Problems solved by technology

[0004] At present, in the prior art, adding fulvic acid to fertilizers is mostly used to improve the fertility of saline-alkali soil, but due to the low dissolution rate of fulvic acid itself, and in the process of dissolving other fertilizers, especially the dissolution of potassium fertilizer and phosphate fertilizer It is also an exothermic process and highly corrosive, so a large amount of water must be used to dilute and cool down, resulting in a low content of fulvic acid in the fertilizer and high fertilization costs

Embodiment 1

[0042] Example 1: High-concentration fulvic acid and high-efficiency liquid fertilizer

[0043] The present invention specifically provides a high-concentration fulvic acid high-efficiency liquid fertilizer, which contains 170-190 parts of fulvic acid concentrated solution, 450-470 parts of monoammonium phosphate, 210-230 parts of potassium hydroxide, and 90 parts of urea in parts by weight. -110 parts, 40-60 parts of potassium phosphite, 30-34 parts of boric acid, 120-180 parts of fulvic acid functional additives.

Embodiment 2

[0044] Example 2: Preparation of fulvic acid functional additives in high-concentration fulvic acid and high-efficiency liquid fertilizer

[0045] In the present invention, the fulvic acid functional additive contains 30-35% of microbial restoration agent, 30-35% of fermented walnut green husk, 20-25% of compound amino acid, and 10-15% of stabilizer in terms of weight percentage.

[0046] In the present invention, the compound amino acid is configured according to the volume ratio of L-alanine:L-valine:L-glutamic acid:L-threonine=2:3:1:2.

[0047] In the present invention, the stabilizer is preferably configured according to the volume ratio of sodium alginate: gelatin: polyvinyl alcohol = 2:1:1.

Embodiment 3

[0048] Example 3: Preparation of high-concentration fulvic acid and high-efficiency liquid fertilizer

[0049] The preparation method of high-concentration fulvic acid high-efficiency liquid fertilizer, the specific preparation method steps are as follows:

[0050] (1) After adding water to the container, add monoammonium phosphate and stir to dissolve, slowly add potassium hydroxide, stir until completely dissolved, then add urea and stir to dissolve, add fulvic acid concentrate, stir and mix well, then add boric acid until completely dissolved to obtain a mixed solution;

[0051] (2) adding water to dissolve potassium phosphite for subsequent use;

[0052] (3) Slowly pour the potassium phosphite solution prepared in step (2) into the mixed solution prepared in step (1), stir and mix and add the functional additive of fulvic acid, that is, add microbial restoration agent, walnut green husk fermentation liquid, compound Amino acids, stabilizers and a certain amount of water ...

Abstract

The invention discloses a high-concentration fulvic acid high-efficiency liquid fertilizer and application thereof. The high-concentration fulvic acid high-efficiency liquid fertilizer is prepared bymixing 180 parts of a concentrated fulvic acid solution, 460 parts of monoammonium phosphate, 220 parts of potassium hydroxide, 100 parts of urea, 50 parts of potassium phosphite, 32 parts of boric acid and 150 parts of a fulvic acid functional additive; the prepared high-concentration fulvic acid high-efficiency liquid fertilizer has the effects of increasing yield and income, remarkably enhancing tree vigor and expelling parasites, and remarkably improving crop quality; a microbial remediation agent in the fulvic acid functional additive can effectively activate soil regeneration elements and accelerate the growth activity of organic matters in soil; and the fertilizer can improve soil fertility and restore soil, has a remarkable restoration effect on saline-alkali soil, can remarkably inhibit proliferation of harmful bacteria and injurious insects, is beneficial for improving the yield and quality of red dates and walnuts, and achieves a remarkable and outstanding technical effect.

Description

technical field [0001] The invention relates to the technical field of application of agricultural microorganisms, in particular to the technical field of high-concentration fulvic acid and high-efficiency liquid fertilizer and its application. Background technique [0002] Soil fertility in Xinjiang has the following characteristics: ①Soil organic matter is poor, and the foundation of soil fertility is poor; ②The soil is light, lacks clay and cement, and has poor structure, which is not conducive to the coordination of water, fertilizer, air, and heat, and affects fertilizer supply; ③ The mineralization process is strong, the fertilizer supply intensity is high, and the effective nutrients are few. More than 80% of the total phosphorus in the soil is consolidated by lime. In different areas of Xinjiang, the degree of barren soil, the degree of nutrient solidification and the degree of soil desertification are relatively high, and the micro-ecological balance has deteriorate...
