[0014] Taking the corn stalk-oyster mushroom-chicken (egg)-leek selenium-enriched production system as an example, the specific steps are as follows:
[0015] 1. Pulverize the corn stalk, add urea 10g / kg, sucrose 5g / kg, superphosphate 2g / kg, gypsum 1g / kg, sodium selenite 20~50mg / kg, adjust the moisture content to 60%~70 %, the pH is 6.5-8.0, and fermentation is performed, and sodium selenite can also be added after fermentation to obtain a selenium-enriched fermentation substrate.
[0016] 2. Put the fermented selenium-rich fermentation substrate into a cultivation bag for inoculation. The cultivation bag is generally made of polyethylene or polypropylene plastic bags, and different specifications are used in different seasons: late summer and early autumn can be selected (20-22) cm×(40~45)cm specification, (24~25)cm×(45~50)cm specification for autumn cultivation, (25~26)cm×(50~52)cm specification for late autumn and early winter, winter (25~29)cm×(50~55)cm can be selected. ...
