Abstract

The invention discloses a special fertilizer for high-tower urea-formaldehyde slow-release bananas and a preparation method thereof, relating to the technical field of agricultural fertilizers. The special fertilizer for high-tower urea-formaldehyde slow-release bananas is prepared from urea, monoammonium phosphate, potassium chloride, formaldehyde, humic acid, calcium magnesia phosphate fertilizer, EDTA (ethylene diamine tetraacetic acid) chelated boron and additives. Compared with common fertilizers, the fertilizer disclosed by the invention can obviously enhance the yield and greatly reduce the fertilizer application frequency, thereby saving the labor cost, enhancing the economic benefit and being worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for high-tower urea-formaldehyde slow-release bananas. Background technique [0002] After urea is applied to the soil, it will quickly dissolve and be converted into ammonia nitrogen and nitrate nitrogen under the action of urease in the soil, so its fertilizer effect is short, and part of the nitrate nitrogen will be leached or lost with rainwater or irrigation water. There is also a part of ammonia nitrogen volatilization loss, so the nitrogen utilization rate is low. Therefore, improving the utilization rate of chemical fertilizers and reducing the environmental pollution caused by fertilization has become an urgent issue. The application of slow-release and controlled-release fertilizers can maximize the utilization rate of nitrogen in fertilizers, which has become the focus and hotspot of chemical fertilizer research. . [0003] Banan...
