Fermentation formula of dry corn stalk

According to the actual situation in rural areas, corn straw fermentation can be divided into two methods: natural fermentation of manure and urea wheat bran fermentation.

The first method is that in the south of China, when people feed pigs, there is a septic tank, which is a mixture of pig feces and urine, plus fecal water soaked in water for a long time. Pour this manure on chopped corn stalks, stir thoroughly, and then pile it up less than one meter high. Then cover it with a thin layer of practical soil and let it ferment naturally. In this way, after five months, sowing in the next spring can be used as base fertilizer.

Another method is suitable for rapid fermentation of wheat bran urea without manure. This method is relatively troublesome. The practice is to use 1 kg starter, 5 kg wheat bran and 3 kg urea per 1000 kg corn stalk segment. First, dilute urea with 3% aqueous solution for later use. When stacking corn stalks, sprinkle or spray the above additives every 20 cm thick, then water them and cover them with thicker plastic film. In this way, the pile should be turned every 15 days, and the water should be continuously sprinkled when turning. After three rounds of fermentation, it was basically completed. If it is not used in time, continue to pile, the longer the better.
