The invention discloses a solar independent irrigation light supplementary spiral cultivation upright which is composed of a water tank, a spiral cultivation trough, a solar panel nozzle, an upright body, a mini-type water pump, a wire, a liquid supply pipe and a storage battery. The outer surface of the solar panel nozzle is covered with a hemispherical solar panel, a cylindrical LED lamp tube is fixedly installed on the inner wall of a transparent column jacket, and the solar panel nozzle is respectively connected with the storage battery and the mini-type water pump through the wire and the liquid supply pipe which penetrate through the inner space of the cylindrical LED lamp tube. According to the solar independent irrigation light supplementary spiral cultivation upright, solar energy can be absorbed by the hemispherical solar panel and light energy can be converted into electric energy and stored by the storage battery in any season and at anytime, and power is supplied to the mini-type water pump or the cylindrical LED lamp tube by the storage battery, so that independent and automatic irrigation and light supplementary of the spiral cultivation upright are achieved without power consumption, the overall structure is simple and reliable, and the upright is convenient to disassemble and assemble. The solar independent irrigation light supplementary spiral cultivation upright can be used for independent cultivation upright light supplementary and irrigation outdoor or on a balcony or in a greenhouse without the requirement for power supply.
