Abstract

The invention relates to a filler-free blended fertilizer consisting of urea, monoammonium phosphate, potassium chloride, ammonium chloride and poly-gamma-glutamic acid, wherein the filler-free blended fertilizer has the formulation based on parts by weight: 3-41 parts of urea with 46% of N, 12-60 parts ammonium chloride with 20-25% of N, 25-45 parts of monoammonium phosphate with 45-55% of P2O5, 23-28 parts of potassium chloride with 60% of K2O, and 0.1-1 part of poly-gamma-glutamic acid. The blended fertilizer has the advantages that the blended fertilizer is free of filler, thus being attractive in appearance, and good in water solubility. The filler-free blended fertilizer is scientific and reasonable in proportion, but the production cost is only 1949 RMB / ton, so that the cost is saved about 441 RMB / ton compared with the cost of the original filler-containing blended fertilizer. The filler-free blended fertilizer is simple in technology, so that the filler-free blended fertilizer can be prepared by mixing raw materials according to the formulation proportion.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers. technical background [0002] At present, the known N, P, and K contents are 26-10-12 blended fertilizers. In order to reduce production costs, filler white clay is added to its production formula. For example, the original formula produced by our factory is: [0003] Urea 48.6 containing 46% N containing K 2 O 60% KCl 18.3 [0004] Contains P 2 o 5 Amount of 55% monoammonium phosphate 26.7 filler (clay) 6.6 [0005] The production cost of its blended fertilizer is 2606.93 yuan / ton. Due to the addition of fillers, it has poor appearance quality and poor water solubility. Contents of the invention [0006] The purpose of the present invention is to provide a kind of additive-free blended fertilizer for the problems that currently produced agricultural blended fertilizers are all added with fillers, poor appearance quality, and poor water solubility. The present invention consists of...
