Embodiment Construction

[0045] Please refer to the attached figure 1 , 2As shown, the light effects of five light-emitting diodes of the present invention in the soilless cultivation root system environment are different, but the device structure is the same in the five devices. The basin and the water circulation system 12 are composed, the dripper 1 accepts the water pumped up from the bottom basin 12, i.e. the nutrient solution, and the central axis 5 of the plastic pipe is installed in the bottom basin 12, and the central axis 5 penetrates the dripper 1, the pot 7 and the Bottom basin 12, submersible pump 16 is put into the bottom basin 12, the drainage pipe 15 of the submersible pump is connected with 1 three-way interface, and one interface enters the central shaft 5 through the water supply hose 13 and is connected with the dripper 1 at the upper end, and the water supply The hose 13 is connected to the pump and the drip head, the central axis 5 passes through the drip head, the pot and the b...

Abstract

An optical effect of LED in root system environment of soiless cultivation is disclosed. Its equipment is composed of dripping head, basins, lighting system, base basin, water circulation system with immersible pump in it, plastic tube as central axis, and LED boards arranged under said basin, in which the plant is growing via the holes on its bottom. Its method is use of the LED as light source to directly radiate the root system of plant.

Description

Technical field [0001] The invention relates to illumination measures in plant cultivation technology, in particular to the light effect of a light-emitting diode in the root system environment of soilless cultivation. Background technique [0002] Illumination is one of the indispensable and alternative environmental conditions during plant cultivation. Usually, the artificial light source used to irradiate plants is installed in an appropriate position in the upper space, because the leaves and stem tips of the plant's photoreceptors are all opened upwards to receive light. [0003] The root of the plant has the characteristic of growing downwards, and it grows in the dark during the plant's life without needing light. So far we have not seen the work of giving the root light during cultivation to obtain a positive effect. [0004] There is no light in the growth environment of the root, which does not mean that the root growth does not need light. It is generally believ...
