不同接种量对早秋玉米芯发酵料及发酵半熟料栽培平菇的影响

摘要

为确定平菇栽培的最佳接种量,分别以玉米芯发酵料和发酵半熟料为栽培基质,研究不同接种量对早秋季节平菇栽培的茵丝长势、污染率、茵丝满袋时间、首次采菇时间、子实体特征和产量、生物学效率、原料成本、菌种成本、产品销售价格及利润率的影响.结果表明:利用玉米芯发酵料栽培平菇茵株新831,接种量为栽培干料质量的13.6％时,平均生物学效率为74.99％,利润率最高,为158.41％;利用发酵半熟料栽培平菇茵株99,接种量为栽培干料质量的4.4％时,平均生物学效率为91.99％,利润率最高,为281.99％.不同的接种量,生产出的平菇子实体形态无明显变化.%In order to determine the optimum inoculation amount of Pleurotus ostreatus cultivation,the fermented corncob compost and semi-processed materials were used as culture substrate.The influence of different inoculation amount on the growth of hyphae,pollution rate,hyphal pocketful time,the first harvesting time,mushroom fruiting characteristics and yield,biological efficiency,the cost of raw materials,strain cost,the product sales price and profit rate in early autumn cultivation of Pleurotus ostreatus were studied.The results showed that when Pleurotus ostreatus strain(new 831) was cultivated by fermented corncob compost and the inoculation amount was 13.6％ of cultivated dry weight,the average biological efficiency was 74.99 ％,with the highest profit margin of 158.41~when Pleurotus ostreatus strain(99) was cultivated by fermented and semi-processed materials and the inoculation amount was 4.4％ of cultivated dry weight,the average biological efficiency was 91.99％,with the highest profit margin of 281.99％.The morphology of new produced fruiting body had no obvious change under different inoculation amount.
