In recent years, rice growers have grown rapidly and rice cultivation has grown in size. In the practice of guidance, I feel that the big players should pay special attention to the following matters:
1. The selection of varieties should be balanced. Large households are easy to achieve scale, especially for high-quality rice orders for agriculture, so the benefits will be better, but to consider the variety growth period, large households will generally be more "double grab" than retail investors, pay attention to staggered labor.
2. Apply more fertilizer to the paddy field. In practice, the paddy field generally shows insufficient fertility, while the tailwater field tends to be over-fertilized. Therefore, when fertilizing, the fertilizer is appropriately applied to the paddy field, and the tailwater field is appropriately reduced.
3, live broadcast is stressful. Live broadcast can save labor and save costs, but pay attention to the selection of the variety when the live broadcast, the amount of seed should be increased, the late rice should also ensure that the safety of the ears, the reclaimed rice should choose the varieties with strong ability to resist and regenerate.
4. The type of herbicide should be suitable. Herbicides should not cause phytotoxicity after being used after re-greening, but it is a tillering period after re-greening. Deep-water is very unfavorable for tillering, so it should be used without flooding.
5. Use agricultural machinery to grab time and increase efficiency. Today, with high labor costs, agricultural machinery is an important measure for large-scale households to seize time and increase efficiency. It is possible to use mechanical farming as much as possible without manpower.
6. Pest control is to prevent and rule. Professional things are done by professionals. The unified defense can reduce the amount of pesticides applied, increase the control effect, and save costs.
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.
