Embodiment 1

[0028] Field implementation location: Weigang Town, Bozhou City, Anhui Province, with 7.2% soil organic matter, 58 mg / kg of hydrolyzed nitrogen, 21 mg / kg of available phosphorus, and 155 mg / kg of available potassium.

[0029] Corn for testing: the variety of corn is Wanyu No. 9.

[0030] In this embodiment, corn was sown on June 10, conventionally fertilized and managed, earing began on July 17, watered on July 18, and every other row of corn was excavated with 10-15 cm deep furrows on the same day, and the corn Compound fertilizer and selenium-enriched zinc-iron chelate fertilizer are mixed and applied to the ditch, and then covered with wet soil. The control group only applied corn compound fertilizer.

[0031] Corn compound fertilizer consists of ammonium bicarbonate, superphosphate and potassium chloride. The application rate of ammonium bicarbonate is 15 kg / mu, the application rate of superphosphate is 15 kg / mu, and the application rate of potassium chloride is 10 kg / mu. ...

Embodiment 2

[0040] Field implementation location: Damiao Town, Guoyang County, Anhui Province, soil organic matter 6.7%, hydrolyzed nitrogen 55 mg / kg, available phosphorus 20 mg / kg, available potassium 145 mg / kg.

[0041] Corn for testing: the variety of corn is Yuyu 34.

[0042] In this example, the corn was sown on June 12, fertilized and managed conventionally, earing began on July 16, watered on July 17, and a 10-15 cm deep trench was excavated every other row of corn on the same day. All apply the fertilizer identical with embodiment 1 component with control group, the concrete application rate of selenium-rich zinc-iron chelate fertilizer is shown in Table 2-1, and other fertilizer components and application rate and production process are identical with embodiment 1, and the produced The contents of selenium, zinc and iron in corn are shown in Table 2-2.

Embodiment 3

[0049] Field implementation location: Damiao Town, Guoyang County, Anhui Province, soil organic matter 6.8%, hydrolyzed nitrogen 57 mg / kg, available phosphorus 22 mg / kg, available potassium 148 mg / kg.

[0050] Corn for testing: the variety of corn is Yuyu 34.

[0051] In this embodiment, corn was sown on June 12, conventionally fertilized and managed, earing began on July 17, watered on July 18, and every other row of corn was dug a deep 10-15 cm furrow on the same day, and the corn Compound fertilizer and selenium-enriched zinc-iron chelate fertilizer are mixed and applied to the ditch, and then covered with wet soil. The control group was fed with corn compound fertilizer and selenium-enriched chelate fertilizer. The specific application rates of selenium-rich zinc-iron chelate fertilizer and selenium-rich chelate fertilizer are shown in Table 3-1. Other fertilizer components, application rates and production process are the same as in Example 1. The contents of selenium, z...

Abstract

The invention discloses a method for cultivating corns rich in selenium, zinc and ferrum. During heading period of the corns, chelating fertilizer rich in selenium, zinc and ferrum is applied to soil for planting the corns, the chelating fertilizer rich in selenium, zinc and ferrum comprises chelating selenium salt, chelating zinc salt and chelating ferrum salt, the chelating agent of the chelating selenium salt is amino acid, and the chelating agent of the chelating zinc salt and the chelating agent of the chelating ferrum salt are ethylenediaminetetraacetic acid; the application amount of the chelating fertilizer rich in selenium, zinc and ferrum is determined according to selenium elements, zinc elements and ferrum elements in the chelating fertilizer, the application amount of the selenium elements ranges from 0.8 g/mu to 1.5 g/mu, the application amount of the zinc elements ranges from 80 g/mu to 150 g/mu, and the application amount of the ferrum elements ranges from 150 g/mu to 200 g/mu. The corn compound fertilizer is applied while the chelating fertilizer rich in selenium, zinc and ferrum is applied. Compared with a control group where only the fertilizer with one or two kinds of the selenium elements, the zinc elements and the ferrum elements is applied and a control group where only the corn compound fertilizer is applied, the content of selenium, the content of zinc and the content of ferrum in the corns harvested in the experimental group with the chelating fertilizer rich in selenium, zinc and ferrum applied are greatly improved.

Description

technical field [0001] The invention relates to a method for cultivating corn, in particular to a method for cultivating corn enriched in selenium, zinc and iron. Background technique [0002] Selenium, zinc, and iron are essential trace elements for the human body, and are essential nutrients in the daily dietary nutrition balance standard of the Chinese Nutrition Society. Selenium plays an important role in enhancing human immunity, anti-oxidation, and regulating protein synthesis. Zinc deficiency in the human body will lead to decreased immunity, resulting in Keshan disease, Kashin Joint, coronary heart disease and other diseases. Zinc participates in the metabolism of various nutrients in the human body and is a component of various enzymes or functional proteins. Zinc deficiency in the human body will lead to decreased immunity, anorexia, dysplasia, and mental decline. Iron is a component of hemoglobin, which directly participates in the energy metabolism of the huma...
