Problems solved by technology

Second, the Chinese dietary structure results in limited selenium intake
This scheme mainly uses selenium-containing flax cake as fertilizer, but it is difficult to realize large-scale industrial production of selenium-containing flax cake itself
[0009] However, the existing phytonutrients are used, and the active ingredients are difficult to store stably for a long time, that is, there is a defect that it is difficult to store for a long time

Abstract

The invention relates to a plant nutrient for planting selenium-enriched rice. The plant nutrient comprises nano selenium dioxide, sulfur-containing amino acid, bacillus subtilis and a Tween surfactant. According to the plant nutrient disclosed by the invention, inorganic selenium is converted into biological organic selenium through the photosynthesis of rice under the combined action of sulfur-containing amino acid and bacillus subtilis, and the biological organic selenium is naturally enriched in the rice, so that the selenium content of the rice is increased. Particularly, according to the plant nutrient disclosed by the invention, through the Tween surfactant formed on the surface of the nano selenium dioxide, the damage of the nano selenium dioxide to the activity of the bacillus subtilis is favorably inhibited, so that the storage stability of the plant nutrient is favorably improved, and the industrial production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a plant nutrient for planting selenium-enriched rice and its application. Background technique [0002] Selenium is an important trace element for humans and animals, and is an integral part of glutathione peroxidase that constitutes an indispensable part of the biological metabolism of higher animals. Selenium deficiency in the human body can lead to Keshan disease, Kaschin-Beck disease, etc., and selenium supplementation is beneficial to the exercise body to improve immunity. The International Selenium Society recommends a daily selenium intake of 60-400 μg for adults, and the Chinese Nutrition Society recommends a daily intake of 50-200 μg. Selenium is an essential trace element for humans and animals. It is an antioxidant that can relieve aging and eliminate a variety of harmful free radicals. Its synergistic effect with vitamin E is called the "g...
