Abstract: Taking processed pepper ‘Yingchaohong No.4’ as materials, the responses of dry matter accumulation and distribution of processed pepper to planting methods were studied by using split zone design method, in order to provide reference for high-yield and high-efficiency cultivation technology of processed pepper.The results showed that the dry matter accumulation of the stems and leaves of processed pepper under different planting patterns（three kinds of densities and three kinds of row spacing treatments） displayed a trend of increasing first and then decreasing, and the peak value was in the fruiting stage, while the dry matter accumulation of fruits was gradually increasing with the advancement of the growth period.Compared with the row spacing 60+60 treatment, the wide-narrow planting（80+40,70+50） was conducive to promoting the accumulation and distribution of dry matter in various organs, increasing the contribution rate of stems and leaves to fruits.And when the density was higher, its contribution to the fruit was more obvious.When the density was 82 500 plants per hectare, and the row spacing was 80+40,the plant population was distributed reasonably, the dry matter accumulation of each organ was the most, the dry matter transshipment, transfer rate and the contribution to the fruit of stem and leaves was the highest, and the potential for increasing yield was the best.It was the best planting patterns of processed pepper.
