| 摘 要： | 对大连瓦房店地区苹果苦痘病病害程度不同的红富士苹果果实进行了氮、磷、钾、钙、镁、铁、锰、铜、锌、硼、钼含量的测定。结果表明:苦痘病的病害程度与苹果果实内的含氮量呈极显著正相关关系,即苦痘病越严重,果实内的含氮量越高;苦痘病的病害程度与苹果果实内的氮/钙比呈极显著正相关关系,即果实内氮含量越高,钙含量越低,苦痘病越严重;病害程度与苹果果实内的钙/(钾+镁)比呈极显著负相关关系;病害程度与果实内的铜含量呈极显著正相关关系;病害程度与果实内的磷、钾含量无显著的相关关系。试验得出:苹果果实内氮含量过高,是导致苦痘病发生的重要因素。

| Abstract: | The contents of nitrogen,phosphorus,potassium,calcium,magnesium,iron,manganese,copper,zinc,boron,molybdenum were analyzed in fruits of Fuji apple trees which had different disease extent of apple bitter pit disease in Dalian Wafangdian region.The results showed that: The disease extent of apple trees were significantly positive correlated with the contents of nitrogen in fruits,that was,the more serious disease bitter pit,the higher contents of nitrogen in fruits;The disease extent of apple trees were signi... |
