Three-dimensional overlap-type deep-flow-channel drip irrigation soilless cultivation device

Abstract

The invention discloses a three-dimensional overlap-type deep-flow-channel drip irrigation soilless cultivation device. The device comprises a solution dispenser, field planting baskets with a liquidstorage function and closed cultivation pots. The solution dispenser is arranged at the top end, each closed cultivation pot comprises a bottom cover, upper covers and planting cups, the bottom coverand the upper covers have seal assembling, each planting cup is arranged on one upper cover, each planting cup is arranged obliquely, one field planting basket with the liquid storage function is placed in one planting cup, the top surfaces of the upper covers and the bottom surface of the bottom cover are separately provided with a plurality of limit overflow openings, the closed cultivation potsare overlapped from the top to the bottom, and limit overflow openings arranged in the top-end closed cultivation pots are located directly below outlets of the solution dispenser. The device provided by the invention has a three-dimensional cultivation structure, so that a sunlight utilization rate of plant growth can be improved; the device has an overlap-type drip irrigation structure, so thata solution fully absorbs oxygen in air in the circulation process; the device has an overlap-type drip irrigation and the deep flow channel structure, so that from the perspective of growth characteristics of plants, a water absorption function of a tap root system and respiration of lateral roots of the plants can be fully taken into account.

Description

technical field [0001] The invention relates to a soilless cultivation technology, in particular to a three-dimensional superimposed deep channel drip irrigation soilless cultivation device. Background technique [0002] Current soilless cultivation techniques usually include the following methods: [0003] 1. The flat deep flow channel (DTF) has good planting stability and consumes very little energy. It is currently the most reliable and efficient soilless cultivation technology. Disadvantages: it occupies a large area and the plant root system needs continuous oxygenation , the utilization rate of sunlight / artificial supplementary light is low, and the output per unit area is limited. Manual operation is a lot of work; [0004] 2. The nutrient film type shallow flow channel (NTF) has good planting stability, low energy consumption, and high sunlight utilization rate. It is an emerging three-dimensional NTF soilless cultivation technology. It has a simple structure and a...

Problems solved by technology

[0003] 1. The flat deep flow channel (DTF) has good planting stability and consumes very little energy. It is currently the most reliable and efficient soilless cultivation technology. Disadvantages: it occupies a large area and the plant root system needs continuous oxygenation , the utilization rate of sunlight / artificial supplementary light is low, and the output per unit area is limited

Manual operation is a lot of work;

[0004] 2. The nutrient film type shallow flow channel (NTF) has good planting stability, low energy consumption, and high sunlight utilization rate. It is an emerging three-dimensional NTF soilless cultivation technology. It has a simple structure and a smaller footprint than DTF. , Disadvantages: continuous water pump supply is required, the appearance is poor, professional maintenance is required, and pipeline maintenance is difficult;

[0005] 3. Vertical aeroponics is a relatively new soilless cultivation technology in the world. It covers a small area, has a high yield per unit area, and has a high sunlight utilization rate. It is an emerging three-dimensional soilless cultivation technology. Disadvantages: complex structure, infusion capacity High consumption, high noise, the spray head is very easy to block, professional maintenance is required, and pipeline maintenance is difficult;

[0006] 4. The three-dimensional pipe drip irrigation technology is a relatively new soilless cultivation technology developed in China. It covers a small area, has a high yield per unit area, and has a high utilization rate of sunlight. It is currently a new three-dimensional soilless cultivation technology suitable for families. Disadvantages: equipment installation Difficult, because there is no liquid storage function, a continuous liquid supply system is required, the solution distributor at the upper end of the pipeline is easy to block, resulting in uneven liquid supply, and the inclination of the pipeline can easily affect the normal growth of plants, making pipeline maintenance difficult;

[0007] 5. The shelf-type soilless cultivation is a three-dimensional cultivation technology developed based on the flat deep channel technology. It occupies a small area and has a high yield per unit area. Disadvantages: it is difficult to install equipment, and there is a demand for the installation site, because the shelf-type structure It affects the lighting of plants, so the utilization rate of sunlight is not high or artificial lighting is required. The system needs continuous solution oxygen supply to ensure the normal growth of plant roots.
