Embodiment 1

[0019] Embodiment one: a kind of preparation method containing humic acid concentrated chelated trace element fertilizer, the method is as follows:

[0020] Ⅰ. Mix 70% furfural slag, 20% crop straw, and 10% farmyard manure evenly, add furfural wastewater to keep the water content at about 40%, control the temperature at about 50°C, and carry out in the fermentation greenhouse For fermentation, turn the pile mechanically once every two days until the organic matter such as humic acid reaches 60% to 70%, and the fermentation ends. After the furfural residue is fermented and decomposed, it is rolled out from the fermentation shed and stacked for later use.

[0021] Ⅱ. Mix 70% of fermented and decomposed furfural residue with 30% of 4% potassium hydroxide solution, stir at 70°C for 1 hour, and perform centrifugation to obtain humic acid-containing supernatant.

[0022] Ⅲ. First add the supernatant containing 46.2% humic acid, 27.25% disodium edetate and 2.93% sodium hydroxide int...

Embodiment 2

[0023] Embodiment two: a kind of preparation method containing humic acid concentrated chelated trace element fertilizer, the method is as follows:

[0024] Ⅰ. Mix 75% furfural slag, 17% crop straw, and 8% farmyard manure evenly, add furfural wastewater to keep the water content at about 45%, control the temperature at about 55°C, and carry out in the fermentation greenhouse For fermentation, turn the pile mechanically once a day until the organic matter such as humic acid reaches 60% to 70%, and the fermentation is over. After the furfural residue is fermented and decomposed, it is rolled out from the fermentation shed and stacked for later use.

[0025] Ⅱ. Mix 80% fermented and decomposed furfural residue with 20% potassium hydroxide with a concentration of 2%, stir at 80°C for 1.5h, and filter off the supernatant.

[0026] Ⅲ. Add 49.2% humic acid supernatant, 23.25% ethylenediaminetetraacetic acid disodium and 2.66% sodium hydroxide to the reaction kettle in turn, stir unt...

Embodiment 3

[0027] Embodiment three: a kind of preparation method that contains humic acid concentrated chelated trace element fertilizer, the method is as follows:

[0028] Ⅰ. Mix 80% furfural slag, 15% crop straw, and 5% farmyard manure evenly, add furfural wastewater to keep the water content at about 50%, control the temperature at about 60°C, and carry out in the fermentation greenhouse For fermentation, turn the pile mechanically once a day until the organic matter such as humic acid reaches 60% to 70%, and the fermentation is over. After the furfural residue is fermented and decomposed, it is rolled out from the fermentation shed and stacked for later use.

[0029] Ⅱ. Mix 90% of the fermented and decomposed furfural residue with 10% of 3% potassium hydroxide, stir at 90°C for 2 hours, and filter off the supernatant.

[0030] Ⅲ. Add 43.2% humic acid supernatant, 31.25% edetate disodium and 3.26% sodium hydroxide to the reaction kettle in turn, stir until dissolved; then add 5.46% z...

Abstract

The invention relates to a method for preparing a fertilizer containing trace elements, and particularly relates to a method for preparing a fertilizer containing humic acid concentrated chelating trace elements. The method comprises the following steps of firstly, adding supernate containing humic acid, ethylene diamine tetraacetic acid and sodium hydroxide sequentially into a reaction kettle, and stirring until dissolving; then adding heptahydrate, manganese sulfate monohydrate, blue copperas and iron vitriol sequentially into the reaction kettle, chelating, and stirring until dissolving; and then adding boric acid, ammonium molybdate, citric acid, caprylyl / capryl glucoside APG0810 into a reaction kettle, and stirring until dissolving. The invention provides a plant growth adjusting agent which is high in nutritional element concentration, is stable and uniform in solution, contains biochemical humic acid and the like, is beneficial to plant absorption, is high in biodegradability and is low in blade and soil pollution.

Description

technical field [0001] The invention relates to a preparation method of a trace element fertilizer, in particular to a preparation method of a concentrated chelated trace element fertilizer containing humic acid. Background technique [0002] Trace element fertilizers refer to fertilizers containing trace elements, which are less absorbed and consumed by plants, but they are equally important to crops like macro elements and cannot be substituted for each other. Micro-fertilizers have been proved to have a certain biological significance after a large number of scientific experiments and researches. They are indispensable nutrients for the normal growth and development of plants. The trace elements necessary for plant growth and their percentages in dry weight of crops are: manganese 0.05%, iron 0.02%, zinc 0.01%, boron 0.005%, copper 0.001%, molybdenum 0.0001%. [0003] In recent years, in agricultural production, the lack of trace elements has become increasingly serious,...
