Abstract: In order to probe into the relevant conditions of the large-scale cultivation of different varieties of red pear,and to provide the theoretical basis and technical support for the introduction and large-scale cultivation of red pear varieties in Shangshui County,Henan Province,comparative experiments were conducted on the phenological period,fruit economic characters,growth and fruiting habits and content of fruit contents of five main introduced varieties of Hongli(Hongxiangsu pear,Yuluxiang pear,Xinli No.7,Mantianhong pear and pink Xiangmi pear). The results showed that all the five main cultivars could complete the annual growth cycle in Zhoukou. Among them,Xinli No.7 belonged to early maturing variety,Hongxiangsu pear and Yuluxiang pear belonged to middle maturing variety,Mantianhong pear and pink Xiangmi pear belonged to late maturing variety. According to the fruit yield and nutritive value,the middle-late maturing variety was better than the early maturing variety. In large-scale cultivation of red pear,priority should be given to the development of late maturing varieties pink Xiangmi pear and Mantianhong pear,moderate development of middle maturing varieties Hongxiangsu pear and Yuluxiang pear,and appropriate development of early maturing variety Xinli No. 7.

摘要： 为探讨红梨不同品种规模化栽培的有关情况，为当地红梨新品种引进、规模化栽培提供理论依据和技术支撑，在河南省周口市商水县对引进的5个红梨主栽品种红香酥梨、玉露香梨、新梨7号、满天红梨和粉红香蜜梨的物候期、果实经济性状、生长结果习性和果实内容物含量等方面进行规模化栽培对比试验。结果表明：5个主栽品种在周口地区均能正常完成年生长周期。其中，新梨7号属于早熟品种，红香酥梨和玉露香梨属于中熟品种，满天红梨和粉红香蜜梨属于晚熟品种。从果实产量和营养价值方面综合考虑，中晚熟品种较好，早熟品种相对较差。在红梨规模化栽培上，应当优先发展晚熟品种粉红香蜜梨、满天红梨，适度发展中熟品种红香酥梨、玉露香梨，适当发展早熟品种新梨7号。
