近几年来,青梅(Prunus mume Sieb.etZucc.)产量远远不能满足内销和外贸出口的需要,各地竞相恢复和发展青梅生产。但过去有关青梅的科研报道很少。青梅生产缺乏科学栽培管理的依据,亩产一直上不去。为此,我们于1983～1984年间在江苏、浙江等地进行了田间调查和试验,现将部分结果初报如下。一、青海的发枝规律 (一)青梅的发枝习性青梅在花后展叶抽梢。常熟8年生“细叶青梅”的萌芽率为88.3％,成枝数为3.75枝(指延长技剪口下发出的20厘米以上的枝数),说明青梅的萌芽率和成枝力均较强。一年生基枝顶端抽生长枝,上、中部抽生的枝条
In recent years, the output of Prunus mume Sieb.et Zucc. Has far failed to meet the needs of domestic sales and export of foreign products. However, there have been few reports on the research of plum in the past. Oolong cultivation lack of scientific basis for the cultivation and management, mu yield has been increasing. To this end, we conducted field surveys and experiments in Jiangsu and Zhejiang between 1983 and 1984, and some of the results are reported below. First, the law of the hair branch in Qinghai (a) Oregon habit of young plum Zhapi leaves after the show. Changshu 8-year-old “Slender leaf plum” germination rate of 88.3%, the number of branches 3.75 (extension of the technical scissors issued more than 20 cm under the branches), indicating the plum germination rate and branch force are strong . An annual branch of the top pumping growth of long branches, the upper, middle of the branches
