Bearings play a vital role in the machinery industry. Here are a few of the main roles of bearings in the machinery industry: Machine Tapered Bearings,Tapered Roller Bearings,High Precision Hardness Bearing,Low Noise Bearing Hebei Fangqiang bearing manufacturing Co., LTD , https://www.fangqiangbearing.com
The application of available nitrogen fertilizer for delayed seeding of delayed seedlings was sensitive to nitrogen in wheat seedling stage, delayed tillering of delayed wheat seedlings, insufficient individual development, and reduced total number of stems per acre, which directly affected yield. For this type of wheat field, one must grab the smashing and smashing the fertilizer, and apply 8 kg of urea per mu. Second, according to the seedlings, the fertilizer should be applied, 25 kg of ammonium bicarbonate per acre; the third should be sprayed from the heading to the milking stage. Potassium dihydrogen phosphate 1 to 2 times, each time 100-150 grams per acre to increase the weight of 1000.
Control fertilization of wheat fields with good soil fertility and strong growth. Some wheat fields have good soil texture and strong fertilization capacity. In addition, the amount of peach fertilizer applied to the former cotton field is large, and there are many residual fertilizers in the field. The temperature is suitable and the environment is good. The next wheat seedlings are prosperous. If the weather occurs during the heading and filling period, the plants will easily fall. For this type of wheat field, the amount of fertilizer should be controlled.
Differentiate the situation of the seedlings and promote the control reasonably. For wheat fields with weak growth, it is possible to spray Huimanfeng active liquid fertilizer at the right time to promote early tillering, early heading and early maturity of wheat. For the overgrown wheat field, you can use 15% paclobutrazol WP 40-60 g or 5% uniconazole WP 25-30 g per acre, add 40-40 kg of water spray, control the growth and prevent plant lodging. .

1. Support and positioning: Bearings are used to support rotating shafts and wheels so that they can rotate smoothly and ensure that their positions are accurate. Bearings enable machinery to operate efficiently by reducing friction and resistance.
2. Transmit force: Bearings are able to transmit force in mechanical equipment so that it can work properly. For example, crankshaft bearings in automobile engines transmit the power generated by the engine to enable the vehicle to move.
3. Reduced friction and wear: Bearings reduce friction and wear in mechanical equipment by providing lubrication and reducing direct contact between metal surfaces. This not only extends the service life of the mechanical equipment, but also reduces the frequency of maintenance and repairs.
4. Protection against vibration and noise: Bearings reduce vibration and noise in mechanical equipment. By balancing and stabilizing rotating parts, they reduce vibration and noise during the operation of mechanical equipment.
In conclusion, bearings play a vital role in the machinery industry, supporting and positioning rotating components, transmitting force, reducing friction and wear, and preventing vibration and noise. Without bearings, machinery and equipment would not function properly.
In recent years, wheat production in some major cotton-producing areas has changed, mainly in three aspects. First, the sowing period is generally postponed; the second is that some wheat fields are not planted at the time of planting or the base fertilizer is insufficiently applied; the third is that the wheat heading and filling stage often occurs locally or in pieces. In response to these problems, the production method needs to change the fertilization method according to local conditions.
