Second, preparation of fertilizer materials (take 1 ton dry straw as an example). 1 1,000 kg of crop stalks. 2 baking powder 20 kg. Peanut cakes, bean cakes, cottonseed cakes, rapeseed cakes, etc. can be used. No cake powder can be replaced with 10 kg urea. 3 KFC Green Fermentation Bacteria 1 kg.

Use shovels and other tools to mix and pour them into a strip that is 2 meters wide, 1.5 meters high, and unlimited in length.
Fourth, the straw decay process. 1 warming phase: from normal temperature to 50 Â°C, usually only one day. 2 High temperature stage: Generally only 2 days from 50-70Â°C. 3 cooling phase: from high temperature down to below 50 Â°C, usually about 10 days, when the straw fertilizer process is basically completed, fertilizer can be directly applied.

(2) Straw manure is very rich in organic matter, nitrogen, phosphorus and potassium are relatively balanced, and also contains various trace elements.
