Abstract:

The effect of mulberry straw substrates on fruiting traits of Lentinus edodes was explored. ‘Ming60’ was taken as the L. edodes variety, and conventional sawdust formula was used as the control, including 80% sawdust, 18% bran, 1% gypsum and 0.5% mushroom element. Mulberry straw substituting sawdust with different proportions of 5%, 15%, 25%, 35%, 50%, 75% and 100% were set in this experiment to broaden the practical scope of mulberry straw substrates for edible fungi cultivation. The results showed that the average mycelium growth rate presented a trend of increase first and then decrease along with the increase of substitution rate. Time from inoculation to end of mycelia, fresh mushroom production per bag, pileus weight, pileus thickness, pileus diameter, stipe length, and fruit body weight were inversely proportional to mulberry straw substitution rate, but the mushroom shape and color were not affected. And at the same time, when the proportion of mulberry straw substitution was 5%-50%, the growth traits, commodity characteristics and economic benefit of mushroom were significantly better than those of the control group, and the effect reached the best when the proportion of mulberry straw substitution was 15%.
