Since September, corn in all parts of our province has entered the late growth stage and the harvest is coming soon. Compared to seeded corn, the processing of silage corn can be performed after the milk ripening period is reached. The silage method can preserve the corn stalks that are still green or green after Autumn harvest, and can preserve the nutrients well. The texture can be softened and has a fragrance. It can increase the appetite of cattle and sheep and effectively solve the Winter forage. The lack of. At the same time, the production of silage will save half the area of ​​land compared to stacking the same amount of hay, and it will also help prevent fire, rain, mildew, and eliminate crop pests on the straw. The following describes the technologies related to corn silage. The key technology for making silage is to provide necessary conditions for the propagation of lactic acid bacteria: First, in the process of preparation, the raw materials should be as short as possible, compacted and tightly packed in the pit to remove the air in the pit as much as possible. The second is that the moisture content of the raw material is about 75% (ie, when the water can be screwed out by hand and it cannot drop), it is most suitable for the propagation of lactic acid bacteria. Silage should be based on the green degree of corn stalk to decide whether to spray water. Third, raw materials must contain a certain amount of sugar, and generally the sugar content of corn stalks meets the requirements. First, processing and utilization. 1. Harvest time. Whole plant silage corn had the best castration between the end of milk-growing period and the early stage of wax-cooking, and the grain milk line reached 1 hour. 2. Silage production. At the time of harvesting, the combine harvester is generally used to cut the raw materials in the field during the cutting and then transported back to the silage. Silage should be filled with fashion, as short as possible, while filling the edge with a tractor and other machinery for rolling, remove air as much as possible, to ensure compaction, to avoid silage failure caused by mildew. To strengthen the seal and prevent air leakage, a plastic film can be placed around the cellar. Loading green feed should be layer by layer, each layer 15 to 20 cm thick, continue to fill after mechanical compaction, especially the four corners and the wall should be practical. Second, pay attention to matters. 1. Strictly sealed cellar. When the raw materials are stored in the cell mouth above the centimeter, they can be covered and sealed. The first layer of straw or soft grass can be covered with a layer of 20-30 cm in thickness. When the plastic film is covered, the soil can be covered with 30-50 cm. Made of bread-shaped head, digging drainage ditches around the cellar to prevent rainwater from seeping into the pit. 2. Check often. Cracks in the pit shall be timely compacted with earth coverings to prevent seepage and rainwater. If natural sinking or cracking is found, seals shall be added in time to prevent entry of water, air intake, and entry into the rat, affecting the quality of the silage. 3. Open the cellar to take the material. It should be carried out after 40 days of silage. After the frost has fallen and the beginning of winter, it is followed by feeding and feeding.
