苹果树初结果时的产量和枝叶量密切相关,在乔砧密植条件下,为达到早成形,早结果的目的,采用有效的技术措施来增加其枝叶量,是十分必要的.山东省五莲县近几年新建良种苹果园5600多公顷,由于肥水投入大,致使幼树长势旺而结果少,前几年采用春刻芽、夏环剥、秋拉枝等技术,虽收到了一定效果,但也出现了不少问题,在当地啥时间应用这些技术效果最好.为此,自1993—1996年我们在全县18处乡镇对3—5年生红富士、新红星和首红等品种进行试验,现总结如下:
Apple tree early results are closely related to the yield and the amount of branches and leaves, planting angels under conditions, in order to achieve the purpose of early shape, early results, the use of effective technical measures to increase the amount of its branches is very necessary. Wulian in Shandong Province In recent years, the county has newly built over 5,600 hectares of elite apple orchards. Due to the large input of fertilizer and water, the young trees grow vigorously and the results are few. A few years ago, they adopted some techniques such as spring carving buds, However, there are also many problems that have arisen in the light of the local application of these technologies.For this reason, from 1993 to 1996, we conducted the research on varieties of red Fuji, new red star and first red in 3-5 townships in 18 prefectures Test, are summarized as follows:
