First, the production of whole plant corn silage with ears
After harvesting the entire corn plant including the ears, the stalks are chopped into pieces of 2 to 3 cm in length. A layer of about 15 to 20 cm of dry hay is first placed at the bottom of the silo. Then, the chopped corn stalks are layered into the silo using a shovel. Every 20 cm of material is compacted using a tractor to ensure density. The stored material should be 50 to 60 cm higher than the silo’s opening. The shape of the pile should resemble a curved ridge, with a lower center and higher sides. Once filled, the corn stalks are tightly covered with 2 to 3 layers of plastic film. A layer of wet soil, 20 to 30 cm thick, is then placed on top to create an airtight seal.
Second, the production of fresh corn straw silage
The corn stalks are cut into 2 to 3 cm pieces using a silking machine. They are then filled into the silo in layers, each about 15 to 20 cm thick. The process continues until the material extends more than 60 cm above the silo’s mouth. After filling, the material is tightly covered with plastic film and sealed using wet soil to prevent air from entering. This ensures proper fermentation and preservation of the forage.
Third, the production of dry corn stalk microbial silage
Dry corn stalks that have not been mold-dried are first crushed into 2 to 3 cm lengths using a silking machine. A microbial agent is prepared according to the ratio of 1000:3:7:800~1000 (straw, live bacteria, strain, water) using products from Xi'an Xintiandi. A small amount of white sugar is also added to enhance microbial activity. The dried straw is then layered into the silo, with the microbial solution and water sprayed evenly over each layer—approximately 110 to 120 kg of fresh water per ton of dry straw. Each layer is about 20 to 30 cm thick, and the process continues until the pile reaches 50 to 60 cm above the silo’s opening. A layer of salt is sprinkled on top (about 250 g per square meter), followed by covering with plastic film and sealing it with 15 to 20 cm of soil.
Fourth, the production of dry corn stalk yellow stockpile
Dry corn stalks that have not been mold-dried are first cut into 2 to 3 cm pieces using a twisting machine. Water is then added at a rate of 110 to 120 kg per ton of dry straw to bring the moisture content up to around 65%. The material should feel moist but not dripping when squeezed. Additives such as 30 kg of urea and 2.5 kg of salt per ton of straw are mixed in during the layering process. The straw is filled in layers, each about 20 to 30 cm thick, until the pile is 60 cm above the silo’s mouth. Finally, a 30 cm layer of soil is placed on top to seal the pile and protect it from air exposure.
