Embodiment 1

[0017] Embodiment 1: a kind of multi-element chelate sol fertilizer, it is to make by following preparation process.

[0018] (1) Acid hydrolysis: add hoof horn powder and 6mol / L H in the reaction kettle 2 SO 4 , the weight ratio of the two is 1:4, stirring and hydrolyzing at 60-80° C. for 12-20 hours, after the hydrolysis is completed, the acid hydrolyzate is separated, and the residue is set aside.

[0019] (2) Alkaline hydrolysis: add the residue obtained in step (1) and 3mol / L KOH solution in the reaction kettle, the weight ratio of the residue to the lye is 1:10, stir and hydrolyze at 60-80°C for 4h, and then An ammonia absorption device is installed on the kettle, and the absorption liquid used is dilute phosphoric acid with a concentration of 1:1. After hydrolysis, the alkali hydrolyzate and a small amount of residue are separated, and the alkali hydrolyzate and absorption liquid are combined into an alkali combined liquid for later use, and a small amount of residue i...

Embodiment 2

[0022] Embodiment 2: a kind of above-mentioned multi-element chelating fertilizer, it is to make by following preparation process.

[0023] The steps are the same as in Example 1, and then the following steps are carried out, (4) Polymerization and gelation: put the mixed solution in the reaction kettle, add trace nutrients, stir at 60°C to 80°C, make it fully mixed and concentrated for 3~ 4h, until the specific gravity is 1.08, add 1.5% solubilizer by weight of the concentrated solution. Said solubilizing agent is the glucomannan extracted from Araceae plants, and it is gelatinized after insulated and stirred for 3 hours; (5) The adjustment steps of N, P, K nutrient ratio: add urea, Potassium dihydrogen phosphate adjusts the ratio of nitrogen, phosphorus, and potassium nutrients, and then stirs and keeps warm for 3 to 4 hours to dissolve the added raw materials and disperse the glue evenly.

[0024] The organic nutrient content of the present embodiment ≥ 15%, N, P 2 o 5 、...

Abstract

A multiple elements chelated sol fertilizer rich in organic nutrients, N, P2O5 and K2O is prepared through acid hydrolyzing, separating the acidic hydrolytic liquid from dregs, alkali hydrolyzing to said dregs, using the absorbing liquid to absorb ammonia, separating alkaline hydrolytic liquid from dregs, mixing the alkaline hydrolytic liquid with said absorbing liquid circulation use of dregs, regulating the pH value of said acidic hydrolytic liquid to 2.5-3.5, mixing it with said liquid mixture, regulating pH=5-6, concentrating, and adding solubilizer.

Description

Technical field: [0001] The invention relates to a multi-component chelating sol fertilizer and a preparation process thereof. Background technique: [0002] According to the estimates of the Food and Agriculture Organization of the United Nations, 55% of the increase in food production in developing countries comes from the contribution of chemical fertilizers. However, in the use of chemical fertilizers, the deterioration of the ecological environment caused by the lack of scientific management is also becoming more and more serious, which has directly threatened the living environment of human beings and has aroused widespread concern from governments of various countries. my country is a large agricultural country with a large population. The per capita arable land is small and the reclaimable land is extremely limited. Since the 1960s, my country's grain production has mainly been increased by the input of chemical fertilizers. As the amount of chemical fertilizers inc...
