Can potassium dihydrogen phosphate be homemade? Self-made method and skill of potassium dihydrogen phosphate
According to Xiaobian, potassium dihydrogen phosphate is a commonly used crop fertilizer, which has a great effect on crop growth. Since it is certainly a lot of expenses, then the method of making potassium dihydrogen phosphate is to learn? The following small series will be introduced in detail to everyone. Potassium dihydrogen phosphate should be no stranger to our farmers. Whether it is planted with food crops, cash crops, fruit crops or flower bonsai, it can be used in a wide range of applications. It can not only be used for soaking seeds, seed dressing, but also foliar spray fertilizer, root-filling fertilizer, can be used to promote seedlings, promote flowers, promote fruit, but also improve quality and increase yield, the effect is also a lever drop, simply It is a universal artifact! Although the price of potassium dihydrogen phosphate is not cheap, it does have a very good effect on crops, and most farmers will buy it directly. In fact, many people do not know: with calcium phosphate, ash and water, you can also easily produce high-potency potassium dihydrogen phosphate solution! The production method is described in detail later in the article. Let us first talk about the scope of application of this versatile potassium dihydrogen phosphate on crops, the optimal application period of different crops, and the manner and concentration of use on different crops. 1. Applicable crop types of potassium dihydrogen phosphate Suitable for most grass crops, legumes, cash crops, vegetable crops and fruit trees such as citrus, watermelon, apple, pear, grape, hawthorn, banana, mango, lychee, longan, jujube, kiwi, strawberry, rice, Wheat, corn, cotton, soybeans, peanuts, loofah, tomatoes, beans, eggplant, pepper, spinach, leeks, potatoes, edible fungi, herbs, flowers, lawns, tea, tobacco, etc. Second, the use of potassium dihydrogen phosphate on different crops, concentration and best use period Third, the use of potassium dihydrogen phosphate note: 1. The concentration used in the above table is the applicable concentration range of the crop. When used, the concentration can be appropriately reduced according to the actual situation of the crop, and the purity and chlorine content of potassium dihydrogen phosphate can be checked. If the concentration is not accurately determined, the concentration can be safe. For use below 300, the use of potassium dihydrogen phosphate at an excessive concentration will cause fat damage. 2, should avoid the use of high temperature at noon, can be used before 10 o'clock in the morning or after 16 o'clock in the afternoon, do not use high concentration of potassium dihydrogen phosphate when high temperature. 3, potassium dihydrogen phosphate mixed with acidic or neutral pesticides can increase the efficacy, but mixed with alkaline drugs will occur acid-base neutralization, reduce drug efficacy. 4. Potassium dihydrogen phosphate is a full-water soluble fertilizer. It should be dissolved in water and stored in a cool and dry place to protect it from moisture. 5. At present, the minimum standard for the purity of agricultural potassium dihydrogen phosphate is 92%, and the minimum standard for the purity of first-class products is 98%. In other words, don't buy cheap potassium dihydrogen phosphate with a purity of less than 92%. The secondary or fake goods will not only have no effect, but also cause losses. Fourth, the method of making potassium dihydrogen phosphate solution According to the dosage of 30 kg of water (general sprayer 15 liters of water is about 30 kg) + 6 kg of ash ash + 2 kg of calcium phosphate, put it in the container and mix it evenly, then let it stand for a period of time to prepare potassium dihydrogen phosphate solution; At the time, the use concentration is determined according to the type of the crop to be applied, and 100-300 kg of water can be added according to the concentration. Potassium dihydrogen phosphate is a good helper for the growth of crops. It has a wide range of uses and is conducive to the growth of crops. The above is its method of use and self-made techniques.
