#Nineteenth Agricultural Fair #Whether it is a rural flower planting professional household or a family flower, it is too common to spray potassium dihydrogen phosphate. However, whenever it comes to specific operations, there will always be more or less, potassium dihydrogen phosphate has different degrees of harm to flowers, and it is very difficult to overcome. What is the cause of this?
In layman's terms, it is the effect of the excessive concentration of the formulated potassium dihydrogen phosphate solution. Especially for family flowers, the amount of potassium dihydrogen phosphate used is very small, and there is no suitable one that can weigh a small amount of potassium dihydrogen phosphate, so it is easy to have a large concentration of the prepared solution and harmful flowers.
Here to the family flower friends, introduce some very simple preparation of potassium dihydrogen phosphate solution concentration of small methods and tips. Generally, family flowers, whether it is foliar spraying potassium dihydrogen phosphate, or irrigation roots, the concentration of 0.1%, that is, the ratio of 1:1000, is no matter what the flower, is very safe, the concentration is neither high nor low.
So, at home, there is no balance and scale to weigh the 1 gram of 2 grams of micro-potassium dihydrogen phosphate? There is a very good way here, that is, to buy a salt spoon commonly used in the family, which is very standard. Because of the edible salt spoon, each scoop is basically 1 gram of table salt. The density of edible salt and potassium dihydrogen phosphate is basically the same, which can be regarded as the density of these two substances as heavy. Therefore, when using potassium dihydrogen phosphate, it is possible to use a salt spoon to measure the weight of potassium dihydrogen phosphate.
Then, in general, the water in the family does not have a weighing instrument to weigh the weight of the water. Here we can use a 500 ml mineral water bottle to measure the weight of water, because the density of water is 1 ml / g, 500 ml is equal to 500 g, 1000 g of water requires two bottles of mineral water.
Therefore, when a household prepares a 1:1000 ratio of potassium dihydrogen phosphate, you can take a spoonful of potassium dihydrogen phosphate, take 2 bottles of mineral water capacity, dilute evenly, it is a 0.1% concentration of potassium dihydrogen phosphate solution.
Such potassium dihydrogen phosphate solution, whether it is watering, spraying flowers or irrigating roots, is very safe and reliable, and after use, there will be no negative effects.
In practice, if potassium dihydrogen phosphate is used for root irrigation, the concentration of potassium dihydrogen phosphate can be increased to 0.2%, and the ratio is 1:500, which has no effect on any flower. In general, such a concentration of potassium dihydrogen phosphate irrigation, flowering or spraying, it is recommended that once a week is enough, do not apply more. If the concentration is lower than 0.1%, it can be once a day, or once every two or three days. These methods are summed up in my long-term flower raising process.
