Embodiment 1

[0023] A functional nutritional type liquid fertilizer containing humic acid, its weight fraction and production steps are as follows:

[0024] (1) Prepare a urea-ammonium nitrate solution, dissolve 360 ​​parts of urea and 440 parts of ammonium nitrate in 1000ml of water, and prepare a urea-ammonium nitrate solution for later use;

[0025] (2) Add 350 parts of the urea-ammonium nitrate solution obtained above into the container, then add 480 parts of cane molasses fermentation broth, stir evenly, heat up to 50°C, then add 80 parts of ammonium polyphosphate, 150 parts of potassium chloride, 20 parts of alginic acid, 30 parts of 6-BA, and 300 parts of water are continuously stirred to dissolve completely, and a functional nutritional humic acid-containing liquid fertilizer is obtained after standing to filter impurities.

Embodiment 2

[0027] A functional nutritional type liquid fertilizer containing humic acid, its weight fraction and production steps are as follows:

[0028] (1) Prepare a urea-ammonium nitrate solution, dissolve 360 ​​parts of urea and 440 parts of ammonium nitrate in 1000ml of water, and prepare a urea-ammonium nitrate solution for later use;

[0029] (2) Add 600 parts of urea-ammonium nitrate solution obtained above into the container, then add 500 parts of cane molasses fermentation liquid, stir evenly, heat up to 50°C, then add 60 parts of potassium chloride, 20 parts of alginic acid, naphthalene in turn 30 parts of acetic acid and 120 parts of water are continuously stirred to dissolve completely, and after standing to filter impurities, a functional nutritional liquid fertilizer containing humic acid is obtained.

Abstract

The invention relates to functional nutrient type liquid fertilizer containing humic acid, belonging to the technical field of fertilizer. The liquid fertilizer is prepared from the following components in parts by weight: 400-500 parts of urea-ammonium nitrate, 50-150 parts of potassium chloride, 80-120 parts of ammonium polyphosphate, 460-500 parts of fermentation broth for sugarcane molasses, 10-30 parts of alginic acid, 20-40 parts of a plant growth regulator and 200-400 parts of water. The liquid fertilizer provided by the invention is simple to prepare, stable in chemical properties andfree from precipitate, and has outstanding performance in the aspects of crop growth promotion, crop quality improvement and stress resistance.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a functional nutritional type liquid fertilizer containing humic acid. Background technique [0002] With the promotion of water and fertilizer integration technology in my country, especially the popularization of irrigation facilities, liquid fertilizer has become the first choice for irrigation and fertilization due to its diversified formula, instant and uniform advantages. [0003] Among them, humic acid-containing liquid fertilizer is a kind of liquid fertilizer, which is favored by fertilizer users because of its functions such as increasing fertilizer utilization rate, improving soil, stimulating crop growth, and improving the quality of agricultural products. [0004] However, the existing humic acid liquid fertilizers often have problems such as layered precipitation and insignificant yield increasing effect due to the requirements of their nutrient content and the ...
