Analysis and summary of the advantages and disadvantages of water flushing fertilizer
Advantages of flushing fertilizer with water
1. Save labor, time, labor, uniformity, convenience and safety.
2. For vegetables cultivated in ridges, fertilization is concentrated, followed by fertilizer application in alternate rows, which is less harmful to the root system.After fertilization, the fertilizer can go directly to the root of the root along with the water, allowing the root system to absorb quickly.
3. It can avoid the root system damage caused by fertilization by means of furrow or hole digging, and also avoid the phenomenon of concentrated fertilization in local areas, causing root burning, and the harm of tender leaves and stems caused by fertilizer application.
4. It can solve many problems of difficult fertilizer application in cultivation modes, such as small vault, high-density vegetable planting in furrow, planting vegetables covered with mulch, etc.
Analysis and summary of the advantages and disadvantages of water flushing fertilizer
Disadvantages of flushing with water
1. Water solution directly infects the root system of the plant, causing damage to the root system of the plant if there is too much water or solution concentration near the root system.
2. For fertilizers with a slow solubility, such as compound fertilizers and diammonium phosphate, it shall be dissolved in advance to avoid the cavitation and the residue of fertilizer residue after water infiltration, so as to reduce the utilization rate of fertilizers.
3. For some volatile fertilizers, such as urea, ammonium carbon, ammonium sulfate, potassium sulfate, etc., timely ventilation should be carried out after application, otherwise the ammonia concentration is too large, which will easily destroy the plants.
In a word, do not flush fertilizer continuously, and the concentration is not too large, again is not too much water and field water, in case of damage to the root system.
