Analysis of the Causes of Apple Replanting Obstacles and Comprehensive Management Strategies
摘要
Abstract
Replant obstacle in mountainous orchards is an important factor restricting the sustainable and healthy development of the fruit industry.Apple trees under replant conditions exhibit slow growth,poor root development,weakened vigor,and even death,severely affecting yield and fruit quality.Causes of apple replant obstacle mainly include soil microecological imbalance and pathogen accumulation,in which pathogenic fungi such as(Fusarium spp.)proliferate extensively and inhibit apple root growth;deterioration of soil physicochemical properties,including soil compaction,increased bulk density,and reduced porosity,which restrict root extension and soil microbial activity,reduce soil water and nutrient retention capacity,and lead to mineral nutrient imbalance,and toxic substances such as phlorizin and benzoic acid produced after transformation of apple root exudates by soil microorganisms,which promote pathogen proliferation and inhibit the growth of newly planted young trees.To address these issues,comprehensive management strategies are proposed,including soil ecological restoration and disinfection,biological control and microbial regulation,scientific fertilization and nutrient management,and the selection of resistant rootstocks and optimization of cultivation management.These strategies provide scientific evidence and technical support for promoting high-quality and sustainable development of the mountainous apple industry in China.关键词
