Problems solved by technology

[0006] 200610072921.4 discloses a chromium-rich, high-quality triticale specific germplasm cultivation method. The advantage of this method is that it organically combines methods such as conventional breeding, haploid breeding, slow radiation, and distant hybridization immature embryo rescue. Improvements were made to breed new germplasm of triticale with high yield, wide adaptability, rich in organic chromium, suitable for diabetics, and genetically stable traits, but this method cannot increase the content of organic selenium in triticale
[0013] At present, since the yield of ordinary common wheat is higher than that of purple wheat, most of the domestic published patent documents related to the enrichment of trace elements use common wheat as the research object, and there is no patent document published on purple wheat selenium enrichment technology.

Abstract

The invention relates to a method for producing a selenium-rich purple wheat by using a biological selenium-rich fertilizer and a whole course dynamic gradient selenium-rich method, which belongs to the crops cultivation technical field. The method is characterized in that the biological selenium-rich fertilizer is produced, and is used to prepare a selenium-rich fertilizer mother liquor, and then the selenium-rich fertilizer mother liquor is diluted to a selenium-containing fertilizer liquid with different selenium concentrations, and is affected on soil, purple wheat seeds and whole purple wheat at different growth periods. The wheat seeds enable full enrichment on the selenium element, according to the growth characteristics of the purple wheat, the selenium-containing fertilizer liquid with different gradients is used for fitting with the purple wheat growth rules during the whole growth process of the purple wheat, thereby the exogenous inorganic selenium can be conversed to plant endogenous organic selenium with high efficiency. By detecting, the selenium content of the purple wheat product provided in the invention is 0.18-0.28mg / kg, wherein the organic selenium content is 0.16-0.25mg / kg, compared with the purple wheat product which is sprayed by a single selenium-containing fertilizer liquid c in the whole process, the selenium content multiple can reach 5-7 times.

Description

(1) Technical field [0001] The invention relates to a method for cultivating selenium-enriched crops, in particular to a biological selenium-enriched fertilizer and a whole-process dynamic gradient selenium-enriched purple wheat production method thereof. It belongs to the technical field of crop cultivation. (2) Background technology [0002] Purple wheat refers to the wheat whose seed coat or aleurone layer is purple in color, and is mainly composed of anthocyanins. Anthocyanins are a class of water-soluble pigments widely present in plants and belong to flavonoid compounds. As a natural food coloring, it has various health functions such as anti-oxidation, blood vessel protection, ascorbic acid, cancer prevention, etc. It can be directly used in food, medicine, beauty and other industries. Therefore, anthocyanins are important bioactive substances of purple wheat, and purple wheat has become one of the hot spots in the development and research of functional foods. In a...
