不同碳氮比有机肥对烤烟生长和土壤肥力的影响

Effects of Organic Fertilizers with Different C/N Ratios on Tobacco Growth and Soil Fertility

通过田间试验研究了不同碳氮比有机肥对烤烟生长发育、烟叶品质和土壤养分的影响,结果表明,参试的有机肥都在不同程度上促进了烤烟的发育、养分吸收、烟叶质量和产值,其中以C/N比最高的M4效果最好,其次是C/N比较高的M2和M3,这三种有机肥对烤烟生长、烟叶品质的作用都优于C/N比较低的饼肥.

A field experiment was conducted in Chongqing to study the effect of organic fertilizers with different C/N ratios on the growth and quality of tobacco and on soil fertility.Laboratory analysis showed that the application of different organic fertilizers all promoted the growth,nutrient uptake,quality and output of tobacco in different degrees.The treatment of M4,which was high in C/N,had the best result,followed by treatments M2 and M3,which were relative high in C/N.These three organic fertilizers had better effects on tobacco than cake fertilizer,which was relatively low in C/N.
