摘要
为了提高烤烟品质和产量，利用获得国家专利的多元素液态肥料，对烤烟进行综合平衡施肥试验研究。结果表明，施用多元素液态肥后，烤烟主要化学组分在适中值或接近适中值，烟碱降低1．37％～9．13％；产量增加7％～26．7％，达到显著水平或极显著水平。烤烟的产质量都得到提高的主要原因是多元素液态肥含有60余种矿物营养元素，全面补偿了烤烟生长的各种需要。该成果的推广应用，将为促进烤烟种植的持续健康发展提供科技支撑。
The multi-mineral nutrition liquid fertilizer was used in the test of tobacco comprehensive balanced application to improve tobacco quality and yield. The results showed that the main chemical composition of tobacco after applying the multi-mineral nutrition liquid fertilizer was in the moderate value or near moderate value, the nicotine content reduces from 1.37% to 9. 13% and the yield increased by from 7% to 26. 7% compared with CK （without applying the multi-mineral nutrition fertilizer）. The main reason of improving tobacco yield and quality after applying the multi-mineral nutrition fertilizer with more than 60 mineral nutrition elements can effectively compensate and support the needs of tobacco growth. The multimineral nutrition fertilizer should be used in tobacco production to support the sustainable development in Guizhou.
