定植方式和穴距对露地辣椒农艺性状和产量的影响

Effect of planting method and plant spacing on agronomic traits and yield of pepper for outdoors

采用两因素随机区组试验设计,研究北方赤峰地区越夏茬露地辣椒不同定植方式及穴距对辣椒农艺性状及产量的影响。结果显示:两种定植方式对辣椒产量影响不显著;单株定植与双株定植相比,株高显著下降,株幅有所增加;单果质量和单株商品果数均显著提高。结论为单株定植更适于赤峰越夏茬露地辣椒生产,穴距以24 cm为宜。

The experiments were performed with two factors of randomized complete block design （RCBD） to study the effect of different planting method and plant spacing on agronomic traits and yield of pepper for outdoor in summer in Chifeng of Inner Mongolia. Two planting methods （single plant cultivation and double plant cultivation） had the same yield of pepper. Single planting cultivation of pepper had significant increase in plant spread, average fresh fruit weight, average fruit yield per plant and plant height. The results indicated that single planting cultivation of pepper for outdoors in summer with plant spacing 24 cm is the preferred planting method for pepper production in the Chifeng of Inner Mongolia.
