种植密度对近10年中国甜菜产质量的影响:文献计量与Meta分析
A Meta-Analysis on the Influence of Planting Density on Sugar Beet Production in China
摘要
Abstract
Sugar beet is a globally important sugar crop,and optimizing planting density is a key agronomic practice for achieving high yield and high sugar content.However,the relationship between planting density,yield components,and final sugar yield involves complex interactions.This study conducted a comprehensive meta-analysis by integrating 117 field experiment publications from 2016 to 2025.The results showed that:(1)In China,the planting density primarily ranged from 80,000 to 120,000 plants ha-1;the yield was mainly concentrated between 60 and 100 t ha-1;and the sugar content distribution was focused between 14%and 18%.(2)As planting density increased,the root yield per unit area showed a gradual upward trend,while the sugar content initially increased and then decreased.(3)The effect of planting density on yield varied significantly,while its overall impact on sugar content was primarily positive.In general,a density of 80,000 to 100,000 plants per hectare significantly enhances both Root yield and sugar content.In conclusion,optimizing planting density according to specific conditions in China's sugar beet production can enhance cultivation benefits and promote the sustainable and healthy development of the domestic sugar industry.关键词
