摘要: 为探讨烟草废弃物生产有机肥对植烟土壤养分含量的影响,通过对烟草废弃物生产有机肥、烟草专用化学肥对植烟土壤影响的对比,以及不同有机肥配比量对改善植烟土壤的作用对比,分别测定了其对有机质含量、碱解氮、速效磷、速效钾含量以及全氮、全磷、全钾含量的影响。结果显示土壤碱解氮、速效磷、速效钾的含量与有机肥施用量呈正比例关系,同时有机肥的施用能增加土壤中有机质、全氮、全磷、全钾的含量,且当有机肥所占比例为50%时,植烟土壤中养分含量增加显著且符合优质烟叶生产的土壤条件,效果最为理想。实验表明烟草废弃物生产有机肥能有效改善土壤理化性质,增加土壤肥力,改善烟叶品质。同时在一定程度上可减少化肥的施用,进而保护土壤环境,实现烟草废弃物的循环利用。

Abstract: The study aims to investigate the effects of tobacco waste as organic fertilizer on nutrient content of tobacco-planting soil. By comparing the influence of the organic fertilizer produced by tobacco waste and that of the special tobacco chemical fertilizer on tobacco-planting soil and the effect of different amounts of organic fertilizer on tobacco-planting soil improvement, the authors measured the impact of the organic fertilizer produced by tobacco waste on the content of organic matter, soil alkali-hydrolyzable nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus and total potassium. The result showed that the content of soil alkali-hydrolyzable nitrogen, available phosphorus and available potassium presented a direct proportion relationship with the organic fertilizer content. In the meantime, organic fertilizer could increase the content of soil organic matter, total nitrogen, total phosphorus and total potassium. When the organic fertilizer proportion was 50%, nutrient content of tobacco-planting soil increased significantly and accorded with the soil condition for producing high quality tobacco leaves. The experiment proved that the organic fertilizer produced by tobacco waste could improve soil physical and chemical properties, increase soil fertility, improve tobacco quality. It could also reduce chemical fertilizer use simultaneously, thus to protect the soil environment and realize the recycling of waste tobacco.
