摘要
为研究烟草新型土壤调理剂在植烟沙泥田的改良效果,与传统产品进行比较,了解其对烟草的促进作用以及沙泥田土壤理化性质的影响。通过盆栽试验,比较了烟草新型土壤调理剂和其他3种产品在植烟沙泥田土壤的改良效果。结果表明:(1)新型土壤调理剂促进烟草的生长发育,与对照处理相比,新型土壤调理剂处理的有效叶片数、茎秆鲜重显著增加10.71%、54.3%;同时,单株生物量显著高于对照处理、健地调理剂处理、烟叶宝调理剂处理,达到1604.18 g。(2)新型土壤调理剂处理显著改变了沙泥田土壤理化性状,在移栽前显著提高土壤pH至7.36,土壤速效氮、磷养分含量显著提高22.5%、48.8%。(3)新型土壤调理剂处理显著提高了烟叶的还原糖、钾含量。综上所述,在盆栽试验条件下,以新型土壤调理剂对沙泥田的土壤改良和促进烟草生长效果最好。
A pot experiment of a newly developed conditioner was conducted to investigate the impact on soil physicochemical properties of sandy soil,the promotion of tobacco growth,and tobacco quality and to compare the soil improvement effects of novel tobacco soil conditioner and other three products in tobacco-sandy mud fields.The novel soil conditioner promoted the growth and development of tobacco.Compared with the control treatment,the effective leaf number and stem fresh weight of the novel soil conditioner treatment increased significantly by 10.71%and 54.3%.The amount of 1604.18 g was significantly higher than that of the control treatments including Jiandi conditioning agent treatment,and Yanyebao conditioning agent treatment.The application of the novel soil conditioner treatment significantly improved the soil physicochemical properties of the sandy soil.Before transplanting,the soil pH was significantly increased to 7.36,and available nitrogen and phosphorus contents of the soil were significantly increased by 22.5%and 48.8%respectively.The novel soil conditioner treatment significantly increased the reducing sugar and potassium content of tobacco leaves.In conclusion,under the conditions of the pot experiment,the novel soil conditioner had a better effect on improving the sandy soil and promoting the growth of tobacco.
