Methods of using water-soluble nitrogen, phosphorus, and potassium fertilizers:
Today, the editor will introduce the effects of various nutrients on plants: quick-acting water-soluble fertilizers, how to use them in green plants and flowers, let's learn about them together.
In yesterday's article, it was mentioned that Chinese roses are like "dung baskets" and they love fertilizers very much. What kind of fertilizers can be used for Chinese roses? What different effects do different fertilizers have on the growth and flowering of Chinese roses?
Today, let's first share with you: the use of water-soluble fertilizers in Chinese roses.
What is water-soluble fertilizer?
Simply put, fertilizers that can dissolve in water can be called water-soluble fertilizers.
Commonly used water-soluble fertilizers:
1. Quick-acting compound fertilizer
2. Nitrogen fertilizer
3. Monopotassium phosphate
4. Medium-element water-soluble fertilizer
5. Trace-element water-soluble fertilizer
These are all common water-soluble fertilizers, also known as inorganic fertilizers, commonly referred to as chemical fertilizers. Each type of fertilizer contains different nutrients and has different effects on plant growth.
The role of various nutrients in plant growth:
We often say that nitrogen, phosphorus, and potassium fertilizers are the three major nutrients needed for flower growth. So what exactly do these three fertilizers do for flower growth?
Nitrogen fertilizers mainly provide the nutrients needed for the growth of flower stems and leaves.
Phosphorus fertilizers mainly promote root and flower growth.
Potassium fertilizers help to fill out fruits and strengthen plant growth.
That is to say, during the seedling stage of flowers, the most needed is nitrogen fertilizer, so nitrogen fertilizer can be mainly used during the seedling stage. After flower buds appear, phosphorus and potassium fertilizers can be applied instead.
When fertilizing, remember a mnemonic: Nitrogen for leaves, phosphorus for flowers, potassium for fruits and strong seedlings.
Methods of using water-soluble nitrogen, phosphorus, and potassium fertilizers:
In the entire growth period of Chinese roses, a combination of quick-acting water-soluble fertilizers and long-acting fertilizers is needed to ensure adequate nutrients (G-Y).
Therefore, during the growth period of Chinese roses, a quick-acting water-soluble fertilizer should be applied every 10 days or so.
In the germination stage, quick-acting nitrogen fertilizers or compound fertilizers containing nitrogen, phosphorus, and potassium can be used with watering.
After flower buds appear, switch to phosphorus and potassium fertilizers (monopotassium phosphate or Flower多多 No. 2).
In addition to the three major nutrients mentioned above, Chinese roses also need medium-element fertilizers and trace-element fertilizers.
Talking about this, let's回顾一下. In the previous article about soil mixing for Chinese roses, didn't I say that the soil for Chinese roses should be balanced in nutrients and have fertilizer-retaining properties? It cannot be a single matrix or sandy soil because it can easily lead to a deficiency in trace elements.
So what are medium elements? What are trace elements?
Trace elements are nutrients that plants need in smaller amounts, such as boron and zinc.
Medium elements are nutrients between trace elements and the three major nutrients nitrogen, phosphorus, and potassium.
For example, Chinese roses require relatively more calcium, magnesium, and phosphorus compared to other flowers. In Chinese roses, calcium, magnesium, and phosphorus fertilizers are called medium elements.
Methods of using medium-element fertilizers and trace-element fertilizers:
Trace-element fertilizers are generally used to target补充 when Chinese roses show symptoms of nutrient deficiencies. They are not commonly used.
Medium-element fertilizers play a very important role in the life activities of Chinese roses and should be used preventively. They can be applied regularly. During the growth period of Chinese roses, applying once every 2-3 months is sufficient.
In addition to regularly applying quick-acting water-soluble fertilizers, it is also necessary to apply long-acting fertilizers such as controlled-release fertilizers, slow-release fertilizers, and organic fertilizers.
If long-acting fertilizers are used well, they can ensure that your Chinese roses have green leaves and red flowers. However, if used improperly, they can easily cause irreversible fertilizer damage.
