چکیده

قارچ خوراکی شیتاکه یک قارچ نسبتاً معطر بوده و روی انواع مختلفی از چوب­های مرده دارای بافت سخت رشد می­کند و از لحاظ تولید کل سالیانه در جهان در رتبه دوم قرار دارد. از سوی دیگر، هزاران تن ضایعات کشاورزی هر ساله سوزانده شده یا دور ریخته می­شوند. از این‌رو، به منظور ارزیابی امکان تولید قارچ شیتاکه روی ضایعات کشاورزیآزمایشی فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار طراحی گردید. در تحقیق حاضر، از کاه جو، ارزن و گندم به­عنوان بستر اصلی و خاک ­اره با نسبت 10 و 20 درصد به­صورت ترکیبی استفاده شد. نتایج نشان داد که بیشترین کارآیی بیولوژیکی به­ترتیب روی بستر کاه جو (14/88 درصد) و کاه گندم همراه با 20 درصد خاک ­اره (37/83 درصد) و کمترین کارآیی بیولوژیکی روی کاه گندم (48/26 درصد) مشاهده شد. علاوه­ بر این، بیشترین عملکرد در کاه جو (9/125 گرم در 500 گرم وزن تر بستر) اتفاق افتاد. با وجود ­این، کمترین میزان عملکرد در کاه گندم (35/26 گرم در 500 گرم وزن تر بستر) مشاهده شد. در مجموع، نتایج پژوهش حاضر نشان داد که عملکرد و کارایی بیولوژیک در کاه جو و ارزن با افزایش سطح خاک ارّه افزایش یافت.

چکیده [English]

Edible shiitake mushroom is a relatively fragrant mushroom and grows on different types of dead hard woods. This mushroom ranks second in the world in total yearly mushroom production. On the hand, thousand tons of agricultural wastes are burned or discarded yearly. Hence, to evaluate the shiitake mushroom production possibility on agricultural wastes, an experiment designed based on completely randomized design with three replications. In this study, barley straw, millet straw and wheat straw used as main substrate with 10 and 20 percentage, respectively. The results showed that the highest biological efficiency were observed on barley straw (88.14 percent) and wheat straw with 20 percent sawdust (83.37 percent), respectively and the lowest biological efficiency were obtained on wheat straw (26.48 percent). In addition to, the highest yield was occurred on barley straw (25.28g/500g wet weight of substrate). However, the lowest yield observed on wheat straw (5.27g/500g wet weight of substrate), respectively. In general, the results showed that yield and biological efficiency of shiitake, on the barley and millet straw had increased as the level of sawdust boosted.
