【摘要】 對生產(chǎn)上已采完1潮菇的杏鮑菇(Pleurotus eryngii)廢菌棒進行及時補充營養(yǎng)L9(34)正交試驗研究。試驗結(jié)果表明補營養(yǎng)效果明顯好于僅補水的對照。大多數(shù)試驗配方處理均較對照現(xiàn)蕾和成熟早、生物轉(zhuǎn)化效率和產(chǎn)量高。以2潮菇子實體產(chǎn)量和補液總成本作為綜合評價指標,應用Fuzzy變換進行正交優(yōu)化分析,得到產(chǎn)量高且成本低的最佳補充營養(yǎng)液配方為:葡萄糖2.5%,蛋白胨0.6%,酵母膏0.2%,KH2PO40.06%(MgSO4.7H2O 0.06%)。4個營養(yǎng)因素對綜合評價指標的影響次序是:KH2PO4>酵母膏>蛋白胨>葡萄糖。
【Abstract】 Orthogonal testing [L9(34)] was adopted for optimizing the composition of a nutritional supplement used to augment Pleurotus eryngii compost following the initial harvest of fruit bodies.Nutritional supplementation resulted in shorter primordia formation and fruit body maturation times,and higher fruit body yields,in a subsequent developmental cycle.These effects were especially evident when the compost was supplemented with(w/w) 2.5% glucose,1.2% peptone,0.1% yeast extract and 0.06% KH2PO4.Fuzz...
