ResumoPolyethylene film mulching is commonly used in peanut (Arachis hypogaea L.) production, an important oil crop. Clear polyethylene film (CLEF) has previously been the only choice for all growing conditions. However, colored polyethylene film has been applied to the cultivation of crops in recent years, so testing the effects of colored film mulches on peanuts is necessary. In this study, we observed the effects of eight colored polyethylene films on devastating pest abundance, plant growth and yield, and soil conditions in peanut fields. The results showed that light-silver-gray film (LSGF), silver-black on both sides film (SGBF), and black film (BLAF) mulches were more effective in reducing the pest population (aphids, thrips, and mites) compared to plants mulched with other films. In addition, SGBF and LSGF mulching accelerated seeding emergence and benefited peanut growth, and the yield increased by about 20% compared to peanuts mulched with CLEF. The soil temperature and humidity under the LSGF and SGBF treatment were more suitable for peanut growth compared to the other film treatments. In conclusion, LSGF and SGBF mulches were appropriate choices for managing pests, maintaining optimum soil conditions, and increasing yield in peanut production.
