Special blueberry fertilizer

Abstract

The invention discloses a special blueberry fertilizer which contains the following components in parts by weight: 25-50 parts of plant charcoal, 15-45 parts of red soil, 18-25 parts of rapeseed cakes, 2-3 parts of amino acid, 3-5 parts of potassium sulfate and 2-3 parts of diammonium hydrogen phosphate. The special blueberry fertilizer is capable of remarkably improving soil texture structures and soil environments, improving planting environments and meeting expected nutrients and soil environments, and in addition, is high in fertilizer efficiency, low in preparation cost, high in yield andorganic and environment-friendly.

Description

technical field [0001] The invention relates to a special fertilizer for blueberries. Background technique [0002] Blueberry is known as the "king of berries" for its unique fruit flavor and rich nutrition. Blueberries are rich in anthocyanins, low in sugar, low in fat, and have strong antioxidant capacity. Because of their unique nutritional value and health effects, blueberries are listed as one of the five health foods for human beings by the International Food and Agriculture Organization. At present, countries with large blueberry planting areas in the world include the United States, Chile, Canada, Poland, the Netherlands, and Japan. [0003] However, blueberry cultivation has strict requirements on climate, soil acidity and alkalinity and soil organic matter. In my country, blueberries are mainly planted in Northeast China, Inner Mongolia, Shandong, Anhui, Jiangsu, Zhejiang, Yunnan and Guizhou. Blueberries are shallow-rooted plants with slender and underdeveloped ...

Problems solved by technology

[0004] According to the characteristics of blueberry growth and planting environment, it has certain requirements for fertilizer nutrients and soil performance and environmental requirements. In order to meet the requirements of blueberry planting as far as possible, the existing blueberry planting has introduced fertilizers specially for blueberry planting, but most of them are It is prepared by adding ingredients, and its fertilizer effect and soil regulation cannot be taken into account. Moreover, the preparation process is relatively troublesome, and the production cost is relatively high. phenomenon; and in the vast areas of our country, the soil for cultivating blueberries needs to be improved, otherwise, not only cannot grow normally, but the survival rate of its cultivation is also very low. to improve the soil, but practice has proved that although this method is combined with special fertilizers for blueberry planting, on the one hand, it cannot well meet the balanced requirements of nutrients required for blueberry growth, and on the other hand, its soil environment cannot meet the requirements.
