Problems solved by technology

[0002] At present, the base fertilizer used in corn planting is still simple nitrogen fertilizers such as ammonium bicarbonate and urea, resulting in a shortage of phosphorus and potassium fertilizers
Moreover, the nutrient release of nitrogen fertilizer is fast, the fertilizer effect is short, and it is not easy to be absorbed by crops
In hot summer, topdressing is required twice, which costs money and increases labor intensity

Embodiment Construction

[0007] The present invention is described in detail below in conjunction with embodiment.

[0008] A kind of special fertilizer for long-acting corn, its preparation method is: press the ratio of N:P:K=20:10:10, take by weighing 200 kilograms of ammonium sulfate, 500 kilograms of ammonium chloride, 400 kilograms of urea, 50 kilograms of ammonium carbonate, 250 kilograms of diammonium carbonate, 200 kilograms of monoammonium carbonate, 350 kilograms of potassium chloride, 10 kilograms of zinc sulfate, 2.5 kilograms of borax, 2.5 kilograms of NAM long-acting agent, 150 kilograms of bentonite, the above-mentioned each component raw materials in the mixer Mix evenly in the medium, transport it into the granulator by belt to granulate, dry, sieve, the particle size is 1-5mm, and dry with hot air at 80-100°C, which is the finished product.

[0009] The above-mentioned NAM long-acting agent is a commercially available product with a trade name: long-acting agent (NAM).

Abstract

The present invention relates to fertilizer, and is especially one kind of long acting corn fertilizer. The long acting corn fertilizer is prepared with ammonium sulfate 200 weight portions, ammonium chloride 500 weight portions, urea 400 weight portions, ammonium carbonate 50 weight portions, diammonium carbonate 250 weight portions, monoammonium carbonate 200 weight portions, potassium chloride 350 weight portions, zinc sulfate 10 weight portions, borax 2.5 weight portions, NAM persistent agent 2.5 weight portions, and bentonite 150 weight portions, and through mixing, palletizing, stoving at 80-100 deg.c and other steps. It has nitrogen fertilizer, phosphate fertilizer and potash fertilizer in the ratio of 20 to 10 to 10, long fertilizer efficiency, and capacity of meeting the requirement of corn in different growth stages.

Description

Technical field: [0001] The invention relates to a fertilizer, in particular to a special fertilizer for long-acting corn. Background technique: [0002] At present, the basic fertilizers used in corn planting are still simple nitrogen fertilizers such as ammonium bicarbonate and urea, resulting in a shortage of phosphorus and potassium fertilizers. Moreover, the nutrients of nitrogen fertilizer are released quickly, the fertilizer effect is short, and it is not easy to be absorbed by crops. In the hot summer, two topdressings are required, which costs money and increases labor intensity. Invention content: [0003] The purpose of the present invention is to provide a long-acting special fertilizer for corn which is formed by mixing reasonable ratios of nutrient requirements in the growth, development, and maturity stages of corn, and adding slow application, controlled application, and long-acting agents. [0004] The technical solution for realizing the above invention...
