Problems solved by technology

[0006] At present, the production method of selenium-enriched millet is mainly to spray inorganic selenium solution on the leaves of millet during the growth period of millet. After repeated spraying, the selenium content in millet can reach the expected target. The disadvantage is that the conversion rate of inorganic selenium is low , the residue is serious, long-term consumption of the millet obtained in this way has the risk of causing selenium poisoning in the human body; the second is that the technical method is simple and extensive, and needs to be sprayed multiple times, and it needs to be sprayed again after encountering bad weather, resulting in a waste of manpower and financial resources At the same time, there is a risk of polluting the environment

Embodiment 1

[0026] Selected from a millet planting field in Northwest China, plowed at a depth of 20 cm, and applied 1000 kg of farmyard manure as a base fertilizer per mu at one time, and applied it in early spring, and mixed selenium-containing materials with conventional fertilizers in a ratio of 1:2 After uniformity, apply it to the field at one time before the millet filling period, and apply 20 kilograms per mu. Among them, the selenium content of the selenium-containing material used is 300 mg / kg. After fertilization, it needs to be irrigated in time in case of long-term drought, and the rest of the field management is in accordance with normal management. conduct. After the millet is harvested, samples are taken to detect the selenium content in the millet.

[0027] After testing, the average selenium content in millet is 190ug / kg.

Embodiment 2

[0029] Select a millet planting field in Northwest China, plow 25cm deep, and apply 1000 kg of farmyard manure as base fertilizer per mu at one time, and apply it in early spring, mix selenium-containing materials with conventional fertilizers in a ratio of 1:3 After uniformity, apply it to the field at one time before the millet filling period, and apply 30 kg per mu. Among them, the selenium content of the selenium-containing material used is 800mg / kg. If there is a long-term drought after fertilization, it needs to be irrigated in time, and the rest of the field management is in accordance with normal management. conduct. After the millet is harvested, samples are taken to detect the selenium content in the millet.

[0030] After testing, the average selenium content in millet is 320ug / kg.

Embodiment 3

[0032] Select a millet planting field in Northwest China, plow 30cm deep, and apply 1000 kg of farmyard manure as base fertilizer per mu at one time, and apply it in early spring, mix selenium-containing materials with conventional fertilizers in a ratio of 1:5 After uniformity, apply it to the field at one time before the millet filling period, and apply 20 kg per mu. Among them, the selenium content of the selenium-containing material used is 1000 mg / kg. After fertilization, in case of long-term drought, it needs to be irrigated in time, and the rest of the field management is in accordance with normal management. conduct. After the millet is harvested, samples are taken to detect the selenium content in the millet.

[0033] After testing, the average selenium content in millet is 280ug / kg.

Abstract

The invention discloses a method for producing selenium-enriched millet. The method comprises the following steps: (1) preparing selenium-containing fertilizer, namely uniformly mixing a selenium-containing material with the conventional fertilizer in proportion; (2) carrying out soil preparation, namely selecting high-quality and fertile land, deeply ploughing for 20-40cm, and applying farmyard manure as base fertilizer according to a ratio of 1000kg per Mu at one time; (3) carrying out topdressing, namely uniformly spreading the mixed fertilizer obtained in the step (1) over a millet field at one time in a jointing-booting stage of millet; (4) carrying out field management, namely irrigating timely if meeting long-term drought after fertilization; and (5) harvesting, namely when all the grains turn yellow and are hardened, timely harvesting, airing, and then threshing, so that the selenium-enriched millet is obtained. The method disclosed by the invention has the advantages that the selenium-containing fertilizer is applied to the jointing-booting stage of the millet at one time, so that the millet absorbs selenium by virtue of roots, the absorbed selenium is converted and synthesized into organic selenium, and a selenium form in the millet is safer and more effective; and the operation is simple and practicable, the selenium content of the millet is effectively improved, and the selenium nutrition level of a human body taking a millet product as staple food can be obviously improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of agricultural technology, in particular to a production method of selenium-enriched millet. [0003] 【Background technique】 [0004] The nutritional value of millet is very high, containing 9.2%-14.7% of protein, 3.0%-4.6% of fat and vitamins. It also contains carotene that is not contained in general grains. The content of vitamin B1 ranks first among all grains. The salt content is also higher than that of rice; it is also rich in fat, 7.8 times that of rice, and mainly unsaturated fatty acids; in addition to rich iron, millet also has protein, complex vitamin B, calcium, potassium, fiber, etc.; millet The quality of protein in wheat is often better than that of wheat, rice and corn. Millet has the functions of invigorating the spleen and stomach, nourishing deficiency, harmonizing kidneys, clearing heat and quenching thirst, invigorating the stomach and dehumidification, and harmonizing the stomach for s...
