Problems solved by technology

On the other hand, barley, as a crop with a high demand for nitrogen, has been widely criticized for the excessive use of chemical fertilizers in its cultivation.
Although there are many types of agricultural fungicides on the market, their market recognition is generally not high. The main reason is that the environmental adaptability and crop specificity of microorganisms are not fully considered.
[0006] Barley crops are a class of crops of great value to the national economy, but currently there is no microbial agent product specifically for barley crops, which is not conducive to the green cultivation of barley

Abstract

The invention discloses a special growth-promoting and pathogenic-bacterium-preventing agent for barley crops. The special growth-promoting and pathogenic-bacterium-preventing agent is prepared from the following raw materials: pseudomonas strain fermentation liquor, bacillus cereus strain fermentation liquor, Bacillus mycoides strain fermentation liquor, decomposed straw, potato residues, ediblemushroom residues, peat, rare earth attapulgite powder, humic acid, potassium fulvate and magnesium sulfate. The invention also provides a preparation method and application thereof. The beneficial effects of the agent are as follows: the agent is is suitable for planting barley crops such as barley and highland barley; the contained active strains can well survive on the surfaces of root systemsof barley crops and in rhizosphere soil; the symbiotic matching performance with barley crops is good; the agent has the effects of antagonizing pathogenic fungi, increasing the effective phosphorus content of soil, fixing nitrogen biologically, secreting plant hormones and the like, can play roles in promoting the growth of barley crops, preventing and treating diseases and improving the adverseenvironmental stress tolerance of the barley crops, and also has the advantages of environmental friendliness, economy, practicability, good sustainability and the like.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a special growth-promoting and anti-bacteria agent for barley crops, a preparation method and application thereof. Background technique [0002] Barley crops are a general term for annual herbaceous plants of the Gramineae family and the genus Barley. It is one of the oldest planted crops in the world. It has multiple uses such as food, feed, brewing, and medicine, and it has strong adaptability. It is planted in all parts of the north and south of my country. The ancient people of our country discovered the medicinal value of barley very early. "Tang Materia Medica" records, "Barley flour calms the stomach, quenches thirst, eliminates food, and heals swelling." , "Compendium of Materia Medica" records that barley "widens the chest and lowers the qi, cools the blood, eliminates accumulation, and eats." Modern nutritional studies have confirmed that barley is rich in nu...
