  Tags: illuminating plants alternating irradiation photosynthesis productivity protected soil plants energy-saving in electrical engineering technologies
  Description

  The article deals with the issue of alternating irradiator installation for growing plants in protected soil. The point of the method of illuminative installation con-sists in periodical influence of relatively high irradiance upon plants against a background of constant influence of relatively low one. It reduces plant radia-tion irregularity, improves the quality of agricultural products and cuts down energy-output ratio of growing processes.
