不同耕作方式对植烟土壤及烤烟品质的影响

Effects of Different Cultivation Methods on Tobacco Planting Soil and Tobacco Quality

本试验以云烟87为材料,设置旋耕、松地、翻地3种耕作方式,研究不同耕作方式对植烟土壤及烤烟品质的影响。结果表明:在烟草整个生育期内,旋耕处理对植烟土壤速效钾含量有较好的影响,松地处理对植烟土壤碱解氮含量、有效磷含量以及烟草大田前期(移栽后30~60 d)的土壤有机质含量有较好的影响;翻地处理对烟草大田后期(移栽后90~120 d)的土壤有机质含量有较好的影响;松地和翻地处理相对于旋耕处理可以提高烟叶的总糖和还原糖含量、降低烟碱含量。总体来说,相较于旋耕,松地和翻地对植烟土壤和烤烟品质的影响更好。

This experiment used Yunyan 87 as the material and set up three cultivation methods(rotary tillage,loosening and soil turning)to study the effects of different cultivation methods on tobacco planting soil and tobacco quality.The results showed that during the entire growth period of tobacco,rotary tillage treatment had a good effect on the available potassium content in tobacco planting soil,while loosening treatment had a good effect on the alkaline hydrolyzable nitrogen content,available phosphorus content,and soil organic matter content in the early stage of tobacco field(30-60 days after transplantation);the soil turning treatment had a good effect on the soil organic matter content in the late stage of tobacco field(90-120 days after transplantation);loosening and soil turning treatments could increase the contents of total sugar and reducing sugar of tobacco leaves and reduce nicotine content compared with rotary tillage treatment.Overall,compared with rotary tillage,loosening and soil turning have a better effect on tobacco planting soil and tobacco quality.
