Potassium Phosphate Monobasic CAS 7778-77-0

With the in-depth promotion of the “potassium supplementation project” and “soil testing and fertilization” technologies of the Ministry of Agriculture, the demand for KH2PO4 in agriculture has also increased. Potassium is an essential nutrient element for plant growth. KH2PO4 is a high-concentration binary compound fertilizer without chlorine, which can effectively provide P and K nutrients required by plants. Its salt content index is low, and it does not burn the roots of flowers, rice, corn, sweet potatoes, cotton, wheat and other crops. KH2PO4 is an ideal crop fertilizer. It is often applied to rice, corn, wheat, cotton, sweet potato, flowers, etc. by foliar spraying, seed soaking, fertilizer root soaking, seed dressing, basal fertilizer, top dressing, etc. to promote metabolism and increase plant height. , Enhance the photosynthesis of stems and leaves, fruit moss, make the fruit plump, bright color, and have the effects of ripening, cold resistance, drought resistance, wind resistance, and yield increase. KH2PO4 is a one-time dissolving fertilizer, which has the advantages of less dosage, easy absorption, high fertilizer efficiency, and quick effect. KH2PO4 can not only improve soil fertility, but also have anti-cold and drought-resistant effects on plants. Studies have found that KH2PO4 also has certain effects on plant pest control and disease prevention. As a high-efficiency compound fertilizer, potassium dihydrogen phosphate can improve the quality of agricultural products and increase the output by mastering the spraying method and fertilization timing. Taking rice as an example, the application of potassium dihydrogen phosphate at the beginning of the ear can promote the early maturity of rice for 3 to 4 days, the average quality of every 1000 grains of rice can be increased by 1g, and the yield can be increased by 3.80% to 4.55%. Spraying potassium dihydrogen phosphate once in each period can promote the early maturity of rice for 5 to 9 days, the average quality of each 1000 grains can be increased by 1g, the rice seed setting rate can be increased by 0.72% to 1.62%, and the yield can be increased by 6.81% to 9.29%.

The effect of spraying potassium dihydrogen phosphate on wheat growth can not be ignored. Its mechanism of action on wheat can be divided into yield increase effect, quick effect effect, lodging and cold resistance effect, disease and insect pest resistance effect, wind and drought resistance effect, and effect of increasing yield and improving quality. In the north, compared with the previous staged fertilization, the absorption rate of wheat by spraying potassium dihydrogen phosphate is close to 100%. Spraying potassium dihydrogen phosphate during the wheat growth period can provide sufficient nutrient supply for wheat and reduce nutrients between wheat plants. Competition, improve ear setting rate and increase yield. The study found that the absorption rate of wheat sprayed with potassium dihydrogen phosphate is extremely fast, the foliar absorption rate can reach 50% in 1 hour, the absorption is close to saturation in 48 hours, and is converted into energy through photosynthesis, and the absorption is basically completed in 96 hours. It can increase the concentration of wheat plant body fluid, reduce the freezing point of body fluid, thicken plant cells, and enhance internode toughness, so it has the effect of cold resistance and lodging resistance, crops can quickly absorb nutrients, increase plant cell activity, enhance branch function, and ensure sufficient nutrients. A large number of chemical reactions of the plant are carried out, and the immunity and resistance of the plant are enhanced. Spraying potassium dihydrogen phosphate reduces the transpiration of wheat, increases the water content of the leaves, enhances the resistance to hot wind and drought, and increases the chlorophyll content of wheat. Improve the yield and quality of wheat.

According to the US Food Chemical Pharmacopoeia (FCC), the functions of phosphates in the food industry can be divided into 15 categories, namely sour agents, anti-caking agents, antioxidants, buffers, dough improvers, emulsifiers, hardeners, moisturizing agents agent, leavening agent, nutritional agent, preservative, chelating agent, modified starch additive, tissue improving agent, fermented food. Potassium dihydrogen phosphate plays an important role in the food industry, and is usually used as a modifier, fermentation accelerator, nutritional fortifier, flavoring agent, chelating agent, buffer, etc., to improve food quality, as well as preservation and preservation. As an indispensable food nutritional additive, potassium dihydrogen phosphate greatly improves the nutritional value of food, and is of great significance to prevent malnutrition, promote nutritional balance, and improve the quality of life.

In industrial production, potassium dihydrogen phosphate has a wide range of applications. It can be used as a raw material for the production of potassium metaphosphate or other potassium salts, and can also be used as a yeast culture agent, leavening agent, enhancer, fermentation aid, etc. As a strong buffer, it can effectively stabilize the liquid phase in the medium within a certain pH value range, and plays a very good regulating role in electroplating, electrolysis, and salt chemical industries. In the fermentation industry, it is mainly used in the production of monosodium glutamate, wine, alcohol, citric acid, enzyme preparations, yeast, starch and sugar, etc., and is widely used in the biomedical industry. In the field of medicine, potassium dihydrogen phosphate is mainly used as a bacterial culture agent, and is also used in the production of penicillin, oxytetracycline, and inosine. In the feed industry, potassium dihydrogen phosphate is mainly used as a mineral additive for phosphorus and potassium, especially in fish and shrimp feeds. For example, adding potassium dihydrogen phosphate to shrimp feed can improve the survival rate of shrimp and enhance Its disease resistance and body length growth rate can also be greatly improved.
