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 needs to input larger labor costs; need to use a large amount of selenium in the production process, wheat 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 nutrient absorption organs. , the absorption capacity is limited, inorganic selenium is highly toxic, and the unabsorbed residual inorganic selenium has a greater safety hazard
Chinese patent CN 102219586A "A Special Seed Fertilizer Rich in Zinc and Selenium for Wheat and Potatoes" discloses a kind of fertilizer that mixes wheat seeds well with organic fertilizers containing sodium selenite and zinc sulfate, then sows them and applies them deeply to enrich the wheat grains. The method of selenium and zinc-enriched, the weak point of this method is: no matter winter wheat or spring wheat, need watering several times to meet the requirement of seed water absorption in a certain period of time after sowing to promote germination, rooting, sodium selenite and zinc sulfate are soluble In addition, because the root system is the main absorption organ of crops, the period of wheat’s strong absorption of trace elements is from the tillering stage to the grain maturity stage, while the growth of wheat is very small or basically does not grow during the winter, and it is very Obviously, the trace element selenium and zinc in the special seed fertilizer described in this method are only absorbed by the wheat root system after the wheat seedlings turn green and tiller in spring, and the utilization rate of selenium and zinc is very low.

Embodiment 1

[0023] Field implementation site: Weigang Town, Bozhou City, Anhui Province. The soil is wheat field soil developed on the basis of sandy loam, with 6.2% soil organic matter, 55 mg / kg of hydrolyzed nitrogen, 17 mg / kg of available phosphorus, and 138 mg / kg of available potassium.

[0024] Wheat for testing: the wheat variety is Wanmai 52.

[0025] In this example, the wheat was sown on October 12, fertilized and irrigated conventionally, jointing began on March 15 of the following year, shallow water was poured on March 17 to keep the soil moist, and every other row of wheat was excavated at a depth of 10 to 15 cm on the same day Mix the wheat compound fertilizer and selenium-enriched zinc-iron iron chelate fertilizer and apply them to the ditch, and then cover with wet soil. In the control group, only wheat compound fertilizer was applied.

[0026] Wheat compound fertilizer consists of ammonium bicarbonate, superphosphate and potassium chloride. The application rate of ammon...

Embodiment 2

[0035] Field implementation location: Damiao Town, Guoyang County, Anhui Province. The soil is wheat field soil developed on the basis of sandy loam. The soil organic matter is 6.5%, hydrolyzed nitrogen is 59 mg / kg, available phosphorus is 19 mg / kg, and available potassium is 157 mg / kg.

[0036] Wheat for testing: The wheat variety is Zhengmai 7698.

[0037] In this example, the wheat was sown on October 19, fertilized and irrigated conventionally, jointing began on March 18 of the following year, shallow water was poured on March 20 to keep the soil moist, and every other row of wheat was excavated at a depth of 10 to 15 cm on the same day In the furrows, the experimental group and the control group were all applied with the same fertilizer as in Example 1. The specific application rate of selenium-rich zinc-iron chelate fertilizer was shown in Table 2-1. Other fertilizer components and application rates and production process and implementation Same as Example 1, the content...

Embodiment 3

[0045] Field implementation location: Damiao Town, Guoyang County, Anhui Province. The soil is wheat field soil developed on the basis of sandy loam. The soil organic matter is 6.6%, hydrolyzed nitrogen is 59 mg / kg, available phosphorus is 22 mg / kg, and available potassium is 149 mg / kg.

[0046] Wheat for testing: The wheat variety is Zhengmai 7698.

[0047] In this embodiment, wheat was sown on October 19, conventionally fertilized and irrigated, and jointing began on March 18 of the following year. On March 20, every other row was excavated with 10-15 cm deep grooves, and wheat compound fertilizer and selenium-enriched zinc Mix the iron chelate fertilizer and apply it to the ditch, and then cover it with wet soil. The control group was fed with wheat 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...

Abstract

The invention discloses a cultivation method for wheat rich in Se, Zn and Fe. The cultivation method comprises the following steps: in a wheat elongation stage, a chelate fertilizer rich in Se, Zn and Fe is applied into soil in which wheat is planted, the chelate fertilizer rich in Se, Zn and Fe comprises chelate selenium salt, chelate zinc salt and chelate ferric salt, the chelating agent of the chelate selenium salt is amino acid, and the chelating agent of the chelate zinc salt and the chelate ferric salt is EDTA (Ethylene Diamine Tetraacetic Acid); the application rate of the chelate fertilizer rich in Se, Zn and Fe is calculated according to the Se, Zn and Fe in the chelate fertilizer, the application rate of the element Se is 0.2 to 0.6 gram / mu, the application rate of the element Zn is 60-105 gram / mu, and the application rate of the element Fe is 110-160 gram / mu. According to the cultivation method provided by the invention, while the chelate fertilizer rich in Se, Zn and Fe is applied, a compound fertilizer for wheat is also applied. According to the cultivation method provided by the invention, by compared with a control group in which a fertilizer only containing one or two elements (Se, Zn and Fe) is applied, and a control group in which only the compound fertilizer for wheat is applied, an experimental group in which the fertilizer containing the three elements of Se, Zn and Fe is applied, can produce wheat flour of which the contents of Se, Zn and Fe are increased greatly.

Description

technical field [0001] The invention relates to a method for cultivating wheat, in particular to a method for cultivating wheat 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 hu...
