However, the annual loss caused by natural disasters such as low temperature and rain, rainstorm and flood, high temperature and drought, and hail accounts for about 20%, and they have become one of the important factors restricting the development of tobacco industry in Luzhou. In recent years, a lot of work has been done in disaster prevention and mitigation in the process of flue-cured tobacco production, and cer-tain results have been achieved. However, it still needs further exploration and research in the face of natural disasters that are gradually changing frequently and even develop in a normal way. In this paper, common meteorological disasters in the tobacco-growing areas of Luzhou were ana-lyzed firstly, and then corresponding countermeasures were put forward, which is of great significance to ensure the sustainable and healthy devel-opment of tobacco in Luzhou.展开更多

The results showed that the agronomic traits and biomass of flue-cured tobacco in the three treatments were higher than that of the control group,and the mixed application of different organic fertilizers made from distiller＇s grains and compound fertilizer could promote the growth and development of flue-cured tobacco significantly.展开更多

The results showed that when 60% of humic acid was added to the distiller s grain substrate made from coarse distiller s grains, fine distiller s grains, perlite and vermiculite, both the pH and electrical conductivity decreased significantly and were similar to that of the conventional substrate. Moreover, the emergence rate of tobacco seedlings, the rate of strong tobacco seedlings, leaf number, stem height, root growth and quality of tobacco seedlings were good.展开更多
