摘要
为探讨朝天椒的最佳栽培密度,以朝天椒品种福建辣椒王为试验材料,设置6个栽培密度处理,研究了不同栽培密度对朝天椒植株生长和产量的影响。结果表明:栽培密度对朝天椒的始花期、始收期、终收期等生育进程无影响;栽培密度对朝天椒植物学性状有较大影响,随着栽培密度增大,朝天椒株高呈逐渐升高趋势,株幅和分枝数呈逐渐下降趋势;栽培密度对朝天椒经济性状有影响,随着栽培密度的增大,朝天椒单株产量和单株结果数显著降低,其平均单果重呈逐渐减小的趋势;中低栽培密度时朝天椒产量随栽培密度的增大呈逐渐升高趋势,当栽培密度为3.705 0万株·hm^-2时,朝天椒产量达到最高(每667 m^2为1 236.7 kg),但当栽培密度为4.764 0万株·hm^-2,产量反而显著下降。
In order to study the optimum cultivation density of pod pepper,the effects of different cultivation densities on the growth and yield of pod pepper were studied by using Fujian Pepper King as the experimental material and setting 6 cultivation densities.The results showed that the cultivation density had no effect on the growth process of pod pepper,such as the early flowering season,the initial harvesting period and the final harvesting period.The cultivation density had a great influence on the botanical characteristics of pod pepper.With the increase of cultivation density,the plant height of pod pepper showed a trend of gradual increase,while the plant width and branching number showed a trend of gradual decrease.The cultivation density had an effect on the economic characters of pod pepper.With the increase of the cultivation density,the yield and fruit number per plant significantly decreased,and the average weight of single fruit showed a trend of gradual decrease.The yield of pod pepper showed a trend of gradual increase with the increase of cultivation density when the cultivation density was low and medium.When the cultivation density was 37 050 plant per hm^2,the yield of pod pepper reached the highest(1 236.7 kg per 667 m^2).However,when the planting density was 47 640 plant per hm^2,the yield decreased significantly.
