Embodiment 1

[0034] When sowing corn, 0.05 kilograms of nano-selenium plant nutrients (produced by Suzhou Selenium Valley Science and Technology Co., Ltd., model XGP001B) are evenly mixed with the granular fertilizer in the base fertilizer. The mixing method is to mix the nano-selenium plant nutrients with a small amount (such as 1 kg) granular fertilizers are mixed evenly, and then enlarged step by step and mixed evenly, the amount of selenium fertilizer in the mixed fertilizer accounts for more than 10% of the mixture ratio, and the following fertilizer mixing methods are all like this. Then corn seeds and mixed fertilizer are sown into the field at the same time to realize simultaneous sowing of seed and fertilizer.

[0035] After the corn seedlings are established and before jointing, topdressing is generally carried out when 5-6 leaves of the plant are visible. At this time, the topdressing fertilizer is mainly nitrogen fertilizer (such as urea). Evenly mix 0.1 kg of nano-selenium pla...

Embodiment 2

[0040] When sowing corn, 1 kilogram of nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., model XGP001B) is evenly mixed with the granular fertilizer in the base fertilizer. The mixing method is to mix the nano-selenium plant nutrient with a small amount (such as 1 kg) granular fertilizers are mixed evenly, and then enlarged step by step and mixed evenly, the amount of selenium fertilizer in the mixed fertilizer accounts for more than 10% of the mixture ratio, and the following fertilizer mixing methods are all like this. Then corn seeds and mixed fertilizer are sown into the field at the same time to realize simultaneous sowing of seed and fertilizer.

[0041] After the corn seedlings are established and before jointing, topdressing is generally carried out when 5-6 leaves of the plant are visible. At this time, the topdressing fertilizer is mainly nitrogen fertilizer (such as urea). Evenly mix 2 kilograms of nano-selenium plant nutrients (...

Embodiment 3

[0046] When sowing corn, 5 kilograms of nano-selenium plant nutrients (produced by Suzhou Selenium Valley Science and Technology Co., Ltd., model XGP001B) are evenly mixed with the granular fertilizer in the base fertilizer. The mixing method is to mix nano-selenium plant nutrients with a small amount (such as 1 kg) granular fertilizers are mixed evenly, and then enlarged step by step and mixed evenly, the amount of selenium fertilizer in the mixed fertilizer accounts for more than 10% of the mixture ratio, and the following fertilizer mixing methods are all like this. Then corn seeds and mixed fertilizer are sown into the field at the same time to realize simultaneous sowing of seed and fertilizer.

[0047] After the corn seedlings are established and before jointing, topdressing is generally carried out when 5-6 leaves of the plant are visible. At this time, the topdressing fertilizer is mainly nitrogen fertilizer (such as urea). Evenly mix 10 kg of nano-selenium plant nutri...

Abstract

The invention discloses a high-selenium corn straw and a cultivation method and application thereof. The content of selenium in the high-selenium corn straw is between 0.5 and 200 mu g/kg, and the organic selenium content is more than or equal to 70 percent. The cultivation method comprises the following steps of: simultaneously sowing corn seeds and fertilizers into fields; fertilizing in a row spacing application mode after the final singling of corns and before the stem pushing of the corns; and fertilizing in a hole application mode within 10 to 15 days before corn tassels are sprouted. A fertilizer is mixed with an effective amount of nano selenium plant nutrition agent when the fertilizer is applied in any fertilization step. The high-selenium corn straw has stable selenium content and can be used as a selenium-enriched animal feed so as to supply safe selenium supplementing fowl and livestock products to humans. The method has high maneuverability; and by the method, standardized production can be realized, and the stability of the content of the selenium in the produced corn straw is ensured.

Description

technical field [0001] The invention relates to a high-selenium corn stalk, a cultivation method and application of the high-selenium corn stalk, and belongs to the technical field of agricultural fertilization and feed application. technical background [0002] Selenium is an essential trace element for animals and the human body. Selenium deficiency will seriously affect human health. Selenium can improve human immunity, scavenge free radicals, protect optic nerve, heart and liver, etc., and can prevent diabetes, cardiovascular and cerebrovascular diseases, liver diseases, cataracts, arthritis, Keshan disease, Kaschin-Beck disease and other major diseases. Selenium is also a powerful antioxidant, and its synergistic effect with vitamin E is known as the "golden partner" for scavenging free radicals and anti-oxidation. Selenium is known as "the fire of life" and "the king of anti-cancer". [0003] The form of selenium is often divided into organic selenium and inorganic se...
