Study Effects of Organic Induced Antivirotic Dry Mycelium of Penicillium chrysogenum(DMP) on Breeding Robust Seedlings and Increasing Yield

Flue-cured tobacco is tested by using dry mycelium of Penicillium chrysogenum(DMP) during seedling-stage and field period to study the impact.The results showed that 12 disc the nursery matrix are even mixed with 188 g(i.e.1 875 g / hm2) DMP during the tobacco seedling stage which got the minimum influence on seedling emergence rate and improved living percentage and quality of tobacco seedlings.And there is evidence that DMP treatment can improve the resistance in tobacco seedling stage against black shank,black root rot and virus disease.In the field period and 15 days after transplanting,750 g / hm2and 2 250 g / hm2DMP were used respectively,it can effectively control black shank,black root rot and virus disease and improve the production and quality of tobacco leaf.
