Using LED lamps in cultivation of mulberry nurseries

Abstract

The analysis of results carried out on revealing the efficiency of using in night LED lamps three, namely red, blue and white colors for increasing growth and development of mulberry nurseries in the greenhouse conditions has been presented. It has been shown that using LED strips improves growth and development of nurseries on in height, leaves quantity and width of nurseries. Moreover, the development degree of nurseries differs on the control variant weakly in case of red lighting one at the same time in the blue and white lighting variants it is essential. The maximal growth of nurseries on height in comparison of control variant in case of white lighting was to 25.0 %, and the minimal one corresponds to case of red lighting, 1.9 %. The average growths of nurseries for a season was 3.3, 13.2 and 15.5 % in cases of red, blue and white lightings, correspondingly. The relative growths of nurseries on the height for a season compared beginning of the experiences were 133.3, 140.0, 163.3 and 170.0 % in cases of control and also led, blue and white lighting variants, accordingly. The most quantity of leaves in case of white lighting variant was 44.4 % more than control one and the least quantity corresponds to the red lighting variant, 8.8 %. The average values of this quantity for a season were 5.7, 21.9 and 24.3 % for red, blue and white lighting variants, correspondingly.

Improving the method for selecting elements of an automated electrical device

“…When an element is selected based on the algorithm and the initial data is entered into the program, the program examines the elements included in the database based on the given conditions and selects the most optimal option. Conditional functions of device selection are included in the algorithm, and as a result of their execution, mutual compatibility of the selected elements is ensured [7][8][9][10][11][12][13][14][15].…”
