摘 要:苹果水心病是一种果实生理病害,在所有苹果的栽培生长区域均有发生。品种、果实成熟度、温度、栽培条件、果实大小、矿质营养、贮藏条件等因素影响苹果水心病的发生。目前其无损检测的主要方法有光密度法、X-射线法、质量密度法和磁共振影像法。补充钙素营养、增施有机肥、适时采收、合理修剪等是防治苹果水心病的关键措施。Apple watereore is a kind of fruit physiological diseases, occurring in all apple producing areas. Many factors, such as apple cuhivar, fruit maturity and size, temperature, the cultivated conditions, soil mineral content, storage condition, can affect the severity of apple watercore. Currently the main methods nondestructively detecting this disorder are optical density method, X-ray method, mass density method and magnetic resonance imaging (MRI) method. The key measures for prevention of apple watercore disease are replenishing calcium nutrition,increasing level of organic fertilizers,harvesting in proper time and reasonably pruning and so on.
