Potassium phosphorous acid paste manufacturer is a new type of phosphate-potassium fertilizer that has appeared in the past two years. Many farmers are still unfamiliar with it. Compared with potassium dihydrogen phosphate, which has been mature for ten years, it can be said that many farmers are already familiar with it. It is a commonly used product and I am very familiar with it. Walk into these two products to understand the differences and usage methods, and further explore the benefits and characteristics of new products for our agriculture, helping farmers increase yields and improve quality.
The main potash fertilizers on the market include potassium nitrate, potassium sulfate, potassium phosphite, dipotassium hydrogen phosphate, potassium dihydrogen phosphate, potassium chloride, etc. What are the characteristics of various potash fertilizers and what are their differences? Only by clarifying their differences can we make better use of them. Here is a brief introduction to the difference between potassium phosphite and potassium dihydrogen phosphate.
The picture shows the potassium dihydrogen phosphate product
1. What are the main characteristics of potassium phosphite
1. It is an environmentally friendly and efficient fertilizer and an important component of the new liquid foliar fertilizer formula.
2. Potassium phosphite has a good inhibitory effect on fungal diseases such as Phytophthora, downy mildew and powdery mildew;
It can also induce crops to produce sustained resistance to pathogenic fungi and viruses. Immunity. In potato cultivation, the application of potassium phosphite has a very good control effect.
3. Potassium phosphite plays an important role in plant disease resistance.
2. What are the main characteristics of potassium dihydrogen phosphite
1. It can be used as a direct bactericide and complexing agent for calcium and magnesium ions in industrial circulating water.
2. Water treatment agent that can replace organophosphines and reduce environmental pollution.
3. Pesticides can be used as intermediates for pesticides, insecticides, and fungicides;
4. It is a highly efficient potassium and phosphorus fertilizer that is pollution-free and non-toxic after use. , no residue, etc.;
5. It can be used as a direct bactericide and complexing agent for calcium and magnesium ions in industrial circulating water, and can replace organic phosphine water treatment agents to reduce environmental pollution.
We all know that potassium dihydrogen phosphate can promote fruit enlargement, preserve flowers and fruits, improve fruit quality, increase coloring, and improve taste. Potassium phosphite can not only achieve the functions of potassium dihydrogen phosphate, but , can also improve the disease prevention and resistance effect of crops, and can improve the immunity of crops themselves.
Is potassium phosphite a fertilizer?
1. There is no doubt that potassium phosphite is a fertilizer, and it is a fertilizer with high phosphorus, high potassium and high utilization rate. 2. Can potassium phosphite sterilize? Potassium phosphite is a fungicide with systemic properties and up-and-down conductivity. 3. Can potassium phosphite be mixed with calcium? Potassium phosphite can be mixed with calcium at will, because all phosphites are water-soluble. So real potassium phosphite can be mixed with calcium. 4. How to judge the quality of potassium phosphite
1. Whether potassium phosphite can be mixed with calcium at will. 2. Put the opening in the air to see if it crystallizes (potassium phosphite that has not gone through a special process is easily oxidized to orthophosphorus by oxygen in the air, losing the sterilizing and disease-fighting effects of phosphorous acid) 3. Mix it with potassium permanganate solution. The faster the color of the potassium permanganate solution becomes lighter, the stronger the reducing power of potassium phosphite and the higher the purity.
The phosphorus in potassium phosphite is trivalent phosphorus, which is very mobile. It can be transported in both directions through xylem and phloem, and its absorption rate is faster than potassium dihydrogen phosphate (phosphate state) 5 Valence phosphorus. It has a good effect in promoting roots, promoting crop fruit expansion and improving quality. At the same time, trivalent phosphorus not only has a good inhibitory effect on fungal diseases such as Phytophthora downy mildew and powdery mildew.
Among the two, potassium phosphite is a preventive and good fungicide in disease prevention and resistance in the immune system, and its potassium phosphate is higher than potassium dihydrogen phosphate, so it is more cost-effective than Potassium dihydrogen phosphate has more functions and characteristics.
In general, potassium phosphite is a “medicated fertilizer” in the true sense
No matter how effective it is, potassium phosphite or potassium dihydrogen phosphate, we must control it safely. within the scope. It is not easy to have too much of a good thing, just like the salt, sugar, etc. that are often eaten in life. You should not overdo it. It will not kill you but you will feel uncomfortable. Why should we spend more money?
Potassium phosphite Some usage issues
Poisoning issues: Some scholars said that continuous use of potassium phosphite may cause premature tree aging, so long-term use is not recommended. From the perspective of the entire growth cycle, the dosage should not be too large during the seedling stage of vegetables before fruiting, and at most twice during the fruiting stage. For apples and peaches in fruit trees, the dosage is 5 times a year, once in the spring flowering period with a ratio of 2,000 times, in the high phosphorus and high potassium period in June with a ratio of 1,200-1,500 times, and twice in the fruit expansion period, with the distance elongated 800-1000 times, 1500 times after picking. Prolonging the growth time of leaves also plays a role in clearing the garden and rapid aging of branches
It is recommended that you pay attention to the concentration when using it, do not reuse it, and try to minimize mixing. For pesticides, choose products from large manufacturers. Avoid using them during high temperatures and droughts. Do not mix them with alkaline pesticides, such as Bordeaux mixture.
Product effects of potassium phosphite
1. Promote the growth of crop roots, make the root system developed and strong, and improve the ability of crops to absorb water and fertilizer.
2. Promote the maturity of spring shoots, inhibit the hairiness of new shoots (summer shoots), and avoid excessive plant growth.
3. Promote the differentiation of flower buds, so that the crop flower buds are full, with more flowers and fruits, and the fruit setting rate is significantly improved.�Safe to use on young fruits.
4. Rapidly expand fruit, promote fruit color change, increase sugar content, ripen earlier, extend fruit shelf life, and significantly improve quality and yield.
5. It has a significant inhibitory effect on fungal diseases such as crop canker, anthracnose, blight, downy mildew and powdery mildew, and can induce continuous immunity of crops to pathogenic fungi and viruses.
6. Use at the roots (irrigation, drip irrigation, root drenching, flushing) can release calcium, zinc, iron and other elements fixed in the soil, loosen the soil, increase permeability, and improve the rhizosphere environment .
