Problems solved by technology

[0008] However, the above method does not give accurate quantitative values ​​for the amount of selenium content and the form of selenium, so whether it can achieve safe and effective scientific supplementation of selenium in line with national standards still needs further research.

Embodiment 1

[0025] The quantitative selenium-enriched planting method of embodiment 1 carrot soil selenium fertilizer

[0026] (1) Seed treatment

[0027] Before sowing, dry the seeds for 1-2 days. After soaking the seeds in warm water at 15-20°C for 3 hours, put them into clean and moist gauze for germination, keep the temperature between 20-25°C, and spray water at the right time to keep the seeds moist. When most of the seeds are white, they can be sown.

[0028] (2) plowing

[0029] Before sowing, apply 400-500kg of mixed fertilizer of decomposed chicken manure and decomposed soybean meal (weight ratio: 4:1) per mu of land, so that the mixed fertilizer can be evenly sprinkled into the soil. The cultivated land is 28-30cm deep and 40-50cm wide, forming ridges.

[0030] (3) Apply selenium fertilizer to the soil

[0031] a: The acidity and alkalinity of the field soil was tested before the selenium fertilizer was applied to the soil.

[0032] b: Adjust the acidity and alkalinity of ...

Embodiment 2

[0041] The quantitative selenium-enriched planting method of embodiment 2 carrot foliage application selenium fertilizer

[0042] (1) Seed treatment

[0043] Before sowing, dry the seeds for 1-2 days. After soaking the seeds in warm water at 15-20°C for 3 hours, put them into clean and moist gauze for germination, keep the temperature between 20-25°C, and spray water at the right time to keep the seeds moist. When most of the seeds are white, they can be sown.

[0044] (2) plowing

[0045] Before sowing, apply 400-500kg of decomposed chicken manure and decomposed soybean meal (weight ratio: 4:1) mixed fertilizer per mu of land, so that the fertilizer can be evenly spread into the soil. The cultivated land is 28-30cm deep and 40-50cm wide, forming ridges.

[0046] (3) Sowing

[0047] The sowing depth of each ridge is 3-4cm, and the covering soil is rolled. After emergence, thin the seedlings at a plant spacing of 3-4 cm.

Abstract

The invention relates to a quantitative selenium-enriching carrot planting method. The quantitative selenium-enriching carrot planting method comprises the following steps of seed processing, soil turnover, selenium fertilizer application in soil or selenium fertilizer application on leaf surfaces, field management and harvesting. A selenium fertilizer is prepared from sodium selenite, sodium selenite, zinc sulfate, calcium nitrate, magnesium sulfate, bentonite and an acidity regulator. The quantitative selenium-rich carrot planting method can achieve a quantitative selenium-enriching effect, and multiple gradient choices are provided. The selenium content in the soil can meet the demand of plant growth and also meet the national standard, and the planting soil is not polluted. The phenomenon that seedlings are burnt does not occur after the selenium fertilizer is applied, and the emergence rate is greatly improved compared with a control group. The quantitative selenium-enriching carrot planting method is conductive to yield improvement, and the yield is 20% higher than the yield of common carrots.

Description

technical field [0001] The invention belongs to the technical field of carrot planting, and in particular relates to a planting method suitable for quantitatively enriching selenium in northeast carrots. Background technique [0002] In 1973, the WHO (World Health Organization) expert committee declared that selenium is one of the essential trace elements for the human body. Since then, selenium is the third largest micronutrient and health care element after iodine and zinc, and enjoys the reputation of "the king of anti-cancer" and "natural antidote". Modern studies have shown that selenium not only has the functions of anti-oxidation, anti-aging, improving human immunity, and antagonizing heavy metals, but also plays an important role in anti-cancer, preventing cardiovascular and cerebrovascular diseases, and reducing the incidence of diabetes and Keshan disease. In addition, studies have also pointed out that adequate selenium supplementation has health care functions, ...
