Air-permeable anti-seepage sand and sand-based planting tank using the air-permeable and anti-seepage sand

Abstract

The invention discloses air-permeable seepage-proof sand and a sand-based planting tank using the same, belonging to the field of a crop planting tank. The air-permeable seepage-proof sand provided by the invention consists of a plurality of crude sand particles, seepage-proof resin and an adhesive, wherein the volume ratio of the crude sand particles to the seepage-proof resin to the adhesive is 200:(8-20):(5-15). The sand-based planting tank provided by the invention comprises a plurality of air-permeable seepage-proof sand plates which form a groove-like container in a surrounding manner, wherein each air-permeable seepage-proof sand plate comprises air-permeable seepage-proof sand, an adhesive and a solidifying agent, and the volume ratio of the air-permeable seepage-proof sand to the adhesive to the solidifying agent is (4-6):(3-4):(1-2). The air-permeable seepage-proof sand and the sand-based planting tank provided by the invention have the advantages of air permeability, seepage prevention, water and fertilizer retention, and long service life.

Description

Technical field [0001] The invention belongs to the field of crop planting troughs, and in particular relates to a kind of breathable and seepage-proof sand and a sand-based planting trough using the breathable and seepage-proof sand. Background technique [0002] The crop planting trough is a trough-shaped container in which the cultivation substrate is placed for planting crops. Crop planting troughs are mainly used for plants with too many continuous cropping problems and elevated planting (such as cleaner production of fruits, vegetables, etc.). [0003] Conventional plastic planting troughs or foam boxes have a short service life due to their poor material strength. Moreover, these plastic or foam boxes have no ventilation function, which is not conducive to the growth of plant roots. The ordinary sand-based planting trough, although it has the function of air permeability, is easy to leak, that is, its effect of retaining water and fertilizer is poor. [0004] In view of thi...

Problems solved by technology

[0003] Conventional plastic planting tanks or foam boxes have a short service life due to the poor strength of their materials

Moreover, these plastic or foam boxes have no ventilation function, which is not conducive to the growth of plant roots

However, the common sand-based planting tank, although it has the function of ventilation, is easy to leak, that is, its water and fertilizer retention effect is relatively poor.
