【摘要】 为生物醋液对植烟土壤的改良及在烤烟生产上的应用提供依据,采用盆栽试验,研究不同原料来源生物醋液对烤烟农艺性状,植烟土壤pH、容重、有机碳含量及酶活性和微生物含量等的影响。结果表明:施用生物醋液能够降低植烟土壤容重,提高土壤酶活性及增加土壤微生物含量,促进烤烟生长。其中,桃壳木醋液改良土壤的效果及对烤烟生长的促进作用较其他生物醋液明显,土壤容重最小,为1.23g/cm3,显著低于其他处理;有机碳含量最高,为11.56g/kg,是对照(清水)的1.17倍;植烟土壤脱氢酶、磷酸酶、蔗糖酶及脲酶活性分别较对照高26.4%、31.7%、62.3%和53.9%;微生物总量为对照的2.06倍;最大叶面积较对照提高33.9%。更多还原

【Abstract】 In order to provide references for the application of biological vinegar in flue-cured tobacco cultivation,apot experiment was conducted to study the effects of different raw material sources of biological vinegar on agronomic traits,soil pH,bulk density,organic carbon content,enzymes activity and microbial content of flue-cured tobacco.Results:The application of biological vinegar could promote the growth of flue-cured tobacco,reduce the bulk density,increase soil enzyme activity,and increase soil microbial content of tobacco planting soil.Among them,peach-shell wood vinegar performed better than other biological vinegars in improving soil quality and promoting flue-cured tobacco growth.The soil bulk density was merely 1.23 g/cm3,significantly lower than all the other treatments;Organic carbon content was the highest,11.56 g/kg,1.17 times of the control;Soil dehydrogenase,phosphatase,sucrase,and urease activities were increased by 26.4%,31.7%,62.3%,and 53.9%,respectively in comparison with the control;the total amount of microorganisms was 2.06 times that of the control.The maximum leaf area was 33.9% higher than the control.更多还原
