preparation example Construction

[0031] The embodiment of the present invention also provides a preparation method of selenium-enriched liquid fertilizer, comprising:

[0032] Prepare the EM bacterial liquid, wherein, preferably, the EM bacterial liquid is obtained by mixing and culturing the EM original bacterial liquid, brown sugar water and biogas slurry according to a weight ratio of 0.4-0.6:4-6:15-25 for 20-28 hours. Brown sugar water can promote the reproduction of the flora in the EM original bacterial liquid, to help the rapid combination of the bacterial flora in the EM original bacterial liquid and the organic matter in the biogas slurry; the weight ratio of the EM original bacterial liquid to brown sugar water and biogas slurry According to the inventiveness test, the EM bacterial solution prepared within the ratio range has a stronger ability to convert inorganic selenium into organic selenium.

[0033]Then, in parts by weight, 20-25 parts of EM bacteria solution, 13-20 parts of mushroom dregs, an...

Embodiment 1

[0039] This embodiment provides a selenium-enriched liquid bacterial fertilizer. In parts by weight, its raw materials include: 70 parts of biogas slurry, 13 parts of mushroom dregs, 21 parts of EM bacteria liquid, 0.8 parts of EM original bacteria liquid, and 3.3 parts of CM bacteria , 0.3 parts of sodium selenite, and 4 parts of brown sugar.

[0040] This example provides a method for preparing selenium-enriched liquid bacterial fertilizer, comprising: dissolving 4 parts of brown sugar in water to prepare brown sugar water, mixing 0.4 parts of EM original bacterial liquid with 4 parts of brown sugar water and 15 parts of biogas slurry for 20 -28 hours to get the EM bacterial liquid.

[0041] Add 20 parts of EM bacterial liquid, 13 parts of mushroom dregs, and 1.5 parts of CM bacterial liquid to 70 parts of biogas slurry, adjust the pH value to 7.0, and carry out the first fermentation to obtain the first fermentation liquid; add 1 part of EM bacterial liquid again , 0.1 par...

Embodiment 2

[0044] This embodiment provides a kind of selenium-enriched liquid bacterial fertilizer. The raw materials include: 85 parts of biogas slurry, 20 parts of mushroom dregs, 28 parts of EM bacterial liquid, 1.2 parts of EM original bacterial liquid, and 4.7 parts of CM bacteria in parts by weight. , 0.75 parts of sodium selenite, and 6 parts of brown sugar.

[0045] This example provides a preparation method of selenium-enriched liquid bacterial fertilizer, comprising: dissolving 6 parts of brown sugar in water to prepare brown sugar water, mixing 0.6 parts of EM original bacterial liquid with 6 parts of brown sugar water and 25 parts of biogas slurry for 20 -28 hours to get the EM bacterial liquid.

[0046] Add 25 parts of EM bacterial liquid, 20 parts of mushroom dregs, and 2.5 parts of CM bacterial liquid to 85 parts of biogas slurry, adjust the pH value to 7.0, and carry out the first fermentation; add 3 parts of EM bacterial liquid and 0.4 part of selenous acid Sodium solut...

Abstract

The invention provides rich-in-selenium liquid bacterial manure, a preparation method and application, and belongs to the technical field of agricultural biology. The raw materials of the rich-in-selenium liquid bacterial manure comprise biogas slurry, mushroom slag, EM bacteria solution, EM raw bacteria solution, CM bacteria, selenite and brown sugar. The rich-selenium liquid bacterial manure can provide various nutrition elements for vegetables for promoting the growth. The preparation method of the rich-in-selenium liquid bacterial manure comprises the following steps of adding partial EM bacteria solution, mushroom slag and partial CM bacteria solution into the biogas slurry; regulating the pH value; performing primary fermentation to obtain first fermentation solution; mixing the rest EM bacteria solution and the partial selenite solution with the first fermentation liquid; after 4 to 6 days, adding partial EM raw bacteria solution, the rest CM bacteria solution and the rest selenite solution; performing secondary fermentation to obtain the rich-in-selenium liquid bacterial manure. The preparation method has the advantages that the technology is simple; the selenium liquid bacterial manure with the excellent performance can be effectively prepared. The preparation method of the rich-in-selenium liquid bacterial manure can be applied to leaf fertilizers or root irrigation fertilizers.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a selenium-enriched liquid fertilizer and its preparation method and application. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, people gradually begin to have higher and higher requirements for the quality of life; they also pay more and more attention to food safety. [0003] At present, organic ingredients are becoming more and more sought after by everyone, and a large amount of organic fertilizer is needed in the process of planting organic ingredients; however, farm organic fertilizer degrades slowly and has low utilization efficiency, which is not conducive to large-scale production and use; the general bacterial fertilizer fermentation cycle Long, which limits the large-scale and rapid production of bacterial fertilizer, which is not conducive to production and application.
