1. Select ranch. In autumn, shepherds should choose mountainside pastures or Pingchuan mountainous areas where the terrain is high and winter is unavailable. In late autumn, the air turns cold and it is necessary to graze as much as possible in the grassy gully so that the sheep will walk less and eat more grass.
2. Grazing time. When frost-free, it is appropriate to leave early and return late, try to extend the grazing time, and if necessary, implement night grazing. After early frost falls in the late autumn, to prevent sheep from eating frost grass, it is appropriate to leave late and return later.
3. Flock management. Sheep tend to grow up in the fall and are active and must strengthen management. When crossing the gates, you must block the sheep to prevent overcrowding; do not allow the sheep to cross the ditch and run when grazing; prevent cripples or miscarriage of the ewes; enter the ranch, it is best to put in the first place to eat the first day, and then put new ground. In pods grazing, the time should not be too long, to prevent excessive swelling caused by eating beans; sorghum, corn and other renewable seedlings toxic, is strictly prohibited in the post-harvest sorghum, corn field regeneration seedlings, but can not harvest this Seedlings to feed sheep; do not drink water in the sump, and do not squat in the wet, muddy place to avoid infection with parasites.
At present, the heat metering market commonly used heat table is divided into mechanical heat meter(mechanical energy meter) and ultrasonic heat meter(ultrasonic energy meter).Heat energy meter is suitable for measuring the heat exchange, known as the heat transfer fluid or liquid absorbing thermal energy conversion equipment, which consists of a flow sensor, temperature sensor and heat calculator three parts. Heat energy meter (thermal meter), also known as Heat Meters, heat energy calculator, both measure heating system for heat and also measure heat absorption cooling system.
Heat energy meter (heat meter) is used to measure and display the water flow through the heat exchange system release or absorb heat. Heat energy meter, is also known as energy meters. The heat energy meters are installed at the inlet pipe or outlet pipe to measure accurate metering and intelligent control of charges of the heat consumption. Its working principle is to install heat energy meters in the heat exchange system, when water flows through the system, according to the supply and return water flow temperature, from the data from the flow sensors and temperature sensor as well as the water flow time, the heat energy meter will calculate the released and absorbed energy through the calculator.
