Colorless Crystal Or White Granular Powder Of Potassium Dihydrogen Phosphate

Potassium dihydrogen phosphate is a chemical with the chemical formula KH2PO4. Deliquescence. It melts into a transparent liquid when heated to 400°C, and solidifies into opaque glassy potassium metaphosphate after cooling. Stable in the air, soluble in water, insoluble in ethanol. Industrially used as a buffer and culture agent; also used as a bacterial culture agent to synthesize clear seasonings, raw materials for potassium metaphosphate, culture agents, enhancers, leavening agents, and fermentation aids for brewing yeast. Used in agriculture as high-efficiency phosphate-potassium compound fertilizer.

There are 4 key points in using potassium dihydrogen phosphate to "urge flowers"

In the process of growing flowers, nitrogen, phosphorus and potassium are the most basic fertilizers, and some phosphorus and potassium fertilizers must be used to promote flower blossoms, such as potassium dihydrogen phosphate or Huaduoduo No. 2.

But in the process of urging flowers, florists will also encounter some phenomena, such as using potassium dihydrogen phosphate many times, but the plants still do not bloom. In fact, there are four points to pay attention to.

Point 1: The concentration of water should be correct

If you are using potassium dihydrogen phosphate, you must pay attention to the concentration. The main reason is that potassium dihydrogen phosphate is a relatively high-purity phosphorus potassium fertilizer, so you must use it according to the instructions.

Generally, potassium dihydrogen phosphate should be made into 1000-fold aqueous solution, that is, one gram of potassium dihydrogen phosphate is added to 1000 ml of water to fully dissolve it, and then watered into flower pots or sprayed on the leaves of plants. This concentration is the safest.

Point 2: Pay attention to the frequency of use and supplement other fertilizers

Many flower lovers know that potassium dihydrogen phosphate can urge flowers when growing flowers, so when the plants develop flower buds, they continue to use fertilizers. However, due to the high frequency of fertilization and only use potassium dihydrogen phosphate, this Will cause planting to not bloom.

In the process of plant growth, in addition to phosphate fertilizer and potassium fertilizer, nitrogen fertilizer is very important, so especially in the spring, summer and autumn, when the plants grow rapidly, it is necessary to sprinkle some three yuan in the flowerpot every 1 to 2 months. Release fertilizers or organic fertilizers, and then regularly supplement phosphorus and potassium fertilizers, so that the nutrition is comprehensive, to achieve the best effect of inducing flowers. Of course, if you find it troublesome, you can directly use Huaduoduo No. 2 to supplement both phosphorus and potassium fertilizers and nitrogen fertilizers. .

Point 3: Can irrigate roots and spray leaves

When using fertilizers, everyone should be careful not to water the pots blindly. In fact, for some plants, spraying on the leaves will have a better effect, such as maintaining hydrangea, rose, and bougainvillea.

When watering each time, water the pots with phosphorus and potassium fertilizers, and spray them on the leaves of the plants. This will help the top flower buds quickly absorb nutrients and accelerate flowering.

Point 4: Use in the reproductive growth period of flowers

Everyone should also understand the most basic growth cycle. The process of plant development, flowering, and fruiting is called the reproductive growth period. Phosphorus and potassium fertilizers are used in the reproductive growth period, and the effect of using it in the vegetative growth period is not great.

For example, in the conservation of roses, after March each year, the plants have gradually started to develop flower buds at the top of the branches. Therefore, starting from March, the roses will be watered and sprayed with phosphorus and potassium fertilizers every 2 to 3 weeks, until the flowers bloom, stop using fertilizers.

Therefore, when growing flowers, if you want to grow flowers, you must be careful and patient. Follow the instructions to use some fertilizers and drugs, so that you can achieve better results.
