Rational application of nitrogen fertilizer to eggplant in summer

1, the right amount. Eggplant requires the largest amount of nitrogen fertilizer, but in the hot season, the urea should be controlled within 30 kg per acre. Because of the high temperature season, the conversion rate of urea after applying it to the soil is faster. After the plant meets the needs, the excess will be caused. Loss. Especially in sandy soils, the proportion of loss will be greater. The application rate of ammonium bicarbonate per mu per mu is not more than 40 kg, and the application amount is too large, in addition to causing nutrient loss, it will also cause ammonia damage to eggplant leaves and fruits.

2. Appropriate law. It is a habit for vegetable farmers to apply fertilizers, and it is a habit to use water, but this method should not be used in the summer high season. Because of the higher temperature, when the fertilizer is applied, a large amount of ammonia vapor will reduce the fertilizer efficiency, especially ammonium bicarbonate, which is more likely to cause ammonia poisoning of eggplant. It is best to use ditching or acupoint application. The thickness of the buried soil after top dressing should be no less than 5 cm to reduce the volatilization of the active ingredients of the fertilizer.

3. Reasonable matching. Although eggplant requires the largest amount of nitrogen fertilizer, it is also indispensable for phosphorus and potassium fertilizer. In the case of top dressing, it is not possible to apply nitrogen fertilizer every time. In the fruiting period, it is best to apply 2 times of ternary compound fertilizer, the total of 2 times per mu should be no less than 40 kg to meet the needs of eggplant growth and results.

Super Abrasives


Superabrasives come in the form of grinding wheels and are used when the material being processed is either too hard or too delicate for regular abrasives.

Industrial diamonds are one of the most common materials used to create the grinding material. Contrary to popular belief, diamonds are not as rare as marketing campaigns will tell you.

After diamonds,cubic boron nitride is the second more durable material for cutting. This is followed by polycrystalline.

The most obvious advantage is that these Grinding Wheels are extremely hard and durable. This allows them to give better performance and greater longevity over regular abrasives.

When your wheel lasts longer you will see reduced costs for fixtures and tooling. This opens up your budget up to investing in more machines.

You will notice that the wear and cuts on your materials will be even. Because the abrasiveness of the wheel is so strong, it doesn`t develop uneven worn away spots as quickly as regular abrasive wheels.

So the output from your production will be consistent. So your manufacturing efforts will produce reliable and consistent results.

It can be tough to justify the upfront increased costs of superabrasive wheels. But the durability and quality of their production output make them well worth it.

But you`ll quickly realize that your productivity has increased by using superabrasives. You will have more parts processed per wheel and fewer wheel changes.

Kemei produces both conventional grinding wheel and super abrasive grinding wheels, such as white aluminum grinding wheel, pink wheel ,green silicon wheel, diamond grinding wheel and CBN grinding wheels.
