Embodiment Construction

[0008] Selenium 0.01-0.05, nitrogen 0.8-1.3, potassium 1.6-3.2, phosphorus 1.2-2.2, molybdenum 0.1-0.3 and water 1000 are mixed to prepare a nutrient solution.

[0009] The above ingredients are mixed to prepare a nutrient solution. The roots of the guava were sprayed once a week before and after flowering, and sprayed three times on the leaf surface during the fruit expansion period, with an interval of 7 days between each spraying.

[0010] Then, the selenium-enriched guava is processed in the following steps: selecting fruit → washing → squeezing the juice → filtering → bottling to become selenium-enriched guava juice.

[0011] The present invention sprays the selenium-enriched nutrient solution during the growth period of the guava to increase the organic selenium content to the required content. After the guava is processed into juice, the selenium content is as high as 4.1 mg / kg, which is formulated according to the product standard quality , So that guava juice products alway...

Abstract

A planting method of selenium-rich Psidium guajava mainly includes mixing selenium, nitrogen, potassium, phosphorus, and molybdenum with water in a certain ratio to obtain a nutrient solution, and spraying the nutrient solution in the proper blossoming and fruiting stages of Psidium guajava such that mature fruits of Psidium guajava are rich in selenium. Inorganic selenium and chromium are absorbed by Psidium guajava and converted into organic selenium, no toxicity occurs, and high disease resistance, yield increase and quality improvement are imparted to the plants of Psidium guajava; fruit juice of Psidium guajava made with the fruits of Psidium guajava has a selenium content of up to 4.1 mg/kg, which is stable, and has rich nutrition; guava juice or fruit juice becomes a real nutrient health food; new channels are created for fruit farmers to plant Psidium guajava, and the income is increased.

Description

Technical field [0001] The invention relates to a cultivation method of selenium-enriched guava. Background technique [0002] Selenium-enriched foods have been recognized and gradually popularized for consumption, and bring people health and stay away from "three high diseases". The development of selenium-rich organic health agricultural products is the only way for the development of modern agriculture to add value. According to public reports, selenium is called "the king of health care" by scientists. It acts synergistically with vitamin E in the body to protect cell membranes and prevent the oxidation of unsaturated fatty acids, so selenium has an antioxidant effect. Selenium also enhances immunity: organic selenium can scavenge free radicals in the body, eliminate toxins in the body, resist oxidation, can effectively suppress the production of lipid peroxides, prevent blood clots, remove cholesterol, and enhance human immune function. [0003] At present, the content of se...
