摘要
本文采用优化综合评价系数法,对北京市密云县东关大队杏园主栽品种串枝红杏,在不同修剪强度下的幼树1a生枝修剪反应进行了综合分析研究。研究表明:在品种、年龄、环境、管理等条件一定的情况下,根据同一类枝条的基部粗度确定修剪量,可以比较合理地调节幼树主、侧延长枝与结果枝之间的关系,使树体生长旺盛,并能培养出足够数量的短果枝,为幼树的早期丰产及稳产打下基础。
In this Paper, the comprehensive optimum appraisal coefficient method is used to study the response of annual shoot of young apricot trees to pruning of various intensities. The result demgnstrates that u-sing the diameter at branch base to determine pruning intensity could a-djust the relationship between leading shoots, lateral branches and fruit shoots under the precondition of given variety, age, environment and management. In this way, the trees can grow vigorously and bear more fruit shoots, laying a foundation for early fruiting, high and stable ye-ild.
