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...
