preparation example Construction
[0045] Described biological fertilizer preparation method comprises the following steps:
[0046] S1: drying the crop straw and crushing it with a pulverizer to obtain straw powder;
[0047] S2: Evenly mix straw powder, poultry and livestock manure, domestic sludge and biological bacteria according to parts by weight to obtain a mixture, and then put the mixture into a fermentation tank and ferment for 15-18 days to obtain a fermented material; In the process, dissolve the biological agent in water, make a solution and add it;
[0048] S3: On the basis of step S2, pulverize the vermiculite, diatomaceous earth and weathered coal and mix uniformly to obtain a powdery conditioner. Afterwards, add an appropriate amount of water to the powdery conditioner and diammonium hydrogen phosphate and stir evenly. Send it into the fermentation material and mix it evenly for secondary fermentation. The fermentation time is 5-10 days;
[0049] S4: On the basis of step S3, sending the fermen...
