balls with a diameter of 1-2cm, and pores of 150-300 μm are formed between adjacent natural sand grains for future use.

Embodiment 2

[0063] Such as figure 1 As shown, the sand planting structure described in this embodiment includes a planting container and porous planting sand laid in the planting container. The porous planting sand is the same as that described in Example 1, and the planting container is the same in structure and material as the potting container described in Example 3 in Chinese Patent CN202043482U.

[0064] The nutrient solution involved in this embodiment is the same as the nutrient solution described in Example 1, and the planting plant and the cabbage seedlings of the planting plant described in Example 1 are seedlings transplanted at the same time, and the cabbage seedlings are planted in this embodiment. In the planting container of the described sand planting structure, and observe by pouring the prepared nutrient solution.

Embodiment 3

[0066] The nutritional components, porous planting sand and Chinese cabbage seedlings used in this embodiment are the same as in Example 1, except that the seedlings are planted in an impermeable container without water seepage holes at the bottom, and their growth conditions are observed.

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.
