The invention relates to a solar high-temperature air-liquid combined drying system which is composed of a liquid heat collection part, a drying part and an air heat collection part; the liquid heat collection part and the air heat collection part are all provided with heat collection core pipes; the heat collection core pipes extend into a solar heat pipe and are connected with internal sleeves of the liquid heat collection part to form a heat collection unit, and a plurality of units are connected in series and then connected in parallel, thus the liquid heat collection part is formed; a liquid outlet pipe is connected with a liquid storage pool, and the liquid storage pool is connected to a liquid injection port of a drying machine; and water or oil can be injected in the liquid heat collection core pipe. Hot air with the temperature between 120 DEG C and 200 DEG C, and hot water or heat conduction oil with the temperature higher than 95 DEG C can be provided by the drying system; the hot air and the heat conduction liquid can be simultaneously applied to drying devices; and the rely on fossil fuel can be can be reduced greatly in areas which have solar energy utilization conditions, the energy saving effect is obvious, the use cost of the drying devices is lowered, and the aim of low-carbon emission can be achieved.
