炭基有机肥对植烟红壤肥力特征和烤烟生长的影响
Effects of Carbon-based Organic Fertilizer on Fertility Characteristics of Red Soil and Growth of Flue-cured Tobacco
摘要
Abstract
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.关键词
