[ Method] The inhibition rate of sea brine against F. gram/nearum was measured using mycelial growth rate method. The inhibition effect of sea brine against infection of F. gram/nearum on maize was measured through leaf culture method in vitro. [Result] With the decrease of sea brine concentration, its inhibition against F. gram/nearum had no remarkable regulation, which first decreased, then increased, and finally decreased. It had the best inhibition effect as the concentration was 0.005 0% with the inhibition rate of 31.2%. 0.050 0% sea brine had the best inhibition effect against the infection of F. graminearum with the inhibition rate of 44.3%. [ Conclusion] The results provided theoretical basis for the application of sea brine in the aspects of plant diseases and vests control展开更多

And mycelial growth rates of P1, P0 and CK1 were 5.8 mm/d,?3.66?mm/d,?and?4.66 mm/d on 3rd?day, respectively. The growth rates?of?Pleurotusgeesteranus?of C1, CK2 and P0 were 9.0 mm/d,?11.66 mm/d,?and?4.00 mm/d on 3rd?day, respectively. So the degree of fermentation of the substrate could be determined within 3 days according to the mycelial growth rate. As the growth of edible fungi?is?affected by degree of fermentation of the substrate and there is little literature on degree of fermentation of edible fungi substrate, the study will provide theoretical and technical basis for determination of substrate fermentation.展开更多
