以玉米秸秆栽培糙皮侧耳后产生的菌糠制作出的有机肥为底肥进行玉米室内盆栽试验,结果表明:施加糙皮侧耳菌糠肥料对玉米苗期的生长发育具有一定的促进作用,每 1 kg 土壤中添加12 g菌糠肥料培育的玉米苗期株高比对照增加 18%,地上部鲜质量比对照增加 23.27%,地上部干质量比对照增加 23.89%,叶绿素含量与光合作用速率也有显著提升;同时,施加糙皮侧耳菌糠肥料可使土壤有机质含量、土壤电导率、土壤阳离子交换量、土壤速效养分以及土壤全量养分均有增加,并降低了土壤pH值.
Effects of spent Pleurotus ostreatus substrates fertilizer on maize seedling growth and soil properties
Using the organic fertilizer made from spent mushroom substrates produced after the cultivation of Pleurotus ostreatus with corn straw as the base fertilizer,the indoor pot experiment was carried out.The results showed that the application of spent mushroom substrates fertilizer had a certain promoting effect on the growth and development of maize seedlings stage.Compared with the control group,the plant height of maize seedlings cultivated with 12 g spent mushroom substrates fertilizer per kilogram of soil was increased by 18%,the aboveground fresh weight was increased by 23.27%,the aboveground dry weight increased by 23.89%,and the chlorophyll content and photosynthetic rate also increased significantly.The further test results showed that the application of spent Pleurotus ostreatus substrates fertilizer increased the content of soil organic matter,soil conductivity,soil cation exchange capacity,soil available nutrients and soil total nutrients,and could decrease the pH value of soil.
