Problems solved by technology

At present, there are mainly two methods for the production of selenium-enriched strawberries in China. One is to spray selenite solution on the leaves, but this method has the disadvantages of large residual amount of inorganic selenium and low safety.
The second is to plant in natural selenium-rich areas. This method is difficult to quantify and control the selenium content, and there are geographical limitations, which is not conducive to large-scale standardized production

Embodiment 1

[0030] In the strawberry production base of Suzhou High-tech Zone, the selenium-enriched strawberry nutrient consisting of nano-selenium plant nutrient 1: organic fertilizer 1.5: microbial fertilizer 0.3 is selected. The selenium concentration is 5000 μg / g, and the ratio of 1:6 and moisture content is 10%. Stir the wet soil and apply it on April 20 at the rate of 10 kg per mu when plowing the strawberry base so that it is evenly distributed in the 0-15 cm layer. The selenium content and organic selenium ratio of mature organic selenium-rich strawberries were tested after harvest.

[0031] After testing, the average selenium content of strawberries after ripening is 10 micrograms / kg, reaching the selenium content standard of 10-50 micrograms / kg for selenium-rich fruits, but the proportion of selenium organic form selenium in strawberries is greater than 80%. The output of strawberries is 3200 jin / mu, which is 6.7% higher than that of 3000 jin / mu produced by ordinary methods.

Embodiment 2

[0033] In the strawberry production base in Suzhou High-tech Zone, a selenium-enriched strawberry nutrient consisting of nano-selenium plant nutrient 3: organic fertilizer 1: microbial fertilizer 0.2 was selected, and its total selenium concentration was 8000 micrograms / gram. Mix it with wet soil with a moisture content of 10% in a ratio of 1:6, and apply it on April 20 at the rate of 10 kg per mu when plowing the strawberry base, so that it is evenly distributed in the 0-15 cm layer. The selenium content and organic selenium ratio of mature organic selenium-rich strawberries were tested after harvest.

[0034] After testing, the average selenium content of strawberries after ripening is 40 micrograms / kg, reaching the selenium content standard of 10-50 micrograms / kg for selenium-rich fruits, but the proportion of selenium organic form selenium in strawberries is greater than 85%. The output of strawberries is 3300 jin / mu, which is 10% higher than the output of 3000 jin / mu of s...

Embodiment 3

[0036] In the strawberry production base in Suzhou High-tech Zone, select selenium-enriched strawberry nutrients composed of nano-selenium plant nutrients 4: organic fertilizer 1.2: microbial fertilizer 0.3, and its total selenium concentration is 10000 micrograms / gram. Mix it with wet soil with a moisture content of 10% in a ratio of 1:6, and apply it on April 20 at the rate of 10 kg per mu when plowing the strawberry base, so that it is evenly distributed in the 0-15 cm layer. The selenium content and organic selenium ratio of mature organic selenium-rich strawberries were tested after harvest.

[0037] After testing, the average selenium content of strawberries after ripening is 40 micrograms / kg, reaching the selenium content standard of 10-50 micrograms / kg for selenium-rich fruits, but the proportion of selenium organic form selenium in strawberries is greater than 80%. The output of strawberries is 3200 jin / mu, which is 6.7% higher than that of 3000 jin / mu produced by ord...

Abstract

The invention discloses a selenium-enriched strawberry nutrient, which is prepared by the following components in parts by weight: 1-4 parts of nano selenium plant nutrient, 0.5-1.5 part of organic fertilizer and 0.1-0.3 part of microorganism fertilizer, wherein the concentration of the selenium in the selenium-enriched strawberry nutrient is 5000-12000mg / kg. The method for producing selenium-enriched strawberries by using the selenium-enriched strawberry nutrient comprises the following steps: getting wet soil to mix with the selenium-enriched strawberry nutrient, and applying the mixture in a land in plowing or spreading the mixture along ditches in planting or after planting. The selenium-enriched strawberry produced by using the selenium-enriched strawberry nutrient has stable selenium content, and the ratio of selenium in organic form is above 80%.

Description

technical field [0001] The invention relates to a selenium-enriched strawberry nutrient and its preparation and application. Background technique [0002] Strawberry is the fruit of the Rosaceae plant strawberry. Originally produced in South America, Europe and other places, there are strawberry cultivation all over our country now, and there are also wild ones. It is picked when the fruit is ripe between June and July every year and used fresh. Carotene contained in strawberries is an important substance for the synthesis of vitamin A, which has the effect of improving eyesight and nourishing the liver; strawberries have a certain nourishing and regulating effect on gastrointestinal tract and anemia; , coronary heart disease also has a good curative effect; the tannic acid rich in strawberries can absorb and prevent the absorption of carcinogenic chemicals in the human body, and has anti-cancer effects; strawberries contain aspartic acid, which can naturally and peacefull...
