在“以粮为纲,全面发展” 的方针指引下,一九五九年以来,我场先后栽植梨树三万余株。十年间为市场提供了鲜果四百余万斤,为丰富城市人民生活,促进工农业生产做出了应有的贡献。但在建场初期,由于缺乏经验,忽视了梨树品种的地区适应性,至今出现了一些低产劣质的品种,在一定程度上影响了果园总产量的提高。为了尽快地解决大树不结果,投资不见收益的矛盾,遵照毛主席“有了优良品种,即不增加劳动力、肥料,也可获得较多收成”的教导,自一九六八年起,我们边试验边推广,对几个不适应本地区栽培的品种,如砀山苏梨、莱阳慈梨、平头青和西洋梨中的法兰西等,采取了高接换种措施。先后换种的梨树达五千株,
Guided by the principle of “taking grain as the key link and all-round development”, since 1959, we have planted more than 30,000 pear trees. In the ten years, the market provided more than 400,000 kilos of fresh fruit, making due contributions to enriching the urban people’s life and promoting industrial and agricultural production. However, due to lack of experience, ignoring the regional adaptability of pear varieties at the early stage of establishment, some low-yielding and poor-quality varieties have emerged to some extent, thus affecting the total output of orchards. In order to resolve as soon as possible the contradiction between the ineffectiveness of the tree and the return of investment, comply with Chairman Mao’s teaching that "with excellent varieties, that is, more harvests can be obtained without increasing labor force and fertilizer, since 1968, we Tests while promoting the spread of several varieties not suitable for cultivation in the region, such as 砀SanShu pear, Laiyang Ci pear, flat-headed green and pear in France, adopted a high exchange of species measures. Has changed another kind of pear tree 5000,
