Abstract: In this article, the aim was to compare and clarify the effect difference of three kinds of integrative water and fertilizer planting technology including furrow irrigation and water flush fertilizer (treatment I, CK), drip irrigation+ drip water flush fertilizer (treatmentⅡ) and drip irrigation+ drip-irrigation specific fertilizer (treatmentⅢ) on growth, yield and fruit quality of pepper in greenhouse were studied. By analyzing plant growth indexes, yield level, fruit quality and physiological indexes of pepper, the effects of three kinds of integrative water and fertilizer planting technology on the growth, yield and fruit quality of pepper in greenhouse were studied. The result showed that the plant height, stem diameter, bifurcation height, specific leaf area (SLA), leaf area ratio and leaf soluble sugar content and root activity of pepper under treatmentⅢwere significantly higher than those of treatment I (CK). Compare with CK, treatmentⅢincreased the yield by 40.1% and significantly improved the Vc, soluble protein content and dry matter content of fruit. The bifurcation height, SLA, leaf soluble sugar content, root activity and Vc, soluble protein and dry matter content of fruit in pepper under treatmentⅡalso were significantly higher than that of CK and yield increased by 28.64% . Among of treatmentⅡand treatmentⅢ, the plant height, stem diameter, root activity, yield and soluble protein content of fruit under treatmentⅢwere significantly higher those of treatmentⅡ. These results indicated that two integrative drip irrigation and fertilizer planting technology (treatmentⅡand treatmentⅢ) could promote plant growth, increase yield and fruit quality of pepper and the effects of drip-irrigation specific fertilizer on growth, yield and fruit quality of pepper in greenhouse were better than that of drip water flush fertilizer.
