Green onions should not be ditched to apply fertilizer

For a long time, many vegetable farmers have been accustomed to ditching for one-time topdressing of green onions. This is unscientific because it is not only easy to cut off the roots of green onions, but also burns the young roots of green onions due to excessive concentration of fertilization, leading to dry tips. And the occurrence of dead leaves.
The correct method of fertilization is: in accordance with the principle of “eat less and eat more meals”, from the planting of green onions to harvesting 3 to 4 times, to prevent de-fertilization in the late growth stage of green onions. Every time the top dressing is applied, the fertilizer should be evenly spread on the surface of the root of the green onion, and then the soil is covered with fertilizer to reduce the volatilization loss of the fertilizer, promote the whitening softening and elongation, and enhance the wind resistance. Water is poured once within 2 days after fertilization, so that the fertilizer is quickly decomposed and the green onion is promoted to grow vigorously.

Machine Tapered Bearings

Bearings play a vital role in the machinery industry. Here are a few of the main roles of bearings in the machinery industry:

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.
