Problems solved by technology

However, at present, most of the water-soluble fertilizers in my country are single fertilizers containing large amounts of nitrogen, phosphorus, potassium or medium and trace elements. Long-term application of single chemical fertilizers will easily cause soil agglomeration, fertility degradation, and crop quality decline.
At the same time, most domestic water-soluble fertilizer products use high-water-soluble raw materials or use physical methods to grind the raw materials to improve the water-solubility of the product. These methods are all costly and fail to solve the problem of nozzle clogging.
In the north, the content of calcium, magnesium and iron in water is high, which forms insoluble phosphate with water-soluble phosphorus sources in fertilizers (such as ammonium hydrogen phosphate, potassium phosphate, etc.), which blocks the nozzles and reduces the efficiency of facilities.

Embodiment 1

[0025] A balanced macronutrient water-soluble fertilizer consists of the following components in parts by weight:

[0026] Inorganic fertilizer is calculated as N+P2O5+K2O, 18-30 parts;

[0027] 6-10 parts of medium and trace element additives, wherein the medium and trace element additive is EDTA complex;

[0028] Seaweed extract, 6-10 parts;

[0029] Functional additives, 2 to 4 parts;

[0030] Microbial additives, 2 to 4 parts;

[0031] Water-soluble initiator, 1-3 parts;

[0032] Water-soluble synergist, 1-3 parts;

[0033] Wherein, the EDTA complex is one or more mixtures of EDTA complexes of calcium, magnesium, copper, iron, zinc, manganese, and molybdenum; the functional additives are: γ-polyglutamic acid, A mixture of fulvic acid and 5-aminolevulinic acid in a mass ratio of 1:1:2; the microbial additive is a mixture of Bacillus subtilis and Pseudomonas fluorescens in a ratio of 2:1; the water-soluble The initiator is a mixture of sodium polyacrylate and carboxyme...

Embodiment 2

[0038] The fertilizer efficiency of the water-soluble fertilizer of the present invention is compared with that of the commercially available water-soluble fertilizer, and the preparation method of the fertilizer refers to Example 1.

[0039] experimental method

[0040] The experiment was carried out locally, and 4 cabbage fields were selected. The cabbage variety was Beijing Chinese cabbage, and each plot was one mu. Among them, 3 plots were the experimental area and the other was the control area. The experiment starts from the cabbage planting, and the experimental area is fertilized twice, the first time when the cabbage seedlings are fertilized with the fertilizer of the embodiment 1 of the present invention and the comparative example, 50 jin per mu, and for the second time when the cabbage is in the core stage. Embodiment 1 of the present invention and the fertilizer of comparative example carry out soil fertilization, 40 jins per mu, except that no fertilizer is appli...

Embodiment 3

[0044] Research on Increasing Production and Reducing Insect Pests of Cucumber

[0045] experimental method

[0046] The experiment was carried out with cucumbers in spring, and 4 cucumber fields were selected, each 20m2, of which 3 were experimental areas and the other was a control area. The experiment starts from cucumber planting, and the experiment area is applied the fertilizer of the embodiment 1 of the present invention and the comparative example when the cucumber seedlings and results are produced, 40 jin / mu each time, and the soil is fertilized. In the control area, except that no fertilizer was applied, the other treatment experimental areas were the same as the control area.

[0047] The growth rate and fruit quantity of cucumbers in the experimental area were better than those in the control area, wherein the cucumber field using the fertilizer of Example 1 had the fastest growth rate and produced the most cucumbers, followed by the cucumber field using the fert...

Abstract

The invention discloses a balanced macro-element water-soluble fertilizer which is characterized in that the water-soluble mineral additive comprises, by weight, 18-30 parts of inorganic fertilizers comprising N, P2O5 and K2O, 6-10 parts of medium trace element additives, 6-10 parts of sea algae extracts, 2-4 parts of functional additives, 2-4 parts of microbial additives, 1-3 parts of water-soluble initiators and 1-3 parts of water-soluble synergist. The medium trace element additives are EDTA (ethylene diamine tetraacetic acid) complexes.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a balanced macroelement water-soluble fertilizer. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops. It also has a relatively high absorption and utilization rate, realizes the integration of water and fertilizer, and saves water, fertilizer and labor. It is a new type of fertilizer that has emerged in recent years. my country's water resources are in short supply, and the share used for agricultural production is also declining, which has become a very serious problem. With the continuous and rapid development of China's economy, it is affected by factors such as the gradual improvement of people's living standards and rapid population growth, and The demand for the output and quality of food and agricultural produ...
