Embodiment 1

[0030] A medium-element fertilizer for conditioning and improving soil and a production method thereof. The cleaned oyster shells are put into a rotary kiln and a certain amount of coal or other fuels are added for roasting. The roasting temperature is controlled at 720° C. for 2 hours. After roasting, cool the oyster shell to about 100°C, grind it into 20-120 mesh powder by Raymond mill or other crushing equipment, and pack it into powder 1 for use;

[0031] Put the cleaned oyster shells into a drum for drying, grind them into 20-120 mesh powder by Raymond mill or other crushing equipment, and pack them into powder 2 for later use;

[0032] Powder 1 and powder 2 are mixed according to the mass ratio of 7:3 and packaged into oyster shell powder for later use;

[0033] Measure 15 parts of potassium fulvic acid, 12 parts of anhydrous magnesium sulfate, add to the mixer and stir, and at the same time inject 2 parts of polyglutamic acid with a content (GPC) ≥ 1.5% through a liquid...

Embodiment 2

[0036] A medium-element fertilizer for conditioning and improving soil and a production method thereof. Cleaned oyster shells are put into a rotary kiln and added with a certain amount of coal or other fuels for roasting. The roasting temperature is controlled at 1300° C. for 3 hours. After roasting, cool the oyster shell to about 100°C, grind it into 20-120 mesh powder by Raymond mill or other crushing equipment, and pack it into powder 1 for use;

[0037] Put the cleaned oyster shells into a drum for drying, grind them into 20-120 mesh powder by Raymond mill or other crushing equipment, and pack them into powder 2 for later use;

[0038] Add 1 part of polyglutamic acid with metering content (GPC) ≥ 20%, 15 parts of magnesium sulfate heptahydrate, 13 parts of potassium humate, add to the mixer and stir evenly, measure 71 parts of oyster shell powder, add to the mixer and continue to stir evenly, let stand After 40 minutes, after the reaction is complete, the indicators pass t...

Embodiment 3

[0041] A medium-element fertilizer for conditioning and improving soil and a production method thereof. Cleaned oyster shells are put into a rotary drum for drying, ground into 20-120-mesh powder by Raymond mill or other crushing equipment, and packaged into powder. Material 1 is ready for use;

[0042] Fully stir the powder 1 and self-made activator and pack it into powder 2 for later use;

[0043] Powder 1 and powder 2 are mixed according to the mass ratio of 8:2 and packaged into oyster shell powder for later use;

[0044] Measure 4 parts of sodium fulvic acid, 2 parts of magnesium ore powder and add them to the mixer for stirring. While stirring, inject 4 parts of polyglutamic acid with a content (GPC) ≥ 1.5% through a liquid metering pump. After spraying evenly, measure 90 parts of oyster shell powder , add the mixer and continue to stir evenly, let it stand for 30 minutes, after the reaction is complete, the index is passed the inspection, and it is packaged as a produc...

Abstract

The invention relates to a medium element fertilizer for conditioning and improving soil and a production method thereof. The medium element comprises the following raw materials: oyster shell powder, humate, magnesium-containing mineral and polyglutamic acid. By the medium element fertilizer, the organic effective combination of natural bioactive calcium, natural mineral humic acid and polyglutamic acid is achieved, the phenomenon that crops are short of medium elements in the soil is solved or alleviated and the medium element fertilizer has the effects of conditioning and improving the soil, increasing the number of bacterial communities in the soil, improving the utilization rate of soil nutrients and fertilizer nutrients, promoting the development of root systems, improving the immunity of crops, increasing the yield and improving the quality.

Description

technical field [0001] The invention belongs to the field of medium element fertilizer and its production technology, and in particular relates to a medium element fertilizer for conditioning and improving soil and a production method thereof. Background technique [0002] Medium element fertilizers mainly refer to calcium, magnesium, sulfur, silicon, these elements are stored in the soil more, and some commonly used fertilizer varieties, especially low concentration fertilizer varieties contain calcium, magnesium or sulfur elements at the same time, generally conditions to meet the needs of crops. [0003] In recent years, high-concentration fertilizers in the structure of chemical fertilizer varieties have gradually replaced low-concentration fertilizers. With the large-scale application of high-concentration nitrogen, phosphorus and potassium fertilizers without medium elements, and the reduction in the amount of organic fertilizers, some soils show crop deficiency. The ...
