Hay modulation. There are many ways to dry high-quality hay. The simplest method is to naturally dry the harvested pasture either in situ or in a dry, high-dry place 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 broken and shed, and the loss can reach 20%-30% in severe cases. Therefore, we must choose the appropriate harvest time, minimize the turnover and handling, and reduce losses.
Silage preparation. Choose a place where the soil is hard, the ground is high and the groundwater level is low, and the silo is built. Conditions can be used to build a permanent cellar with bricks and cement. Commonly used silage materials include grassy corn, ryegrass, bromegrass, leguminous peony, clover, milk vetch, other rhizomes such as sweet potato, pumpkin, 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, 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 feed is 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 placed 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 should be practical. It has been installed to a height of about 60 cm along the cellar and 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 the drain around 1m away from the pit 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 air leakage.
