1. Absorb application efficiency
Potassium phosphite can be transported in multiple directions through leaves, roots, xylem and phloem, and its absorption rate is 5 times faster than that of phosphorous phosphate. It has a strong root promoting effect and promotes plant robustness and effective control of the top edge.
It can meet the timely supply of nutrients at the top of the fruiting period of the fruit tree, can avoid excessive nutrient growth of the plant, make the crop full of flower buds, more flowers and more fruits, improve fruit setting rate and fruit quality. The effect of using it on a variety of crops is much higher than that of potassium dihydrogen phosphate, which is three times that of potassium dihydrogen phosphate.
Second, disease resistance
After potassium phosphite is applied to crops, it can be absorbed by plant leaves and roots and transported to the plant to exert its direct sterilization function. At the same time, it starts the disease resistance defense system. When the pathogenic bacteria invade the plant, the plant is stimulated to produce plant defensins to produce disease resistance ability.
When the pathogenic bacteria invade, the pathogenic bacteria can be attacked by potassium phosphite, so that the pathogenic bacteria are partially controlled. At this time, the pathogenic bacteria are also recognized by the plant cells, so that the potassium phosphite starts the defense system to produce plant defensins and PR proteins.
Directly attack the pathogenic bacteria, and will issue a warning call to other cells that have not been attacked to activate the defense system, and then add additional proteins to the polysaccharides to strengthen the cell wall, so that the pathogenic bacteria will be suppressed or killed by the plant's reaction.
In addition, potassium phosphite has a miracle effect in the prevention and treatment of ulcer disease, especially when it is used in the adversity of crops. After being mixed with other fungicides and copper preparations, it has a special effect on the prevention and treatment of ulcer disease in the rainy and rainy weather in the south.
Three, systemic conduction
Potassium phosphite has a systemic up-and-down conduction effect, activates crops to produce polyphenols and reactive oxygen molecules, and stimulates the activity of defense enzymes. It has eradication and prevention functions against crop diseases. Regular use can greatly improve crop resistance and stress. Disease resistance, improve the longer pathological changes of crops, and improve the vitality of crops.
4. Release the solidified elements in the soil
Potassium phosphite used in the roots (irrigation, drip irrigation, showering, rushing) can release the fixed calcium, zinc, iron and other elements in the soil, loosen the soil, increase permeability, improve the rhizosphere environment, the healthy development of crop roots, plants robust.
5. High security and mixing
Potassium phosphite can be mixed with a variety of copper preparations without phytotoxicity, and can also be mixed with a variety of pesticides, fertilizers, etc., but can not be used with strong alkali preparations. Potassium phosphite can be freely mixed with common medium and trace element fertilizers (calcium alkoxide, chelated calcium, etc.). Potassium phosphite can accelerate the ripening of new shoots. The fruit produces phytotoxicity. Six, the product's multiple efficacy characteristics:
1. Leaf spraying, rushing and drip irrigation can absorb quickly, and can quickly add phosphate and potassium fertilizer, with high absorption efficiency.
2. It is not easy to fix in the soil, and at the same time release the solidified iron, zinc, calcium and other elements in the soil, it is easy to be absorbed, and the absorption utilization rate is high.
3. Promote rooting, promote fruit color transformation, increase sugar content, promote flower bud differentiation, and promote photosynthesis.
4. It is not easy to antagonize with trace elements, and the PH value is neutral. It can be mixed with most pesticides, copper preparations and fertilizers.
5. It has the effect of regulating growth, which can control shoots and prosperity in the early stage of crop growth and promote flowering.
6. Anti-disease, improve crop resistance to downy mildew, disease, black spot, Phytophthora, root rot, etc., and have special effects against ulcer disease!
Properties and indicators: The stock solution of this product is a clear, colorless, slightly odorous liquid with a pH of 5-6.5, containing 550 g/L of phosphorus, 300 g/L of potassium, and 2-5 g of TE (chelated boron, zinc) /L, specific gravity 1.46, safe to use, stable performance, long-term storage stability, high nutrients used in agriculture, strong compatibility, no crystallization, good compound type, is a very good sterilization and phosphorus fertilizer.
Product use: This product can make long-acting phosphorus and potassium liquid fertilizers, and can be compounded with calcium, magnesium, zinc, and copper preparations. Adding nitrogen fertilizer can also compound high-concentration compound liquid fertilizers, which has high fertilizer efficiency, easy absorption, and has bactericidal effect. , To achieve multi-functional fertilizer, made of foliar fertilizer, without burning leaves, sterilization and potassium supplement.
In simple terms, potassium phosphite has high safety, can be compounded, has low cost and good effect, which is unmatched by conventional phosphorus and potassium fertilizers. Compared with copper preparations, copper preparations are more susceptible to phytotoxicity. Potassium phosphite can be used safely in both flowering and young fruit periods. Therefore, using potassium phosphite to prevent ulcer disease is a very good choice.
Today, potassium phosphite has been widely used in North America, Brazil, Israel, Southeast Asia, Taiwan and some European countries and regions, and has achieved very good results. Especially in green and pollution-free vegetables, fruits and high-end ornamental cash crops, potassium phosphite is welcomed by the majority of farmers.
