In the farming operation, the most commonly used product is potassium dihydrogen phosphate, but how much do you know about potassium dihydrogen phosphate? Now that the potassium dihydrogen phosphate is flying all over the market, is it true or false? Let the teacher popularize it for everyone! According to the teacher, almost every manufacturer that produces fertilizers sells potassium dihydrogen phosphate. For agricultural stores, almost every store sells potassium dihydrogen phosphate. It is conceivable that the application of the product is extensive. Now! Then come and find out about it! What is potassium dihydrogen phosphate? What is the effect? Planters using potassium dihydrogen phosphate know that it is a binary compound fertilizer with 52% phosphorus and 34% potassium. It is almost completely absorbed by crops and is widely used in almost all types of crops such as various economic crops, food, fruits and vegetables. Mainly by drip irrigation, spraying mainly! The specific effects are as follows: It has many effects such as significantly increasing yield, increasing quality, lodging resistance, resisting pests and diseases, preventing premature aging, etc., and has the effect of overcoming the nutritional deficiencies caused by the decline of root aging absorption ability in the late stage of crop growth. Identification method of potassium dihydrogen phosphate: Everyone knows that all kinds of potassium dihydrogen phosphate in the market are flying all over the sky. The true and false fakes are mixed. I don’t know a little bit of distinguishing skills. The deceived are all our growers. The following teachers summed up two kinds of Identify methods, I hope to be useful to everyone! First, look at the appearance 1. Potassium dihydrogen phosphate belongs to the new concentration of phosphorus and potassium two-element compound fertilizer. There is no other element in the national standard. If you buy the product, there are other elements displayed. Congratulations on buying fake goods. 2, potassium dihydrogen phosphate, the real packaging will be marked with a few Chinese characters of potassium dihydrogen phosphate, marked with detailed manufacturer information, such as labeled "composite type", "improved type", "potassium dihydrogen phosphate type", etc. Information is not the real thing. 3, the real potassium dihydrogen phosphate is white and tasteless crystal color is pure, there is no liquid potassium dihydrogen phosphate product, it does not meet the requirements of the Ministry of Agriculture fertilizer registration, production is not allowed, can be regarded as fake. Second, through the appearance can not be determined to do a few small experiments 1. Use one glass, pour half a cup of warm water, and put some alkaline surface of household. If there are a lot of bubbles, it is the real product. If there is a lot of flocculent precipitation or other reaction, it is a fake and shoddy product. 2, with fire, if there is the taste of ammonia, are fake and shoddy products, because the real product does not contain nitrogen. 3. When zinc sulphate or ferrous sulphate is added to the aqueous solution of potassium dihydrogen phosphate, precipitation will occur. If magnesium sulphate is used, the aqueous solution will not precipitate after adding zinc sulphate or ferrous sulfate. The above is a simple identification method of potassium dihydrogen phosphate. I hope that in the management of farming, we must correctly identify various drugs, so as not to buy fakes to affect the growth of crops! 2 Wire Intercom System,2 Wire Intercom,2 Wire Video Intercom,2 Wire Door Entry System Zhuhai Mingke Electronics Technology Co., Ltd , https://www.mingke-tech.com
