Abstract

Abstract:

The paper aims to utilize abandoned tobacco straw and improve its utilization rate effectively, so as to make tobacco plants grow healthier. In this study, the enzyme solution made from the common abandoned tobacco straw in field was used to mix with the screened actinomycetes, Streptomyces griseochromogenes, and the effects of mixed enzyme solution on the growth and development of tobacco seedlings and tobacco plants at seedling and harvest stage were studied. The results showed that: the application of tobacco enzyme solution could increase the yield and quality of tobacco and the ratio of tobacco to superior tobacco; among them, the mixed application of tobacco enzyme solution and S. griseochromogenes had the best effect, which was superior to other treatments and significantly superior to the control. The method of mixing tobacco enzyme solution with antagonistic actinomycetes can be recommended for tobacco production, which not only reduce the accumulation of pathogens caused by abandoned straw in field, but also effectively improve the yield and quality of tobacco.

Key words: enzyme solution, flue-cured tobacco, straw, actinomycetes, growth and development
