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 use, 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 crops and 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 relevant experts, traditional compound fertilizer is generally used as a base fertilizer, and the amount is large. As a result, the early stage of crops may cause excess nutrients, while the later stage will have insufficient nutrients, which is not conducive to crop growth. Therefore, this method of fertilization is actually unscientific. Although a small number of top dressings are the best way to supplement nutrients to crops, 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 way possible. Some even say that if sufficient topdressing is ensured, it is not necessary to apply base fertilizer to the crop, and the manufacturing process of fertilizing is simpler than the compound fertilizer.
At present, the fertilization is widely used in greenhouses and open vegetables, mainly in the period of vigorous vegetable growth. For example, if the vegetable is in the fruiting period, after picking the fruit, the cabbage period, etc., the effect is fast and the effect is good. .
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 can not be said that 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 a new stage of development. .
