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 b...

Embodiment Construction

[0037] Case 1: No. 1 blueberry experimental field.

[0038] Soil characteristics: pH5.5-5.8, clay, organic matter 1.56%, alkaline nitrogen 127.07mg / kg, available phosphorus 7.85mg / kg, available potassium 138.66mg / kg. The plant height of a single blueberry is 60cm, the crown width is 60cm, and there are 300 plants / mu.

[0039] Fertilizer scheme: The base fertilizer is 1-2 ammonium sulfate per plant and 1-2 catties of cake fertilizer. During the fruiting period, the special mineral adsorption fertilizer obtained in this embodiment was topdressed, and the special mineral adsorption fertilizer of the present embodiment applied per mu was obtained by mixing 40 jin of microporous multi-element mineral fertilizers on the market with 4g sodium selenite. In this experiment, multi-element mineral fertilizer was used as the control group.

[0040] The main components of the multi-element mineral fertilizer: Ca 4.84mg / g, Si 3.88mg / g, Mg 1.44mg / g, K 0.75mg / g, P 0.49mg / g, Fe 0.62mg / g, Zn ...

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...
