Embodiment Construction

[0013] A method for increasing the content of chromium and selenium in agricultural products, including a method for producing a chromium-rich and selenium-rich organic fertilizer solution and a method for fertilizing crops. The organic fertilizer liquid is mixed according to a certain proportion, and after being fully stirred, it is fermented at a temperature of 20-25°C for a certain period of time to obtain a chromium-rich selenium-rich organic fertilizer liquid. The method of fertilizing crops is: add a certain proportion of chromium-rich selenium-rich organic fertilizer liquid After diluting with water, spray evenly on the leaves of the crops in different growth periods according to different types of crops. After implementation, the content of organic chromium and organic selenium in agricultural products can be increased by 10-15 times, and the chromium content of obtained agricultural products can be 0.21-0.52vg ; Selenium content 0.15-0.42vg.

Abstract

The invention discloses a method for improving the content of chromium and selenium of farm products, which comprises a method for producing a selenium-rich and chromium-rich organic fertilizer solution and a method for fertilizing crops, wherein a process of the method for producing the selenium-rich and chromium-rich organic fertilizer solution comprises the steps of mixing chromium glycine, sodium selenite and an organic fertilizer solution according to certain proportion, fully stirring the mixture, and then fermenting the mixture for certain time at the temperature of between 20 and 25 DEG C to obtain the selenium-rich and chromium-rich organic fertilizer solution; and the method for fertilizing the crops comprises the steps of diluting the selenium-rich and chromium-rich organic fertilizer solution by adding water with certain proportion, and then evenly spraying the diluted selenium-rich and chromium-rich organic fertilizer solution on leaves of the crops at different growth periods of the crops according to different crop varieties. After the method is implemented, the content of organic chromium and organic selenium of the farm products can be improved by between 10 and 15 times, the content of the chromium of the obtained farm products is between 0.21 and 0.52vg, and the content of the selenium is between 0.15 and 0.42vg. The method for improving the content of the chromium and the selenium of the farm products has simple and convenient operations, and is economical and practical.

Description

technical field [0001] The invention relates to a method for producing agricultural products, in particular to a method for increasing the content of chromium and selenium in agricultural products. Background technique [0002] Drugs containing chromium and selenium can enhance human immunity, prevent tumors, and have certain preventive and therapeutic effects on middle-aged and elderly diabetes, hypertension, and hyperlipidemia. However, taking chromium-containing and selenium-containing drugs may also bring different degrees of side effects or safety hazards to the human body. If people are allowed to eat chromium-rich and selenium-rich agricultural products, it can not only enhance human immunity, prevent tumors, prevent and treat middle-aged and elderly diabetes, high blood pressure, and hyperlipidemia, but also overcome the effects of taking chromium- and selenium-containing drugs to the human body. side effects and safety hazards. Therefore, researching a method for ...
