The texture of most paddy soil in South-Anhui is clayey, which is unfavorable for tobacco growth, thus, rice-husk was added into the cultivated-horizon of paddy soil to explore its effects on soil texture and tobacco production. The results showed that: 1) with the increase of added amount of rick-husk, the contents of 0.02-2mm soil particles and soil organic matter increased, soil bulk density, water content and pH decreased, but the tendency became slow down with time. 2) adding rice-husk generally can promote tobacco yield, quality and economic income, and adding 20%-30% (Vrick-husk/Vsoil) was optimal for tobacco production.
