Preparation method of slow-release photosynthetic promoting compound fertilizer

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 ...
