First, the modulation and storage of green hay.
After the pasture is harvested, it can be spread in the field. When the water is reduced to 30%, it can be piled up into a small pile about one meter high and allowed to air dry. In rainy or rainy seasons, it is best to pile the grass into a conical or ridge shape, keep it fluffy, and leave a ventilation duct in the pile for l weeks to 3 weeks.
The dried hay should be stored reasonably. It is best to use a scaffold for stacking or stacking in the open air. Pay attention to the damp-proof bottom pad when scaffolding, and be careful to make the middle high and low in the open air.
Second, silage technology.
Silage is a technique that uses the growth of microorganisms to preserve high-quality artificial pastures, which can maximize the preservation of nutrients in pasture. Silage methods include silos, silos, bags and bales of silage. Commonly used are silage (cement) and bagged silage.
窖 silage: silage 窖 is round or rectangular, the walls and bottom of the raft are cemented, smooth and flat, and the bottom should be drained.
Bagged silage: The general bag is made of a 0.2 mm thick non-toxic plastic film. There are medium and small bags. Medium-sized bags are generally rectangular, 4 meters long, 2 meters wide and 1.5 meters high. The small bag is generally cylindrical, 1 meter high and 1.1 meters in diameter, and can be moved at will. When the bagged silage is used, the silage materials such as pasture are dried, and the water content is controlled at 60%-80% into 2 cm to 6 cm (4 cm to 6 cm for ryegrass and 2 cm to 3 cm for corn stalks). When packing, it should be squeezed tightly layer by layer. After filling, seal tightly, tightly and not ventilated, but be careful not to overfill it so as not to puncture the pocket.
Pay attention to the following matters when silage:
(1) Timely castration: Gramineous grasses are suitable for heading period and legume forages. (2) Washing sputum and bag: Fumigation with sulphur or formalin before silage and drying the water. (3) Short-cut raw materials: Silage raw materials should be cut short, which is easy to compact and exclude air, which is beneficial to the intake of sugar by lactic acid bacteria. (4) Quick loading: It should be carried out on sunny days. Filling should be fast. Filling should be done layer by layer. Each layer should be 15 cm~20 cm. Immediately, the four corners and the backing should pay attention to the tightness. (5) Repression capping: After the silage is filled, first seal it with plastic cloth, then seal it with hay or wet soil to prevent leakage.
After the silage has been stored for 40 days to 50 days, it can be used in the kiln (bag). Good quality silage feed is yellow-green, with a strong acid or distiller's taste; medium-quality yellow-brown, slightly wine and aroma; inferior quality black or brown. Medium quality silage is barely available, but cannot be used for pregnant animals.
