Problems solved by technology

The common disadvantages of both are: need to carry out selenium nutrition fortification many times, including inorganic selenium soaking, root application, spraying, etc., the operation is cumbersome, and it needs to input a large labor cost; a large amount of selenium is used in the production process, and wheat is harmful to the human body. The absorption and utilization of selenium is low, resulting in the waste of selenium resources. A large amount of selenium flows into the farmland ecosystem, which is easy to cause selenium pollution; there are steps of spraying inorganic selenium leaves in the production process, and plant leaves are not the main absorption organs. Limited, inorganic selenium is highly toxic, and residual inorganic selenium poses a greater safety hazard

Embodiment 1

[0038] In a wheat planting field, before wheat sowing, four wheat planting fields were selected, and the nano-selenium plant nutrient was fully mixed with high-quality organic compound fertilizer for wheat base fertilizer according to the application rate of 1, 2, 5, and 7 kg / mu respectively. Sprinkle evenly into the wheat field and lightly turn the wheat field. Afterwards, wheat sowing and production management are carried out, and the selenium content of wheat in each field is detected at the final harvest.

Embodiment 2

[0042] In a certain wheat planting field, when wheat is sown, four wheat planting fields are selected, and the nano-selenium plant nutrient is fully mixed with the granular compound fertilizer for wheat base fertilizer according to the application rate of 1, 2, 5, and 7 kg / mu respectively. The fertilizer seeder is sown into the field together with the seeds. Afterwards, routine wheat production management was carried out, and the selenium content of wheat in each field was detected at the final harvest.

Embodiment 3

[0046] In a wheat planting field, when the wheat seedlings emerged for one week, four wheat planting fields were selected, and the nano-selenium plant nutrient was mixed with the high-quality organic compound fertilizer for wheat according to the application rate of 1, 2, 6, and 8 kg / mu respectively. Sprinkle evenly into the wheat field. Afterwards, routine wheat production management was carried out, and the selenium content of wheat in each field was detected at the final harvest.

Abstract

The invention discloses a wheat rich in organic selenium and a production method thereof. The wheat rich in organic selenium has the total selenium content of 50-300 mu g / kg and the ratio of organic selenium in the wheat is not less than 80%. The method is realized by cultivating according to a normal wheat planting method, and the method is characterized by also comprising the step of: applying a nano selenium plant nutritional agent at one or more stages of stage before sowing, sowing stage, seedling emergence stage, winter dormancy stage, regreening stage, jointing stage, booting stage and irrigation initial stage in the wheat growth cycle. According to the wheat rich in organic selenium disclosed by the invention, the organic selenium content is stable and controllable, the ratio of organic selenium is not less than 80%, and organic selenium is safer in state and better in absorption and utilization.

Description

technical field [0001] The invention belongs to the technical field of wheat cultivation, and in particular relates to a production method of selenium-enriched wheat. technical background [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. The Chinese Nutrition Society recommends a daily selenium intake of 50-250 μg, but the average daily selenium intake of Chinese adults is only about 36 μg. Therefore, selenium malnutrition is common in our country. Severe selenium deficiency can lead to endemic diseases such as Kaschin-Beck disease and Keshan disease. The data released by WHO also shows that more than 40 countries in the world belong to low selenium or selenium deficient areas. The source of selenium in the human body mainly depends on dietary intake. Selenium-enriched agricultural by-products are a...
