A small cultivation trough with embedded water surrounded by water

Abstract

The invention discloses a water-surrounding embedded small cultivation trough, which belongs to the technical field of horticultural cultivation. It includes a water storage tank, a matrix tank and an agricultural film, the agricultural film includes a first layer of agricultural film and a second layer of agricultural film, the water storage tank is surrounded by at least 4 cement hollow bricks to form a rectangular structure, and the cavity of the cement hollow brick Vertical to the ground of the planting field; the bottom end of the water storage tank is located 15-20cm below the ground of the planting field and is horizontal, and the top of the water storage tank is flush with the ground of the planting field or 2-3cm higher than the ground; the The substrate tank is located inside the water storage tank, and the bottom of the substrate tank is flush with the bottom end of the water storage tank. The small cultivation tank of the invention can save cultivation substrate, reduce substrate replacement cost and workload, and has low construction cost, easy construction and dismantling, no damage to ecological environment, and is suitable for shallow root vegetable crops.

Description

technical field [0001] The invention relates to a small embedded cultivation tank surrounded by water, belonging to the technical field of horticultural cultivation. Background technique [0002] At present, the cultivation trough used in production is made of solid bricks and cement. It needs to harden the ground. Its specifications are usually 90-100cm wide and 30-40cm deep. The construction cost is high, and once it is built, it is difficult to tear down. When some of the salt content in the filling of the matrix tank is too high, due to the impermeability of the bottom of the cultivation tank, the salt cannot penetrate into the lower soil layer to be eliminated, and the pesticide residues in the matrix also cannot be eliminated. The substrate ecology of the cultivation trough is complex, the planted crops have increased pests and diseases, and pesticide residues cannot be ruled out. At the same time, the width of the cultivation trough is large. For some crops with sha...

AI Technical Summary

Problems solved by technology

[0002] The cultivation tank currently used in production is made of solid bricks and cement. It needs to harden the ground. Its specifications are usually 90-100cm wide and 30-40cm deep. The construction cost is relatively high, and once it is built, it is difficult. tear down

When some of the salt in the filler of the matrix tank is too high, due to the limitation of the impermeability of the bottom of the cultivation tank, the salt cannot penetrate into the lower soil layer and be removed, and the pesticide residues in the matrix cannot be eliminated. This is currently The ecological complexity of the cultivation tank matrix, the increase of plant diseases and insect pests, and the important reasons why pesticide residues cannot be ruled out

At the same time, the width of the cultivation tank is relatively large. For some crops with shallow root system and low planting density, in terms of fertilizer and water management, the supply is often greater than the demand, resulting in waste.

In addition, the current cultivation tank has a large tank body, which requires a large amount of filling substrate, which is costly and labor-intensive to replace the substrate. The inconvenience of replacing the substrate often makes it impossible to replace the substrate in time, resulting in an excessively high load on the cultivation substrate. , seriously affecting the quality of agricultural products
