生物有机肥对植烟土壤肥力及烤烟干物质积累的影响

Effect of Bio-organic Fertilizer on Soil Fertility and the Dry Matter Accumulation of Flue-cured Tobacco

通过田间试验 ,研究了生物有机肥和化肥配比对植烟土壤肥力及烤烟干物质积累的影响。结果表明 ,在施用化肥的基础上配施生物有机肥 ,可以改善植烟土壤的肥力状况 ,使植烟土壤有机质含量增加 ,提高酸性土壤的 pH值 ;碱解氮、速效磷、速效钾含量与烟株的生长发育趋于协调 ;促进了烤烟根、茎、叶干物质积累。

The field experiments were carried out to study the effect of combining application of bio organic fertilizer and chemical fertilizer on the soil fertility and the dry matter accumulation of flue cured tobacco. The results showed that adding bio organic fertilizer at the base of using chemical fertilizer can improve the soil fertility, which can increase the content of soil organic and the pH of acid soil. Using bio organic fertilizer made the content of soil rapidly available N,P and K in harmony with the growing of tobacco. It also enhanced the dry matter accumulation of root, stem and leaver of flue cured tobacco.
