In addition to feeding cattle, corn stalks can be used to make pollution-free farmyard fertilizers. In order to ensure the quality of corn straw fertilizer, the following points should be noted during the composting process. First, do a good job of corn stalk processing. The corn stalks are first cut into 3 to 4 cm lengths, and they can also be comminuted with a pulverizer and soaked with excrement to make them suitable for soaking. Second, the raw material ratio should be appropriate. Composting corn stalks and improving the ratio of raw materials for fertilizer efficiency are critical. Shredded corn stalks, soil, livestock manure, human waste, and preparation ratios of 6:1:2:1 were mixed and homogenized for composting. The ratio of straw and water is 1:3. Third, strictly control the temperature inside the reactor. During the fermentation, the temperature should be controlled between 50°C and 60°C, which is most favorable for the microbial decomposition of fibrous bacteria. Four, after about 10 days, it will be overturned twice. After that, it will be poured once every 7 days and it will fall 3 to 4 times. 5. Adjust the acidity of the heap in time. The microorganisms in the heap are suitable for activities under neutral and slightly alkaline conditions. When the acidity is too large, a small amount of lime or ash can be added in an appropriate amount. The corn straw fertilizer thus composted can reach the quality standard after 25 to 30 days.
