本研究以亩产8000～10000斤的高产园为试材,于莱阳、栖霞、海阳及本院农场连续进行7年试验。结果表明:茌梨高产稳产园群体结构指标是,营养面积利用率不低于70%,树冠交接率5～10%。亩枝量8～10万间,总叶量达35～40万片,叶面 In this study, a high-yielding garden of 8000-10000 kg per mu was used as the test material, and 7 consecutive years of trials were conducted in Laiyang, Qixia, Haiyang and our hospital farms. The results showed that the population structure index of high and stable peach pear population was not less than 70% and 5 ~ 10% for crown crown yield. The amount of acres of branches 8 to 10 million, the total leaf volume of 35 to 400,000, foliar
