Detailed usage:
(1) as a base fertilizer
1 Field crops: 10-20 kg of grain crops, 10 kg of urea and 5-8 kg of potassium chloride, 10-15 kg of cotton, and 5-10 kg of urea and potassium chloride;
2 Oil crops: 10-15 kg per mu per year, plus 5-10 kg per urea and potassium chloride;
3 fruit tree crops: adult trees, after picking fruit or early spring germination, 0.5~1.0 kg of diammonium per plant plus 0.5 kg of potassium fertilizer, and 0.25~0.5 kg of urea. Young trees are appropriately reduced in dosage;
4 vegetable crops: 15-20 kg per mu per year, plus 10-15 kg per kg of potash and urea;
5 Combined with high-nitrogen compound fertilizer, the dosage is 5-10 kg.
(2) Topdressing: It should be applied before the crops grow vigorously (such as rice and wheat in the early stage of tillering).
(3) For seed fertilizer: mixed with seeds, the amount of 3-4 kg per mu, generally not more than 5 kg / mu, should avoid direct contact with seeds (should keep 5~8 cm distance from the seeds) to prevent burning When the seed is affected, the soil moisture is better when fertilizing.
Note: Do not overuse, store the fertilizer in a cool dry place, avoid direct sunlight. If you have not used it after opening, please tighten it to protect it from moisture.
