为了找出影响菜椒产量的主要因素及各因素的最佳取值水平，帮助菜农更好的科学安排生产，本文通过正交试验设计方法以甘肃省张掖市甘州区长安乡郭家堡村2008年菜椒的产量数据为例对影响菜椒产量的因素做出了分析，并得出了各因素的最佳取值水平为施肥量140kg／亩，苗期为60天，栽培密度为4250株／亩的重要结论。
英文摘要：
In order to find the main influence factors of the green pepper production and help vegetable growers design production more scientific, in this paper, orthogonal experiment design method is employed to make the research of the influence factors for the green pepper output based on the 2008 experiment data of Guojiapu village located in Ganzhou Prefecture of Zhangye city, at the foot of the Qilian Mountains of Gansu Province. Finally, we get the best value of the three influence factors for the fertilizer level is 140 kg/mu, the seedling stage is 60 days, planting density is 4250 zhu/mu.
