【摘要】 瑞雪和瑞香红是西北农林科技大学选育的优良晚熟苹果新品种，果形端正，甜酸适度，风味浓郁，耐贮藏，深受消费者喜爱。调查了瑞雪和瑞香红在陕西千阳、宁夏彭阳、四川盐源等三地的结果情况。结果表明，瑞雪适应性最强，在水地、旱地和高海拔地、低海拔地均可以栽培，但要注意预防苹果黑星病和果锈的发生，套袋栽培效果更好。瑞香红在高海拔、无灌溉条件的地区要慎重发展，因果实小导致产量低、效益下降；在中低海拔（1 000 m以下）地区可以栽培，但要注意施肥和多灌水，以保证优质、高效，可以免袋栽培。更多还原

【Abstract】 AAbstract ‘Ruixue’ and ‘Ruixianghong’ are excellent late-maturing apple new varieties selected by Northwest A&F University. The fruits are regular in shape, with moderate sweetness and acidity, rich in flavor and good in storage, and are deeply loved by consumers. The fruiting situations of ‘Ruixue’ and ‘Ruixianghong’ in Qianyang of Shaanxi, Pengyang of Ningxia, Yanyuan of Sichuan etc. three places were investigated. The results showed that ‘Ruixue’ had the strongest adaptability and could be cultivated in irrigated land, dry land, high-altitude areas and low-altitude areas. However, attention should be paid to preventing the occurrence of apple scab and fruit rust.Bagging cultivation had better effects. ‘Ruixianghong’ should be developed carefully in high-altitude and non-irrigated areas because the small fruit leads to low yield and decreased efficiency. It can be cultivated in middle and low-altitude(below 1,000 m) areas, but attention should be paid to fertilization and more irrigation to ensure high quality and high efficiency, and bagless cultivation can be adopted.更多还原
