Efficient plant fertilizer

Abstract

The invention relates to efficient plant fertilizer, which is the plant growth fertilizer, wherein a polybasic acid is adopted as a main agent, ammonium nitrohumate, dicyandiamide, chemical engineering raw materials such as potassium tartrate, potassium dihydrogen phosphate and the like, a plurality of metal ions adopting as the trace elements, an organic matter and a regulator are added to the main agent to form the plant growth fertilizer. The blending method comprises: fusing the chemical engineering raw materials; adding the fused chemical engineering raw materials to the polybasic acid; heating and melting the trace elements; blending the chemical engineering raw materials, the main agent and the trace elements in the blended solution; carrying out a reaction for 25 minutes under an environment with a temperature of 70 DEG C; adding the amine to the resulting solution, and carrying out a reaction to obtain the ammonium nitrohumate; then adding the dicyandiamide to the ammonium nitrohumate, and stirring. With the present invention, the one-time fertilizer application problem can be solved, the fertilizer utilization rate can be increased by about 20%, the fertilizer is slowly released in the soil, and uniformly provides the nutrients for the crop during the whole growth period, the nitrite content in the soil is reduced, and the pollution to the soil and the groundwater is reduced.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-efficiency plant fertilizer. Background technique [0002] At present, chemical fertilizers are more and more widely used in agricultural production. Its use has greatly improved the output of agricultural products, but at the same time it has exposed the shortcomings of chemical fertilizers themselves. One is to bring pollution to the air and groundwater, destroying the original structure of the land; the other is that chemical fertilizers are volatile and the utilization rate is not high; the third is to affect people's health. Contents of the invention [0003] In order to solve the defects of the prior art, the present invention proposes a high-efficiency plant growth fertilizer. [0004] The technical solution of the present invention is: a high-efficiency medicinal fertilizer for plant growth, which is prepared by adding polybasic acid as the main agent, adding am...
