Planting method of selenium-rich peppers in southern acid red soil area

Abstract

The invention provides a planting method of selenium-rich peppers in a southern acid red soil area and relates to the technical field of planting of the selenium-rich peppers. The planting method of the selenium-rich peppers in the southern acid red soil area comprises the steps of land selection and land preparation: (1) seedling bed selection, wherein a land parcel which faces south and is closeto a water source is selected for a seedling bed, solanaceae and other sib crops are not planted on the land parcel, deep digging and soil roasting are conducted on the seedling bed in hot summer days, the surface of the seedling bed is splashed with a layer of human and livestock excrement, and the excrement is air-dried and then covered with a layer of a thin film; (2) land preparation, whereina land parcel with flat terrain, good drainage and convenient irrigation and drainage is selected as a planting land, winter ploughing is conducted in the first year, frozen earth is idle, so that the soil is improved, and plowing is conducted with the depth of 12-15 centimeters before field planting. Through application of a selenium-containing fertilizer and spraying of a selenium-rich nutrientsolution in the pepper growth period, the content of selenium in fruits produced by pepper plants is obviously increased, and when people eat the peppers in the daily life, the content of the selenium taken from the peppers is increased, so that the peppers are more beneficial to the physical health of people.

Description

technical field [0001] The invention relates to the technical field of planting selenium-enriched peppers, in particular to a method for planting selenium-enriched peppers in the southern acidic red soil region. Background technique [0002] The role of selenium is relatively broad, but there are two main principles: first, the composition of antioxidant enzymes in the body can protect the cell membrane from oxidative damage and maintain its permeability; second, selenium-P protein has the ability to chelate heavy metals and other poisons, reducing the toxic effect of poisons. Selenium is called the "king of anti-cancer" among trace elements in the human body by scientists. Research in the scientific community has found that the level of blood selenium is closely related to the occurrence of cancer. [0003] The peppers we eat in daily life are generally conical or oblong fruits, green when immature, and bright red, green or purple when mature, with red being the most common...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for planting selenium-enriched peppers in southern acidic red soil areas, which solves the problem that in recent years, along with everyone's awareness of healthy living, organic foods rich in selenium, especially vegetables Melons and fruits are widely favored by everyone, but the content of selenium in peppers grown in acidic red soil areas in the south is generally relatively low, and people cannot get enough selenium in peppers
