What is the function of potassium dihydrogen phosphate when watering flowers
If you want to understand the topic of how potassium dihydrogen phosphate works when watering flowers, the specific introduction is as follows:
What is the function of potassium dihydrogen phosphate when watering flowers
During the flower bud differentiation stage of orchids, a 0.1% to 0.2% aqueous solution of potassium dihydrogen phosphate should be used,喷施 once a week, and 2-3 times a month is recommended. This can effectively promote the differentiation and formation of orchid flower buds; the soil should be loosened the day before fertilizing, and the next morning after fertilizing, water with clear water once; the phosphorus and potassium fertilizer solution for root application is suitable for root fertilization in late spring and early summer, from May to June, and it is not recommended to apply root fertilizer after the autumn equinox.
Using potassium dihydrogen phosphate to water flowers
In fact, potassium dihydrogen phosphate is a high-efficiency phosphorus and potassium fertilizer, mainly used to supplement the phosphorus and potassium elements in flowering plants. It has the advantages of a small amount of use, quick effect, significant fertilizer effect, and the ability to promote flower bud differentiation and plant growth, enhancing the resistance of orchids and other flowers.
It is generally used for foliar application as a root exterior fertilizer and can also be used for root irrigation. However, long-term use of chemical fertilizers alone to water flowers can easily cause the potting soil to become compacted and should be used in combination with organic fertilizers.
Main functions of potassium dihydrogen phosphate
Firstly, it promotes the differentiation of plant flower buds and helps the flower buds grow stronger and plumper.
The phosphorus element promotes the differentiation and formation of flower buds and makes the fruit sweeter, while potassium fertilizer promotes the enlargement of flower buds, mainly used in the early stage of flower bud differentiation and budding of flowering plants. Fertilization with potassium dihydrogen phosphate should be stopped when the flower buds bloom.
In addition, providing enough phosphorus and potassium fertilizers for flowering plants like orchids can result in more flower buds and earlier blooming, brighter flower colors, and a more fragrant scent.
During the flower bud differentiation stage of orchids, a 0.1% to 0.2% aqueous solution of potassium dihydrogen phosphate should be used,喷施 once a week, and 2-3 times a month is recommended.
It can effectively promote the differentiation and formation of orchid flower buds; the soil should be loosened the day before fertilizing, and the next morning after fertilizing, water with clear water once; the phosphorus and potassium fertilizer solution for root application is suitable for root fertilization in late spring and early summer, from May to June, and it is not recommended to apply root fertilizer after the autumn equinox.
Flower friends should be reminded that when喷施ing potassium dihydrogen phosphate foliar fertilizer on orchids and other flowers, avoid doing so in low temperatures and preferably spray in the evening on sunny days.
There are more stomata on the back of the leaves than on the front, so more spray should be applied to the back of the leaves to avoid spraying a large amount of fertilizer solution into the leaf center to prevent fertilizer burn from accumulated fertilizer solution.
Also, the concentration of the liquid fertilizer should be kept within a low range; fertilization with liquid fertilizer for orchids should be stopped before the flower buds open and show color, and phosphorus and potassium fertilizers should not be applied continuously; avoid fertilizing in the evening during rainy or cloudy days.
Details of using potassium dihydrogen phosphate
When using potassium dihydrogen phosphate for flowers, there are some details that need to be paid attention to.
① Pay attention to concentration and intervalThe concentration of potassium dihydrogen phosphate solution can be slightly higher or lower, but it should not be too high.
If the concentration is too high, for example, if we only need a 1000-fold solution but we dilute it to 500-fold or 600-fold, it can be a burden on the flowers and easily cause root burn or seedling burn.
If too much water is added during dilution, resulting in a too-low concentration, it will not achieve the purpose of fertilizing the flowers, and plant growth will become very slow.
The interval between applications should also be noted. For slow-growing plants like longevity flowers or orchids, the interval can be controlled at half a month or even a month; for fast-growing, flowering, and high-yielding herbaceous plants, we can use it every three to five days.
② Mix well and let it sit for a while before useAlthough potassium dihydrogen phosphate is soluble in water, it does not dissolve completely in water immediately after being added to water. It requires a process, so after mixing potassium dihydrogen phosphate with water, it should be let sit for a while before use.
③ Root irrigation and foliar sprayingThe potassium dihydrogen phosphate solution can be used for root irrigation or foliar spraying, or both can be done simultaneously.
When using potassium dihydrogen phosphate solution for root irrigation, it should be done when the potting soil is completely dry for better results, and when using the solution for foliar spraying, it is necessary to spray both the front and back of the leaves. If only the front is sprayed, the effect will only be half.
④ Do not use potassium dihydrogen phosphate as fertilizer for a long timeSince potassium dihydrogen phosphate mainly contains phosphorus and potassium elements, it should not be used alone as a fertilizer for a long time, as it can lead to a deficiency of other elements in the soil, causing poor plant growth.
The best way to use it is to apply potassium dihydrogen phosphate during the plant's budding stage and immediately after the plant has finished flowering, use a balanced compound fertilizer or other fertilizers containing a variety of elements.
