棉柴部分代替棉籽壳栽培杏鲍菇技术研究

Cultivation of Pleurotus eryngii with Cotton Stalk Instead of Cottonseed Hull

[目的]寻求价格低廉的物料代替棉籽壳栽培杏鲍菇,降低杏鲍菇培养料的成本。[方法]以杏鲍菇1218为试验材料,以棉籽壳为主的培养料为对照,采用一定比例的棉柴替代棉籽壳设置不同的培养料配方处理,研究不同棉柴比例对菌丝生长速度和鲜菇产量的影响。[结果]以棉柴40%、棉籽壳40%、麦麸15%、豆饼粉3%、石膏粉1%、石灰粉1%为配方的培养料处理经济效益最高,产投比为2.28。[结论]该研究可为杏鲍菇生产提供新的思路。

Objective] To find a cheap material to replace cottonseed hull for the cultivation of Pleurotus eryngii, and to reduce the cost of cul-ture medium for P.eryngii.[Method] With P.eryngii 1218 as the test material, cultivation material mainly containing cottonseed hull was used as the control.A certain proportion of cotton stalk was used to take the place if cottonseed hull, so as to design the substrate composition.Effects of cotton stalk proportion on the hypha growthand fresh mushroom yield were studied .[ Result] The optimal substrate composition was 40% cot-ton stalk, 40% cottonseed hull, 15% wheat bran, 3% bean powder, 1% gesso, and 1% lime powder.It could obtain the maximum economic benefit; and the ratio of output-input was 2.28.[Conclusion] This research provides new idea for the production of P.eryngii.
