摘要
绵椒是临夏中北部半干旱区栽培的主要经济树种,开展绵椒选优对于提高绵椒栽培质量具有实际意义。本文叙述了绵椒选优区域、选优程序和选优细则,通过对72株初选优树的树木、立地、人为、环境等4大类因子的20个子因子的统计分析,确定各因子的得分权重和不同级别的得分值。经过初选、复选和终选,选出绵椒优树6株,并完成优树的调查和建档工作,对优树资源的利用提出了可行的途径。
Zanthoxylum bungeanum(Mianjiao)Maxim. is one of main economical tree species cultivated in north central semi-arid region of Linxia. It is of practical significance to improve cultivation quality by carrying out plus tree selection ofZ. bungeanum(Mianjiao)Maxim. This article narrated the region, procedure and regulation of plus tree selection ofZ. bungeanum(Mianjiao)Maxim. By analysing statistically 4 main factors such as tree, land, artificial factors and environment and so on and their 20 sub-factors of 72 primary selected trees, we identified score weight and different grades score. Through primary selection, re-selection and finally selection, we selected 6 superior trees and completed superior trees’investigation and work on building files and proposed the feasible approaches to use superior trees resources.
