High Tower Compound Fertilizer Application Technology
High tower compound fertilizer, also known as high-nitrogen compound fertilizer, uses a fully automatic computer-controlled batching to melt urea, phosphorus, potassium and other raw materials. After being fully melted, it is sprayed from the top of the tower and vacuum granulated. Its high nutrient content, high-efficiency, uniform particles, good-looking appearance, melting holes and natural anti-counterfeiting are the fertilizers that farmers particularly like to use high nitrogen and have obvious effects. The specific application techniques are as follows:
First, the scope of application:
There are mainly 30-10-11, 25-10-16, and 20-10-10 compound fertilizers for high-column compound fertilizers, which are suitable for various field crops and economic crops. Such as wheat, corn, rice, cotton, etc., can do base fertilizer and top dressing. Particularly suitable for fertilizing corn, cotton top dressing, leafy vegetables, lawns, pastures, Chinese herbs, and fruit trees. The use of high-tower compound fertilizers for corn and cotton is more efficient than the use of single nitrogen fertilizer, which results in high fertilizer utilization, less environmental pollution, and lack of soil compaction, which can significantly increase yield and improve the quality of agricultural products.
Second, note:
1. Avoid smoked leaves. In some parts of China, farmers apply fertilizing habits on most crops, and fertilizers are spread on the surface. Because they cannot be fully absorbed and utilized by crops, the nitrogen in high-column fertilizer will form ammonia, and will directly evaporate into the air. Leaves are smoked and affect their photosynthesis. Therefore, the high-tower compound fertilizer must be fertilized and applied to the soil in the high-temperature season as top-dressing, or it must be ventilated and exhausted to avoid gaseous ammonia-smoked leaves during flushing in the greenhouse.
2, to prevent burning roots. If the tower compound fertilizer is applied too shallowly or under plastic film mulching conditions, nitrogen is less likely to be produced at the seedling stage of the crop, so the nitrogen in the compound fertilizer will generate ammonia, which will not be emitted into the air, and it will easily lead to burning. Root phenomenon. For this reason, high-column compound fertilizers must be applied deeply to prevent burning of roots.
