Dry Matter Accumulation and Nitrogen Absorption Characteristics of Processed Pepper under Different Nitrogen Levels

In order to promote the rational use of nitrogen fertilizer, dry matter accumulation, absorption processed pepper were studied by substrate culture and quantitative irrigation nutrient solution under 6 different levels (60%, 80%, 90%, 100%, 120% 140% normal N application). It showed that, with increase application, weight leaf, fruit, stem, root, plant increasing; The content each part run up maximum at 80%~100% level; There was no significant difference between fruit, as well as nitrogen content accumulation these parts at level. Correlation analysis that highest correlation plant, but had little in part. addition, slight can reflect its nutritional status, while amount its accumulation. This study will provide theoretical reference for application fertilizer in processed pepper.
