Avoid potassium, magnesium and calcium fertilizers fighting each other! Use of dragon fruit element fertilizer

Pitaya is a plant that is covered with green all over the body. All the green parts are photosynthesis. Magnesium is the central atom of the chloroplast. It is the engine of the chloroplast. Use magnesium fertilizer, photosynthesis of stems, priority distribution to the fruit, supplement at the bottom, may encounter the problem of mutual fight of potassium, magnesium and calcium fertilizer.

Magnesium sulfate fertilizer is very cheap, and it can be supplemented with magnesium fertilizer, but the solubility is only 25.1% in 20 degree water and 26.2% in 25 degree water, so it can only be used as base fertilizer, twice in one year, and 75% is used as Insolubles remain in the soil and can exacerbate soil compaction and acidification.

Potassium magnesium sulfate is the same as magnesium sulfate. Therefore, under the premise of using magnesium sulfate or potassium sulfate and magnesium fertilizer, it is necessary to strengthen the leaf spray; if it is more scientific, it is based on the proportion of nutrients taken away by the dragon fruit. , slightly increase the magnesium fertilizer, because the stem is still demanding larger magnesium fertilizer.

Can calcium, magnesium, boron and potassium be sprayed at the same time?

Answer: It is recommended to spray the leaves twice a month, because the products or nutrients produced by the photosynthesis of the stems are preferentially supplied to the fruits. You can make a comparison yourself. If the base fertilizer remains the same, this leaf spray magnesium fertilizer will definitely be fruitful. And stems grow better.
