Problems solved by technology

[0003] At the same time, in the process of planting, light is an important environmental factor that affects the yield and quality of plants. Especially during the later period of plant fruit growth, haze, rain, etc. will have a huge impact on plant yield. How to alleviate the impact of harsh environmental conditions on plants? The adverse effects caused by production have been a hot issue that everyone has paid attention to in recent years. Artificial light supplementation technology can improve the lack of illumination to a certain extent, but it has the problems of high cost and limited use of space.

Embodiment 1

[0027] A preparation method of a slow-release type photosynthesis-promoting compound fertilizer, comprising the following steps:

[0028] (1) Take plant straw, livestock and poultry manure, fulvic acid, and fungus slag, mix them according to the mass ratio of 65:18:7:1, grind them, put them into a fermenter for sealed fermentation, and turn them over every 3 days during fermentation. Turn the bottom fermented material to the top layer one time at a time, control the temperature in the center of the fermented heap to not exceed 70°C during the fermentation period, and continue the fermentation for 20 days to obtain the decomposed fermented material;

[0029] (2) Air-dry the above-mentioned decomposed fermented material and pulverize it through a 40-mesh sieve, then add 3% oxidized glutathione and 10% superphosphate and potassium nitride of the pulverized material to the pulverized material, mix and send Pellet in the granulator, control the particle size between 3-8mm, and re-g...

Embodiment 2

[0033] A preparation method of a slow-release type photosynthesis-promoting compound fertilizer, comprising the following steps:

[0034] (1) Take plant straw, livestock and poultry manure, fulvic acid, and fungus slag, mix them according to the mass ratio of 75:22:9:3, grind them, put them into a fermenter for sealed fermentation, and turn over the pile every 5 days during fermentation. Turn the bottom fermented material to the top layer one time at a time, control the temperature in the center of the fermented heap to not exceed 70°C during the fermentation period, and ferment for 30 days to obtain decomposed fermented material;

[0035] (2) After the above-mentioned decomposed fermented material is air-dried, it is pulverized through a 60-mesh sieve, and then oxidized glutathione and 15% ammonium nitrate and calcium magnesium phosphate fertilizer are added to the pulverized material, and sent into the Granulate in the granulator, control the particle size between 3-8mm, and...

Embodiment 3

[0039] A preparation method of a slow-release type photosynthesis-promoting compound fertilizer, comprising the following steps:

[0040] (1) Take plant straw, livestock and poultry manure, fulvic acid, and fungus slag, mix them according to the mass ratio of 70:20:8:2, crush them, put them into a fermenter for sealed fermentation, and turn over the pile every 4 days during fermentation. Turn the bottom fermented material to the top layer one time at a time, control the temperature in the center of the fermented heap to not exceed 70°C during the fermentation period, and continue the fermentation for 25 days to obtain the decomposed fermented material;

[0041] (2) After air-drying the above-mentioned decomposed fermented material, crush it through a 50-mesh sieve, then add 4% oxidized glutathione and 12% monoammonium phosphate and plant ash to the crushed material, and send it into the mill after mixing. Granulate in the granulator, control the particle size between 3-8mm, an...

Abstract

The invention discloses a preparation method of a slow-release photosynthetic promoting compound fertilizer. The preparation method comprises the following steps: (1) mixing plant straw, livestock andpoultry manure, fulvic acid and mushroom dregs, pulverizing, sending into a fermentation tank, and carrying out sealed fermentation to obtain a decomposed fermentation material; (2) air-drying the decomposed fermented material, crushing, adding oxidized glutathione and inorganic nutrient powder into the crushed material, uniformly mixing, and feeding into a granulator for granulation; (3) mixingpolyvinyl alcohol and water, heating and stirring until the polyvinyl alcohol and the water are completely dissolved, and sequentially adding chitosan and silicon dioxide to obtain a coating agent; and (4) immersing the obtained particles into a coating agent, taking out the particles, and blow-drying the particles to constant weight at normal temperature to obtain the compound fertilizer. The compound fertilizer is simple in preparation method, easy for large-scale production in factories, balanced in nutritional ingredients, and capable of powerfully promoting photosynthesis during plant growth, and provides powerful technical support for reducing planting labor input and increasing crop yield.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a preparation method of slow-release photosynthesis-promoting compound fertilizer. Background technique [0002] In the current production of food crops, there is a long-term use of single chemical fertilizers, which will lead to low nutrient utilization, soil fertility, soil sustainable production capacity, and the inability to ensure stable and high grain yields. However, long-term application of organic fertilizers can maintain soil production functions. The combined application of organic fertilizers and conventional chemical fertilizers (that is, the application of organic fertilizers instead of part of chemical fertilizers) has been paid more and more attention to production. This method is also a fertilization method that is gradually promoted from national to local agricultural production. . That is, an organic-inorganic compound fertilizer with certain functions is ...
