Research Progress on Soil Improvement and Green Fertilization Technology in Apple Orchards
PAN Weifeng
Abstract：Soil degradation,characterized by long-term continuous cropping obstacles,inappropriate fertilization,and improper tillage practices,has led to prominent issues such as physicochemical deterioration and reduced biological activity.This phenomenon has become a key bottleneck restricting the sustainable development of China's apple industry.This paper systematically reviewed the latest research progress on soil improvement and green fertilization technologies for apple orchards both domestically and internationally.In soil improvement,physical,chemical,and biological methods have all achieved remarkable results in enhancing soil structure,regulating pH value,and restoring microbial community diversity.Specifically,green manure planting comprehensively improves soil physicochemical properties,while pit water-fertilizer application achieves high water and nutrient use efficiency in dryland areas.Regarding green fertilization,techniques such as water-fertilizer integration,soil-testing based formula fertilization,and organic fertilizer substitution demonstrate excellent prospects for enhancing nutrient utilization efficiency and mitigating environmental pollution.Furthermore,the development and promotion of novel functional fertilizers,including selenium-enriched,slow-and controlled-release,and humic acid-based fertilizers,further advance fertilization management toward precision and ecological practices.
