[Objective] The purpose was to study the effect of plastic-bag cultivation of Lentinus edodes with apple tree branch litters as main materials.[Method] With apple tree branch litters as main materials,the plastic-bag cultivation of Lentinus edodes was conducted continuously in 2000~2004.The growths of L.edodes mycelia were observed and the yield and benefit were counted when it was harvested.[Result] In the plastic-bag cultivation of L.edodes with apple tree branch litters,the mycelia grew quickly,with the growth speed averaging 0.58～0.65 cm/d and low contamination rate(7.14 %～9.60 %).The mycelia had high yield.It could be picked 6~8 flushes averagely and the products of the first 3 flushes were higher.Its biological transformation rate was 122.50 %～139.28 % and net profit per bag was 11.40～17.20 yuan,so the economic benefit was obvious.[Conclusion] Using the plastic-bag cultivation of L.edodes with apple tree branch litters,the mycelia grew quickly,with lower contamination rate,high yield and obvious economic benefit.Its biological transformation rate was up to 139.28 %,with low cost,broad raw material sources and broad application prospect.
