| 摘 要： | 通过大田试验研究了揭膜后不同秸秆覆盖量(3000kg/hm2,6000kg/hm2,9000kg/hm2)对烟田土壤的物理、化学、生物特性以及烟叶品质的影响。结果表明:揭膜后覆盖秸秆可以降低土壤容重和pH值,调节地温,提高土壤有机质和水分含量,增加土壤微生物数量,提高烟叶钾含量。与不覆盖秸秆比较,覆盖秸秆处理的土壤容重降低0.027~0.075g/cm3,土壤pH值降低0.18~0.44,土壤有机质含量增加0.3~1.0g/kg,烟叶钾含量增加0.10%~0.29%。在3个覆盖处理中,以6000kg/hm2覆盖量处理对改善烟田土壤性状和烟叶质量的效果最好。

| Abstract: | The field experiment were carried out to study the effect of different straw mulching rates(3000kg/ha,6000kg/ha and 9000kg/ha)on soil physical,chemical and biological properties of tobacco field and quality of tobacco leaves after film uncovering.The results indicated that the application of straw mulching after film uncovering decreased soil bulk density and soil pH,adjusted soil temperature,increased organic matter,water and microbial biomass in soil and content of potassium in tobacco leaves.Compared to ck (no straw mulching),straw mulching treatments decreased soil bulk density by 0.027-0.075g/cm3,soil pH by 0.18-0.44,and increased soil organic matter content by 0.3-1.0g/kg,potassium content of leaf tobacco by 0.10%-0.29%.Among the three treatments of straw mulching rate,the 6000kg/ha treatment showed the best effect on improving soil properties of tobacco field and quality of tobacco leaves. |
