摘要:
为探讨不同土壤改良剂对植烟土壤和烤烟品质的改良效果,设置不施用肥料(CK)和分别施用聚丙烯酰胺(T1)、生物炭(T2)和高碳基有机肥(T3)共4个处理,采用大田试验研究了不同处理对烤烟农艺性状、土壤理化性质、烟叶内在品质和经济性状的影响。结果表明,T3处理烤烟具有更高的生长指标,尤其在最大叶面积上显著高于T1和T2处理,增幅分别为17.06%和14.48%;T3处理土壤电导率显著增高,较T1和T2处理分别提高了83.38%和85.82%;T2处理土壤有机碳含量最高,相比于T1和T3处理,增幅分别为113.60%和53.45%;相比于CK,T3处理土壤细菌数量显著提高了10.44%,真菌数量显著降低17.51%;与CK相比,T2和T3处理显著提高了烟叶总糖、还原糖、钾含量和糖碱比、钾氯比,烟叶氯含量不同程度降低。T3处理下烟叶总糖、还原糖和钾含量较T1处理显著提高了8.22%、12.67%和5.26%;在产量、产值指标上,T3处理较T1和T2处理分别显著提高了14.29%和7.01%、20.81%和12.62%。说明施用土壤改良剂能不同程度提高土壤养分和烟叶内在品质,以高碳基有机肥处理效果最佳。
