The purpose of this paper is to investigate the effect of a combination of reflective film mulching (RFM) and shading treatments on the growth of carnation at high temperatures. Combination of RFM and shading treatments increased plant height, length of primary and secondary branches of carnation seedling. Moreover RFM prolonged the harvest period by advancing flowering by approximately 1 month, which resulted in the increase of the cut flower yield. The number of cut flowers harvested in the first 3 months of the harvest period increased from 33 to 107% compared to the non-mulched plots (over 2 years), and total yield (harvested until May in the next year) increased by 15%. The optimum results were obtained when the shading period was limited to 2 months in midsummer, and a longer shading period decreased the yield as a result of reduced solar radiation. The beneficial effects of RFM on carnation growth were revealed, namely lowering of soil temperature in midsummer and supply of solar radiation to the low to middle leaves from the reflective surface.
