Special liquid fertilizer for cotton

Abstract

The invention discloses a special liquid fertilizer for cotton. The special liquid fertilizer comprises the following raw materials by weight: 20-26 kg of urea, 165-177 kg of monoammonium phosphate, 40-60 kg of potassium tripolyphosphate, 40-60 kg of diammonium phosphate, 2-5 kg of boric acid, 800-900 kg of soft water, 1-3 kg of fish protein powder, 5-15 kg of seaweed essence, 50-70 kg of potassium fulvate, 4-6 kg of a phosphorus activator and 3-4 kg of an NAM inhibitor. The total nutrient content of the obtained nitrogen-phosphorus-potassium product is more than 18%. The production process comprises the following specific steps of: (1) crushing and dissolving inorganic raw materials: crushing proportioned solid raw materials including urea, monoammonium phosphate, potassium tripolyphosphate, diammonium phosphate and boric acid through a raw material crushing device, putting the crushed solid raw materials into a reaction kettle, and adding proportioned soft water for dissolving; (2) dissolving auxiliary materials: adding and dissolving fish protein powder, seaweed essence, potassium fulvate, an NAM inhibitor and a phosphorus activator into the reaction kettle; (3) mixing and stirring; (4) transferring; and (5) packaging. The fertilizer is reasonable in component matching, the nutrient utilization rate is increased, and the yield and income of cotton are increased.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency ecological agriculture, and in particular relates to a special liquid fertilizer for cotton.

Problems solved by technology

[0002] At present, the fertilization method of cotton mainly adopts the fertilization method of "simplified fertilization, one base and one top dressing". , nitrogen and phosphorus utilization rate is low, and too little potassium fertilizer input seriously affects cotton yield and quality; the patent of the invention develops a special liquid fertilizer for cotton that is suitable for efficient and simplified fertilization mode through the research and development of reasonable compatibility and synergistic components, and realizes industrial application and improves Nutrient utilization efficiency, to achieve increased cotton production and income;

[0003] 1) One of the procedures in the fertilizer production process is the crushing of solid raw materials; conventionally used crushing mechanisms only initially crush the original fixed body raw materials, the degree of crushing is low, and the crushing particle size of raw materials cannot be guaranteed and distinguished, resulting in large particles Mix with small particles, and then the dissolution time of larger particles will be prolonged during the dissolution process, resulting in a large number of bubbles generated for a long time, which will affect the proportioning reaction between raw materials;

[0004] 2) Conventional crushing devices need to be shut down in the case of internal failures during the crushing process. Since most of them are integrated devices, it is necessary to clean up all the raw materials in them and then perform maintenance. The workload is large; Situations where the workload is reduced due to raw materials within the district structure
