Special mineral adsorption fertilizer for improving content of blueberry anthocyanin and using method of fertilizer

Abstract

The invention discloses a special mineral adsorption fertilizer for improving content of blueberry anthocyanin and a using method of the fertilizer. An alkaline multi-element mineral fertilizer of a micro-porous structure serves as a selenium element carrier and a nutrition conditioner in acid soil to comprehensively promote absorption of beneficial elements. The selection requirements of the multi-element mineral fertilizer comprise nano-micron-order particles, loose state with micro-pore development and moisture and fertilizer retention ventilation functions with similar soil aggregate structures, wherein the content of effective K2O is more than or equal to 4 percent, the content of SiO2 is more than or equal to 20 percent, the content of CaO is more than or equal to 25 percent, and a certain amount of medium trace elements are contained. The preparation method comprises the following steps: adding a certain ratio of inorganic selenium and a proper amount of nitrogen fertilizer, performing proportion optimization combination according to the soil characteristics and blueberry varieties by using a quantum resonance (QRS) method, and preparing the special mineral adsorption fertilizer for blueberries.

Description

technical field [0001] The invention belongs to the research on the new technology of "blueberry green multi-nutrient element adsorption fertilizer", and specifically relates to a method for preparing and using a selenium-rich mineral adsorption fertilizer for increasing the content of blueberry anthocyanins. Background technique [0002] Blueberry belongs to Rhododendronaceae Vaccinium, also known as lingonberry. Blueberries are rich in anthocyanins, the main component of which is cyanidin-3-glucoside, which is a powerful antioxidant, and its antioxidant capacity is dozens of times that of vitamin C and vitamin E. The important function of anthocyanin pigments in blueberries is to promote the recombination of retinoids, thereby enhancing people's vision. According to the recommendations of American nutritionists, taking blueberry products every day can achieve the effect of eye health care. It is for this reason that the U.S. Department of Education has listed blueberries...

Problems solved by technology

[0008] However, the site requirement for blueberry growth is strong acidity, and the soil pH is 4.0-4.5. Selenium in acidic soil will be fixed by hexavalent iron and not absorbed by plants. As a result, neither the selenium in the soil nor the selenium supplemented by exogenous sources can be absorbed and utilized by blueberries. severe selenium deficiency

Moreover, most of the selenium element in the biological selenium fertilizers sold on the market is added to the fertilizer by sodium selenite, and sodium selenite is an inorganic selenium compound, and blueberry plants cannot absorb it normally after being applied to acidic soil.
