摘要
以水稻秸秆为原料,用不同浓度CaO溶液浸泡、发酵预处理,将其用于大球盖菇畦地栽培,探讨对大球盖菇畦地栽培最有利的水稻秸秆预处理工艺.结果表明:秸秆经CaO浸泡并发酵处理后,外形变得细碎,表面较粗糙,边缘破损,内部组织结构暴露且坍塌.2.5％CaO浸泡并发酵处理的秸秆纤维素、半纤维素和木质素含量分别较清水处理低37.18％、25.30％和38.00％.随着大球盖菇的生长发育,秸秆逐渐块化,失去完整结构,大面积坍塌,出现碎片和深沟,且秸秆纤维素、半纤维素和木质素含量显著下降.秸秆经2.5％CaO浸泡并发酵处理,将其作为栽培原料,大球盖菇总产量和单位面积产量分别较清水浸泡处理高42.73％和42.81％.综上,水稻秸秆用低浓度且廉价的2.5％CaO浸泡并堆砌发酵,是最利于大球盖菇畦地栽培的预处理工艺.
Abstract
To discuss rice straw pre-treatment process that is the most appropriate for furrow cultivation of Stropharia rugosoannulata Farl.ex Murrill.Rice straws were used as raw material and soaked,fermented in different concentrations of CaO solution,which were used to cultivate S.rugosoannulata Farl.ex Murrill onfurrow.The straws became finely ground,their surface was rough,their edges were broken,and the tissue structure in them was exposed and collapsed af-ter they were soaked in CaO and fermented for treatment.After the straws were soaked in 2.5％CaO and fermented,the cellulose,hemicellulose,and lignin content was 37.18％,25.30％,and 38.00％lower than that in straws treated with water,respectively.The straw eventually changed into lumps,lost its entire structure,collapse in a big area,and had fragments and deep grooves as S.rugosoannulata Farl.ex Murrill grows and develops.The cellulose,hemicellulose,and lignin content in the straw obviously reduced.After they were soaked in 2.5％CaO and fermented,the straws were used as raw materials for cultivating.The S.rugosoannulata Farl.ex Murrill total yield and per unit yield were 42.73％and 42.81％higher than those soaked in water,respectively.Consequently,soaking rice straw in 2.5％CaO with a low con-centration and low price forfermentation is a favorable pre-treatment process for furrow cultivation of S.rugosoannulata Farl.ex Murrill.
