Perennial Dicotyledonous Weeds Occurring in Peanut (Arachis Hypogaea L.) Crop Fields

This article analyzes the species composition, morphological characteristics, and bioecological features of perennial dicotyledonous weeds occurring in peanut (Arachis hypogaea L.) agrocenoses. Their biological development, distribution patterns, and competitive ability were evaluated. The study indicates that deep root systems and high ecological adaptability enhance weed persistence and adversely affect peanut productivity. The findings provide a scientific basis for effective weed identification and management in peanut agrocenoses.
