Potassium dihydrogen phosphate is a high-quality foliar fertilizer, which widely used in citrus, rice and other crops. Many customers ask us how to mix it to make it work well. The following Rena will give you a specific analysis.
1. Potassium dihydrogen phosphate+urea
It can promote the color change and sweetness of fruits. In addition, it can promote grain fullness, and urea is a fertilizer with strong ability to penetrate leaves, which can quickly supplement nitrogen and provide enough nutrition.
It combined with nitrogen can rapidly supplement nitrogen, phosphorus and potassium in vegetables. This is suitable for fruits and vegetables with poor growth, and also suitable for fruit preservation after fruit trees shed flowers. In addition, if the premature senescence of rice and wheat is serious, this formula can be sprayed to recover.
Urea is generally selected from the regular biuret with less content, and it can be selected from the source bank of phosphorus and potassium with purity above 99.7%. In addition, the use concentration of urea is generally 1%(1 gram is mixed with 100 grams of water). P and K source pool should be above 0.2%, and Gramineae crops can choose higher concentration.
2. Potassium dihydrogen phosphate+boron fertilizer
They are generally used to promote flower bud differentiation in autumn and winter. And to preserve flowers and fruits during flowering period of fruit trees in spring. Moreover, this formula has a wide application range, which is practical for large fruits and vegetables.
When preparing boron fertilizer, it is not recommended to use borax with poor solubility. Borax is not suitable to be mixed with it, but can be matched with the boron source bank which can be dissolved in water. The boron source bank belongs to the foliar fertilizer which can be dissolved in cold water. It is generally recommended that the application concentration of P-K source bank be 0.1-0.2%, and that of B source bank be 0.1%.
3. Potassium dihydrogen phosphate+brassinolide
Brassinolide is widely used in crops. It can not only improve the anti-stress ability of crops, but also improve the anti-freezing ability of crops. This formula is widely used, such as anti-freezing in winter or keeping out the cold before the arrival of cold in late spring. We recommend that you spray it 3-7 days before the onset of cold wave. It is recommended that the concentration of P and K source pool be 0.2%, and brassin is generally based on the content.
