Problems solved by technology

[0005] At present, there are mainly two dosage forms of fertilizers containing humic acid substances on the market, namely solid (powder) and liquid (aqua). The former is easy to absorb moisture and agglomerate during transportation and stacking, and has poor instant solubility when used. It also cannot play a complex role well, and is prone to precipitation under the influence of acid and alkali. Therefore, solid humic acid fertilizers are not suitable for drip irrigation fertilizers and foliar spray fertilizers, but are mostly used for flushing fertilization.
The latter uses water as the matrix, but due to the influence of the solubility of each component, the nutrient content is low, and the integration of multiple components is prone to crystallization or precipitation, and the packaging barrel is prone to flatulence during high temperature and transportation. phenomenon, so it has certain restrictions in production, storage and use

Embodiment 1

[0014] Example 1 The formula for preparing a paste-like water-soluble material based on potassium fulvic acid is shown in Table 1.

[0015] Table 1

[0016]

[0017] The preparation method is:

[0018] 1. While stirring continuously in the mixer, add potassium fulvic acid into the water until it becomes a uniform slurry, which becomes the matrix and is set aside;

[0019] 2. Grind potassium nitrate, urea, and monoammonium phosphate with a high-speed pulverizer, read carefully to more than 60 mesh, and set aside;

[0020] 3. Slowly add the above powder materials into the slurry (matrix) one by one, stir quickly and vigorously with a mixer for 30 minutes, and then it will become a paste after standing.

[0021] The above finished product is a large amount of elements instant paste fertilizer containing potassium fulvic acid, in which N, P 2 o 5 、K 2 The total amount of O is 50%, and the pH is 6-7 (measured at 1:250).

Abstract

The invention discloses a paste type water-soluble fertilizer with potassium fulvic acid serving as a matrix. The paste type water-soluble fertilizer comprises the following components in parts by weight: 80 to 100 parts of potassium fulvic acid, 200 to 650 parts of potassium nitrate, 100 to 460 parts of monoammonium phosphate, 60 to 90 parts of urea, 130 to 160 parts of water, 2.1 to 3.8 parts of calcium magnesium phosphate fertilizer, 1.6 to 2.4 parts of manganese sulfate, 0.7 to 1.2 parts of ferrous sulfate, 0.8 to 1.3 parts of zinc sulfate, 0.8 to 1.4 parts of copper sulfate, and 0.6 to 1.2 parts of ammonium molybdate. A paste type water-soluble material with potassium fulvic acid serving as the matrix can bring the colloid effect, complexing effect, acid-base equilibrium effect for all components, and interspersion effect for all material of the potassium fulvic acid into full play in the whole compound fertilizer, so that the dissolution velocity of all the materials during being diluted with water can be increased, and the content of each nutritional ingredient in the fertilizer is increased; and the paste type water-soluble fertilizer has the characteristics of being free of precipitating, hardening, crystallizing and bleeding, and can be applied to foliage spray, fertigation, etc.

Description

technical field [0001] The invention relates to a humic acid mixed fertilizer, in particular to a pasty water-soluble fertilizer with potassium fulvic acid as a matrix, which is mainly used for leaf spraying and drip irrigation and fertilization. Background technique [0002] Humic acid is a macromolecular organic substance that exists widely in nature. It is widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, and environmental protection, spanning dozens of industries. Especially the current promotion of ecological agricultural construction, pollution-free agricultural production, green food, pollution-free and environmentally friendly products, etc., makes "humic acid" highly respected. [0003] Potassium fulvic acid is a pure natural mineral active potassium element fertilizer. Potassium fulvic acid contains trace elements, rare earth elements, plant growth regulators, virus ...
