The true fertilization contains NPK and chelating trace elements, which are essential nutrients for crop growth. However, how to use fertilization is the key. The key to using fertilizer is to use it well.
Quasi-fertilization period
The application of fertilization in the crop growth period is good, for example, in fruit and vegetables, it can be applied in the fruit-bearing period and after picking the fruit. Another example is Chinese cabbage. In the autumn planting, it should be applied during the filling period and when the temperature drops. Other vegetable crops should also be applied during the growing season.
Control irrigation volume
Prevent flooding under flood irrigation. When the canal is filled, the depth of the ditch is appropriate to the amount of water to prevent the nutrients dissolved in the water from being lost with water. Many farmers like to use this method of topdressing. It is effective to use it well. However, in order to pursue the effect of the surface, regardless of the cost, the use of a large amount of nitrogen fertilizer on one side and the abuse of fertilization will lead to a long vegetable, a decline in quality, a decrease in fertilizer utilization rate, a large loss of nitrogen, and an increase in salinization of soil properties.
Some people smashed the granular high-concentration compound fertilizer and rushed it; some people used unfertilized insoluble solid organic fertilizer or microbial preparations as fertilizers, which are not appropriate.
In short, in principle, the following points should be mastered: the method of applying fertilizer should be used in a timely and appropriate manner, mainly for top dressing in intensive vegetable cultivation, mainly with nitrogen and potassium. Secondly, there are four types of fertilizers that should not be applied: one does not apply phosphorus; the other does not apply granular compound fertilizer; three does not flush solid organic fertilizer; four does not flush microbial preparations or fertilizer.
