preparation example 1

[0101] Preparation example 1: Preparation of siliceous base fertilizer

[0102] A1: react the equal mass mixture of quartz sand powder with caustic soda (i.e. solid caustic soda) and caustic potash (i.e. flaky solid KOH), and then crush the obtained solid through a 100 mesh sieve to obtain a silicon matrix;

[0103] A2: uniformly mix the silicon substrate with ammonium bicarbonate, diammonium phosphate and potassium chloride in a mass ratio of 15:1.5:2.2:1, so as to obtain the silicon base fertilizer.

preparation example 2

[0104] Preparation example 2: preparation of active fermented fertilizer

[0105] B5-1: 2 parts by weight of cottonseed meal, 1 part by weight of peanut cake, 3 parts by weight of dried chicken manure, 4 parts by weight of dried silkworm excrement, 0.1 part by weight of brown sugar, 12 parts by weight of dried plant straw powder, and 0.4 parts by weight of soybean powder , 1 part by weight of wheat bran, 1 part by weight of corn flour, 0.6 part by weight of plant ash, 4 parts by weight of dry bagasse, 3.5 parts by weight of dried distillers grains, 0.01 part by weight of cellulase, 3 parts by weight

[0106] After mixing parts of dried sawdust and 20 parts by weight of dried seaweed powder, add water and mix uniformly so that the moisture mass percentage content of the resulting mixture is 32%, and then pack the mixture with a length, width and depth of 2 meters, 1.5 meters and 1.5 meters respectively. In the fermenter, naturally accumulate and ferment for 75 hours, and ventil...

preparation example 3

[0113] Preparation Example 3: Preparation of Modified Shell Powder

[0114] C1: Crush and grind clean green clam shells, and pass through a 200-mesh sieve to obtain shell powder;

[0115] C2: calcining shell powder at 800°C for 2.5 hours, then cooling to room temperature naturally to obtain calcined powder;

[0116] C3: Add the calcined powder to the aqueous solution of ammonium sulfate and potassium chloride (the mass ratio of the calcined powder to the aqueous solution is 1:2.5), wherein the molar concentrations of ammonium sulfate and potassium chloride are 4mol / L and 3.5mol respectively / L, and then ultrasonically dispersed for 35 minutes under stirring, filtered, and dried to obtain modified shell powder, which was named BKF.

Abstract

The invention relates to multi-element silicon fertilizer as well as a preparation method and an application thereof. The multi-element silicon fertilizer is prepared from siliceous base fertilizer, alginic acid, active fermentation fertilizer, modified shell powder, compound amino acid, humic acid, metal composition, animal bone meal, sodium selenite, starch, chitosan, EDDHA-chelated iron and potassium fulvate. The multi-element silicon fertilizer has excellent effects of being good in permeability and water-retaining property, improving soil pH value and increasing crop yield through specific component selection and specific preparation methods of certain components, thereby having good application prospect and potential in the technical field of agriculture; besides, the multi-element silicon fertilizer can be in a liquid form or a solid form according to different needs and is preferably in the liquid state.

Description

technical field [0001] The invention relates to a fertilizer, more specifically to a multi-element silicon fertilizer and its preparation method and application, belonging to the fields of fertilizer chemistry and agricultural technology. Background technique [0002] At present, my country, as the most populous country in the world, has always attached great importance to food security. In addition, as a large agricultural country, my country is also the country that consumes the largest amount of chemical fertilizers in the world. [0003] According to incomplete statistics, my country's chemical fertilizer consumption in 2014 has reached more than 51 million tons, and the main types include single fertilizer and compound fertilizer. However, the long-term use of these pure chemical fertilizers also has some problems, such as large loss, soil compaction, reduction of soil nutrient activity caused by the use of a single fertilizer, environmental pollution (especially the p...
