How to choose the appropriate mix and mix combination in pasture mixed planting is a more complicated problem. When selecting the mixed pasture, the species and variety that are most suitable for the local soil and climatic conditions should be selected, and according to the purpose of use, the period of use, and selection 2 - 3 or 4 - 5 species of pasture are mixed. In general, mixed pastures are composed of two major categories: grasses and legumes. In the field rotation of the field, in order to restore soil fertility, forage grass is produced, and the mixed forage grass is usually used for 2 to 3 years, and the used grassy grasses and legumes are often used. In the feed rotation, the forage is mainly used, and the utilization period is 4-7 years, and the mixed propagation of the grasses and legumes is used. The grazing-based artificial grassland includes the upper legume forage, the lower legume forage, the upper sparse cluster and the rhizome grass and the undergrass forage, while the following grasses and legumes are the main .
Choose a suitable blended forage combination to provide sufficient forage for the stable development of livestock production.
A samarium–cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. Smco is also named with Smco magnetic steel, Smco permanent magnet, Smco permanent magnetic iron and rare-earth cobalt permanent magnet.
It's a kind of material made from raw earth metal samarium and cobalt and produced by after a serial of process burdening, melting, milling, pressing and sintering.It's also a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior than NdFdB magnetic material. It needn't to be coated because it is difficult to be eroded and oxidized.
Sintered Smco permanent magnetic materials have the character of brittleness, lacking of the ductility. So it isn't suitable for using as structural part when being designed. The physical specifications of Smco(1:5) is better than Smco(2:17)'s because Smco(1:5) is easy to machine while Smco(2:17) is more brittle. Smco permanent magnet magnetized must be picked up carefully during the process of assembling.
Smco Magnet is widely used in space probe, national defense and military, microwave appliance, communication, medical equipments, motors,instruments, various magnetism spreading devices, sensors, magnetic processor, magnetic lifter and so on.
