Research on the Cultivation Technology of Pleurotus citrinipileatus using Salix psammophila Sawdust
Salix psammophila is a windbreak and sand-fixing tree species in Northwest China,and its flat stubble branches are high-quality biomass resources.In order to rationally develop the branch resources of Salix psam-mophila and explore new ways for the development of sand industry,this study used the sawdust of Pleurotus citri-nipileatus branches as the main cultivation substrate to carry out Pleurotus citrinopileatus,and seven cultivation sub-strate formulations were formed by adjusting the composition of the sawdust from Salix psammophila,and the tradi-tional corncob material formula was used as a control(corncob 82%,wheat bran 15%,corn flour 1%,soybean meal 1%,and gypsum 1%).The growth of mycelium and the phenological properties and yield of the substrate of differ-ent formulations were compared to explore the feasibility of cultivating Pleurotus citrinipileatus with sawdust from Salix psammophila.The results showed that Pleurotus citrinipileatus grew on the substrate of Salix psammophila sawdust formula and produced fruiting bodies normally.When the formula 2(Salix psammophila sawdust 87%,wheat bran 10%,corn flour 1%,soybean meal 1%,and gypsum 1%)was used to cultivate Pleurotus citrinopilea-tus,the mycelium grew well,the mycelial contamination rate was only 4%,the single bag yield was 0.39 kg,the bioconversion rate was 77.40%,and the single bag profit was 2.38 yuan.The measurement indexes were better than the control.The mycelial contamination rate of the control reached 5%,the yield of a single bag was only 0.37 kg,the bioconversion rate was 74.09%,and the profit of a single bag was 2.24 yuan.The bioconversion rate of other for-mulations was lower than that of formula 2,and the lowest conversion rate was 71.01%of formula 7(Salix psam-mophila sawdust 62%,wheat bran 35%,corn flour 1%,soybean meal 1%,and gypsum 1%).It is feasible to use the sawdust of Salix psammophila branches as the cultivation substrate for Pleurotus citrinipileatus,and explore a new path for the full development and utilization of Salix psammophila resources.
