Abstract

The invention provides a method for cultivating wheat seedlings by using nitrogen stress nutrient solution. The method comprises the following steps of: repeatedly soaking wheat seeds in nitrogen stress solution until the wheat seeds sprout and grow to the height of between 5 and 20cm; and accumulating active oxygen in cells of the wheat seedlings by nitrogen stress to increase the quantity and activity of protective enzyme and enrich a polyphenolic substance. In order to prevent excessive active oxygen from damaging the cells, a method for alternating repeated and short-term nitrogen stress and nutrient solution cultivation is adopted to make the active oxygen slowly generated. By the method, more superoxide dismutase, catalase, peroxidase and the polyphenolic substance can be obtained, the yield of the wheat seedlings is improved, and new species of wheat seedlings rich in antioxidants are produced.

Description

(1) Technical field [0001] The invention relates to a method for cultivating wheat seedlings, in particular to a method for cultivating wheat seedlings using a nitrogen stress nutrient solution method. The invention belongs to the technical field of grain deep processing. (2) Background technology [0002] Wheat seedlings are rich in various minerals, essential amino acids, active enzymes, vitamins, chlorophyll, dietary fiber and other ingredients. They have the functions of preventing diabetes, stomach disease, asthma, constipation, and anti-aging. They are good dietary ingredients. At present, the research on wheat seedlings is as follows: [0003] Disclosed in 200710113410.7 is a technology that utilizes a nutrient solution that contains germanium dioxide to cultivate barley seedlings. It has the advantage of converting inorganic germanium into organic germanium that can be absorbed by the human body through the metabolism of barley seedlings. Germanium content in wheat...
