摘要
对从北京市怀柔县、密云县,辽宁省建昌县山区引来的300余株欧李进行了两年观察,结果表明,所引进的群体中,明显的存在着3种不同的类群,即扁果类群、圆果类群和长果类群。其中扁果类群为优良类群,果个最大,着色最早,色泽鲜红,果肉离核,可食部分最多,可溶性固形物含量较高,酸甜可口,浓郁芳香,既可鲜食又可加工。 欧李耐寒、耐旱、耐瘠薄土壤,对病虫害的抵抗力很强。扁果类群具丰产性,可适量发展。欧李植株矮小,红果绿叶,既可作盆景观赏,又可作庭院绿化,以扁果类群为佳。
Chises dwarf cherry (Bunge cherry) [Gerasus humilis (Bge.)Sok.(Prunus humilis Bge.,P.bungeiWalp.)], which had been introduced more than three hundred plants from mountain areas of Huairou and Miyun county in Bcijing and Jianchang county in Liaoning province, has been observed for two years. Results showed that in introduced plants there were three different types, flat, round and long fruits. Among them the flat type is the best, larger size, bright red colour and fragrant. The fruits of flat type are earler coloured, freestone, proper sweet and sour, higher solubility substance content and more flesh. This type is suitable for fresh market or processing.Other advantage of Chinese dwarf cherry is strong cold-resistance, drought-resistance, disease-resistance and insect-resistance. If it was grown in poor soil, it would produce heavy crop. Chincse dwarf cherry is suitable too for pot cultrue or home gardens become of is dwarf characteristics and attractive fruit.
