Information About Author:

The influence of the light correcting films of various compositions on vital activity of sprouts of cabbage was researched. For this purpose the technique of comparative trials was completed. The technique consists in cultivation of sprouts of cabbage in hothouses by a size 1x1x0,6 m, covered by different films with a control of plant's metrics. Is shown, that usage of films with various physical properties renders considerable influence on metrics index under them of cabbage's sprouts. The composition of the light correcting Alms permitting of cabbage's sprouts in a closed ground in locale of Western Siberia without padding heating and lighting and to reduce period of cultivation on 10-15 of days is defined.
