The invention relates to a biological information microwave acquisition method and a life information field guiding instrument and an application thereof, belongs to the new technical field of the medical treatment instrument combing health care and remedy, and also belongs to the new technology field of the breeding. An acquisition object is arranged on the life information field guiding instrument in the invention, the required distance is adjusted within 3 cm, a switch is opened, a life body starts to rotate, a life information microwave sent out by the acquisition object is acquired to the life information field guiding instrument, and is sent to a receiving object together with a frequency conversion electromagnetic wave in a microwave oscillation energy adding device through a microwave emitter, and the distance between the microwave emitter and the receiving object is within 8cm. The guiding instrument of the invention is characterized by environment friendliness, extremely low manufacture, use and energy consumption cost, obvious curative effect, small volume, simple operation, convenient and safe use, short health care time, strong pertinence, quick effect, etc. The guiding instrument is suitable for being used in medical care departments and households, and is convenient for being popularized and promoted, and has obvious social benefit and economic benefit.
