摘要
以云烟87为材料,采用双因素试验,研究了2种追肥模式(传统追肥模式、水溶性追肥模式)配施促根剂(地康食安1号、诱抗特、普多收魔力根)在不同移栽天数后对烤烟干物质和氮、磷、钾养分积累及肥料吸收效率、肥料生产效益的影响。结果表明:传统追肥模式不利于烟叶后期脱氮,水溶性追肥模式可促进烟叶落黄成熟;水溶性追肥模式和促根剂及其互作均有利于烤烟干物质积累,可改善烟株氮、磷、钾积累和分配状况,提高烤烟的养分吸收效率和生产效益;追肥模式、促根剂及其互作对干物质积累的贡献率分别为37.64%、41.35%、21.01%,对氮积累的贡献率分别为34.14%、33.78%、32.08%,对磷积累的贡献率分别为34.41%、33.47%、32.12%,对钾积累的贡献率分别为32.12%、36.56%、25.16%。在湖南稻作烟区,采用水溶性追肥配施地康食安1号、诱抗特可显著促进烤烟生长前期干物质积累,显著增加烤烟氮、磷积累量,有效提升肥料吸收效率和生产效益。
Using flue-cured tobacco cultivar Yunyan87 as the material,the effects of two topdressing modes(traditional topdressing and water-soluble topdressing)combined with root promoting agents(Dikangshian1,Youkangte and Puduoshoumoligen)on the accumulation of dry matter,nitrogen,phosphorus and potassium,and on fertilizer absorption efficiency and fertilizer production efficiency of flue-cured tobacco at different days after transplanting were studied.The results showed that the traditional topdressing mode was not conducive to the nitrogen removal of tobacco leaves,while the water-soluble topdressing mode could promote the yellowing and ripening of tobacco leaves.Water-soluble topdressing mode and root promoting agents and their interactions were beneficial to dry matter accumulation,and could improve nitrogen,phosphorus and potassium accumulation and distribution,and increase nutrient absorption efficiency and production benefit of flue-cured tobacco.The contribution rates of topdressing mode,root promoter and their interaction to dry matter accumulation were 37.64%,41.35% and 21.01%,respectively;the contribution rates of topdressing mode,root promoter and their interaction to nitrogen accumulation were 34.14%,33.78%and 32.08%,respectively;the contribution rates of topdressing mode,root promoter and their interaction to phosphorus accumulation were 34.41%,33.47% and 32.12%,respectively;and the contribution rates of topdressing mode,root promoter and their interaction to potassium accumulation were 32.12%,36.56% and 25.16%,respectively.In Hunan tobacco-rice rotation area,the application of water-soluble topdressing combined with the application of Dikangshian 1 and Youkangte can significantly promote the dry matter accumulation of flue-cured tobacco in early growth stage,significantly increase the accumulation of nitrogen and phosphorus,and effectively improve the fertilizer absorption efficiency and production efficiency.
