Blueberry culture medium and preparation method thereof

Abstract

The embodiment of the invention discloses a blueberry culture medium and a preparation method thereof. The blueberry culture medium disclosed by the invention comprises the following added components in original soil per cubic meter: 3.5-4.5kg of thoroughly decomposed and fermented vinegar residues, 4.0-5.0kg of organic fillers and 1.0-1.5kg of organic fertilizers. The method for preparing the blueberry culture medium disclosed by the invention comprises the following steps: fermenting and thoroughly decomposing the vinegar residues; and fully mixing the components of the blueberry culture medium disclosed by the invention. The waste vinegar residues are turned into valuable materials, the pH value of the original soil is reduced to be 4.5-5.0, micro matters and mineral elements needed by blueberry growth can be provided, and the nutrient status and water distribution condition of the culture medium can be improved; and therefore, the blueberry survival rate is 92-96 percent, the flower abortion rate is less than 8 percent, and the average yield reaches 500-550g per plant.

Description

technical field [0001] The invention belongs to the field of blueberry cultivation, and in particular relates to a blueberry cultivation substrate and a preparation method thereof. Background technique [0002] Blueberry (Blueberry), means the meaning of blue berry. One is a low shrub, wild with short feet, small particles, but high anthocyanin content; the second is artificially cultivated blueberries, which can grow to 240cm high, with larger fruits, more water, and relatively high anthocyanin content Low. There are more than 400 species of Vaccinium distributed all over the world. It originates in and is mainly produced in the United States and is also known as American blueberry. my country mainly produces in Daxing'an Mountains and Xiaoxing'an Mountains forest area, especially the central part of Daxing'an Mountains, and it is all pure wild. It has only been successfully domesticated and cultivated in recent years. Blueberry fruit is rich in nutrients. It not only h...

Problems solved by technology

The traditional way to reduce the soil pH value is to apply sulfur. In organic cultivation, sulfur has the effect of killing insects and bacteria, but the application of sulfur will affect the soil biological status; although the pH value gradually decreases with the increase of sulfur application rate, the salt content in the soil It will also increase accordingly, and the increase in soil salinity will affect the balance of hormones in the plant, which will lead to the imbalance of the nutritional status of the whole plant; The acidic fertilizer aluminum sulfate is used to reduce the pH value of the soil. The applied aluminum sulfate has a certain toxic effect on the blueberry root system.

Although the current blueberry planting can choose regions with suitable soil acidity, the geographical limitations also limit the yield and edible value of blueberries.

Therefore, the modification method of blueberry cultivation substrate is still a difficult point that perplexes blueberry cultivation
