There are many drying methods for hay to modulate quality hay. The simplest method is natural drying. The harvested pasture should be dried in place or transported to a place with high dryness, or on a shelf for drying. Transition to a scaled, mechanized drying method when conditions allow. No matter what kind of modulation method is used, human or mechanical nutrition losses should be minimized. For example, in a series of manual and mechanical operations such as harvesting, handling, air-drying, stacking, and the like, the twigs and leaves are inevitably shredded and shed, and the loss can be as large as 20% to 30%. Therefore, we must choose suitable harvest time for pastures, minimize turnover and handling, and reduce losses. Second, the preparation of silage choice of hard soil, high dry terrain, low groundwater level, built silo. Conditions can be used to build a permanent cellar with bricks and cement. Commonly used silage materials include grassy corn, ryegrass, awnless bromegrass, pods of leguminous plants, clover, and milk vetch, and other roots and stems of sweet potatoes, pumpkins, leeks, and aquatic plants. Raw materials must be harvested in due course. Prematurely, the raw material contains more water and less digestible nutrients; too late, then the vitamin content increases, palatability is poor, and digestibility is reduced. The harvesting period of corn is generally from the milk ripening stage to the wax ripening stage; the gramineous pasture is the booting stage to the heading stage; the leguminous pasture is the budding stage to the early flowering stage; the aquatic feeds are harvested from the sun for 1 to 2 days, and the raw materials must be properly filled. After harvesting, the water is suitable and it should be transported to the silo immediately and cut into short sides. Before the cellar is placed, 10-15 cm thick straw is laid on the bottom to absorb the juice. The four walls of the cellar are covered with plastic film, which can prevent water leakage and permeability. When installed, it must be practical, and it has been installed to a height of about 60 cm along the cellar, and it can be capped. When the roof is capped, firstly lay a layer of chopped straw, add a layer of plastic film, and then cover the soil. Ditch ditches at a distance of 1 meter from the kiln to prevent the inflow of rainwater. When there is a crack in the cellar, it is necessary to compact the soil in time to prevent leakage of water leakage.
