An exploration has been conducted in this paper on the effects of double-row concave ridge cultivation technique on yields and quality of mountainous flue-cured tobacco.Yunyan 87has been selected as the test material with the conventional single-row ridge cultivation as the control of the small-scale field test.Plant height,stem girth,nodal distance,leaf population,size of leaf,root development,yields,output value and chemical constituents of flue-cured tobacco have been compared between different ridge patterns.The results show that double-row concave ridge cultivation is superior to single-row ridge cultivation on enhancing yield growth vigor,improving quality,yields and output value,so that the double-row concave ridge cultivation technique can be popularizated and applicated on the base of further improvement and standardization.
