摘　　要：以5个不同海棠品种为试材,选取平邑甜茶为砧木,分别对海棠生长量及叶片营养进行测定,研究了重茬土对相同砧木不同海棠品种生长的影响。结果表明:同一块重茬地中,相同砧木不同海棠品种生长量及叶片矿质营养含量存在一定的差异;E5和E24品种生长存在优势,可作为抗重茬品种进一步培养。The study was conducted to research the influence of different crabapple cultivars＇ growth which were planted in continuous cropping soil.Five crabapple cultivars had been grafted on M.hupehensis stocks as the test samples,the growth and the leaf＇s mineral nutrient were determined.The results showed that in the same continuous cropping soil,different crabapple cultivars had the different growth and the different mineral nutrition contents.The cultivars of E5 and E24which had the growth advantages,could be further developed as resistant plants.
