The invention discloses an imitating wild condition planting method of dendrobium officinale. The method comprises the first step that a site is selected, wherein a primeval forest which is convenient in transportation and is free of industrial pollution in 100 kilometers nearby serves as a planting site; and the second step that the site is cleaned, wherein weeds in the primeval forest are removed, and roads are constructed and facilities used for spraying water and fertilizer are installed in the primeval forest. The imitating wild condition planting method of the dendrobium officinale can at least improve the rate of survival of the dendrobium officinale and improve the market supply of the dendrobium officinale.

The invention relates to an air conditioning system and a control method, in particular to an air conditioning system and a control method based on alpine fresh air as a source of fresh air. The system includes five parts: fresh air monitoring subsystem, fresh air collection subsystem, power subsystem, distribution subsystem and user terminal system. In another aspect, the present invention also provides a method for controlling the system. The method comprises: a fresh air collection step, a fresh air delivery step, a fresh air entering a room and an air conditioner for combined use, and a whole-process air monitoring step. The invention transports the fresh air rich in negative oxygen ions from the alpine virgin forest area to the user's air-conditioning unit and uses it as air-conditioning fresh air, which can alleviate the problem of indoor air pollution and greatly improve the breathing environment of urban residents under the ravages of smog; in addition, the present invention The implementation of the invention can also reduce the construction investment of the air-conditioning fresh air unit, and effectively solve the problem of bacterial growth in the fan coil unit, thereby generating huge social and economic benefits.
