红星苹果在我市栽培已有四十余年的历史。解放以后发展很快,到一九七六年已有18万余株,占我市苹果总数的40％以上,常年产量300余万斤。红星苹果的输导组织发达,幼树阶段比其它品种生长旺盛,分枝角度小,成花结果较晚,按一般品种管理,不容易实现高产稳产。主要应该培养好树冠,解决好主侧角度(主枝角度60-70度,侧枝角度大于主枝)及小枝角度,培养好各种类型的结果枝组,并使枝组在整个树冠中分布均匀,使树势逐步缓和下
Red Star apple cultivation in our city has more than 40 years of history. After liberation, it developed rapidly. By 1976, it had more than 180,000 strains, accounting for more than 40% of the total number of apples in our city and annual output of more than 300 million jin. Red Star apple conduction organization developed saplings than other varieties of vigorous growth, branch angle is small, late flowering results, according to the general management of varieties, is not easy to achieve high and stable yield. The main crown should be cultivated to solve the main side angle (main branch angle of 60-70 degrees, side branches angle greater than the main branch) and branchlets angle, cultivate various types of results Zhizu, and Zhizu group distribution throughout the crown , So that the tree gradually ease the next
