Abstract

Abstract:

In order to clarify the regulatory effects of nitrogen reduction combined with microbial agents on dry matter and nitrogen, phosphorus, and potassium nutrients in flue-cured tobacco, a two-factor experiment was designed using ‘Yunyan 87’ as an example to compare the differences in dry matter accumulation and distribution, nitrogen, phosphorus, and potassium nutrient accumulation and distribution, and fertilizer utilization efficiency among different treatments of flue-cured tobacco. The contribution rates of fertilization patterns, microbial agents, and their interactions to the accumulation of dry matter, nitrogen, phosphorus, and potassium nutrients, and fertilizer utilization efficiency in flue-cured tobacco were analyzed using η² method. The results showed that nitrogen reduction combined with microbial agents could increase the accumulation of dry matter and nitrogen, phosphorus, and potassium nutrients in flue-cured tobacco, improve accumulation efficiency, utilization efficiency, and absorption efficiency, and improve the production efficiency of nitrogen fertilizer tobacco. The contribution rates of fertilization modes, microbial agents, and their interactions to dry matter accumulation were 41.90%, 29.34%, and 28.76%; the contribution rates to nitrogen accumulation were 41.98%, 27.49%, and 30.53%; the contribution rates to phosphorus accumulation were 34.63%, 34.47% and 30.90%, respectively; and the contribution rates to potassium accumulation were 24.17%, 32.95%, and 42.87%. In the southern rainy tobacco region, adopting a nitrogen reduction fertilization model of reducing the proportion of base fertilizer and applying base fertilizer in holes, coupled with applying microbial agents, can improve the accumulation of dry matter and nutrients in tobacco leaves and improve fertilizer utilization efficiency, which is conducive to promoting the early growth and rapid development of flue-cured tobacco in rice stubble.

Key words: nitrogen reduction fertilization, microbial agents, flue-cured tobacco, dry matter accumulation, nutrient accumulation, fertilizer utilization efficiency
