摘要
通过大田试验,将4种不同培肥方法(玉米秆异地还土、配施有机肥、配施生物炭和冬季种植箭舌豌豆)应用于整理后的植烟旱地中,研究了不同培肥方法对土壤物理性状、土壤养分、烤烟产量和烟叶品质等影响。结果表明,4种培肥方法对土壤物理性状影响并不明显,但能一定程度地提高土壤有机质和土壤各养分含量,能一定程度地提高烟叶产量,能增加总糖和还原糖的含量,提高钾含量和降低氯和粗蛋白的含量,其中又以配施有机肥的处理效果相对较好。因此,在整理后的植烟旱地土壤中,配施有机肥值得推广应用。
A field experiment was carried out to study the effects of different fertilization methods applied in tobacco planting upland in land consolidation area on soil physical properties, soil nutrients, as well as the yield and quality of tobacco leaves. The experiment included 4 fertilization methods： corn stalk returning, combined application of organic fertilizer, combined application of biological carbon, and planting Vicia Satativa L.in winter. The results showed that the effects of 4 methods on soil physical characteristics were not obvious, but the 4 methods could improve the content of soil organic matter and nutrients to a certain extent as well as the yield of tobacco leaves, increase the content of total sugar and reducing sugar, and increase potassium content and decrease the content of chlorine and crude protein; the effect of combined application of organic fertilizer was relatively better. Therefore, the application of organic fertilizer in tobacco planting upland in land consolidation area is worthy of popularization and application.
