摘要
通过田间小区试验,研究赣北土壤中有效磷含量高(48.32mg/kg)的田块上烤烟适宜的磷肥用量。试验结果表明,在该类型田块上,不同的磷肥用量对烤烟的生长发育及产质量有不同程度的影响,适当降低磷肥施用量更有利于烤烟生长发育及产质量性状的形成。本试验条件下,以每公顷施P2O560-90kg效果最好。
A field trial was conducted in the soil with high available phosphate content (48.32mg/kg) to study the appropriate amount of phosphorus for flue-cured tobacco in North Jiangxi Province. The results showed that different phosphorus amounts had different effects on growth, yields and quality of flue-cured tobacco. Reducing phosphorus amount properly could improve the growth, yields and quality of flue-cured tobacco. Under the condition of this experiment, the best phosphorus level is applying P2O5 60-90 kg per hectare.
