Embodiment 1

[0046] Such as figure 1 Shown flow chart prepares poly-γ-glutamic acid water-soluble fertilizer of the present invention:

[0047] 1. Dissolve 40% amino acid in 300Kg water;

[0048] 2. Add 20KG of boric acid, after dissolving, add 25KG of manganese sulfate monohydrate, 22KG of zinc sulfate monohydrate and stir to dissolve, add 3KG of sodium molybdate dihydrate and stir to dissolve, add 5KG of ferrous sulfate monohydrate and stir to dissolve, add 5KG of copper sulfate pentahydrate Stir to dissolve;

[0049] 3. Add 4% polyglutamic acid 250KG, stir to dissolve;

[0050] 4. Add water to make up to 1000L, adjust the pH to 5.5, stir evenly and let stand;

[0051] 5. Add 500g of preservative Kaisong and stir evenly;

[0052] 6. Filter with 100-mesh gauze, fill while stirring, label and pack.

[0053] The composition of the obtained fertilizer is amino acid 100g / L, polyglutamic acid: 10g / L, boron fertilizer in terms of boron: 3.4g / L, manganese additive in terms of manganese: 7.9...

Embodiment 2

[0056] Such as figure 1 Shown flow chart prepares poly-γ-glutamic acid water-soluble fertilizer of the present invention, and the component of described fertilizer is amino acid 120g / L, polyglutamic acid: 15g / L, the boron fertilizer of boron: 2g / L, manganese additive calculated as manganese: 8g / L, zinc additive calculated as zinc: 12g / L; molybdenum additive calculated as molybdenum: 2g / L; iron additive calculated as iron: 2g / L; Calculated copper additive: 2g / L; the rest is water.

[0057] Preservative Kaison 300g (3 / 10,000) pH=5.0.

Embodiment 3

[0059] Such as figure 1 Shown flow chart prepares poly-γ-glutamic acid water-soluble fertilizer of the present invention, and the component of described fertilizer is amino acid 90g / L, polyglutamic acid: 11g / L, the boron fertilizer of boron: 4g / L, manganese additive calculated as manganese: 8g / L, zinc additive calculated as zinc: 8g / L; molybdenum additive calculated as molybdenum: 1.2g / L; iron additive calculated as iron: 2g / L; Copper additive in copper meter: 2g / L; the rest is water.

[0060] Preservative sodium benzoate 300g; pH=5.2.

Abstract

The invention discloses water soluble fertilizer with poly-gamma-glutamic acid and application thereof. Compared with existing water soluble fertilizer, the adopted poly-gamma-glutamic acid is anionic polyamino acid produced through microbial fermentation, has rich side chain carboxyl, is nontoxic and harmless, has no residue, can chelate various mineral ions, and has the good effect on improving the soil structure, improving the soil moisture and fertilizer retention capacity, promoting crop root system ion exchange. Experiments prove that on the condition of ensuring normal growth of muskmelon, 300 ml of water soluble fertilizer with poly-gamma-glutamic acid is applied in each mu of field, the chemical fertilizer application amount can be reduced by 20-30%, and the cost is reduced; on the basis of ensuring the normal chemical fertilizer application amount of muskmelon, 300 ml of water soluble fertilizer with poly-gamma-glutamic acid is applied in each mu of field, so that the muskmelon yield is improved by 40-42%, and benefits are improved; in addition, the muskmelon quality is improved, and the muskmelon is more sweet, crisper and more delicious in taste.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a water-soluble fertilizer and its application. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be quickly and completely dissolved in water. With the rapid development of the integration of water and fertilizer in my country, water-soluble fertilizer has become the focus of future fertilizer development. [0003] Although my country's fertilizer production ranks first in the world, the proportion of water-saving irrigation is low. According to the research of the National Agricultural Technology Promotion Center, my country's arable land suitable for water and fertilizer integration exceeds 450 million mu, but the current national application ratio is only 3.2%, so the development potential of water-soluble fertilizers in my country is very huge. Compared with traditional fertilizers, water-soluble fertil...
