5. Weak alkaline fertilizer: PH4.2-4.8.
Application of water-soluble fertilizer ammonium dihydrogen phosphate:
1. The main function of water-soluble ammonium dihydrogen phosphate is to promote the root growth of plants and improve the quality and yield of fruits.
2. Water-soluble ammonium dihydrogen phosphate can not only be used for flower top dressing, but also suitable for various soil types, it contains nitrogen, phosphorus and other nutrients required for flower growth, of which nitrogen is an essential nutrient element for plants in the growth stage, which can promote the growth of plant foliage.
3. The phosphorus element in water-soluble ammonium dihydrogen phosphate can participate in photosynthesis, respiration and other processes in plants, and can also promote the formation and growth of plant roots, in addition to improving the adaptability of plants to the external environment.
Applicable crops:
Vegetable crops: tomatoes, eggplants, cucumbers, loofahs, bitter melons, bell peppers, beans, beans, cabbage, cabbage, lettuce, lettuce, green onions, garlic, leeks.
Fruit crops: loquats, peaches, grapes, watermelons, cantaloupe, melons, apples, citrus, pears, bananas, mangoes.
Food crops: wheat, rice, maize, potatoes, sorghum, soybeans.
Other crops: cotton, tobacco, tea
Application compatibility
Ammonium dihydrogen phosphate is usually mixed with other water-soluble nitrogen fertilizers (urea, ammonium nitrate) and potassium fertilizers (potassium nitrate) to provide balanced nutrition for crops; It can be mixed with neutral acidic pesticides, but cannot be mixed with strong alkaline pesticides. Do not mix with fertilizers containing calcium or magnesium to avoid precipitation; Due to the complexity of crop nutrient deficiency and fertility tolerance, as well as the different soil structure and fertility in different places, the specific amount of use should be recommended by local agricultural technicians.
Fertilization matters
Ammonium dihydrogen phosphate has a low nitrogen-to-phosphorus ratio, so it is suitable for all crops and their seedling growth stages, promoting rooting and strong seedlings. It can also be mixed with urea, potassium nitrate, potassium sulfate and other water-soluble fertilizers to meet the nutritional needs of more plants in each growth period. The solution is weakly acidic, which is convenient for flushing, spraying and drip fertilization.
As a fertilizer, it is suitable to apply ammonium dihydrogen phosphate during crop growth, it is better than calcium and ammonium sulfate in acidic soils, and it is also superior to other fertilizers in alkaline soils; Do not mix with alkaline fertilizer to avoid reducing fertilizer efficiency. If lime is used in acidic soil in the south, ammonium dihydrogen phosphate should be applied after a few days.
Due to the high phosphorus content of the product and the rapid absorption of water-soluble phosphorus, it can enhance the root development of seedlings and have a fast effect on the initial growth of crops.
Since phosphorus can improve the differentiation activity of plant flower buds, increase fruit hardness and shelf life, so the product can also be used in the pre-flower stage of crops and fruit forming period.
Other growth stages: It can be mixed with urea, potassium nitrate, potassium sulfate and other water-soluble fertilizers to meet the nutritional needs of more plants in each growth period.
Use an appropriate amount of product with water spray or drip irrigation fertilizer, suitable for the use of base fertilizer and top dressing in arid and rainless areas.
