Production method of organic selenium-rich fruit in selenium-poor area

Abstract

The invention discloses a production method of organic selenium-rich fruits in a selenium-poor area. The production method comprises the following specific steps: S1, selenium source selection: selecting an organic selenium-rich nutrient solution product which is easily absorbed by the leaf surfaces of fruit trees; s2, method selection: applying the diluted nutrient solution product to fruit trees for supplementing selenium; s3, field operation: according to the fruit tree type, the total pure selenium supplement amount is not less than 45 g / hectare, and the method is implemented in multiple times according to the proportion. According to the method, production of organic selenium-rich grapes, organic selenium-rich apples and organic selenium-rich cherries can be easily achieved, the organic selenium content standard of organic selenium-rich fruits is achieved, the method is not affected by soil selenium-containing conditions, and the method is implemented in season and effective in season and has good market value.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a method for producing organic selenium-rich fruits in selenium-poor areas. Background technique [0002] Selenium is one of the essential trace elements for the human body. It has the ability to resist oxidation and delay aging. However, selenium does not naturally exist in food. Most of the current selenium-enriched products come from areas rich in selenium in the soil. Selenium Intake is more related to the selenium content of the soil than to the diet. The soil in the United States and Canada contains more selenium, so many foods are rich in selenium. The selenium content in food is closely related to the selenium content in the soil environment. For example, the selenium content of crops produced in high-selenium areas in my country is as high as 4-8 mg / kg, while crops in low-selenium areas are 0.006 mg / kg, a difference of 1000 times. There is no perfect product...
