摘要
以‘武植3号’中华猕猴桃为试材,研究了广东省和平县猕猴桃果园土壤的主要营养状况及其对果实品质的影响。结果表明:土壤营养因子与果实品质之间存在着不同程度的相关性,多元线性回归分析结果表明,在一定范围内,果实可溶性糖、可溶性固形物和固酸比与土壤有机质呈正相关。Vc含量与土壤有机质含量呈线性正相关,与碱解氮呈负相关。土壤养分对猕猴桃果实品质影响较大,在土壤管理过程中可以根据果实品质要求,科学地制定相应的施肥方案。
Influences of orchard soil nutrient on fruit qualities of Actinidia chinensis ＇ Wuzhi No. 3 ＇ in Heping County, Guangdong Province, China, were studied. The results showed that the correlations with different extent between main soil nutrients and fruit quality were present. The multiple linear regression analysis revealed that soluble solids, soluble sugar in the fruit were positive correlative to the soil organic matter. The vitamin C content in the fruit was positive correlative to the content of soluble solids, but negatively correlative to the content of available N. These results showed that the soil nutrient status greatly influenced quality of kiwifruit. The scientific and rational fertilizing scheme should be made based on the rela- tionship between fruit quality and soil nutrients.
