Efficient selenium-enriching method for salicornia europaea

Abstract

The present invention discloses an efficient selenium-enriching method for salicornia europaea and belongs to the technical field of selenium-enriching agricultural products. A D-saturation optimization design is used, salicornia europaea grown on the ground is used as a cultivation plant, and a selenium-enriching treatment in the growing period is conducted. During the treatment process, in the peak season in May and June, the spraying selenium-enriching treatment is conducted in 4-5 times with an interval of 7 days each time, a spraying solution is a malt selenium solution, pH is 6.5-7.0, concentration is 5,000-10,000 [mu]g/L, spraying amount is 60-80 mL/m<2>, and organic selenium content in the fresh salicornia europaea reaches 10 [mu]g/kg or more. Advantages are as follows: aiming at acharacteristic that the salicornia europaea is very high in extreme tolerance spraying concentration, the spraying solution with relatively high concentration and suitable pH is used, the multiple-time selenium-enriching optimization method is conducted, so that the content of organic selenium is significantly increased in a short period of time. The efficient selenium-enriching method for the salicornia europaea is obviously shortened in operation cycle and reduced in operation cost.

Description

[0001] Field [0002] The invention belongs to the technical field of selenium enrichment of agricultural products. Background technique [0003] Selenium (Se) is a trace element with a molecular weight of 78.96. It is located in the VIA group of the periodic table of chemical elements. Its chemical properties are similar to those of the same group of sulfur. The current opinion generally believes that the appropriate amount of selenium in the diet plays an important role in maintaining health. First of all, selenium plays an irreplaceable role in improving the body's antioxidant capacity. Selenium can participate in the catalytic reaction of a variety of enzymes in the human body and regulate the absorption and consumption of vitamins. In addition, selenium also has important physiological functions such as anti-cancer, liver protection, binding of heavy metals, and prevention and treatment of cardiovascular diseases. Selenium is the most important part of the human body. Antiox...

According to testing by authoritative organizations, 100g of sea asparagus tender stems contains 29.17mg of carotene, which is nearly 40 times higher than that of ordinary vegetables; 14.3mg of vitamin E; 112.7mg of iodine. Human health; rich in essential amino acids, dietary fiber and trace elements such as calcium, iron, zinc, selenium, phosphorus and other minerals, also contains natural plant alkaloids and flavonoids, but the content of selenium is not as high as the selenium-rich vegetable sea asparagus The standard of organic selenium content 2.8μg / kg
