Which flush fertilizers are commonly used for vegetables? What should be noted when applying them? We also ask experienced netizens to help explain.In the process of growing vegetables, using flush fertilizers can quickly and effectively provide nutrients to vegetables, so as to promote vegetables to come to market earlier. Therefore, Zhongdiwang has compiled the commonly used flush fertilizers for vegetables and the precautions, listed below for netizens' reference.
1. Quick-acting chemical fertilizers:
The quick-acting chemical fertilizers commonly used for vegetables include urea, ammonium nitrate, potassium nitrate, potassium dihydrogen phosphate, potassium sulfate, potassium chloride, etc. This type of fertilizer is relatively highly water-soluble, and generally it can be directly dissolved into water when watering.
2. Compound fertilizers:
The compound fertilizers commonly used for vegetables mainly include diammonium phosphate, chlorine-phosphorus-potassium compound fertilizer, ammonium-phosphorus-potassium compound fertilizer, etc. This type of fertilizer is relatively poor in water solubility, and after application there is often more fertilizer residue left on the ground. Generally, it is required to soak the fertilizer in water 2-3 days before application, so that the effective components in the fertilizer fully dissolve into the water. When applying, take the supernatant and pour it into the field along with the water.
3. Organic fertilizers:
The organic fertilizers commonly used for vegetable flush fertilization mainly include human manure and urine, pig urine, as well as chicken manure and cake fertilizer with relatively high quick-acting component content. When flushing fertilizer, first fully soak and ferment the organic fertilizer 10-15 days in advance, and when watering, take the supernatant and flush it into the field along with the water. The ammonia in organic fertilizers volatilizes easily, causing "ammonia poisoning" in vegetables. Therefore, when flushing fertilizer in protected areas, the concentration of the fertilizer solution should not be too high; light color and weak smell are suitable.
