Effects of Carbon-based Organic Fertilizer on Fertility Characteristics of Red Soil and Growth of Flue-cured Tobacco
本研究旨在探究炭基有机肥对植烟红壤肥力特征以及烤烟生长的影响,从而明确炭基有机肥在植烟红壤改良培肥与烤烟生产中的应用成效.以四川攀西地区典型的植烟红壤作为研究对象,借助田间试验,设置了5个处理,分别为对照(CK,T1)、单施生物炭(T2)、单施腐熟牛粪(T3)、由50%腐熟牛粪与50%生物炭复配而成的炭基有机肥(T4)、由70%腐熟牛粪与30%生物炭复配而成的炭基有机肥(T5),并测定了各处理对土壤肥力特征和烤烟生长性状的影响.研究结果显示,炭基有机肥能够更有效地协调烤烟全生育期的土壤养分平衡,为烤烟的生长发育提供更为优质的养分支持.在烤烟成熟期,炭基有机肥处理相较于T2和T3处理,可使土壤pH提升0.16～0.22个单位,有机质含量提高28.84%～33.21%,有效磷含量增加52.84%～62.19%.在两个炭基有机肥处理之间,T5处理对土壤碱解氮的提升效果更为显著(P＜0.05),而T4处理对速效钾含量的提升作用更明显(P＜0.05).炭基有机肥有利于推动烤烟的生长.在烤烟成熟期,其株高相较于T2、T3处理增加4.13%～16.67%,茎围增大5.45%～15.79%.冗余分析结果表明,炭基有机肥主要通过影响土壤pH和有效磷来作用于烤烟生长.综上所述,炭基有机肥能够调节植烟红壤的pH,增加土壤中有机质和有效养分的含量,平衡烤烟的养分需求,进而促进烤烟的生长.
The study aims to explore the effects of carbon-based organic fertilizer on the fertility characteristics of red soil and flue-cured tobacco growth,and to determine the application effect of carbon-based organic fertilizer in the improvement and cultivation of red soil for tobacco growing and flue-cured tobacco production.Taking the typical tobacco-growing red soil in Panxi area of Sichuan Province as the research object,field experiments were conducted.The effects of treatments,including control(CK,T1),biochar(T2),cow manure(T3),cow manure 50%combined with biochar 50%(T4)and cow manure 70%combined with biochar 30%(T5),on soil fertility characteristics and growth characteristics of flue-cured tobacco were determined.The results showed that carbon-based organic fertilizer could better coordinate the soil nutrient balance during the whole growth period of flue-cured tobacco and provide better nutrient support for its growth and development.In the mature stage of flue-cured tobacco,the soil pH value,organic matter and available phosphorus were increased by 0.16-0.22,28.84%-33.21%and 52.84%-62.19%respectively compared with the T2 and T3 treatments.The T5 treatment significantly increased soil alkali-hydrolyzed nitrogen(P＜0.05),while the T4 treatment significantly increased soil available potassium content(P＜0.05).Carbon-based organic fertilizer could promote the growth of flue-cured tobacco,and the plant height increased by 4.13%-16.67%and stem circumference increased by 5.45%-15.79%compared with the T2 and T3 treatments.The results of redundancy analysis showed that the growth of flue-cured tobacco was mainly affected by pH and available phosphorus.In conclusion,carbon-based organic fertilizer can adjust the pH of red soil,increase the content of organic matter and available nutrients,balance the nutrient demand of flue-cured tobacco,and promote the growth of flue-cured tobacco.
