Abstract

The invention provides a cultivation method for selenium-rich and / or chromium-rich mesembryanthemum crystallinum, which relates to the technical field of facility agriculture. The method comprises thefollowing steps: a mesembryanthemum crystallinum seedling is planted in a cultivation tank, wherein the cultivation tank comprises a cultivation tank frame, a water-proof film, a drip irrigation belt, non-woven fabric, a substrate, a planting plate and a reflective mulching film arranged sequentially from bottom to top, the water-proof film is arranged on the ground and located on the same horizontal layer as the cultivation tank frame, and the substrate comprises a chromium-containing organic compound and / or a selenium-containing substance; during the seedling growth period, water and a fertilizer are applied through the drip irrigation belt, the water and the fertilizer are applied once every 3 to 12 days, and the selenium and chromium contents in the mesembryanthemum crystallinum are improved by 200 to 500 times. Thus, the problem of insufficient selenium and chromium in a human body can be effectively solved, and annual supply can also be achieved.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to a cultivation method of selenium-rich and / or chromium-rich ice vegetables. Background technique [0002] People who pursue quality life in modern society not only pay more and more attention to the green and healthy diet, but also the health functions of fruits and vegetables are gradually favored by people. Iced vegetables themselves contain a variety of amino acids, flavonoids and other nutrients that are rare in other vegetables, which can slow down the aging speed of brain cells and strengthen the function of brain cells; its sour taste is natural malic acid, rich in sodium, potassium, carotene The surface of iced vegetables is covered with a layer of "ice crystal" bubble-shaped cells, which are rich in natural plant salts, which are good for patients with high blood pressure, diabetes, and hyperlipidemia. Iced vegetables are undoubtedly the first-cla...
