摘要: 为了探索攀枝花地区不同酸碱植烟土壤上掺混控释肥适宜比例与效果,设置常规施肥(总养分投入N∶P2O5∶K2O =6.75∶6.35∶17.90,CK)、掺混控释肥1(不包膜∶控释30 d∶控释60 d∶控释90 d=4∶3∶2∶1,总养分投入量为N∶P2O5∶K2O=5.9∶5.5∶14.5,CF1)、掺混控释肥2(不包膜∶控释30 d∶控释60 d∶控释90 d=4∶4∶2∶0,总养分投入量为N∶P2O5∶K2O=5.9∶5.5∶14.5,CF2)和掺混控释肥3(不包膜∶控释30 d∶控释60 d∶控释90 d=4∶3∶2∶1,总养分投入量为N∶P2O5∶K2O=6.9∶6.5∶16.9,CF3)4 个处理,在不同pH土壤上研究其对烟株根系、产质量、化学成分等的影响。结果表明,CF3处理在土壤pH稍高的情况下烟草根系表现和产量更好,而CF2处理则在pH稍低的土壤上表现更好。在较高pH条件下,控释掺混肥可明显提高烟叶钾含量,并由此大幅度提高钾氯比,改善烟叶品质。

Abstract: To explore the suitable mixing ratio and effects of controlled-release blended fertilizers in tobacco planting soils with different pH values in the Panzhihua area, we set four treatments, which contained conventional fertilization (The total nutrient input was N∶P2O5∶K2O =6.75∶6.35∶17.90, CK), controlled-release blended fertilizer 1 (Non-coated treatment: controlled release treatment 30 d∶controlled release treatment 60 d∶controlled release treatment 90 d=4∶3∶2∶1,the total nutrient input was N∶P2O5∶K2O=5.9∶5.5∶14.5,CF1), controlled-release blended fertilizer 2 (The ratio of treatments was 4∶4∶2∶0, the total nutrient input was N∶P2O5∶K2O=5.9∶5.5∶14.5,CF2), and controlled-release blended fertilizer 3 (The ratio of treatments was 4∶3∶2∶1, the total nutrient input was N∶P2O5∶K2O=6.9∶6.5∶16.9,CF3), to study the effects on tobacco roots, leaf yield, leaf quality, and leaf chemical composition in soils with different pH. The results showed that the tobacco root performance and leaf yield were better under the CF3 treatment in the higher pH value soils; however, those were better under the CF2 treatment in the lower pH value soil. Under the higher pH value soils, blended controlled-release fertilizers could significantly increase the potassium content of tobacco leaves, thereby greatly increasing the potassium-chlorine ratio and improving the quality of tobacco leaves.
