| 摘 要： | 研究表明,土壤温度对藏东南地区烤烟产、质量具有关键影响.烟苗假植、适时垄栽、全程覆膜及非灌溉条件下中耕调控,增温保墒效果显著,烟株生长发育正常,烤烟土壤温度及水分生态适应性基本适宜.植烟土壤土质轻粗、土体疏松,有利于烟根烟碱合成和吸钾量的提高.pH6.2～7.3范围内,烤烟产、质量不受pH单一因子的影响.植烟土壤有效氮、磷(P2O57.1～12.2mg/kg)、钾严重失衡(14.6∶1∶13.6),充分发挥磷肥促进早发、加强生长、提前成熟的作用,对高海拔的藏东南地区烤烟优质适产具有特殊意义.

| Abstract: | The study indicated that the soil temperature had crucial effect on the yield and quality of tobacco. The tobacco seedlings heeled in, ridge cultured in the right season, plastic film covered the ground during the whole growing period and intertilled under non-irrigation had a marked results on the adding the temperature and protecting the soil moisture content. The ecological adaptability of tobacco to soil temperature and moisture condition was fundamental suitable in the tobacco g... |
