A hanging trough substrate cultivation system and method

Abstract

The invention discloses a system and a method for culturing a suspended groove type substrate. The system comprises a water-fertilizer integration device, a plurality of suspended culture grooves andculture substrates arranged in the suspended culture grooves, wherein each suspended culture groove comprises a pair of vertical supports, a pair of transverse supporting rods and an arc-shaped planting groove; two ends of the transverse supporting rods are respectively fixed to the corresponding vertical supports; two opposite side edges of the arc-shaped planting grooves are respectively connected with the corresponding transverse supporting rods; groove bodies are in a concave-convex body shape, with concave parts and convex parts in staggered distribution; the water-fertilizer integrationdevice comprises nutrient solution storage barrels, water pumps, filters, nutrient solution conveying pipes and drip irrigation pipes which are sequentially connected. The method comprises the following steps: putting the culture substrates in the suspended culture grooves, embedding electric heating wires in the culture substrates, planting crops in the culture substrates, and putting the drip irrigation pipes on the top surfaces of the culture substrates; during a production period of the crops, enabling nutrient solutions in the nutrient solution storage barrels to be quantitatively drip-irrigated into the culture substrates at regular time by the water pumps, the nutrient solution conveying pipes and the drip irrigation pipes.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a hanging substrate cultivation system and technology. Background technique [0002] Soilless culture is a method of using other materials instead of natural soil to cultivate plants without using natural soil, including hydroponics, mist (air) cultivation, and matrix cultivation. In the mid-19th century, W. Knop and others invented this method. By the 1930s, this technology began to be applied to agricultural production. In the 21st century, people further improved the technology, making soilless cultivation develop. [0003] In soilless cultivation, artificially prepared culture solution is used to supply the needs of plant mineral nutrition. Soilless cultivation is a kind of nutrient solution containing essential elements for plant growth and development without using natural soil to provide nutrition, so that plants can normally complete the entire life cycle. ...

Problems solved by technology

[0004] The existing general cultivation tank basically adopts circular or square metal tube as the support material of the tank body, and uses metal plate, plastic plate, non-woven fabric or woven cloth as the material to form the tank body material, and the connection and installation method between the two more complex

The ventilation and water permeability of the tank material is poor, the cultivation substrate lacks scientific and clear physical and chemical indicators, the cost performance of the nutrient composition of the nutrient solution needs to be improved, the controllability and practicability of the water and fertilizer integration device are not enough, and the heating device of the cultivation substrate may not be equipped. , or more complex
