Problems solved by technology

However, in the actual large-scale industrial production, the plant ash auxiliary materials used mainly come from straw incineration power plants. In the process of straw incineration, in order to support combustion, additional combustion aids such as pulverized coal and diesel oil need to be added. The EC value of the plant ash produced in this way is very low. High, often around 14mS/cm, so even adding 8-10% plant ash will make the EC value of the final substrate product high, generally around 3.6mS/cm, and th

Embodiment 1

[0020] Raw material preparation process: select 30 tons of raw vinegar lees associated with the production process of Jiangsu Hengshun Vinegar Industry Group. After inspection, its water content is 73%, and its pH value is 4.6. Use a roller press to filter out 7 tons of vinegar lees water. Obtaining water content is 23 tons of raw material vinegar grains of 50%, press raw material vinegar grains 98%, add a kind of urea 0.24 tons of nitrogenous fertilizer in the ratio of nitrogen source 2%, evenly mix, obtain pH value 4.6, water content 50%, C / 23.24 tons of fermented material with N ratio of 25:1.

[0021] Bacteria adding and mixing process: adding 23.24 kg of composite microbial bacterial agent with a percentage by weight of 1‰, and mixing evenly. The composite microbial strains include mould, bacillus, lactic acid bacteria, yeast, and actinomycetes, and the number of effective viable bacteria is more than or equal to 5 billion / g.

Embodiment 2

[0027] Mix soil and peat soil at a volume ratio of 2:1 to make a peat substrate, and its blueberry cultivation test effect (survival rate and plant sturdiness) is used as a control; 3:1, 2:1, 1:1, and 0:1 volume ratios were used to investigate the effect of blueberry cultivation experiments. The results show that: after soil and the special-purpose cultivation substrate for blueberries are mixed by 3:1, the effect of its blueberry cultivation is equivalent to that of the peat substrate of the control group; along with the increase of the addition ratio of the special-purpose cultivation substrate for blueberries, the survival rate of blueberries and the degree of plant sturdiness All showed an increasing trend; when soil and unfermented vinegar grains were mixed in a volume ratio of 3:1, 2:1, 1:1, and 0:1, blueberry seedlings could not grow.

[0028] Since peat is a non-renewable resource, unreasonable exploitation will also cause environmental damage. Therefore, the state has...

Abstract

The invention provides a special culture medium for a blueberry and a production process thereof, belonging to the technical field of crop cultivation. According to the invention, vinegar residues are used as a main material, 1 to 5% of urea is added to adjust a carbon-nitrogen ratio to 25: 1 to 20: 1; 0.1 to 0.5% of a composite microbial strain is added; after completion of microbial fermentation and decomposition, the pH value of a material is 6.7 to 6.9 and is adjusted to 4.5 to 5.0 by using tail vinegar; and a finished product procedure is carried out so as to prepare the special culture medium for the blueberry. The special culture medium for the blueberry is an acidic granular medium containing no less than 60% of organic matters, 4.0 to 4.5% of total nutrients, 30 to 35% of moisture content, a soluble ion concentration EC value of 1 to 2 mS/cm, 22 to 25% (V) of ventilation porosity and 44 to 46% (V) of water-retention porosity. Test results show that the special culture medium for the blueberry is used for blueberry cultivation and has better effect than a turf medium. According to the invention, the waste is turned into the valuable; exploitation of the resource of turf is reduced; and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and is a special cultivation substrate for economic fruit blueberries and a production process thereof, in particular to a special cultivation substrate for blueberries produced by utilizing vinegar grains through microbial fermentation and transformation and a production method thereof. Background technique [0002] Vinegar grains are the main by-products of vinegar making, accounting for about 70-80% of the raw materials for making vinegar. It is composed of rice husks fermented by vinegar making, a small amount of bran and rice wine dregs, with an organic matter content of about 90%, a nitrogen content of about 2.5%, and a total calcium, phosphorus, and potassium content of 0.6-0.75%. It is an organic waste with high cellulose and lignin content, high acidity at pH 4.5-5.5, and difficult to handle. Due to its large quantity, high fiber content and high acidity, it is easy to cause en...
