菇渣有机肥对烟田土壤养分含量及烟草品质的影响

Effects of Mushroom Dregs on Soil Nutrients Content and Tobacco Quality

通过田间试验,研究了菇渣有机肥不同施用量对土壤养分含量、烟株生长状况、烟叶经济性状及常规化学成分的影响。结果表明,施用菇渣有机肥提高了土壤有机质、碱解氮、速效磷、速效钾的含量;与对照相比,烟株农艺性状中的株高、有效叶片数、茎围和节距均占优势;烟叶产量和产值等经济性状也有明显提高;烟叶常规化学成分更加协调,趋于优质烟叶。其中,以200 kg/667m2的施用量效果最好。

Field experiments were conducted to study the content, tobacco growth, tobacco economic characters and effects of different application rates of mushroom dregs on soil nutrients conventional chemical components. The results showed that by applying mushroom dregs, soil organic matter, alkaline nitrogen, available phosphorus and available potassium contents increased, tobacco agronomical characteristics of plant height, effective leaf number, stem circumference and pitch were superior than those of the control, economic characteristics of yield and output value of tobacco leaves were also improved obviously, and conventional chemical components of tobacco leaves were more coordinated and tended to be high quality tobacco leaves. When the application rate of mushroom dregs was 200 kg/667m2, the effect was the best.
