Then, with the development and promotion of fertilization technology, can fertigation completely replace compound fertilizer?
Experts said that traditional compound fertilizers are generally used as base fertilizers, and they are used in large quantities. Generally speaking, crops tend to have excess nutrients in their early stages, but they lack nutrients in later stages and are not conducive to crop growth. Therefore, this method of fertilization is actually unscientific. Although a small amount of multiple top dressings is the best way to add nutrients to crops, the main problem is that the labor cost is too high, and economic crops or greenhouse greenhouses can be used, and field cultivation is not practical. The development of drip irrigation and fertilization technology can make this way possible. Some people even say that if it can ensure adequate top dressing, it is not necessary to apply base fertilizer to crops, and the manufacturing process of flushing and fertilizing is simpler and more cost-effective than compound fertilizers.
At present, red fertilization is widely used in greenhouses and open field vegetable production, mainly in the period of vigorous vegetable growth, such as if the season of vegetable fruits, every picking of fruits and vegetables, cabbage cabbage, etc., have quick results and good results.
However, with the development of controlled-release fertilizer technology, the utilization of compound fertilizer has been greatly improved, and nutrients can be evenly released throughout the crop growth period. Although it cannot be said whether red fertilization can completely replace compound fertilizers, fertigation products are gradually becoming hot words for dealers and farmers, and a large number of fertilizing companies in China are gradually creating their own brands, and fertigation will enter new developments. stage.
