摘　　要：为探究定植密度对花椒产量的影响,设置定植密度分别为600、800、1000、1200株/hm^(2)等4种情况进行花椒种植的田间试验,考察定植密度对花椒植株生长参数和农艺性状的影响,进而分析定植密度对产量的综合影响。结果显示,适宜的定植密度不仅有利于花椒植株的健康生长,还能显著提高其农艺性状和产量,但随着定植密度的增加,花椒植株的株高、冠幅及发枝量呈现出下降趋势,而产量则呈现先增后降的趋势,在1000株/hm^(2)的定植密度下,产量为1844.25 kg/hm^(2),较600株/hm^(2)的定植密度提高了55.15%。因此,生产中可结合实际情况选择1000株/hm^(2)的定植密度较为适宜。In order to investigate the effect of planting density on the yield of Zanthoxylum bungeanum,the planting density was 600800,1000,1200 plants/hm^(2) in a field experiment,and the effects of planting density on the growth parameters and agronomic traits of Zanthoxylum bungeanum were investigated.Then the comprehensive effect of planting density on yield was analyzed.The results showed that moderate planting density was not only beneficial to the healthy growth of Zanthoxylum bungeanum plants,but also significantly improved agronomic traits and yield.However,with the increase of planting density,the plant height,crown width and number of branches of Zanthoxylum bungeanum plants showed a downward trend,while the yield showed a trend of first increasing and then decreasing.The yield was 1844.25 kg/hm^(2),which was 55.15%higher than that of 600 plants/hm^(2).Therefore,the planting density of 1000 plants/hm^(2) could be selected according to the actual situation in production.
