Effect Of Flue-cured Tobacco Fertilization Technology On The Yield And Quality In Puer

A filed experiment was conducted to study the effects of different fertilizer and methods about nitrogen, phosphorus and potassium; interim regulation of fertilizer technology; mixed organic manure and inorganic fertilizer on tobacco quality. The main results show that:1 The effects of different fertilizer and methods about nitrogen, phosphorus and potassium on the leaf quality.Pure N 10kg/acre, P2O5 6kg/acre, K2O 8kg/acre exhibits better result in Simao, Yunxian and Zhenyuan, Mengda pilot sites; while in Mojiang, Yutang N 6kg/acre, P2O5 10kg/acre, K2O 14kg/acre is much better.2 Effect of different fertilization methods on the quality of tobaccoIn different fertilization methods trails,70% base fertilizer with 30% top dressing has little differentiation compare with 60% basal dressing with 40% top dressing.60% base fertilizer with 5%+5%+5%+5%+20% top dressing is best. Applying fertilizer with water can promote root and germination after flue-cured tobacco transplanting.3 The research of interim regulation of fertilizer technologyComprehensive analysis of the growing period agronomic trails,60% basal dressing, 30% top dressing,10% regulation fertilizer is great in topping period.50% basal dressing, 30% top dressing,20% regulation fertilizer in topping period and 60% basal dressing,30% top dressing,10% regulation fertilizer are normal.50% basal dressing,30% top dressing, 20% regulation fertilizer in initial picking is worse.4 Mixed organic manure and inorganic fertilizer application on leaf qualityTreatment C (composting manure 800kg/acre + fertilizer nitrogen 6.5kg/acre) is best; treatment E (fertilizer nitrogen 7kg/acre) is worst.
