不同有机肥与无机肥配施对烤烟生长发育及产质量的影响

Effects of Application of Different Types of Organic Fertilizer Combined with Inorganic Fertilizer on the Growth and Quality of the Flue-cured Tobacco

为改善植烟土壤环境,提高烟叶产质量,以云烟121为试验材料,通过田间试验,研究不同生物有机肥与无机肥配施对烤烟生长发育及产质量的影响。结果表明,配施有机肥可促进烟株早期早发快长及后期成熟落黄,有效提高烟株茎围和最大叶面积,增强烟株抗病性,改善烟叶化学成分协调性,增加中上等烟比例。各处理以牛粪菌渣有机肥在洛南烟叶生产中使用效果最优。

In order to improve the soil ecological environment,the yield and quality of tobacco,field experiments were conducted with Yunyan 121 as the experimental material to study the effects of different organic fertilizers combined inorganic fertilizer on the growth and development,yield and quality of flue-cured tobacco.The results showed that the organic fertilizers could promote the early growth and later maturity of tobacco leaves,improve stem circumference and the maximum leaf area of flue-cured,enhance the disease resistance,improve flue-cured tobacco chemical composition,increase the first and second class tobacco proportion.Among all the treatments,the organic fertilizer compriesed of cow dung fungus residue performed best.
