Silage is a method of long-term preservation of the nutrition of green and juicy succulent using the fermentation of microorganisms (mainly lactic acid bacteria). (1) Site selection and pit construction: The pit site should be selected on the ground with high groundwater, low groundwater level, good water conditions, and sunny space. Cellar type generally uses rectangular underground passengers. When digging pits, a depth of 1.5 meters and a cellar width of about 2 meters are more appropriate. The wall of the cellar and the bottom of the cellar should be smooth and solid, with round corners. The cellar length will depend on the amount of cattle and silage. In general silages per cubic meter can be 500-600 kilograms of corn silage silage. (2) Corn stalk preparation: As corn silage used for silage, there must be a certain amount of moisture. Because the right amount of water is an important condition to ensure the normal activity of lactic acid bacteria. Excessively high and low water content will affect the silage fermentation process and the quality of silage Corn plants after harvesting the kernels on a monthly basis, generally retain about 20,000 green leaves, and their moisture content is about 70%, which is suitable for silage. If moisture is too high, it should be air-dried to lose some of its moisture. If the plants are too dry, spray water evenly during silage. In order to increase the amount of nitrogen, according to ID00 kg of corn stalks plus urea 3 ~ 5 kg, mixed and then packed. (3) Short compaction: As corn silage, especially dry corn stalks, it should be as short as possible. The purpose of the short is to facilitate the compacting during loading and the convenience of later retrieval. Generally it can be 2 to 3 centimeters long. When loading, you must do it with yours, fill with them, and follow the steps until they are full. Pay attention to the cellar side and the corners. The purpose of stepping on the solid is to make the air in the pits unreal, and the air in the pit is unreal, the air in the pit is too high, and the temperature in the pit is easy to rise, so that the sugar, vitamins and proteins in the corn stalk are damaged, resulting in loss of nutrients. In addition, the cellar temperature is too high, it is not conducive to the proliferation of lactic acid bacteria, on the contrary, will make a good breeding of spoilage bacteria, molds, etc., so that corn rot moldy, resulting in failure of silage. (4) Sealing pits: When filling up, make corn stalks 20-30 centimeters above the cellar surface, then spread a plastic sheet on top, and finally cover 50 centimeters of compacted soil. After the silo is sealed, in order to prevent the infiltration of rainwater into the pit, the pit should be ridged, and trenches should be drained about 1m away from the pit; after frequent inspections, if it is found to sink or crack, it should be sealed at any time. Enter with water resistance and air. (5) Utilization: 17 to 21 days after the production of silage can be used for passengers. To open the pit from one end, and from top to bottom, stratify the grass from outside to inside. After removal, straw or mats, plastic sheets, etc. should be covered in time to prevent exposure, freezing and preventing the second fermentation. When silage is started to be fed, it must be gradually increased from little to large, and fed and fed according to the amount of feed.
