Research on Balanced Fertilization Technology for Dryland Flue-cured Tobacco
Objective:To study the balanced fertilization technology for dryland tobacco.Method:Select a moderately fertile experimental site for field experiments,design three different fertilizer ratios for fertilization schemes 1,2,and 3,and compare the soil organic carbon content,tobacco growth and development status,and tobacco yield under different fertilization ratios.Result:In the study of soil organic carbon content,the balanced fertilization scheme was applied,and the soil organic carbon content was higher than other treatments,at 10.86 g/kg,with significant differences.The soil quality of tobacco was better;In the study of tobacco growth and development,under balanced fertilization treatment,the highest growth in-dicators such as plant height,ground diameter,maximum leaf area,number of leaves,biomass,leaf color,evenness,luster,and growth vigor were observed,and the growth characteristics of tobacco were superior;In the study of tobacco yield,applying the balanced fertilization treatment scheme designed in this article,the net profit of tobacco output is higher,reaching 49250 yuan/hm2,and the economic characteristics of tobacco are better.Conclusion:In the process of tobacco fertilization,fertilizer balance should be controlled,and the application of the proposed balanced fertilization technology can promote tobacco production and increase its net profit.
