Special concentrated water-soluble fertilizer for blueberries as well as preparation method and application method of special concentrated water-soluble fertilizer

Abstract

The invention provides a special concentrated water-soluble fertilizer for blueberries as well as a preparation method and an application method of the special concentrated water-soluble fertilizer, wherein the special concentrated water-soluble fertilizer is prepared from the following components: a macroelement nutrient solution A and a trace element nutrient solution B, wherein the macroelementnutrient solution A comprises 1.2-4.80 mol / L of ammonium sulfate, 0.6-2.40 mol / L of calcium nitrate tetrahydrate, 0.4-1.60 mol / L of potassium nitrate, 0.20-0.80 mol / L of magnesium sulfate and 0.20-0.80 mol / L of monopotassium phosphate; and the trace element nutrient solution B comprises 0.20 mol / L-0.60 mol / L of manganese sulfate, 0.10 mol / L-0.50 mol / L of boric acid, 0.005 mol / L-0.015 mol / L of copper sulfate, 0.05 mol / L-0.15 mol / L of zinc sulfate, 0.005 mol / L-0.015 mol / L of sodium molybdate, 0.10 mol / L-0.50 mol / L of ferrous sulfate and 0.10 mol / L-0.50 mol / L of ethylene diamine tetraacetic acid. According to the method, the requirements of blueberries for nutrient elements and the physical and chemical properties of soil are comprehensively considered, and the pH value and porosity of soilimprovement in the production process can be continuously stabilized. Compared with a traditional fertilization mode, the fertilizer investment is small, the absorption and utilization rate is high, soil protection is better facilitated, and sustainable production of blueberries is achieved.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizers, in particular to a special concentrated water-soluble fertilizer for blueberries, a preparation method and an application method thereof. Background technique [0002] Blueberry is a perennial shrub belonging to the Rhododendronaceae Vaccinium genus. The fruit is blue in color and covered with a layer of white fruit powder. The flesh is delicate, the fruit tastes sweet and sour, unique in flavor and rich in nutrition. Its fresh fruit is rich in nutrients such as carbohydrates, organic acids, proteins, Vc, anthocyanins, and flavonoids. Among them, blueberry anthocyanins are honored as "the No. 1 antioxidant" and can protect cells from oxidation. Delay aging; also promote the regeneration of rhodopsin in the retina, eliminate eye fatigue, enhance vision, prevent severe myopia and retinal detachment and other problems; in addition, it can lower blood pressure, lower cholesterol, a...

AI Technical Summary

Problems solved by technology

However, the water-soluble fertilizers in the prior art are ready-to-use, and the preparation is inconvenient, and a separate large container is required for configuration, which has defects in production.

The specific ratio of each element is not clear in the prior art, and it is easy to affect the growth of blueberries due to improper preparation of the ratio of each element during the preparation process.

The existing technology is suitable for transplanting blueberry plants that have entered the full fruit period for 3 years, but not for blueberry seedlings that have just been transplanted.
