一、我市苹果生产的现实我市的苹果生产,始于五十年代中期,截止1984年,苹果栽培面积已发展到八万余亩,151万株,约占全市果树总面积的1/4。栽培品种多是三、四十年代的老品种,如国光、红玉、倭锦、普通金冠、元帅等。这些品种,在我市表现单产低、品质差、经济效益不高。且由于立地条件的影响,树体多表现贪青徒长、幼龄期长、不能适龄结果。在正常管理的情况下,一般定植七、八年后,才开始结果(元帅系表现尤为突出)。进入盛果期时间不长(十七、八年生),树体又很快的向衰老转化。从市场需要来看,苹果在我市担负着市场六个月以上的果品供应,而我市年产苹果仅两千五百万斤左右(1984年统计),自给
First, the reality of apple production in our city Apple production in our city began in the mid-1950s. As of 1984, the apple cultivation area has grown to more than 80,000 mu and 1.51 million, accounting for 1/4 of the total area of the city’s fruit trees . Cultivars are mostly old breeds in the 1930s and 1940s, such as Guoguang, Hongyu, Japanese Kam, ordinary golden crowns, marshal and others. These varieties, in our city show low yields, poor quality, low economic benefits. And due to the site conditions, the performance of the tree more corvee growth, young age, can not age results. In the case of normal management, the general colonization of seven or eight years before the results began (Marshal Department performance is particularly prominent). Into the fruiting period of time is not long (seven or eight years of age), the tree quickly transformed into aging. Demand from the market point of view, Apple is responsible for the market in the city more than six months of fruit supply, and the city only produces about 25 million pounds of apples (1984 statistics), self-sufficient
