The first seminar on tobacco film mulching was held in Qingdao from January 10 to January 13, 1986. The meeting was hosted by the Tobacco Science Group of the Film Research Institute and participated in by 16 scientific and technological personnel engaged in tobacco mulch cultivation in 12 provinces. The meeting exchanged experiences and lessons learned from tobacco film mulching over the past several years and covered the changes of soil temperature and water status under different film mulching conditions and the impact of these changes on tobacco growth and tobacco quality. Through discussion, it is generally clear that the appropriate size, coverage and application of nitrogen fertilizers under different ecological conditions; how to improve the quality of tobacco leaf by plastic film mulching cultivation;
