Planting method of selenium-rich oranges

Abstract

The invention provides a planting method of selenium-rich oranges. On the basis of a normal orange cultivation method, the planting method also comprises steps as follows: a selenium-rich nutritional agent is taken, strip-shaped fertilization ditches are formed in two opposite sides of the water drip edge of the crowns of orange trees in the flowering period during growth and cultivation of the oranges, and the selenium-rich nutritional agent and soil are blended uniformly and applied to the fertilization ditches; the selenium-rich nutritional agent and manure and urine of human beings or animals are taken and broadcast around the tree before raining or after raining in the rainy seasons of spring and summer; the selenium-rich nutritional agent, a plant surfactant and clear water are mixed and sprayed in the fruit bearing time during growth and cultivation of the oranges. After the selenium-rich nutritional agent is used, the edible rate of oranges of each mu can reach 85% or above, the juice rate reaches 50%-60%, the content of vitamin C of every 100 ml is 60-70 ml, and the content of selenium in each kilogram of orange fruits is larger than 23 mu g and is 10 times or higher that of ordinary oranges.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for planting selenium-enriched oranges. Background technique [0002] Selenium is a chemical element with the chemical symbol Se. It is a nutrient element beneficial to plants and an essential trace element for the human body. Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. Selenium, vitamin E, allicin, linoleic acid, germanium, zinc and other nutrients have synergistic antioxidant effects and increase antioxidant activity. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals. Selenium deficiency in the human bod...

Problems solved by technology

At present, in the planting process, in order to increase the yield, the growers use a large amount of chemical fertilizers and pesticides, resulting in serious damage to the soil, insufficient nutrients and poor taste of oranges, which cannot realize the value of nutrition and health care.
