Abstract
The article considers the application of light-converting polymer films as cover materials for the cultivation of greenhouse crops in a covered soil. We analyse the impact of increasing the level of photosynthesis-active radiation (PAR) level in a greenhouse depending on the season, latitude, the angle of the sun, duration of daylight and on other parameters. The article presents some results of growing crops in greenhouse facilities located at the latitude of Moscow region. The results include a significant shorter vegetative stage, as well, as substantial increase in yield from 30 to 100 % in comparison with the reference conditions.
