| 摘 要： | 研究不同质地贵州黄壤主要养分在烤烟生长发育周期内的动态变化及其对烟叶产量、品质的影响.将威宁粉壤土、开阳壤粘土同置于开阳气候下,采用统一栽培措施种植烤烟.研究发现,与高等肥力的壤粘土比较,中等肥力的粉壤土矿化率更高,无机氮、有效磷含量更高,利于保存施入的铵态氮,烟叶氮素、钾素浓度更大,烟叶钾氯比更大,烟叶产量更高.而高...

| Abstract: | Flue-cured tobacco was planted in silty loam collected from Weining and loam clay collected from Kaiyang under the same cultivated pattern in Kaiyang county to study the effect of dynamic changes of main nutrients in different texture yellow soils from Guizhou on the yield and qualities of tobacco leaves in the growth and development cycle.The results showed that silty loam in the middle fertility level mineralized more,as the contents of inorganic nitrogen and available phosphorus were higher,which was ben... |
