Matters needing attention in applying slow-release fertilizer to greenhouse flowers

In fact, the methods of cultivating flowers in greenhouse and nursery are not the same, especially the method of fertilization, if reasonable fertilization for greenhouse flowers, it can help flowers grow better. The editor will introduce you how to apply slow-release fertilizer to greenhouse flowers.

Greenhouse flowers

1. The temperature of the soil layer at the root of the plant is the driving force for the release of slow-release fertilizer. The release rate of nutrients from slow-release fertilizer will accelerate with the increase of temperature. therefore, it is very important to select the appropriate type and proportion of slow-release fertilizer. Experts suggest that slow-release fertilizer products with uniform, complete appearance and good coating can be purchased.

2. Don't trust the instructions on the bag. Because the instructions on the bags are mostly for container seedlings, such as dosage, etc., but for greenhouse varieties, the actual fertilization ratio is much lower than the values listed in the instructions.

3. If the slow-release fertilizer is mixed with the cultivation medium, it should be used within 2 to 4 weeks. Practice has proved that once the slow-release fertilizer is mixed with the soil, the nutrients begin to be released, and the rapid absorption of the cultivation medium ensures that the soluble salt is not easily produced in the mixture, which is helpful for crops to thoroughly absorb the nutrients of the slow-release fertilizer.

4. The nutritional status of the cultivation medium mixed with slow-release fertilizer is generally difficult to grasp. Even if the fertilization is appropriate, the EC value of the root zone of slow-release fertilizer plants is lower than that of water-soluble fertilizer. Therefore, when the slow-release fertilizer is fully applied, the crops should be timely and necessary to observe and monitor in order to grasp the growth of plants.
