Soilless culture device and method thereof

Abstract

The invention relates to the technical field of agriculture, in particular to a soilless culture device and a method thereof. The soilless culture device comprises a water supply system and a plantation system. The water supply system comprises a water pump 1, a water storage device 2, water inlet pipes 3 and water drainage pipes 4. The water pump is arranged in the water storage device. The plantation system comprises a water trough 5, a bracket 6 and plantation pots 7. The bracket is arranged on the water trough. The plantation pots are fixed onto the bracket. Two ends of each water inlet pipe are communicated with the water pump and the water trough. Two ends of each water drainage pipe are communicated with the water storage device and the water trough. Overflow holes 8 are arranged in the water trough. The height of each overflow hole is the same as that of the necessary irrigation water level. The overflow holes are communicated with the water drainage pipes. The bottom of the water trough is provided with water drainage holes communicated with the water drainage pipes.The soilless culture device and method thereof have following beneficial effects: the soilless culture device is scientific and reasonable in irrigation mode, significant in irrigation efficiency, little in maintenance, long in service lifetime, coherent in water absorption of plants and low in requirement for water quality.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to a soilless cultivation device and a method thereof. Background technique [0002] Soilless cultivation uses peat or forest humus, expanded vermiculite and other light materials as substrates to fix plants, allowing plant roots to directly contact nutrient solution, and adopts modern seedling raising technology of mechanized precision seeding, including hydroponics, mist (Air) cultivation, matrix cultivation. Soilless cultivation is a cultivation technique that uses nutrient solutions containing essential elements for plant growth and development to provide nutrients without using natural soil, so that plants can normally complete the entire life cycle. By the 1930s, this technology began to be applied to agricultural production. In the 19th century, W. Knop and others invented this method, and people further improved the technology in the 21st century, making soill...

AI Technical Summary

Problems solved by technology

[0006] The cultivation tank used is a tank with two closed ends made of a material with certain mechanical strength. Generally, three-dimensional cultivation is used to fix the cultivation tank to a specific support to maintain stability, thus limiting the mobility of the cultivation tank.

[0007] 2. Low degree of mechanization

[0008] Generally, in order to reduce costs, the length of the cultivation tank is large and fixed on the support. The filling and replacement of the cultivation substrate can only be done manually or semi-mechanized, which is time-consuming and laborious, and is not conducive to mechanized operation.

[0009] 3. Single harvesting method

[0013] Due to the poor external drainage of bag cultivation, it is inevitable to accumulate nitrate nitrogen fertilizer (ammonium nitrogen fertilizer will poison plants) when topdressing regularly, resulting in high nitrate content in finished vegetables, which is not good for food safety

[0014] 2. High dependence on hydropower

At present, a few types of drippers with large channel, small flow rate and better anti-clogging performance have been developed. With the deepening of research, the problem of dripper clogging will be gradually improved, but it is almost impossible to completely solve it.

[0019] 2. Salt accumulation

[0021] 3. The later maintenance cost is higher

[0022] After one batch of planting is completed, the drip irrigation head must be pulled out (or the micro-irrigation pipe) when treating the substrate, and then the substrate is treated. After the substrate treatment is completed, the drip irrigation head must be reinserted (or the micro-irrigation pipe should be laid again) , increased labor costs and time costs

[0023] 4. Due to the long pipe guide, the pressure of the dropper is uneven, resulting in uneven water outlet and inconsistent water required by plants.

[0025] 1. Impossible to irrigate accurately, and the uniformity of irrigation is poor. Since it is a device used in soilless cultivation (matrix cultivation) instead of planting on ground soil, it is very important for the accuracy and uniformity of irrigation.

[0026] 2. The water quality is poor. The maintenance methods in the prior art adopt spraying or drip irrigation, which may cause uneven water supply, more or less
