摘要
为探索适宜烤烟生长的前茬作物,完善烤烟的种植制度,以烤烟连作为对照(CK),研究了玉米(处理T_(1))、豆类/蔬菜(处理T_(2))和马铃薯(处理T_(3))3种前茬作物对烤烟成熟期农艺性状、根系发育、生物量和土壤养分含量的影响。结果表明,所有农艺性状指标中数值较高的均为处理T_(2),各处理根深度和水平根宽度表现为处理T_(2)>处理T_(3)>处理T_(1)>CK,根、茎、叶干物质重表现为处理T_(2)>处理T_(3)>处理T_(1)>CK;土壤pH值、有机质含量、碱解氮含量均表现为处理T_(2)>处理T_(1)>处理T_(3)>CK。综上,适宜烤烟生长的前茬作物为豆类/蔬菜,其次为马铃薯。
In order to explore the pre-crops suitable for flue-cured tobacco growth and improve the planting system of flue-cured tobacco,the effects of three pre-crops of corn(treatment T_(1)),beans/vegetables(treatment T_(2))and potatoes(treatment T_(3))on agronomic traits,root development,biomass and soil nutrient content at the ripening stage of flue-cured tobacco were studied by using continuous cropping of flue-cured tobacco as control(CK).The results showed that the higher value among all agronomic traits was found in the treatment T_(2).The root depth and horizontal root width in various treatments represented as treatment T_(2)>treatment T_(3)>treatment T_(1)>CK,the dry matter weight of roots,stems,and leaves represented as treatment T_(2)>treatment T_(3)>treatment T_(1)>CK,and the pH value,organic matter content,and alkaline nitrogen content in soil represented as treatment T_(2)>treatment T_(1)>treatment T_(3)>CK.In summary,the pre-crops suitable for flue-cured tobacco growth were beans/vegetables,followed by potatoes.
