Influence of polyethylene mulching film of different color and thickness on pine strawberry varieties’ yield

Experiments were carried out in 2018-2020 the FSBSI “FSC named after I. V. Michurin” (Michurinsk, Tambov region) to check influence of polyethylene mulch different colors and density on yield pine strawberry varieties (Fragaria x ananassa Duch). The experiment was established following rows mulching options with film produced Spain: 1. Black, 60 μm (control); 2. 30 density; 3. White black, density. Allocation is random. Number plants per plot - 25. Plants five studied ‘Vima Kimberly’ (control), ‘Alice’, ‘Malwina’, ‘Fliar’, ‘Fleurette’, which planted by “frigo” seedlings a diameter up 15 mm 80 cm width, height, distance between two lines 40cm row 30cm. analysis experimental results showed that each fruiting year higher obtained option black μm. Comparative assessment reliably high from ‘Fleurette’ variety years experiment: 18.2%, 68.4% 51.6% compared Vima Kimberly variety. In white film, 2 6 days later onset ripening phenophase timing control noted, due lower soil temperature under materials during development plants.
