The suitable medium formula was selected, namely 50 g of potato, 20 g of glucose, 1.5 g of peptone, 1 g of KH2PO4, 0.5 g of MgSO4, 10 mg of Vitamin B1, 1000 mL of water, and natural pH. On this basis, four factors were designed, including shaking table speed, vitamin B1 addition concentration, bottling volume of culture medium, and settling time before shaking, to conduct comparative experiments on V. volvacea liquid strain shaking table cultivation. The results showed that the most suitable shaking table speed for the cultivation of V. volvacea liquid strains was 130 r/min;the optimal concentration of added vitamin B1 was 15 mg/L;the optimal filling volume for a 250 mL conical flask and culture medium was 80 mL;the best effect was to let the culture medium stand for 36 hours before shaking it on a shaker.展开更多
采用摇床培养的方法,以菌丝球的生物量为评价指标,通过单因素试验和正交试验,说明Zn、Fe、Mn、Cu 四种矿质元素对茶树菇液体菌丝生长的影响。结果表明:Zn、Fe、Mn、Cu四种矿质元素对茶树菇液体菌种菌丝生长具有促进作用,其中Zn对茶树菇...采用摇床培养的方法,以菌丝球的生物量为评价指标,通过单因素试验和正交试验,说明Zn、Fe、Mn、Cu 四种矿质元素对茶树菇液体菌丝生长的影响。结果表明:Zn、Fe、Mn、Cu四种矿质元素对茶树菇液体菌种菌丝生长具有促进作用,其中Zn对茶树菇菌丝生长的影响最明显,其次为Fe、Mn、Cu。这四种矿质元素可以通过单独添加发挥作用,也可以混合添加共同作用,混合添加比单独添加效果更好,促进茶树菇菌丝生长的最优组合是0.25 g/L ZnSO4·7H2O,0.30 g/L FeSO4·7H2O,0.20 g/L MnSO4·H2O,0.15 g/L CuSO4·5H2O。Using the shaking table cultivation method and using the biomass of mycelium balls as the evaluation index, single factor experiments and orthogonal experiments were conducted to illustrate the effects of four mineral elements, Zn, Fe, Mn, and Cu, on the liquid mycelial growth of Agrocybe aegerita. The results showed that four mineral elements, Zn, Fe, Mn, and Cu, had a promoting effect on the mycelial growth of liquid Agrocybe aegerita strains. Among them, Zn had the most significant effect on the mycelial growth of Agrocybe aegerita, followed by Fe, Mn, and Cu. These four mineral elements can exert their effects by adding them alone or by mixing them together. The mixed addition has a better effect than adding them alone. The optimal combination to promote the mycelial growth of Agrocybe aegerita is 0.25 g/L ZnSO4·7H2O, 0.30 g/L FeSO4·7H2O, 0.20 g/L MnSO4·H2O, and 0.15 g/L CuSO4·5H2O.展开更多
为了充分利用广西丰富的农业资源,提高农业综合效益,以木薯秆为主要原料,以桑枝杆作为对照,设置木薯秆的占比分别为70%、55%、40%等三组,每组再设置三个处理,共9个处理,进行赤芝栽培试验,探讨木薯秆栽培赤芝的可行性和高产优质的栽培配...为了充分利用广西丰富的农业资源,提高农业综合效益,以木薯秆为主要原料,以桑枝杆作为对照,设置木薯秆的占比分别为70%、55%、40%等三组,每组再设置三个处理,共9个处理,进行赤芝栽培试验,探讨木薯秆栽培赤芝的可行性和高产优质的栽培配方,结果表明:利用木薯秆作为主要原料栽培赤芝是可行的,单独以木薯秆作为碳源,或在木薯秆中添加适当的桑杆、甘蔗渣,均能获得较好的栽培效果,其中,在木薯秆中添加30%的甘蔗渣栽培效果最好。In order to fully utilize the abundant agricultural resources in Guangxi and improve the comprehensive agricultural benefits, cassava stalks were used as the main raw material, and mulberry branches were used as the control. Three groups of cassava stalks were set with proportions of 70%, 55%, and 40%, respectively, and three treatments were set for each group, for a total of nine treatments. The cultivation experiment of Ganoderma lucidum was conducted to explore the feasibility of cultivating G. lucidum with cassava stalks and the high-yield and high-quality cultivation formula. The results showed that using cassava stalks as the main raw material to cultivate G. lucidum was feasible. Using cassava stalks as a carbon source alone or adding appropriate mulberry stalks and sugarcane bagasse to cassava stalks could achieve good cultivation effects. Among them, adding 30% sugarcane bagasse to cassava stalks had the best cultivation effect.展开更多
