In the early fall season, it is the period of growth of forage grass. During this period, in addition to adequate grazing, farmers and herdsmen can also harvest dry grass and store them for feeding their livestock in winter and spring. In the process of harvesting and drying grass, there are many learning and skills.
The best harvest time for forage is from heading, between the pregnant bud and the flowering period, because during the growth of the pasture, it is the period with the most abundant nutrients and the highest nutritional value, and it is also the peak period of pasture grass production. In addition to timely harvesting, it is also necessary to make the correct method of drying. In the drying process of pasture, it can be divided into two stages: In the first stage, in order to make the pasture plant cells die quickly, stop breathing and reduce the loss of nutrient components, the “thin layered tanning method†should be used to expose 4 hours of exposure. For ~5 hours, the moisture in the grass can quickly evaporate. In the second stage, we must speed up the drying process, stop the activities of enzymes as soon as possible, and try to reduce the destruction of carotenoids due to sunlight exposure. Therefore, we should adopt the "small pile" or "small ridge" drying method and gradually dry. The size of the pile is generally 1 meter high, 1.5 meters in diameter, and about 50 kilograms of grass weight to facilitate continued drying. It can also be quickly dried in the rack or quickly dried in the shed, until the moisture drops to 14% to 17% or less can be stored on the clam.
