文章摘要為嘗試將蘑菇培養(yǎng)土制成生物炭來(lái)改善生物肥料的品質(zhì),重點(diǎn)考察了添加蘑菇培養(yǎng)土生物炭對(duì)豬糞堆肥的物化特性影響。結(jié)果表明:在500℃下熱解制備的蘑菇培養(yǎng)土生物炭分別以0豫、5豫、10豫、15豫(W/W)的比例與豬糞混合堆肥后,顯著降低了堆肥的電導(dǎo)率、初始含水率和有機(jī)物的損失量;堆肥中 Ca 與 K 的含量與添加生物炭沒(méi)有太大的相關(guān)性,N 的含量與生物炭添加比例具有很好的正相關(guān)性,P 與 Mg 的改變量則隨著生物炭添加比例的增加呈現(xiàn)下降趨勢(shì)。水稻栽培實(shí)驗(yàn)結(jié)果表明施用生物炭能有效促進(jìn)水稻生長(zhǎng),稻穗(干重)最多可增產(chǎn)49豫。

AbstrSpent mushroom substrate(SMS), a bulky waste byproduct of commercial mushroom industry, has caused environmental pollu-tion. In this work, biochar derived from SMS was added to pig manure at a rate of 0, 5%, 10% and 15%(W/W)to investigate its effects on the physic-chemical properties of pig manure during composting and rice growth. Adding SMS-derived biochar significantly reduced elec-trical conductivity, initial moisture content and organic matter loss of the compost. The biochar additions significantly increased the N con-centrations in the compost, but had no obvious effects on the concentrations of Ca and K. The concentrations of P and Mg in the fertilizer in-creased as compared to the control, but the increments decreased with increasing amount of the biochar. Applying SMS-derived biochar ef-fectively promoted rice growth and increased the grain yield by 49% at 5% biochar.
