LED stereoscopic domestic cultivation device capable of regulating nutrient solution depth

Abstract

The invention discloses an LED stereoscopic domestic cultivation device capable of regulating nutrient solution depth. The LED stereoscopic domestic cultivation device capable of regulating the nutrient solution depth is composed of a nutrient solution supply system, an LED illumination system, a cultivation system and a support frame (25). The nutrient solution supply system conveys nutrient solution to the cultivation system through a valve and a pipeline; the LED illumination system provides light for the cultivation system for the plant growth. The cultivation system comprises planting compartments (2), planting plates (3), plant planting sponge (4) and water temperature regulating heating wires (5). An LED light source (1) is arranged above each planting plate. The nutrient solution supply system comprises a nutrient solution box (18), a connecting pipe (16), a main control valve (17), a check valve (15), a side solution box (7), an overflow pipe (9) and a surplus solution recycling box (11). The LED stereoscopic domestic cultivation device capable of regulating the nutrient solution depth can automatically complement nutrient solution without electricity, deep solution flow, shallow solution flow and deep and shallow solution combination modes are realized in the same nutrient solution system, and the plant can obtain complete nutrition. The LED stereoscopic domestic cultivation device capable of regulating the nutrient solution depth is labor saving, simple, safe and suitable for household planting.

Description

technical field [0001] The invention relates to an LED three-dimensional household cultivation device for adjusting the depth of nutrient solution, which belongs to the technical field of plant cultivation. Background technique [0002] Soilless cultivation is the use of nutrient solution to cultivate crops through certain cultivation facilities. Soilless cultivation has the characteristics of cleanliness, sanitation, high yield and good quality. After years of development, soilless cultivation has been widely used in agricultural production and has become an indispensable part of our facility agricultural cultivation. In recent years, soilless cultivation has gradually penetrated into the family, and has become the main way of planting plants at home. [0003] At present, hydroponics methods are mainly divided into deep liquid flow hydroponics and shallow liquid flow hydroponics according to the depth of nutrient solution. Deep liquid flow hydroponics require...

AI Technical Summary

Problems solved by technology

Deep liquid flow hydroponics requires a deep nutrient solution layer, a large amount of water, less oxygen, and needs to be circulated to increase oxygen; shallow liquid flow hydroponics has a shallow nutrient solution layer and requires a continuous supply of nutrient liquid film. The two methods of nutrition The supply of liquid needs to rely on electricity for circulation. There are following problems in long-term use: First, there are many components and the device is more complicated. Nutrient solution circulation needs to add multiple components such as water pumps, liquid supply pipes, and return pipes, and the connection between pipes Better sealing is required, if it becomes loose, it will cause leakage of the nutrient solution; the second is power consumption, the nutrient solution in deep hydroponics needs to be circulated for 0.5 hours every 3-4 hours, while the nutrient solution in shallow hydroponics is always circulated, requiring It consumes a lot of electricity, and once there is a long-term power outage, the deep liquid flow hydroponics is likely to cause hypoxia in the root system of the plant, and the supply of the thin water layer in the shallow liquid flow hydroponics is interrupted, and the root system is prone to lack of water and dies; the third is inflexibility. At present, household hydroponic devices can only use a certain fixed liquid level to cultivate plants, such as single deep liquid flow hydroponics or shallow liquid flow hydroponic cultivation methods, and hydroponic plants are different due to different plant types and the growth of the plants themselves. Different growth periods require different amounts of water and nutrients for individuals, requiring different amounts of nutrient solution
