玉米芯颗粒度对杏鲍菇菌丝生长及产量的影响

摘要

分析了不同玉米芯颗粒度对工厂化生产杏鲍菇菌丝生长速度、单产、生物学效率以及生长周期的影响.结果表明:单一玉米芯颗粒度试验中,随着玉米芯颗粒度的增大,菌丝生长速度与单产明显增加,X1配方单产为133.29±7.91 g,与对照相比,产量增加10.56%,而颗粒度过低则会导致生长周期延长.不同玉米芯颗粒度混合试验中,M3、M4配方单产分别为131.83±4.02 g、133.63±5.53 g,与对照相比,产量分别增加9.36%和10.85%.%The effects of corncob particle size in the substrate were analyzed on the mycelium growth rate, yield per bottle, biological efficiency and growth cycle of Pleurotus eryngii in factory production. The results showed that the mycelium growth rate and yield per bottle increased significantly with the corncob particle size increasing in single corncob particle size tests, the X1 formula yielded averagely 133.29 ± 7.91 g a bottle which was 10.56％ higher than CK,and the excessively small corncob particles could result in lengthening the growth cycle. In mixed corncob particle size tests, the M3 and M4 formulae yielded averagely 131.83 ± 4.02 and 133.63 ± 5.53 g per bottle, respectively increasing by 9.36％ and 10.85％ over CK.
