Problems solved by technology

However, the environmental pollution caused by saponin wastewater is also a bottleneck problem in saponin industrial production.
Saponin wastewater has the characteristics of large chroma, high concentration of organic pollutants, high acidity, and high temperature. It is difficult to treat and causes great pollution to the surrounding water and soil.

Embodiment 1

[0029] The preparation method of the acidic organic fertilizer for planting blueberries comprises the steps:

[0030] The first step, the isolation and cultivation of acidic high-efficiency complex bacteria

[0031] Step 1.1 Collect humus soil samples from acidic soil, add water according to the ratio of solid to liquid 1:4 to make humus soil extract, obtain the extract after filtering, and use saponin wastewater with a pH value of 1 to 3 to adjust the leaching solution. The pH value of the extract is 3.5-4.8, and after adjustment, keep it for 1 minute to obtain an acidified extract, collect the root soil of the blueberry, separate the heather bacteria in the mycorrhiza, and then add the heather bacteria to the extract The bacteria isolated from the acidic soil are compounded to obtain the mixed bacteria extract;

[0032] Step 1.2 Inoculate the mixed bacterial extract obtained in step 1.1 into potato glucose liquid culture medium, and divide it into 3 parts, and place the abo...

Abstract

The invention discloses a blueberry plantation acidic organic fertilizer comprising the following components by mass: 20%-40% of an acidic compound bacteria culture, 15%-20% of saponin residue, 15%-35% of pine needle, 10%-15% of sawdust, and balance of straw; the sum of the content of all the components is 100%. The present invention also discloses a preparation method of the acidic organic fertilizer, the preparation method includes acidic compound bacteria separation culture, composting, construction of a heap, inoculation, compost maturity, dry-making, packaging and other steps; the blueberry plantation acidic organic fertilizer has the many advantages of keeping soil porosity, increasing organic matters, and maintaining soil acidity; according to the preparation method of the blueberry plantation acidic organic fertilizer, and the characteristics of strong saponin wastewater acidity and poor biodegradability can be used for development of the a blueberry plantation acidic organic fertilizer, the problem of difficult recycling of saponin wastewater can be solved, blueberry plantation needed acidic organic fertilizer can be provided, the method is easy to implement, and the used raw materials are easy to obtain.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to an acidic organic fertilizer for planting blueberries, and also relates to a preparation method of the organic fertilizer. Background technique [0002] Blueberry is a fruit with very high nutritional value and economic value. It is rich in nutrients such as vitamins, proteins and minerals. Among them, the unique and precious anthocyanin pigment in blueberry is more than 20 times that of other fruits. The reputation of the king of green vegetables and fruits. However, blueberry growth and development conditions are harsh, and the development area is limited. There are two biggest constraints. The first is the requirement of acidic soil conditions, that is, the soil pH value is 4.2 to 5.5; the second is the climatic conditions, that is, the annual rainfall is above 800mm and the low temperature below 7.2°C is above 500h. [0003] There are very few ar...
