Description

A kind of production method of organic multivariate micro-fertilizer

technical field

The invention relates to a method for producing chemical fertilizers, in particular to a method for producing organic multivariate micro-fertilizers.

Background technique

The application of micro-fertilizer is one of the key measures to achieve high yield, high quality and high efficiency of crops. Micro-fertilizers can generally be divided into inorganic micro-fertilizers and organic micro-fertilizers. However, inorganic micro-fertilizers are not easily absorbed by crops, and most of them remain in the soil as insoluble substances or are easily lost with rainwater, or have an antagonistic effect with other minerals in the soil and become invalid. Improper application will also produce some adverse consequences. Organic micro-fertilizers can solve various problems encountered in the application of inorganic micro-fertilizers, and the development of organic micro-fertilizers is one of the important directions for the development of the fertilizer industry. Organic micro-fertilizers are usually prepared through the complexation reaction of organic complexing (chelating) agents and inorganic salts of trace elements. Commonly used organic complexing agents are EDTA (ethylenediaminetetraacetic acid), citric acid, amino acid, EDDHA (ethylenediamine dihydroxyphenylacetic acid), DTPA (diethylenetriaminepentaacetic acid), HEDTA (hydroxyethylethylenediamine triacetic acid). Existing organic micro-fertilizers often use an organic complexing agent to carry out organic complexation reactions on non-metallic elements such as boron and zinc, iron, molybdenum and other metal elements. Or the deficiencies in aspects such as low complexation capacity directly affect the product quality, production cost and application effect of organic micro-fertilizers.

Contents of the invention

The object of the present invention is to provide a kind of production method of organic multivariate micro-fertilizer. It is mainly prepared by complexing various trace elements required by crops by using various organic complexing agents and step-by-step complexing processes. It can overcome the shortcomings of the existing technology and has large complexing capacity, low production cost, Balanced and lasting nutrition, easy to be absorbed by plants, high utilization efficiency, high yield increase, and obvious quality improvement.

The purpose of the present invention is achieved through the following technical solutions, and the production technology of organic multivariate micro-fertilizer is carried out according to the following steps:

① Put water with a component weight percentage of 2% to 17% into the reactor, and add nitrogen-containing organic matter with a component weight percentage of 2% to 13%. The nitrogen-containing organic matter is obtained from urea, triethylamine, ethanolamine, formazan At least one of the amides, after stirring until the added substance is miscible with water, then adding boric acid or borax with an effective boron content of 0.5% to 5.5% by weight, and stirring at 20 to 85°C for 0.5 to 6 hours to obtain Liquid organoboron is sample 1;

②Put the industrial rubber bowl extract with a component weight percentage of 3.5% to 10% into another reaction kettle, dissolve it in water with a component weight percentage of 5% to 30%, and then adjust the pH to 7.5% with sodium hydroxide. 5 or so, add hydrogen peroxide with a component weight percentage of 0.1% to 3%, and react at 20 to 85°C for 0.5 to 6 hours to prepare sample 2;

③In sample 2, add industrial humic acid with a component weight percentage of 2.5% to 8.5% to prepare sample 3;

④ Zinc sulfate with an effective weight percentage of 2% to 6.5% of the component zinc, ferrous sulfate with an effective weight percentage of 0.5% to 4.5% of the iron component, and 0.5% to 2% molybdenum with an effective weight percentage of the component ammonium molybdate, copper sulfate with an effective content of copper of 0.5% to 2.5% by weight, manganese sulfate with an effective content of manganese of 0.5% to 3.5% by weight of the component, and the balance of water are added to sample 2, at 60 to Sample 4 was prepared by complexation (chelation) reaction at 110°C for 0.5 to 4 hours;

⑤ Mix sample 4 and sample 1 and stir evenly, filter the solution with a 100-110 mesh sieve, and finally add sodium dodecylbenzenesulfonate with a component weight percentage of 1%-5% to the solution and stir evenly to obtain the final product .

The organic multivariate micro-fertilizer prepared by mixing in a certain proportion is formulated according to the nutrient demand ratio of different crops and different soil fertility types, including a variety of formula models.

The present invention will be further described below in conjunction with embodiment.

Example 1:

Put 2.2% water in the weight percentage of the components into the reactor, add 0.3% triethylamine, 1.5% ethanolamine, and 0.2% formamide in the weight percentage of the components, stir evenly, and then add the effective content of boron in the components 1% by weight boric acid was added thereto, and stirred at 80° C. for 0.5 hour to obtain liquid organoboron for later use. The rubber bowl extract with a component weight percentage of 5% is put into another reactor, dissolved in water with a component weight percentage of 10%, and the pH is adjusted to about 7.5 with sodium hydroxide, and the added component weight percentage is 1% hydrogen peroxide, react at 80°C for 1.5 hours, then add humic acid with 3% weight percentage of the components, and then add zinc sulfate with 3.5% effective content of zinc, iron, molybdenum, copper and manganese respectively , 0.5% of ferrous sulfate, 2% of ammonium molybdate, 0.5% of copper sulfate, 0.5% of manganese sulfate and the remainder of water were added to it, and the sample obtained from the complexation reaction at 80°C for 1 hour was the same as the first prepared The liquid organic boron is mixed and stirred evenly, and the solution is filtered through a 100-mesh sieve, and finally sodium dodecylbenzenesulfonate with a component weight percentage of 3% is added to the solution and stirred evenly to obtain the final product.
