The potato block, stems and leaves or industrial by-products are pressed in an airtight environment. Through the action of lactic acid bacteria, a sweet and yellow green juicy sweetpotato silage is prepared, which is an important way to solve the winter green feed. The processing method can be used in crypt silage or bagged silage.
Crypt silage. Digging pits: Select leeward sunny, high-lying terrain, compact soil, convenient transportation, digging pits near the barn. The size of the pit is generally about 750 kg of silage per cubic meter. When the silage is low, the cylindrical cellar can be excavated. The cellar depth is 170 cm, and the diameter is 100 cm. The bottom of the cellar is pot bottom type. When the silage is large, the rectangular cellar can be dug. The cellar depth is 250 cm, the bottom width is 150 cm, and the cell mouth width is 200 In centimeters, the length of the pit depends on the amount of silage. Cellar walls should be smooth, crack-free, airtight, and watertight. If the groundwater level is high, half-cell pits can be used, and the pit bottom is at least 50 cm above the highest groundwater level in the year. The silo should be dug 1 to 2 days before the silage. The cellar should be cleaned around. The cement pool is better if the conditions are met. Operation technique: Take a section of the yam and squeeze the two ends by hand. However, it is suitable if it does not drip. After entering the cellar, grasp half of the material firmly and grip it, so that the water between the fingers can seep out but not drip. The silage of potato vines requires no sand, clean, fresh, and is 3-5 centimeters long. When storing the pits, first pad 7 to 10 cm of hay in the bottom of the pit, surrounded by a small amount of hay, each 15 to 20 centimeters thick, it is necessary to repeatedly press, the cellar and the four corners should be solid. When there is too little water in the raw material, add water as appropriate. The frags are thick and long, and they are too long. In addition to thinning, they must be sprinkled evenly after 1-2 times. The bottom layer of the cellar with water can be less, the upper layer can be more, and a small amount of water can be poured with a scoop or basin, and the uniform can be achieved. After filling the cellar, cover the top with a layer of grass or plastic sheeting about 10 cm thick, and then seal the soil. From the top of the pit to the surrounding area, the first 1 to 2 times the soil is 15 cm thick. If the soil is dry, it can be sprinkled properly. After the water is infiltrated, it can be filled with soil and then sealed. The final cellar is about 100 cm thick, and the surrounding soil is about 70 cm thick and is smooth and smooth. Drain the trenches around the pits to prevent rainwater intrusion. After cellaring, the feed fermentation is softened and sinks, and it is easy to collapse soil cracks around the cellar mouth. Regardless of whether there are cracks, tamping the pit around the corner every day, and then add soil pressure, in order to prevent leakage, intake. 30 to 45 days of silage, that is, the completion of the fermentation process, open cellar can be used. When taking the material, use as much as you like, and cover it with straws and other things at any time after taking the material.
Bagged silage. Production of plastic bags: Select a double polyethylene film with a thickness of 0.08 to 0.1 mm and a width of 80 to 100 cm. Cut and grow 160 to 170 cm. Heat and flatten the film joint with an iron or iron. Each kilogram of plastic film can be made into 4 to 6 bags, each bag can hold 100 kilograms of potato vines; Silage: Using silage method of crypts, the processed mango vines are bagged, while pressing and pressing the side, try to compact, reduce the bag inside Residual air. Do not use excessive force when pressing so as not to break the bag. After the bag is full, it is tightly sealed and stored in a cool house. After 20 days, it can be used. Follow with the feed, take the bag immediately after taking it.
Freeze-dried powder is a sterile powder injection obtained by freezing the liquid medicine into a solid state in a sterile environment, and subliming and drying the water in a vacuum. Freeze-dried powder is composed of a bottle of high-purity and high-active biological protein freeze-dried powder and a high-purity liquid essence. When using, it needs to be connected with a patented vacuum to reconstitute the freeze-dried powder and the essence to activate the biological protein activity.
