Can fertilization replace compound fertilizer?

Rushing and fertilizing is also called water-flooding, that is, the solid quick-acting fertilizer is dissolved in water and fertilized by water. From the point of view of fertilizer utilization, the nutrients absorbed by crops mainly depend on the root system, and the root hair area about 1 cm from the root tip is the most active area for absorbing nutrients. Therefore, the application of fertilization is in line with the principle of scientific fertilization. Nutrients can be absorbed by crops through mass flow and diffusion, and can also prevent burning of seedlings caused by dry spreading of fertilizer. From the point of view of fertilization, the application of fertilizer to both the fertilizer and the water is actually the application of water and fertilizer integration technology.

Then, with the development and promotion of fertilization technology, can fertilization completely replace compound fertilizer?

According to experts, traditional compound fertilizers are generally used as base fertilizers and are used in large quantities. Generally speaking, the early stage of crops tends to have excess nutrients, and later there will be insufficient nutrients, which is not conducive to crop growth. Therefore, this method of fertilization is actually unscientific. Although a small amount of topdressing is the best way to supplement nutrients, the main problem at present is that labor costs are too high, economic crops or greenhouse greenhouses can be used, and field cultivation is not practical. The development of drip fertigation technology can make this approach possible. Some even say that if it can ensure adequate topdressing, it is not necessary to apply fertilizer to the crop, and the manufacturing process of fertilization is simpler and cheaper than compound fertilizer.

At present, the application of fertilizer is widely used in the production of greenhouses and open vegetables, mainly in the period of vigorous growth of vegetables, such as the fruiting period of vegetable vegetables, the picking of fruits after each harvest, the cabbage period of Chinese cabbage, etc., with quick effect and good effect.

However, with the development of slow-release fertilizer technology, the utilization rate of compound fertilizer has been greatly improved, and nutrients can be evenly released throughout the crop growth period. Although it is still impossible to say whether the fertilization can completely replace the compound fertilizer, the fertilizer application is gradually becoming a hot word in the mouth of dealers and farmers. A large number of domestic fertilizer companies are gradually creating their own brands, and the application of fertilizer will enter new development. stage.

Oxygen concentrator

When human beings have experienced disasters, we know that life and health are so precious.

When the blue sky becomes gray, we realize that fresh air is so precious. Oxygen is the guarantee
of human survival.
• Benefits of Oxygen:
Inhalation of oxygen can improve the level of arterial blood oxygen partial pressure and oxygen
saturation of the body, in addition to promote the metabolism of the body, and is also one of the very
important methods for auxiliary treatment of a variety of diseases. Oxygen inhalation can make the
oxygen in the human tissue more abundant, cells will get sufficient oxygen supply after the
metabolism will be more active, normal people will have a refreshed, memory improved, spirit feeling.
Patients with chronic heart and lung diseases, long-term oxygen inhalation can delay the aggravation
of the disease, at the same time, but also can relieve the symptoms of chest tightness, wheezing and
dyspnea of patients. Especially when working under great pressure, they are prone to dizziness,

dizziness and restlessness.
