Planting method of selenium-enriched maca

Abstract

The invention discloses a planting method of selenium-enriched maca. The planting method comprises the steps of site selecting, land preparing, seed treating, sowing and seedling raising, seedling transplanting, later fertilizer managing, field managing and selenium-enriched maca harvesting. Before seedlings are transplanted, selenium-enriched base fertilizer is applied to a maca planting field; when maca leaf surfaces completely spread, selenium-enriched compound fertilizer is applied to the maca planting field, therefore, complex-state selenium from soil and the leaf surfaces are absorbed through maca root systems and the leaf surfaces and participate in synthesis of protein in maca roots and stems, and ionic-state selenium is stored in the maca roots and stems in the form of selenoprotein; raw materials of the fertilizer are mostly prepared from plants, therefore, no secondary pollution can be caused, and environmental protection is facilitated; the total selenium content of the harvested selenium-enriched maca is more than or equal to 0.15 mg / kg and reaches the selenium-enriched standard of the state. The selenium-enriched maca can be used as initial raw materials of food, functional food, health care products and drugs or directly used and is widely applied to the massive health category of a human body.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for planting selenium-enriched maca. Background technique [0002] Maca, scientific name: LepidiummeyeniiWalp., Spanish: Maca, is a cruciferous plant native to South America, edible, is a pure natural food, rich in nutrients, known as "South American ginseng"; Maca It is native to high-altitude mountainous areas and is suitable for growth in high-altitude, low-latitude, high temperature difference between day and night, slightly acidic sandy soil, and sunny land; Maca is distributed in the Andes Mountains of South America, artificially planted in central and southern Peru, Yunnan and China Xinjiang and other regions also have large areas of land suitable for planting. [0003] The chemical composition of maca dry root includes: more than 10% protein; 59% carbohydrate; 8.5% fiber; rich in zinc, calcium, iron, titanium, rubidium, potassium, sodium, copper, manga...

Problems solved by technology

Selenium-enriched maca adopts the theory of "medicine and food from the same source", organically combines the selenium element necessary for the human body every day with natural green maca, and truly achieves the same food and supplements; selenium-enriched maca is a kind of anti-fatigue food for people Specialty food, the use of organic planting can reduce its pollution from nature and reduce the harm of harmful residues to people's health; in the prior art, Maca planting has no selenium or the content of selenium is lower than the national standard, and the technical content of the product is low, and Maca is nutritious The value needs to be improved; therefore, it is particularly important to establish a complete set of selenium-enriched maca planting methods from site selection, whole field, seed treatment, sowing and seedling raising, seedlings, transplanting, later fertilizer management, field management to harvest
