The invention relates to the technical field of cultivation devices, and discloses an environment-friendly circulating agricultural seed cultivation device, which comprises a device body. An operation chamber is arranged in the device body, a cultivation chamber is arranged on one side of the operation chamber, a
nutrient solution box is arranged outside the operation chamber, an
electric heating wire is arranged at the bottom of the
nutrient solution box, and a first motor is arranged on one side of the
nutrient solution box. One end of the first motor is connected with a stirring shaft, stirring paddles are arranged on the
peripheral side of the stirring shaft, a
thermometer is arranged in the
nutrient solution box, a liquid conveying
pipe is arranged outside the
nutrient solution box, and one end of the liquid conveying
pipe is connected with a pump body. According to the environment-friendly circulating agricultural seed cultivation device, by arranging a
nutrient solution heating and stirring structure, the uniformity of the
heating temperature of a nutrient solution is improved, traditional electric heater heating is replaced by blowing-in air flow heating, the uniformity of the cultivation temperature is guaranteed, and by arranging an auxiliary lighting device, light supplementing and lighting are conducted.
Photosynthesis of seeds is promoted, and seed growth is accelerated.
