为实现酸性土壤改良与土壤培肥同步、表层土与表下层土壤改良同步的目的,运用垂直深旋耕与无机、有机、生物等多物料综合协同改良酸性土壤,采用双因素裂区设计,试验设垂直深旋耕和传统耕作方式,以及石灰、石灰+绿肥、石灰+绿肥+酸性生物有机肥、石灰+绿肥+碱性生物有机肥等改土物料组合,研究了耕作方式和改土物料及其互作对植烟土壤理化特性及烤烟根系生长、农艺性状、经济性状、化学成分的影响。土壤理化特性受耕作方式和改土物料的影响,也受其互作的影响;垂直深旋耕可降低土壤容重,提高土壤孔隙度和土壤碱解氮、有效磷、速效钾含量,提高改土物料调酸效果;石灰与绿肥、生物有机肥配施更有利于改...

[Objective] The soil acidification, low organic matter and shallow ploughing have become one of the factors limiting the improvement of quality and efficiency of flue-cured tobacco. Deep vertical rotation tillage and application of ameliorative material mixing inorganic, organic and biological materials were conducted to improve the acidic soil, so as to realize the synchronization of acid soil improvement and soil fertilizer improvement as well as the synchronization of topsoil and subsurface soil improvement. [Method] Based on two-factor spli...
